Working on Nematode Resistant California Commercial Carrot

Nematode Resistant California Commercial Carrot On Its Way?

By Jessica Theisman, Associate Editor

Phil Simon is a carrot breeder and geneticist with the USDA Ag Research Service based at the University of Wisconsin. He produces the vast majority of carrots for the consumers throughout the nation. A big goal is to find a commercial carrot variety that is root-knot nematode resistant. Nematodes are a soil-borne, microscope, worm-like organism destroying production in some fields. Through lots of research, the carrot industry is getting closer to a resistant variety.

The first resistance gene was first discovered in 1992 in a Brazilian variety that may have some genetic resistance. The resistance was discovered by using derivatives from the Brazilian variety crossed with California-adapted carrots. This is all being done with, “the idea of moving that resistance gene into a carrot that’s suitable for California in terms of shape, size, flavor, and productivity,” Simon said.

The Brazilian variety is not suited to California because it is shorter and wider. It does not look like a California carrot, and it bolts very easy, which means it flowers and goes to seed. But with the Brazilian carrot having nematode resistance, it is also heat-tolerant, which is great news for us in California, especially with the rising temperatures.

It is said that California is getting closer and closer to getting its own commercial variety. “We’ve also found genes for resistance in other carrots from around the world, from Syria, China, Europe, and we intercrossed those also into California, so we’re putting a couple of genes in,” he said.

With all of these genes, this makes for an even stronger and durable resistance to nematodes.

New Nematicide Available

New Velum One Nematicide Registered For Use in California

By Patrick Cavanaugh, Farm News Director

Horticulture crops in California and Arizona can now be protected by Velum One nematicide, a wide-spectrum nematicide that increases root health and suppresses key diseases.

“We’re excited to see Velum One go to work for growers in the key horticultural areas of California and Arizona,” Bayer Product Manager Joel Lipsitch said. “It’s another example of the innovation that our growers have come to expect from Bayer.”

Velum One suppresses nematodes below ground but also works by moving upward from the roots into the leaves of the plant to suppress key diseases and promote early season crop establishment. This activity has been shown to protect roots and establish the crop by limiting damage from a wide range of nematodes and key diseases, such as powdery mildew.

Trials have shown that Velum One aids in increasing yields as it protects plants from nematodes and disease.

“In tomatoes, for example, we’re seeing significant yield increases both from Velum One versus untreated and more importantly when Velum is added to grower-standard programs” Lipsitch said. “The combination of nematode and disease control really gives growers confidence that they are maximizing their yields and return on investment.”

Velum One is applied early in the growing season via drip chemigation. While it’s not meant to replace a fumigant, Velum One is most effective when used as part of a complete nematode management program.

BREAKING NEWS: Historic Monterey County Farmworker Safety Initiative

BREAKING NEWS

Ag Commissioner & Farmworker Advisory Committee Announce Historic Pesticide Initiative for Farmworker Safety

 

Monterey County Agricultural Commissioner, Eric Lauritzen and the Farmworker Advisory Committee, formed with the assistance of the Center for Community Advocacy (CCA), announced an historic initiative TODAY aimed at providing additional pesticide protections for farmworker safety. The initiative launches a pilot program with leading growers to enhance worker notification through warning signs when pesticides are used in the fields.

 

“California has the toughest farm pesticide restrictions in the nation, and Monterey County already imposes local rules that further protect farmworkers,” said Lauritzen at TODAY’s press conference. “But we are going to do even more to communicate our commitment to safety in the fields.”

 

“We are excited about this initiative that adds an additional element of protection for farmworkers by providing the time and date when it is safe to reenter the fields that require posting,” said Lauritzen. “Farmworkers are the backbone of Monterey County’s $4.8 billion Ag industry, and they are entitled to the highest standard of pesticide safety.”

 

Eric Lauritzen, Monterey County Ag Commissioner

Eric Lauritzen, Monterey County Ag Commissioner, speaking at Press Conference TODAY on Historic Farmworker Safety Initiative

Intended to protect farmworkers, the initiate “has created a relationship between our office, the regulators and the farm worker community,” said Lauritzen. “And it’s really building trust and confidence with our office and the regulatory program there to protect farmworkers,” noted Lauritzen.

 

Additionally, every farmworker in Monterey County (approximately 50,000) will receive a business-card-sized information card (in Spanish) advising them to call the Agricultural Commissioner’s Office if they suspect violations of safety rules. The cards also advise employers that it is illegal to retaliate against farmworkers who seek the help of the Agricultural Commissioner’s Office.

 

The information card reads:

If you have questions or complaints on pesticides, the Monterey County Agricultural Commissioner’s Office will help.

The card includes phone numbers and advises workers that state law also protects them against retaliation if they report a pesticide problem.

 

Currently, regulations for posting pesticide warning signs do not require information indicating the date or time when it is safe for farmworkers to re-enter the fields. The pilot program will include the addition of one sign that will be prominently marked with a red flag and include the date and time that the law allows workers to safely reenter the field. Only the grower or his/her officially designated representative may remove the signs, after first showing the crew leader proof that the re-entry restrictions have expired.

 

Osvaldo Cisneros, a lettuce worker and member of the Farmworker Advisory Committee, feels that the change is very important. “Some farmworkers have been showing up for work and have been told by their mayordomos (supervisors) to re-enter fields even though warning signs are still up,” said Cisneros. “They have to depend on the word of the mayordomos even though they have no way to verify what they are told. This change will allow farmworkers, themselves, to tell when it is safe to enter fields.”

 

The posting and information card initiatives were developed in cooperation with the Farmworker Advisory Committee, a group formed jointly by Lauritzen and the non-profit Center for Community Advocacy. “Many farmworkers are unaware of their right to a safe working environment,” said CCA Executive Director Juan Uranga. “That’s why it is important to provide farmworkers with the information they need to both protect themselves and also gain access to the agencies, like the Monterey County Agricultural Commissioner’s Office, that exist to protect them.”

 

A second member of the Farmworker Advisory Committee, Maria Elena Andrade, added: “It is important for our community to know that the Agricultural Commissioner’s Office exists to serve us, as well as the other parts of the agricultural industry. We are trying to create that message through the Farmworker Advisory Committee, even as we work with the Ag Commissioner and his staff to improve safety for farmworkers.”

 

Growers involved with the initiative include Sea Mist Farms, Tanimura & Antle, Bayview Farms, Scheid Vineyards and Costa Family Farms. Lauritzen recognized these leading growers for their, support, innovation and dedication in their effort to provide additional protections for farmworkers.

 

Lauritzen briefed officials at the state Department of Pesticide Regulation (DPR) on the pilot warning sign program and the information card campaign. DPR Director Brian Leahy praised the Monterey County initiative. “We all know that farmworkers are the most vulnerable population in terms of potential exposure to pesticides,” said Leahy. “When we protect farmworkers more effectively, we also enhance protection for the environment and the community at large. This initiative represents an important step forward for farmworker safety, and it underscores California’s leadership in environmental protection.”


Historic Note:

The accord reached two years ago between the Office of the Monterey County Agricultural Commissioner, the agency that oversees pesticide regulations and other worker safety matters, and the Center for Community Advocacy (CCA), a farmworker advocacy group, established the Farmworker Advisory Committee for the Office of the Agricultural Commissioner of Monterey County—the first of its kind in the State Of California.

USDA Pesticide Data Program Report Confirms Food Safety

USDA Pesticide Data Program Report Confirms Food Safety:

More than 99 percent of sampled food tested below allowable pesticide residue levels!

The U.S. Department of Agriculture (USDA) has confirmed again in its annual report that American consumers can focus on the nutritional benefits of conventional and organic produce without concern for pesticide residues. Over 99 percent of fresh and processed food available to consumers tested below allowable pesticide residue levels, as detailed in the 24th Pesticide Data Program (PDP) Annual Report released on January 11, 2016 by the USDA Agricultural Marketing Service (AMS). Only .36 percent [0.36%] of the products sampled through the PDP had residues above the U.S. Environmental Protection Agency (EPA) established tolerances, giving consumers plentiful options to meet their daily nutritional needs.crop life america logo

“Today’s consumers can choose from food produced with a variety of farming methods and necessary crop protection strategies and be confident that it will sustain and enrich their families’ lives,” stated Jay Vroom, president and CEO of CropLife America (CLA). “Across the nation, our growers continue to use the most advanced crop protection technology available to target specific crop threats. From precision agriculture to integrated pest management, farmers in the heartland, the plains, coastal areas and everywhere in between are pushing forward with the best ways to produce food for their communities and for the country.”

PDP researchers tested a total of 10,619 samples of fresh and processed fruit and vegetables (8,582 samples), oats (314 samples), rice (314 samples), infant formula (1,055 samples), and salmon (354 samples). To ensure the samples were representative of the U.S., researchers collected data in a variety of states throughout different times of the year. The findings support the Dietary Guidelines for Americans 2015-2020, recently released by USDA and the U.S. Department of Health, which encourage consumers to eat more fruits and vegetables.ChooseMyPlate.gov

“With rapid advancements in computing technology, the space for developing new ways to fight agricultural threats is increasing exponentially,” stated Dr. Janet E. Collins, senior vice president of science and regulatory affairs at CLA. “Consumers have a number of options at the grocery store, thanks in large part to the work of the scientific community involved in research and development, the companies that are manufacturing products, and America’s farmers and ranchers. The 2014 PDP report demonstrates again that, with the sound science-based regulation of pesticides and commitment from the industry, farmers and other stakeholders, we can reach toward making sure that every American, no matter their wallet size or geographic location, can access healthy food.”

A 2012 report from CLA demonstrates that crop protection has made healthy food more financially accessible to the American consumer, providing a 47.92 percent savings in overall grocery bills for a family of four in the U.S.1 In addition, increased agricultural production, due to advanced pesticides, has created an additional 1,040,661 jobs generating more than $33 billion in wages—all while decreasing the need for tillage operations, thereby reducing fossil fuel use by 558 million gallons per year.

Recent reports from the United Nations also show that an increasing number of people worldwide have gained access to healthy food. Over the past 25 years, the number of people worldwide who are hungry has declined from one billion to about 795 million, or about one person out of nine—which means that 2 billion people have avoided a “likely state of hunger” given the global population increase of 1.9 billion people since 1990-92.2 Multiple factors have contributed to the decrease in global hunger, including the integration of family farmers and small holders in rural areas into well-functioning markets for food, inputs and labor.

The PDP was established in 1991 for the purpose of collecting data on pesticide residues found in food. Information collected by the PDP is sent to the EPA to help the agency conduct important dietary risk assessments. The USDA also uses this data in the development of integrated pest management objectives. Since the PDP program was initiated, 109 different commodities have undergone testing. A complete version of the 2014 Annual Summary is available at www.ams.usda.gov/pdp.

Winegrape Rootstock Trials

Winegrape Rootstock Trials for Pest Resistance and Vine Productivity

By Patrick Cavanaugh, Deputy Editor

Larry Bettiga, a viticulture farm advisor with UC Cooperative Extension, Monterey County, is working with county growers on winegrape rootstock trials to increase vine productivity.

“Several things have happened,” noted Bettiga,“we are replanting vineyards on former vineyard lands, where a build-up of soil pests already exists. Farmers used to grow a lot of beans and tomatoes in the Valley, so we’ve had a lot of root-knot nematode populations from past cropping patterns.”

“We’ve recently seen ring nematode populations developing at multiple vineyard sites,” Bettiga continued. “With the loss of more effective fumigants, and then the loss of post-plant-type nematicides, the use of nematode-resistant roots is becoming more critical to the success of replanting these vineyards. We have hopes that Andy Walker, a UC Davis viticulture professor and grape breeder, is going to supply us with some better options than we currently have.”

“We have a site where we are comparing five new rootstocks that were released from UC Davis with a number of our standard rootstocks. We are just starting that work, so obviously we have to look at them for several years to get a good feel for how those stalks will fit in comparison to what we are now using,” he noted.

European Farmland Under Pressure

European Farmland under Pressure Due to Regulation and Diversion

By Laurie Greene, Editor

Jose Gomez Carrasco, executive sales manager for AGQ Labs and Technological Services based in Oxnard, is in charge of covering a large area that includes the U.S., Mexico and Central America. Noting global concern regarding how farmland is being used, particularly European farmland, Carrasco said, “There’s a growing population of around 150,000 or 170,000 new mouths every day to feed.” Carrasco said agricultural production on land designated for agricultural use in every country, worldwide, is being diverted to bio-ethanol, or bio-mass, or different renewable energy use, so the availability of agricultural products for food is diminishing.

Carrasco stated this progression needs to be moving in the opposite direction, “especially because there are other issues that are making production more challenging, such as water scarcity, soil erosion and the use and price of agro-chemicals, inputs and fertilizers, all of which are being controlled and monitored more and more.”

“The regulation of crop protection materials is intended to help everyone in the food supply chain,” he continued, “all the way from the grower to the consumer; however, sometimes these regulations can be quite burdensome.”

“In some cases regulations are not for the benefit of all,” Carrasco explained; “just for some. So in markets such as the European Union where the [maximum threshold] number of molecules registered has diminished from 1,000 to 300 or 400 in the last decade, we’re finding a lot of this regulation comes from Germany.” Carrasco said they are leaving a lot of farmers with no agro-chemicals in their arsenal, especially in Spain, Portugal, and Greece, all in southern Europe.

MRLs and Crop Protection Materials are Improving but Complicated

MRLs and Crop Protection Materials are Improving but Complicated!

By Laurie Greene, Editor and Patrick Cavanaugh, Associate Editor

Rachel Kubiak, Environmental & Regulatory Affairs director with the Western Plant Health Association, based in Sacramento, commented that crop protection materials are improving. They target specific pests and they are set to maximum residue levels (MRL’s) when sold domestically or internationally. Yet, they are quite complicated.

“The materials are getting better,” Kubiak said, “but I would say that there is a large component that I don’t believe the activist community understands,” noted Kubiak.

Richard Cornett, director of communications for WPHA, blogged, “What most people are unaware of is that there is a highly integrated and multi-layered process of safety procedures to assure that pesticides are accessed for their safe use around humans and in the environment.”

U.S. EPA (a) scientifically reviews all pesticides for safety before registration, (b) involves EPA scientists at the Office of Pesticide Programs, the Department of Fish and Wildlife, as well as other departments, (c) guarantees that any pesticide used in the U.S. has been accessed and is safe and (d) applies tolerances only to produce grown in or imported into the United States.

In California, the Department of Pesticide Regulation (DPR) enforces EPA tolerances by sampling produce for pesticide residues from throughout the channels of trade, both domestic and imported, including wholesale and retail outlets, distribution centers, and farmers markets.

“There are complications in making those products available to our growers,” Kubiak said, “because so much of what we produce in California is exported to other countries, and this MRL issue complicates things.”

Foreign countries follow an international standard called CODEX Alimentarus which contains a list of pesticide MRLs. EPA tolerances and International Codex MRLs are not harmonized; residue on an imported commodity can trigger a no-tolerance-established assessment and removal by California DPR while being a legal residue in other countries.

“I think this is a large area in which we could do better. Educating those who don’t live in our world on the difficulties in bringing new products to market isn’t as simplistic as they like to make it seem,” said Kubiak.

IR-4 Update

IR-4 To Focus on New Strategic Plan

By Courtney Steward, Associate Editor

At a recent meeting, California Ag Today met up with Dan Kunkel, associate director of the IR-4 Project for The Food and International Program at Rutgers University in New Jersey.

IR-4 Project LogoSince 1963, the IR-4 Project has been a major resource for supplying pest management tools for specialty crop growers by developing research data to support EPA tolerances and labeled crop protection product uses. The main goal of the IR-4 program, according to Kunkel, is to help specialty crop growers in California, but with a new emphasis on crop exportation.

Commenting on this new strategic plan for the IR-4 program, Kunkel said, “We are going to be doing a lot of the same things, like residue work, efficacy testing and our biopesticide and ornamental programs. But we are taking a larger focus on international harmonization of the pesticide residue limits for our grower exporters so they can feel more confident that their commodities won’t have issues in foreign trade.

“Of course we submit crop protection registration to the EPA for our growers. But when the commodities go abroad, we also submit the data to CODEX, an international database with maximum residue limits (MRLs), a type of tolerance standard, for pesticides,” said Kunkel.

“We also share data with some of the U.S. commodity groups to submit to the Asian and European markets so our growers’ exports can meet these residue limits as well,” he said.

Crop Production Service’s Justin Dutra on Pest Control

Justin Dutra on Pest Control

Cal Ag Today recently caught up with Justin Dutra, a crop consultant in pest control for the Hanford branch of Crop Production Services (CPS) to discuss some of the crops he looks after, including, “row crops, dairy crops, cotton, nuts and tree crops.

CPS logo”The staff and management at CPS are focused on providing their customers with the products and services they need to grow the best crops possible,” said Dutra. “They do this by providing an extensive selection of herbicides, insecticides and fungicides that farmers need to keep their crops pest-free.” Dutra reported the  leaffooted bug is causing concern for a few growers in his region.

CPS conducts year-round research and training to order to stay up-to-date on crop protection products and provide their members with accurate information on their use, benefits and limitations. While his region has seen relatively low levels of the leaffooted bug, Dutra noted some other bugs that are worrying growers, such as, “leafhoppers on tomatoes and stink bugs.”

The problem with leafhoppers is they puncture the underside of plant leaves and extract much-needed nutrients. Their saliva can cause spotting or yellowing of the leaves and stunting or distortion of the plant. The bigger concern growers have is leafhoppers can also transmit disease. Commenting on the disease that has been most problematic for farmers, Dutra said, “Curly top used to be just a virus you would see every once in a while; now it can wipe out a field.” Dutra noted when they started realizing leafhoppers were becoming a problem two years ago, and again this year, “We are starting to treat for them, and they are beginning to die down now, but they are still there to be reckoned with.”

While the shortage of water has affected growers up and down the state, Dutra noted, “I’m on the East Side and the West Side, and there are more tomatoes coming in on the East Side because of water restrictions on the West Side.”

Nimitz Nematicide Now Registered In California Fruiting Vegetables

New Nematicide is A Game Changer for Vegetable Growers

ADAMA, a world leader in customer-focused agricultural solutions, announced today that NIMITZ nematicide received state registration in California for use on tomatoes, peppers, okra, eggplant, cucumbers, watermelons, cantaloupe and squash.

NIMITZ, a revolutionary product, delivers an unmatched combination of efficacy, simplicity and safety for control of plant-parasitic nematodes on commercial vegetables.

With its fast-acting and unique mode of action, NIMITZ raises industry standards. As a truer, more complete contact nematicide, it also fills a void in the absence of methyl bromide.

Power of simplicity

NIMITZ represents the first new chemical nematicide to be introduced in more than 20 years. The product’s label carries the least restrictive signal word – ‘Caution’.

In contrast to fumigant nematicides, NIMITZ simplifies nematode management by lessening complex handling practices and application restrictions. The result is no Fumigant Management Plans, no 24-hour field monitoring, no buffer zones, no re-entry interval (REI), no specialized equipment and minimal personal protective equipment (PPE).

“NIMITZ is a contact nematicide, not a fumigant,” says Herb Young, ADAMA brand leader. “And because of its residual activity, NIMITZ’s control of nematodes often exceeds the commercial standards. The distinct advantage over other nematicides is that it frees growers from complications, liabilities, and dangers associated with fumigants.”Nimitz Logo

A better solution

As a non-gas formulation, the active ingredient in NIMITZ is distributed through the soil and into contact with nematodes through irrigation or rainfall. Unlike older chemistries, there is no mandatory tarping or specialized machinery requirement. Applications may include broadcast or banding with mechanical incorporation or through drip-injection.

As a ‘true nematicide’, NIMITZ causes irreversible nematicidal activity which results in pest mortality within 48 hours of application, rather than temporary nematostatic (immobilizing) activity as seen with organophosphates and carbamate nematicides.

“NMITZ is lethal to nematodes. As a result, we see greatly improved root health all season which leads to yield enhancement,” says Young.

The US Environmental Protection Agency (EPA) wrote in the Federal Docket on July 24, 2014 that, “Fluensulfone (NIMITZ) represents a safer alternative for nematode control with a new mode of action and a much simpler and straightforward product label.”

A secondary crop tier has been submitted to the EPA for future registration on potatoes, strawberries, carrots, tobacco and turf.

As new tool for California vegetable growers, NIMITZ has the potential to bring safety and simplicity to the nematode control arena which is constantly under increasing regulatory pressure.
