BASF is donating $75,000 to Feeding America, the nation’s largest hunger-relief organization, to help feed struggling families and individuals throughout the U.S.

“Hunger is a very real problem for tens of millions of people in America, including low-income families and seniors,” said Scott Kay, Vice President, U.S. Crop Protection for BASF. “Through our contribution to Feeding America, we can help provide healthy fruits and vegetables to people and communities who may not have regular access to them. In many ways, this partnership is an extension of the work we do every day with growers to help them feed our hungry world population.”

The donation will support Feeding America’s National Produce Program, an initiative that helps with planning, transportation and logistics to ensure fresh produce deliveries to the 200 member food banks around the country.

The commitment from BASF will help Feeding America provide 675,000 pounds of produce to families and individuals in need. The donation includes $5,000 in contributions from BASF grower customers who chose to be part of this donation.

“BASF was a natural fit to partner with Feeding America as we continue to focus on providing more nutritious fruits and vegetables for the clients we serve,” said Nancy Curby, vice president of corporate partnerships for Feeding America. “Their support will help extend the reach of our National Produce Program and help more Americans in need.”

Employees at the Research Triangle Park, North Carolina, BASF headquarters also raised more than $18,000 for the Food Bank of Central & Eastern North Carolina through a virtual food drive and a special showing of the movie “Farmland.” The BASF Crop Protection division is also sponsoring the local ABC network affiliate WTVD’s “Heart of Carolina” food drive during the holiday season to collect food and raise money for the Food Bank of Central & Eastern North Carolina and the Second Harvest Food Bank.

“Our business and our employees are very pleased to partner with the many dedicated food bank volunteers who share our commitment to feeding those facing hunger, not only during the holidays, but all year long,” Kay said.

 

BASF’s Crop Protection division provides innovative solutions in crop protection, seed treatment and biological control as well as solutions to manage water, nutrients, plant stress, pest control and public health. The Crop Protection division supports growers to optimize agricultural production, improve their business efficiency and enhance the quality of life for a growing world population.

Collaboration Among Government Agencies and CA Rice Commission Germinates in Win-Win Policy

Collaboration Results in Win-Win Endangered Fish/Safe Thiobencarb Use Policy

By Laurie Greene, CalAgToday Editor and Reporter

Roberta Firoved, Industry Affairs Manager for the California Rice Commission

Roberta Firoved, Industry Affairs Manager for the California Rice Commission

Roberta Firoved, Industry Affairs Manager for the California Rice Commission, stated in a press release Wednesday, “A great example of our positive relationship with the U.S. Environmental Protection Agency (U.S. EPA) is found in the recent press release, ‘U.S. EPA, federal and state agencies, rice growers, industry act to protect endangered salmon and steelhead trout in California.’”

In the release, Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest, states, “Working closely with our state and federal partners, our joint efforts will protect salmon and steelhead trout while maintaining rice production in California. This action also supports EPA’s commitment to minimize pesticide pollution in the San Francisco Bay Delta.”

“This is a smart approach to pesticide use that includes important safeguards for protected fish while still allowing growers to care for their crops,” said Will Stelle, administrator of National Oceanic and Atmospheric Administration (NOAA Fisheries) West Coast Region, in the same release. “This demonstrates that we can find balanced and workable solutions through collaboration.”

The California Department of Pesticide Regulation (CDPR) established measures to protect salmon and steelhead trout based on proximity to endangered and threatened species habitat according to NOAA Fisheries geographic locations, as well as information and best management practices from the California Rice Commission and its grower members, plus the California Regional Water Quality Control Board – Central Valley Region. U.S. EPA and Valent, the manufacturer of the herbicide thiobencarb, also worked to put these restrictions in place.

After reviewing CDPR’s data on pesticide use and the state’s protective measures to be enforced by County Agriculture Commissioners, NOAA Fisheries found that thiobencarb use on rice in California would not jeopardize salmon and steelhead trout provided protective measures currently being applied in California are ensured.

“The positive approach we applied throughout development of the thiobencarb use conditions,” Firoved explained, “expanded into our interaction with the NOAA National Marine Fisheries Services (NMFS) as they researched and wrote the biological opinion (BiOp) for thiobencarb.”

Thiobencarb is a systemic, pre-emergence herbicide in liquid or a granular formulation that inhibits shoots of emerging weed seedlings. First registered for use on rice in 1982, thiobencarb is used to control grasses, sedge and broadleaf weeds in food crops such s rice (represents 95% of use), lettuce, celery, and endive. Thiobencarb, or Valent’s Bolero® UltraMax Herbicide, may be applied using ground spray equipment or by aircraft.

“The win for rice growers is that the farming practices developed over time are also protective of endangered species. We always assumed this to be the case, and entrusted the thiobencarb BiOp for confirmation.

Reflecting on the successful collaboration, Firoved stated, “We have no magic bullet, nor do we approach the issues with contention. Our perspective is that all participants around the table are looking for the same end result, no matter where they work.”

USDA Disaster Assistance to Help Thousands of Honeybee, Livestock and Farm-Raised Fish Producers

The USDA announced that nearly 2,500 applicants will receive disaster assistance through the Emergency Assistance for Livestock, Honeybees, and Farm-Raised Fish Program (ELAP) for losses suffered from October 1, 2011, through September  30, 2013.

The program, re-authorized by the 2014 Farm Bill, provides disaster relief to livestock, honeybee, and farm-raised fish producers not covered by other agricultural disaster assistance programs. Eligible losses may include excessive heat or winds, flooding, blizzards, hail, wildfires, lightning strikes, volcanic eruptions, and diseases, or in the case of honeybees, losses due to colony collapse disorder. Beekeepers, most of whom suffered honeybee colony losses, represent more than half of ELAP recipients.

“As promised, we’re making sure that thousands of producers who suffered through two and a half difficult years without Farm Bill assistance, are getting some relief,” said Agriculture Secretary Tom Vilsack. “Once the Farm Bill was restored, not only did we implement the disaster assistance programs in record time, we’re issuing payments less than three months after the enrollment deadline. The funds will hopefully help producers with some of the financial losses they sustained during that time.”

The Farm Bill caps ELAP disaster funding at $20 million per federal fiscal year. To accommodate the number of requests, which exceeded funds available for each of the affected years, payments will be reduced to ensure that all eligible applicants receive a prorated share of assistance.

ELAP was made possible through the 2014 Farm Bill, which builds on historic economic gains in rural America over the past five years, while achieving meaningful reform and billions of dollars in savings for the taxpayer. Since enactment, USDA has made significant progress to implement each provision of this critical legislation, including providing disaster relief to farmers and ranchers; strengthening risk management tools; expanding access to rural credit; funding critical research; establishing innovative public-private conservation partnerships; developing new markets for rural-made products; and investing in infrastructure, housing and community facilities to help improve quality of life in rural America.

NEW TULARE COUNTY ASIAN CITRUS PSYLLID DETECTIONS NEAR EXETER  

BREAKING NEWS 

 

The Tulare County Agricultural Commissioner’s office announced TODAY that one additional Asian Citrus Psyllid (ACP) has been detected on a trap south of the city of Exeter. The latest interception was confirmed by the California Department of Agriculture (CDFA). Maps and current information are available on the Agricultural Commissioner’s website by visiting: http://agcomm.co.tulare.ca.us/default/.

CDFA has already begun to saturate the affected area with detection traps in order to determine the extent of any infestation.The United States Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) and CDFA will work collaboratively to determine what steps are taken next.

The Asian citrus psyllid is an invasive species of grave concern because it can carry the disease Huanglongbing (HLB), also known as citrus greening. All citrus and closely related species are susceptible hosts for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health, producing bitter, misshaped fruit until it dies. To date, HLB has been detected on just one residential property in the Hacienda Heights neighborhood of Los Angeles.

“Our staff will continue to support the efforts of our $750 million citrus industry, as well as our residential citrus owners,” said Tulare County Ag Commissioner Marilyn Kinoshita. “I want to emphasize that citrus fruit is safe to eat and the disease is not harmful to human health.”

Residents in the area who think they may have seen the pest are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or the Tulare County Agricultural Commissioner at (559) 684-3350. Media inquiries related to technical questions about Asian Citrus Psyllid and Huanglongbing disease are encouraged to contact Katie Rowland, Account Coordinator for Nuffer, Smith, Tucker Inc. at (661) 817-3638.

BREAKING NEWS: Two New ACPs Found in One Trap Near Exeter

CDFA Has Saturated Exeter Area with Extra ACP Detection Traps

The Tulare County Agricultural Commissioner’s offices announed TODAY that two additional Asian citrus psyllids (ACP) have been detected on one trap south of the city of Exeter. The latest interceptions were confirmed by the California Department of Food and Agriculture (CDFA). Maps and current information are available on the Tulare County Agricultural Commissioner’s website.

CDFA has already begun to saturate the affected areas with detection traps in order to determine the extent of any infestation.The United States Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) and CDFA will work collaboratively to determine what steps are taken next.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species are susceptible hosts  for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health,producing bitter, misshaped fruit untilitdies. To date, HLB has been detected on just one residential property in the Hacienda Heights neighborhood of Los Angeles.

Tulare County Ag Commissioner Marilyn Kinoshita said that her staff will continue to support the efforts of our $750 million citrus industry, as well as our residential citrus owners. “I want to emphasize that citrus fruit is safe to eat and the disease is not harmful to human health,” said Kinoshita.

Residents in the area who think they may have seen ACPs are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or the Tulare County Agricultural Commissioner.

Media inquiries related to technical questions about Asian citrus psyllid and Huanglongbing (HLB) disease are encouraged to contact Katie Rowland, Account Coordinator for Nuffer, Smith, Tucker Inc. at (661) 817-3638.

The best way to fight HLB is to suppress the spread of ACPs which can carry it. So, California Citrus Research Board hired Nuffer, Smith, Tucker, (NST) a public relations firm, to raise awareness of ACPs and HLB, especially among the many California homeowners with backyard citrus trees who may unknowingly be harboring the pest, and to encourage the public to take necessary steps to save California citrus.

SURPRISE: EWG recommends Fruits & Vegetables – Conventional or Organic

EWG to Continue Publishing  “Dirty Dozen” List of Conventional Produce

By Laurie Greene; CalAgToday Editor, Reporter

This week, Marilyn Dolan, the Executive Director of the Alliance For Food and Farming[1] (AFF) sent a letter to Environmental Working Group[2] (EWG) President Ken Cook requesting they discontinue their annual release of the so-called “dirty dozen” list. Scott Faber, EWG’s Vice President of Government Affairs responded online TODAY that “EWG’s top shelf advice is to eat your fruits and veggies. But, as EWG’s research shows, not all veggies are the same, and some have more pesticide residues than others. That’s why we will ignore the call to discontinue publishing our Shopper’s Guide.”Food Scoring Factors

This correspondence comes following EWG’s statement that organic and conventional produce are best foods for consumers and that organization’s new and strongly worded recommendation about the need for increased consumption of all fruits and vegetables – whether they are organically or conventionally grown. The statement accompanied the release of EWG’s Food Scores: Rate Your Plate, an easy-to-use food database and mobile app on October 27, 2014 that rates and shares information for more than 80,000 foods from about 1,500 brands in a simple, searchable, online format. “The new database is the most comprehensive food-rating database available to consumers,” EWG said in a statement. “Its scoring system factors in not only nutrition, but also ingredients of concern, such as food additives, and contaminants. It also estimates the degree to which foods have been processed.”

Each year, EWG publishes Shopper’s Guide To Pesticides In Produce “to help consumers find conventional fruits and vegetables with low concentrations of pesticide residues,” explained Sonya Lunder, EWG’s senior analyst and principle author of the report.  “If a particular item is likely to be high in pesticides, people can go for organic.”

While the annual Shopper’s Guide features a “Clean Fifteen” section of conventional produce with the least amount of pesticide residues, it is famous for its annual “Dirty Dozen” list of the most pesticide-contaminated produce and its Dirty Dozen™ Plus” highlights hot peppers and leafy greens – kale and collard greens – often tainted with unusually hazardous pesticides. The Alliance for Food and Fiber has worked hard to debunk the dirty dozen list,” said Dolan, “with good scientific evidence that even though produce may have crop protection product residues on a small percentage of the total volume of produce, the residue is far less than FDA standards.”

Here is the letter from AFF to EWG, in its entirety.

Mr. Cook:AFF

We noted your organization’s acknowledgment in the “Food Scores” database that both conventional and organic fruits and vegetables should be considered best food choices for consumers.  We also saw the Environmental Working Group’s new and very strong statement concerning the need to increase daily produce consumption for most Americans now posted on your website. 

As you are well aware, our organization, the Alliance for Food and Farming (AFF), has repeatedly requested that you discontinue the publication of your annual “dirty dozen” list because it is misleading to consumers, is not peer-reviewed and is not based on real risk.  The conventional and organic fruit and vegetable farmers we represent produce a very safe product that experts around the world agree we should all be eating more of for better health.  In addition, the USDA, FDA and EPA all clearly state that residues do not pose a food safety concern.

For these reasons, along with EWG’s new and strong acknowledgement of the health and safety of conventional produce, the AFF renews its call for your organization to end your annual release of the “dirty dozen” list.

While there is still much information to come with respect to the validity and credibility of your new “Food Scores” report, we are pleased to see that, for produce, this new report supports decades of nutritional studies showing the health benefits of a diet rich in fruits and vegetables – regardless of whether they are organic or conventional. We are sure you would agree that it is illogical for your organization to urge consumers to eat more conventional produce while simultaneously mislabeling these safe and healthy foods “dirty,” “toxic laden,” and “contaminated” among other things.

Therefore we ask you to stop unfairly disparaging conventionally grown fruits and vegetables with your annual “dirty dozen” list release.  Instead, please continue on the positive path you’ve established with your new statement urging increased consumption. That is the right message for consumers and also meets your organization’s stated objective to “empower people to live healthier lives.”

We look forward to hearing from you regarding your future intentions for the so-called “dirty dozen” list.

Sincerely,

Marilyn Dolan, Executive Director, Alliance for Food and Farming

 

Here is the Scott Faber, EWG’s Vice President of Government Affairs’s response to AFF TODAY in its entirety:

Food industry lobbyists are none too pleased with EWG’s new scoring system for foods, accusing EWG’s Food Scores of:

         “Misinformation”

EWG

         “Void of scientific rigor”

         “Inaccurate and misleading information”

         “Extreme and scientifically unfounded views”

Seems like we hit a nerve.

Apparently, helping consumers identify those foods with too much fat, sugar and salt  — as well as foods with unregulated food chemicals or too much mercury – is giving Big Food’s hired guns indigestion.

Of course, food manufacturers don’t like scoring systems like NuVal or Guiding Stars, so it’s no surprise they are already attacking Food Scores.

Could it be that so many packaged foods score poorly?

Here’s what we found: far too many packaged foods have too much sugar, salt and fat and many foods contain chemicals or other ingredients of concern.  Overall, 25 percent of the 80,000 products we reviewed received and 8, 9 or 10. (For EWG, less is more: the best foods score a 1, while the worst foods score a 10.)  

Big Food’s lobbyists contend that we relied upon “isolated studies” to include added sugars and some low-calorie sweeteners in our scores. By “isolated studies,” they mean peer-reviewed research by the Institute of Medicine, the health arm of the National Academy of Sciences.

Big Food’s lobbyists also claim that we used “online sources” to address the risks posed by arsenic and other food contaminants. By  “online sources,” they mean the Food and Drug Administration.

In fact, our scoring system is based upon hundreds of studies conducted by leading experts, including those at the World Health Organization. And, unlike industry-funded studies of food chemicals, the studies that served as our references are available for everyone to see.

Big Food’s lobbyists are especially peeved that EWG recognized that organic foods score better than conventional foods.

Well, duh. Unlike so-called “natural” foods peddled by food giants, certified organic foods cannot be produced with toxic pesticides, antibiotics and hormones. The U.S. Department of Agriculture has even stricter rules when it comes to what can go into “flavors.”  Nor can organic food use genetically engineered ingredients, though GE content doesn’t factor into our scoring system.

Even fruit and vegetable lobbyists took time to bash EWG’s new food scoring tool.  Top scores for actual fruits and vegetables weren’t enough for the Alliance for Food and Farming, a trade association that represents conventional produce growers, which accused EWG of making “disparaging, inaccurate safety claims” in our Shopper’s Guide to Pesticides in Produce. This is the same group that blamed EWG for scaring people away from healthy food and spent $180,000 of your tax dollars erroneously claiming the Shopper’s Guide discourages people from eating their fruits and veggies.

As regular users of the Shopper’s Guide know, EWG’s  top shelf advice is to eat your fruits and veggies. But, as EWG’s research shows, not all veggies are the same, and some have more pesticide residues than others. That’s why we will ignore the call to discontinue publishing our Shopper’s Guide.

It seems that some food and farm lobbyists can’t handle the food truth.

Research Targeting the ACP Olfactory System Shows Promise

A University of California Riverside Asian citrus psyllid (ACP) research team, led by Anandasankar Ray, associate professor of entomology, has found a new tool that targets the ACP olfactory system.  The ACP olfactory system is sensitive to a variety of odorants (odor molecules) released by citrus plants; in fact the ACP depends on its sense of smell to identify its citrus hosts, and this discovery offers an opportunity to develop new attractants and repellents, according to Ray.

Anandasankar Ray, UC Riverside Associate Professor of Entomology

Anandasankar Ray, UC Riverside Associate Professor of Entomology

As reported in Entomology Today, Ray’s research has identified a blend of odorants found in nature, including myrcene, ethyl butyrate and p-cymen, that can lure ACPs to sticky traps. In the study, odor-based traps caught nearly 230 percent more ACPs than conventional traps placed on the same trees.  “What’s particularly encouraging is that these three chemicals are affordable, useful in small quantities, and safe for human handling,” said Ray, with the potential of being developed into monitoring, masking and surveillance tools.

“We anticipate that this odor-based insect lure could be of use to growers in California and other parts of the world where ACP invasion is occurring,” Ray commented. “Our study also reports identification of odors that block the ACP olfactory system from detecting citrus odors and have potential for development into repellents.”

“Similar approaches can be taken to develop control strategies using odors for other insect pests of crops as well,” Ray explained.  UCR has great strengths in insect chemosensory research ranging from chemical ecology to olfactory and gustatory neurobiology of behavior. With expertise ranging from very basic science to applied areas, several UCR collaborating laboratories are working to find ways to control insects that transmit diseases like West Nile virus and malaria, in addition to citrus greening disease. UCR discoveries have the potential to bring about a paradigm shift in controlling these diseases. 

Study results on the lures were published in PLOS ONE, and the large-scale identification of odors detected by ACP was published in Chemical Senses.

ACP Quarantine in San Joaquin County, Guidelines and Scholarship

Expanded ACP Quarantine

Two portions of San Joaquin County have been placed under Asian citrus psyllid (ACP) quarantine following detections of one ACP within the City of Manteca and one within the City of Lodi. The quarantine zone in Manteca measures 105 square miles and in Lodi it measures 95 square miles.

The quarantine prohibits the movement of citrus and curry tree nursery stock out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures that are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.

The ACP, a tiny (0.125 in. length) mottled brown insect that is about the size of an aphid, is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species such as curry trees are susceptible, and there is no cure. Once infected, a diseased tree will decline in health with yellowing shoots, asymmetrical leaf mottling and abnormally shaped bitter fruit until it dies—typically within three years.  HLB was detected once in California, in 2012, on a residential property in Hacienda Heights, Los Angeles County.  This plant disease does not affect human health.

Residents in the area who think they may have seen ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899.  For more information on the ACP and HLB, please visit: www.cdfa.ca.gov/go/acp

ACP Effective Treatments

The University of California Agriculture and Natural Resources’ Integrated Pest Management (IPM) Program  has developed treatment guidelines for citrus growers within the quarantine zones. A general principle when applying insecticides to control ACPs in commercial citrus is that no one insecticide fully controls ACP across all life stages because:

  • All stages are difficult to contact with insecticides; eggs and nymphs are tucked inside new foliage and adults can fly.
  • Some insecticides show better efficacy against one stage over another.
  • Because systemic neonicotinoid insecticides require root activity for uptake, they are best applied during June through September.

The UC IPM Guidelines for Citrus provides a ranked list of insecticides that are effective against the Asian citrus psyllid with the pesticides having the greatest IPM value listed first—the most effective and least harmful to natural enemies, honeybees, and the environment are at the top of the table.

According to Mark Hoddle, UC Riverside (UCR) Director, Center for Invasive Species Research, “The science of biological control, the use of a pest’s natural enemies to suppress its populations to less damaging densities,” shows promise against the ACP with releases over the last three years of Tamarixia radiata–a parasitic wasp from Pakistan–in urban areas of southern California Thus far, this natural ACP enemy helps to control ACP growth in residential areas, but is inadequate for commercial application.

Climate Change Affects Integrated Pest Management Practices

Despite Lack of Funding, IPM Programs Need to be Re-Worked

By Colby Tibbet, California Ag Today Reporter

Climate Change is a pressing concern for growers and others in the ag industry, prompting the modification and redesign of Integrated Pest Management (IPM) practices, among other farming operations.

John Trumble, an entomology professor at the University of California, Riverside, explained that we are going have to change our IPM programs—processes based on scientific research for solving pest problems while minimizing risks to people and the environment. “We will have to account for changes in temperature, insects infesting fields more quickly, bio-controls including beneficial insects becoming possibly less effective, and altered plant growth due to elevated CO2 in the atmosphere.

Trumble noted,“What worked for your father isn’t going to work for us now. In the last 10 to 15 years, we’ve seen major changes in which insects are present, speed of entry into the fields, the extent of damage they cause and the plant’s lack of compensation for that damage. That is a lot of work for somebody in the future to redo all those IPM programs developed in the 60’s, 70’s, and 80’s, that we’ve used successfully for years.”

“One of our biggest problems in re-working these IPM strategies is that there’s a general move afoot in the government to reduce funding: for the USDA, the EPA, and even the National Institutes of Health. This year the USDA funded only 5 percent of the grants submitted,” said Trumble, “versus the normal 10-15 percent, and the funding shortage could halt investment in future programs. In a bad year, USDA would invest 12 percent—but five percent, who’s going to go into agriculture if you can only get five out of 100 grants actually funded? It’s really awful,” Trumble remarked.
