A Brief History on the Pest Control Adviser and Certified Crop Adviser Programs

Longtime Crop Adviser Helped Increase Job Market for CCA Industry

By Brian German, Associate Broadcaster

 

The Certified Crop Adviser Program (CCA) was introduced in 1992 as a means to address the increased concerns regarding agriculture’s contributions to a variety of environmental issues.  By 1994, the CCA program was fully established with the support of the California Department of Food and Agriculture, along with the American Society of Agronomy and the California agricultural industry. The program was designed to raise the awareness and professional standards of individuals who make recommendations on agricultural fertilizers, pesticides and related products. 

Allan Romander has a long history with the CCA program, having joined the CCA Board in 2004. “I am currently with the Certified Crop Adviser Program in California, and Arizona I might add. I am a consultant with the organization. I just concluded my term as ICCA Chair and past Chair,” Romander said.

A Pest Control Adviser (PCA) since 1979, Romander joined the California CCA Board in 2004 and was instrumental in helping to develop a marketing program that nearly doubled the number of CCAs in California in a little less than six years. 

California is one of just a few states that require people who advise farmers on pest control management to be licensed as a Pest Control Adviser.  Amidst rising public concerns regarding pesticide use on California farms, the PCA program was launched in 1973 to ensure that those who make pesticide recommendations are both qualified and knowledgeable. “But that only certified them in the area of pest management,” Romander said. “It never said anything about their competency in the area of crop management or soil or water management.”

Consultants historically have just held a Pest Control Adviser’s license,” Romander said. Over time, farmers began to ask their PCAs for guidance on multiple subjects outside of pest control, such as fertilizers and irrigation. 

“That’s where the Certified Crop Adviser Program comes in and picks up where the PCA program leaves off.  It covers those categories and certifies to a grower that [the adviser] has competency in those other areas,” Romander said.

Currently, there are close to 4,000 EPA-licensed Pest Control Advisers in California.  Romander noted, “Eighty-five percent of the Certified Crop Advisers in California are also Pest Control Advisers. So it’s a well-established program and well-respected throughout not only the United States, but North America and the rest of the world.”

US Citrus Industry Working Together on ACP, HLB Funding

Critical ACP, HLB Funding Comes Only After Industry Helps Itself

By Patrick Cavanaugh, Farm News Director

 

State Citrus Mutuals in California, Texas and Florida are diligently working in Washington, D.C., for $10 to 12 million in annual funding to help their citrus regions fight Asian Citrus Psyllid (ACP) infestation and Huanglongbing (HLB), the disease that ACPs vector.

The three Citrus Mutuals have collaborated well for the half dozen years of the American ACP invasion. Initially, the Florida Citrus Mutual team developed the Citrus Health Response Program (CHRP),” said Joel Nelsen, president of California Citrus Mutual.

“They initiated it at a very minor funding level. However we sat down with them and said, ‘Look, this is an opportunity to ensure that all of the U.S. citrus industry can work together to protect itself from Huanglongbing.’ They were gracious enough to say okay. We exerted our leadership because we had people in positions in Washington who could be very beneficial to this,” Nelsen said.

“Initially it was a Florida/California effort. We said we need to double the size of the CHRP program and allocate more dollars to California, some to Texas, and some to Arizona. Now everybody is participating to the extent that they can. Today, it is still a Florida/California effort and a Florida/California-run program in partnership with USDA.

Nelsen said those involved are working hard to protect the citrus industry, and not just chasing a problem. Funding has been helpful to California. Only after the industry does all it can, will the state expect the federal government to help.

“It’s true for all three states’ industries,” Nelsen said. Unfortunately, Texas made a mistake. They did not have a policy in place to immediately remove an HLB-infected tree. As a result, they have an HLB infection spreading.”

“Texas is being adversely impacted on the dollar level. We don’t want to see that industry die, so there is a partnership that does exist on behalf of our colleagues,” Nelsen said. “We can’t afford to make mistakes like that.”

“In order to justify the continued progress of funding on an annual basis we are going to have to continue looking ahead, taking the steps necessary and doing what is needed to protect the citrus industry from the spread of Asian Citrus Psyllid and Huanglongbing.”

“We definitely have to show progress. We can’t ask homeowners to spray their trees if in fact we are not spraying ours. We can’t ask the federal government to continue helping us looking for ACPs if we are not willing to tarp our trucks to stop the spread of it. If we’re not willing to do a coordinated spray program then why should the government help us in finding HLB? If we are allowing snake oil merchants to conduct research projects, why should the federal government fund those?

Groundwater Policy Confusion at State Level

WGA’s Puglia on Sacramento’s Muddled Potable Groundwater Policy

By Patrick Cavanaugh, Farm News Director

 

Groundwater Quality

Many residents in California’s agricultural regions rely on groundwater from private wells rather than from municipal supplies for clean drinkable water. Test results on many of these wells have revealed excess nitrates and other dangerous elements. Indisputably, all state residents deserve clean potable water.

Who is Responsible?

Cris Carrigan, director of the State Water Resources Control Board (SWRCB) Office of Enforcement, issued confidential letters to growers in two regions, Salinas Valley and the Tulare Lake Basin, demanding these farmers supply potable water to the citizens in need.

“The letter represents a legal proceeding by the Office of Enforcement,” said Dave Puglia, executive vice president of the Western Growers Association (WGA). “Why they desire to keep it confidential is something they would have to answer, but I think sending that many letters to a community of farmers is a pretty good guarantee that it won’t remain confidential.”

The first letters went to growers in Salinas one year ago. “Although there has been some advancement of the discussions between some of the growers in the Salinas Valley and the Office of Enforcement,” Puglia said, “I don’t think it’s been put to bed yet.”

Which Groundwater Supply?

“It’s critical to distinguish between entire communities in need of [municipal] drinking water assistance and domestic well users whose wells have nitrate issues. Those are two different things.”

“It’s important to keep that distinction. The state has spent money and is advancing programs to provide clean drinking water to small community water systems that don’t have that capability, and that’s appropriate,” Puglia clarified. “That is not what we’re talking about here.”

“We’re talking about a smaller number of individuals whose domestic wells are contaminated with nitrates. These are people not served by a municipal system.”

“Again, these are people who depend upon wells located on property that has been previously used for agriculture, and the groundwater has nitrate levels that exceed state limits. We are talking about one to maybe five household connections serviced by one well, so it is a very small service of water.”

“This is a much smaller universe than we’re accustomed to talking about when we talk about nitrate levels in drinking water. It often conjures up the image of municipal water systems that [cannot be treated.] That is a different problem entirely, and the state has made some advances in tackling that problem and needs to do more. This is something of a smaller nature, but the cost-impacts could be very significant.”

Replacement Water

“There are different ways of providing replacement drinking water for some period of time until those folks can be connected to municipal water service. That really should be the objective here; if a domestic well is that far gone, we should get these folks connected to a municipal water service,” Puglia said.

The bigger question is what should the state’s replacement water policy be for individuals whose wells are contaminated with nitrates? Puglia said, “The state of California and the federal government encouraged farmers to apply nitrogen for decades to produce something we all need—nutritious food preferably from American soil.

“Now, with the benefit of scientific advancement, we discover that much of that nitrogen was able to leach below the root zone and enter the groundwater supply.”

Groundwater Policy Debate

“This was not an intentional act of malice to pollute groundwater. These were farmers doing [best practices] to provide food as they were coached and educated by our universities and by our state and federal governments.” Puglia said the state looks at this problem as if it were a case of industrial pollution and growers should be punished.

“That is fundamentally not what this is. I think it’s really important for the state of California, for Governor Jerry Brown, and for his administration, to stand back, take a hard look at this problem and differentiate it from industrial pollution, because it is not the same. They need to go back to the SWRCB’s recommendations for best solutions,” Puglia declared.

“Three or four years ago, the Water Board recommended to the legislature the most preferable policy solution for the public good was to have everyone chip in for clean water. This is just like how all of us pay a small charge on our phone bill for the California Lifeline Service for folks who can’t afford phone service,” Puglia said.

“If we have a connection to a water system, we would all pay a small charge on our water bill to generate enormous amounts of revenue that the state could use to fix not only nitrate contamination but all of the other contaminants in the state’s drinking water supplies. Many of those contaminants are far more hazardous than nitrate, such as Chromium-6 (a carcinogen), arsenic and other toxins that are industrial pollutants, that pose a much greater health risk.”

Puglia explained that in this case, the state bypassed its own preferred ‘public goods charge‘ policy option with regard to water. The state bypassed its second preferred policy option, which is a small tax on food. The state bypassed its third preferred policy option, a fertilizer tax. “State officials from Governor Brown’s office went straight to the policy option the State Water Board said it did not prefer, which is to target farmers.”

Complex Contamination Needs a Holistic Solution

Now the big question is who ought to bear the burden of paying for that solution, both on a temporary basis and then on a permanent basis? Puglia said, “The state itself and the State Water Board itself already projected three policy options that would be preferable.”

“These options would have spread the cost very broadly among Californians through three different mechanisms, seemingly in recognition of the fact that farmers were doing the right thing for decades in growing food using fertilizer. Fertilizer that contains nitrogen has been essential to growing food since the dawn of humankind.”

Puglia said that nitrate contamination of drinking water is a legitimate problem in California. However, it pales in comparison to the presence of industrial pollutants in drinking water supplies that are highly carcinogenic and highly toxic. Such water sources throughout southern California and parts of the Bay Area can no longer be used.

Rather than looking at this holistically, Puglia said, Governor Brown’s administration has focused exclusively on one contaminant, nitrate, that affects a relatively small number of Californians and is targeting one small group of Californians to pay for replacement water.  A holistic perspective would determine that California has a severe problem with its drinking water due to contamination by different toxic substances that vary in different regions of the state and that affect many Californians diversely.

“The obvious way to ensure people have safe, clean drinking water,” Puglia said, “is a broad solution, like a fee on water connections that we all pay. And that has been, in fact, the SWRCB’s preferred solution.”

“And, yet, we have made no effort as a state to move that policy forward. Instead, we are defaulting to running over a small group of people who are relatively defenseless, politically.”

“More importantly some people in the Governor’s Office, as well as leaders and secretaries in the Governor’s administration, including Matt Rodriquez, secretary, CalEPA, expressed some agreement with our position and sympathy with our predicament. Yet the letters continued to go out,” Puglia said.

Select Growers Asked to Remediate Nitrates in Water

Cris Carrigan Opens Dialogue With Growers about Nitrates in Water

 

By Patrick Cavanaugh, Farm News Director

 

Over the last year, 19 Salinas Valley growers, and recently 26 citrus growers on the east side of Tulare County, each received a confidential letter from Christian Carrigan, director, State Water Resources Control Board (SWRCB), Office of Enforcement. The letter constituted an invitation to a meeting to discuss the provision of uninterrupted replacement water to communities and individuals who rely on the region’s groundwater which contains too many nitrates.

Invitation recipients are growers who farm larger tracts of agricultural land in regions identified to have elevated nitrate-contaminated groundwater based on historical evidence. The ‘Harter Report,’ officially submitted to SWRCB in 2012 as, “Addressing Nitrate in California’s Drinking Water,” reinforced the nitrate problem.SWRCB nitrates

The letter presented recipients with a choice: provide replacement potable water to disadvantaged communities with substandard drinking water or face a mandated Cleanup and Abatement Order that would require the development, installation, and ongoing operation of expensive reverse-osmosis water treatment systems or other fixes.

“We’re looking at ways to have a broader dialogue with the larger agricultural community,” Cris Carrigan explained. “I sent the confidential letter to a group of agricultural land owners in Tulare County and because I offered to maintain its confidentiality, I really don’t want to talk about the contents of it now.”

“I should be clear, this is an action by the Office of Enforcement at the State Water Board,” Carrigan said. “It is led by Jonathan Bishop, chief deputy director. I am a legal officer and he’s my client, the decision-maker at the Board.”

“We have not talked about this with the board members, Tom Howard, executive director, or Michael Laufer, chief counsel,” Carrigan clarified. “We have preserved their neutrality by not communicating with them about this action in case we need to do an adjudicatory proceeding. We did the same thing in Salinas.”

Carrigan noted that his office does not want this to go into an adjudicatory proceeding. “We are really set up, primarily, to try and resolve this in a mutually acceptable and cooperative way. We think there are ways to do that. We’ve learned a lot from engaging with the agricultural community in Salinas. Now we hope to apply those lessons and learn some new things in Tulare County.”

Carrigan commented that he is having the right kind of dialogue with farmers. “We’re talking about the right kinds of things. Again, I understand that nitrogen means food, food means jobs. We need to have a scientifically defensible way to bring back [water] resource restoration, so that our aquifers can become clean again.”

“In the meantime, we have to prevent people from being poisoned by bad water. That is what this is all about,” Carrigan said.

“Registrations are at an all-time high,” she continued. “We’ve actually sold out the entire show as well as registrations with 1600 attendees. There were just a handful of walkups that we unfortunately just couldn’t accommodate today. We are excited and looking forward to continuing to have a high professional continuing education program as well as an exhibit hall here today.”

“This year’s theme is ‘Fighting the Fear, Feeding the Nation,’ said Anderson, “so we’ll have Captain CAPCA as well as Doctor Foe here this morning.”

Click here to meet Captain CAPCA and Doctor Foe on this CAPCA ‘NEWS’ video!

 

Anderson reflected, “You know for us, CAPCA really represents the Pest Control Advisors (PCAs) for production ag and turf and ornamental. As a requirement for their continuing education, they need 40 hours in order to renew [their certification]. For us, bringing together continuing education as well as networking is so valuable for them as they move into the new year.”

 

Some “Top Gun” people speaking this year, according to Anderson, “are obviously some of our main sponsors. Bayer CropScience and FMC Corporation are both doing high-level presentations. We also have Kern County agricultural commissioner Ruben Arroyo talking about the new proposed regulations for buffer zones around schools, so that’s going to be a great conversation starter for all of our members.”

 

“We appreciate all of the support we receive,” Anderson stated. “It’s so valuable for us. We exist because of volunteers and we exist because of our membership. We are grateful for all of them.”


The California Association of Pest Control Advisers (CAPCA) represents more than 75% of the nearly 4,000 California EPA licensed pest control advisers (PCAs) that provide pest management consultation for the production of food, fiber and ornamental industries of this state.

CAPCA is dedicated to the professional development and enhancement of our member’s education and stewardship, which includes legislative, regulatory, continuing education and public outreach activities.

CAPCA membership covers a broad spectrum of the industry including agricultural consulting firms, U.C. Cooperative Extension Service, city, county and state municipalities, public agencies, privately employed, forensic pest management firms, biological control suppliers, distributors, dealers of farm supplies, seed companies, laboratories, farming companies and manufacturers of pest management products.

Initial Walnut Irrigation Can be Delayed

Walnut Irrigation Research Update

By Brian German, Associate Broadcaster

 

First springtime walnut irrigation can be delayed, according to a UC Cooperative Extension team in Tehama County working on some fascinating research regarding irrigation practices. Allan Fulton is an Irrigation and Water Resource Advisor who covers Tehama, Colusa, Shasta and Glenn counties. “We actually just finished one of our irrigation experiment harvests this weekend. It was looking at early season water management decisions, basically deciding when to begin the irrigation season,” Fulton said.

Growers typically begin irrigating their walnuts sometime between late April and early May. In order to be as thorough as possible in their experiment, Fulton and his team have been pushing the limits beyond what most growers would ever consider. “We had some treatments that got no irrigation until almost the end of June,” Fulton explained.

Now in its third year, the research experiment is generating information that will provide a variety of benefits. “The whole motivation is to avoid possible injury to the trees from irrigating too much, too early, from lack of aeration and damage to the root system,” Fulton said. Delayed irrigation, while having no impact on yield or nut size, can also provide a bit of water savings. “We’re trying to look for the sweet spot,” with less intensive early season irrigation in favor of root health, tree health and disease prevention.

California walnut orchard, walnut irrigationThe research is being conducted in the northern Sacramento Valley primarily using the Chandler variety of walnut trees. Fulton has spent some time working in the San Joaquin Valley as well and understands different weather conditions can be a significant factor when applying their findings to other regions. “Our spring rainfall is quite a bit different than other walnut growing areas. Usually we’ve got an added source of water that sometimes you might not have in the southern San Joaquin Valley,” Fulton noted. From his experience, he suggested growers could usually wait until “the first week of May in most years, before really getting pressed for irrigation.”

The location of the research exposes groves to the opportunity to receive “more rain during the dormant season with a better chance at a deeper profile in moisture before you ever break dormancy,” Fulton said. More regional rainfall is possible in the spring as well, while the trees are growing.

The information gathered so far indicates growers should not jump the gun on springtime irrigation, particularly if there is still any kind of standing water issues. “The data is starting to suggest that you’ve got some room. You don’t have to irrigate at the first sign of heat; you can use a little bit of the stored moisture coming out of winter,” Fulton said. He also noted “It’s a lot more difficult to recover from a damaged tree with a sick roots system,” than it is to recover from a lack of early season irrigation.

ACP Spread in Bakersfield Area, Ingenious Research Proceeds

Ingenious Research Effort to Fight ACP Spread with Natural Predators

 

By Joanne Lui, Associate Editor

Beth Grafton-Cardwell, Cooperative Extension specialist, University of California, Riverside Department of Entomology

As we have reported in-depth before on California Ag Today, the Asian Citrus Psyllid (ACP) is a tiny, mottled brown insect that poses an ever-increasing threat to the state’s robust citrus industry, as well as to residential citrus trees. The pest can spread a bacterium known as Huanglongbing (HLP) that is fatal to citrus trees. The disease has nearly shut down Florida’s citrus industry.

Beth Grafton-Cardwell, cooperative extension specialist in integrated pest management, UC Riverside Department of Entomology, explained the significance of the recent ACP spread to Bakersfield. “That is really problematic because it’s mostly in the urban areas. It’s very difficult to find, to control and to stop that spread. It’s going to move out from that region into the local citrus orchards, and so there are lots of meetings and discussions right now to mobilize growers to get treatments to help protect their citrus orchards against the psyllid.”

To contain the ACP problem, Grafton-Cardwell stated, “There are traps everywhere, but the traps are not terribly efficient. So, we really need to carefully examine groves and flush [new leaf growth] for the nymph form,” she said.

According to Agriculture and Natural Resources, University of California’s Statewide Integrated Pest Management Program:

Adults typically live one to two months. Females lay tiny yellow-orange almond-shaped eggs in the folds of the newly developing “feather flush” leaves of citrus. Each female can lay several hundred eggs during her lifespan.

ACP UC IPM

The eggs hatch into nymphs that are wingless, flattened, yellow or orange to brownish, and 1/100 to 1/14 inch long. Nymphs molt four times, increasing in size with each nymphal stage (instar), before maturing into adult psyllids. The nymphs can feed only on soft, young leaf tissue and are found on immature leaves and stems of flush growth on citrus.

Save Our CitrusThe nymphs remove sap from plant tissue when they feed and excrete a large quantity of sugary liquid (honeydew). Each nymph also produces a waxy tubule from its rear end to help clear the sugary waste product away from its body. The tubule’s shape—a curly tube with a bulb at the end—is unique to the Asian citrus psyllid and can be used to identify the insect.

Grafton-Cardwell and other experts are concerned because once the ACP becomes established in urban areas, it is difficult to eradicate. “It starts spreading into the commercial citrus, and we’re off and running,” she commented.

bayer-save-our-citrusIn a ingenious effort to control the spread of the psyllid, trained teams of entomologists have imported Tamarixia radiata, a tiny wasp that naturally preys on ACP, from Pakistan to research and release in California. A cooperative effort of the University of California Riverside, Citrus Research Board, United States Department of Agriculture and California Department of Food and Agriculture, researchers are also exploring the effectiveness of another beneficial insect called Diaphorencyrtus aligarhensis to assist Tamarixia with control of the Asian citrus psyllid. To see where Tamarixia and Diaphorencyrtus have been released, visit this University of California’s website map at, “Distribution of ACP, HLB and Parasites in California,” and turn on the parasite layers.
Grafton-Cardwell said, “They’re going to inundate that area,” with natural ACP predators, “so hopefully that will push back a little bit.”

Working with Agriculture to Meet Environmental Goals

Working with Stewards of California’s Farmland to Meet Environmental Goals

By Patrick Cavanaugh, Farm News Director

 

If you give a farmer a goal, they will most likely strive to meet it—even exceed it—as long as it fosters great stewardship of their land and allows them to sustainably farm into the future.

Environmental Defense Fund (EDF) logo

Eric Holst, associate vice president of the Environmental Defense Fund‘s working lands program, and an expert in developing strategies for environmental management on working forest, farms, and ranches, has an important view of the California Agriculture industry. “It’s an incredibly important industry. It’s greater than $56 billion net for California farmers. I think, even more important than the monetary value, is the land and the water that it touches,” said Holst.

Holst’s career has focused on improving livelihoods and environmental conditions in rural places in the U.S. and Latin America. Appointed as a member of the California Board of Food and Agriculture by Governor Jerry Brown for his ability to effectively communicate with a wide variety of constituents on difficult environmental issues, Holst elaborated, “Farmers and ranchers in California have a lot of influence on how we manage land, how we manage our landscapes, how we manage our waterways. It’s incredibly important to weigh in on policy issues that relate to agriculture in California.” california-farmland

Based in Sacramento, Holst knows how pervasive California agriculture is, spanning the state from the Mexican border to the Oregon border. “About 45% of California is in privately-held working lands—land managed by farmers, ranchers, and forestland owners,” Holst noted. Holst and his team interfaced with these private landowners to map a big part of it.

Holst, who also serves as director of the Forest Stewards Guild and American Wind Wildlife Institute (AWWI), explained, while these landowners have a lot of freedom about how to manage their land, “It’s probably the most highly regulated place in the world in terms of environmental performance.” Despite regulatory constraint on land management decisions, Holst believes, “there’s a lot of room to make decisions that can either help or harm the environment.”

Holst reflected, “It is really an important role that we have on the CDFA Board to weigh in and try to push California in the right direction.” Ultimately, in Holst’s experience, “If you set a goal and then allow farmer, rancher or forest landowner to figure out how to meet that goal, that’s probably the best way,” said Holst.

“Conditions are different on every farm, every ranch,” Holst stated. “I think it’s important to set standards high. I think California has higher standards than just about anywhere else. We want to develop policies and implementation of policies that will give a lot of flexibility to the individual operator. That tends to be, in my experience, the system that works best,” he noted.

Fear-Based Messaging Reduces Produce Consumption – Both Organic and Conventional

New Study Finds Fear-Based Produce Safety Messaging Negatively Impacts Low Income Consumers’ Produce Consumption

 

New peer reviewed research, “Low-Income Shoppers and Fruit and Vegetables: What Do They Think?” published in Nutrition Today, shows fear-based messaging tactics used by activist groups and some organic marketers that invoke safety concerns about non-organic produce may be having a negative impact on produce consumption—fruits and veggies—among low income consumers, according to the Alliance for Food and Farming (AFF).Alliance for Food and Farming logo

Researchers at the Illinois Institute of Technology’s (IIT) Center for Nutrition Research surveyed low income consumers to learn more about what terms and information about fruits and vegetables may influence their shopping intentions. Among the key findings, misleading messaging which inaccurately describes certain fruits and vegetables as having “higher” pesticide residues results in low income shoppers reporting that they would be unlikely to purchase any fruits and vegetables – organically or non-organically grown.

illinois-institute-of-technology-institute-for-food-safety-and-health“We were surprised to see how informational content that named specific fruits and vegetables as having the highest pesticide residues increased the percentage of shoppers who said they would be unlikely to purchase any type of fruits and vegetables,” says Britt Burton-Freeman, associate professor of food science and nutrition, ITT’s Center for Nutrition Research. “The concern is that depending on the structure of the communication about pesticides and fruits and vegetables, this could turn people away from wanting to purchase any fresh produce.”

“Despite efforts by the health community, consumption of fruits and vegetables is stagnating,” says Elizabeth Pivonka, Ph.D, R.D. and president, Produce for Better Health Foundation. “This new study shows what we have been concerned about for some time, that safety fears may be another barrier to consumption of these healthy and nutritious foods. The impact of the fear-based messaging on low income consumers is especially troubling since many don’t have access or can’t afford non-Produce for Better Health, produce consumptionorganic produce.”

The findings are also concerning since the safety claims carried predominantly by groups like the Environmental Working Group (EWG) and Only Organic about pesticide residues have been repeatedly proven to be scientifically inaccurate. For the last 20 years, EWG annually releases a so-called “dirty dozen” list which urges consumers to eat only organic versions of popular produce items accompanied by misleading and unscientific claims regarding pesticide residue levels. A peer reviewed analysis of EWG’s list entitled, Dietary Exposure to Pesticide Residues from Commodities Alleged to Contain the Highest Contamination Levels and published by AFF showed that substitution of organic forms of produce for non-organic produce did not result in any decrease in risk because residue levels are so minute on these fruits and vegetables, if they are present at all.

“Their tactic clearly isn’t working and it’s actually backfiring since this research shows that consumers may react to their message by deciding not to buy any produce at all – organic or non-organic,” says Teresa Thorne of the AFF. “For the benefit of consumers, especially low income consumers, this study shows it is time for groups like EWG to rethink their strategy for promoting organics and move away from tactics intended to scare consumers from buying the more affordable and accessible produce items,” Thorne says.

john-hopkins-bloomberg-school-of-public-healthThis IIT research compliments the peer reviewed study by John Hopkins University’s Center for a Livable Future, They Just Say Organic Food Is Healthier”: Perceptions of Healthy Food among Supermarket Shoppers in Southwest Baltimore,” published in January 2015 [orig. Dec. 2014] in the journal, Culture, Agriculture, Food and Environment. Those researchers conducted interviews with study participants to learn more about the way organic food is understood within consumers’ definitions of healthy food. John Hopkins researchers also focused on low income consumers because “this group is particularly important demographically given the disparate burden of diet-related diseases they carry and the frequency of diet-related messages they receive.”

The study authors also found conflicting health and safety messages, including those about pesticide residues, were having a negative impact on consumers. Among their findings and recommendations: “The issue of organic can swamp or compete with other messages about nutrition, as evidenced by the data presented here. Perceiving that there is an overwhelming amount of sometimes contradictory information about healthy eating could make some consumers defeatist about trying to eat healthily. Given the potential implications of competing messages about healthy eating, it is important that those who want to improve food production techniques and those who want to improve nutrition cooperate to create consistent messaging about healthy eating.”

Dr. Burton-Freeman reached a similar conclusion. “Hearing that the majority of shoppers in this survey trust dietitians/nutritionists, scientists and physicians for health and safety information about fresh fruits and vegetables, this is an important opportunity for these professionals working in low-income populations. It is an opportunity to educate shoppers about organic and conventionally grown produce, particularly about best practices for washing, storing and preparing all fruits and vegetables to maximize their enjoyment and nutritional value and minimize their confusion and safety concerns.”

“Hopefully the peer-reviewed research from IIT and John Hopkins will have an impact on groups like EWG especially since the science clearly shows both organic and non-organic produce is very safe and can be eaten with confidence,” AFF’s Thorne says. “And, decades of nutritional research primarily conducted using non-organic produce shows that a plant rich diet leads to better health and a longer life. So choose either or both organic or non-organic produce, but choose to eat more every day.”


The Alliance for Food and Farming (AFF) is a non-profit organization formed in 1989 which represents organic and conventional farmers and farms of all sizes.  Alliance contributors are limited to farmers of fruits and vegetables, companies that sell, market or ship fruits and vegetables or organizations that represent produce farmers.  AFF’s mission is to deliver credible information to consumers about the safety of all fruits and vegetables.  AFF does not engage in lobbying nor does it accept any money or support from the pesticide industry.  In the interest of transparency, AFF’s entire 2011 tax return is posted on safefruitsandveggies.com.

Calcot Could Market 70 Millionth Bale this Year

Calcot Ltd. Chairman Talks California Cotton at 89th Annual Meeting

By Patrick Cavanaugh, Farm News Director

Calcot Ltd., a democratically-run cotton marketing cooperative owned by 1,200 select cotton growers in California, Arizona, New Mexico and Texas, held its 89th Annual Meeting in Tempe, Arizona, this week. 

Gregory Wuertz, chairman of Calcot and an Arizona cotton grower, said, “The cooperative started in 1927, and it is just amazing to me that we will reach 70 million bales sometime this year.”

“That’s a lot of cotton if you think about it,” Wuertz said. “And it has a great effect on all the growers. A lot of money has been run through the organization, and we are still doing it.”

Wuertz said Calcot directors are in the field across the western cotton belt, interacting with the industry.

“We have Calcot personnel in each cotton region who are also out in the fields talking to people and bringing up questions. They just don’t stay in their office. We try to get great members, and we work really closely with gin managers and their staff. We want to be on a first-name basis,” he said.

Wuertz noted, “You have to love the lifestyle of cotton production. You get attached to the crop. You plant it in March and harvest it in November. It’s a long-term thing.”

Yet, Wuertz acknowledged, “There are ups and downs. There always are. There is always a new catastrophe because you deal with the weather and the water issues. I think you just build up a little bit of a strength and have tougher skin than maybe some growers have with other commodities.”

Many Calcot growers outside of California are in awe of California producers. 

“California has a lot more regulations,” Wuertz said. “They’re blessed with a really nice climate—just a perfect area. Our climate is a little harsher, but California people work with air quality, labor laws, and their water issues. They have to have a real sharp pencil to make all that work.”

However, Wertz says, California growers always enjoy a better per-pound price for their cotton.

“I think over the years they have developed markets, and because of their climate, they do grow a real [high] quality crop that just demands a higher price. Everybody says there’s no difference, but there is some kind of difference that is just a little better,” he said.

Wuertz explained that the Calcot cooperative is good for growers when it comes to the prices they receive.

“It is the classic cooperative idea,” he said. “It is too risky to try and peak these cotton markets. It is risky to just hold all your cotton and try to peak it at one time.”

“You have to be conservative,” he continued. “Like cotton growers are — very conservative. So you sell some and hold some and seek financing from banks for the short term. We have good tight covenants with the bank, and that’s part of our risk-management policy. We don’t want to speculate, so that is why we sell throughout the year, and we try and watch all those things.”

“We have a very strong relationship with mills and we can sell directly to them, which I think demands more of a premium for Calcot growers,” Wuertz said. “And while most cotton-spinning mills are offshore, we still have a good chunk of cotton going to some very good domestic mills, where they turn out top of the line sheets and higher-count shirts.”
