Citrus Mutual Encouraged by Farm Bill

California Citrus Mutual Commends Congress for Action on 2018 Farm Bill

News Release

This week, the U.S. Senate and the House passed the Agriculture Improvement Act of 2018, commonly known as the 2018 Farm Bill, with overwhelming bipartisan support. This legislation will direct agricultural policy and authorize funding for key agricultural programs in the federal government for the next 5 years.

President Trump has the opportunity to enact the 2018 Farm Bill before the end of the year.

CCM President Joel Nelsen offers the following statement:

“California Citrus Mutual applauds the Farm Bill conferees and House and Senate Ag Committees for moving forward a bill that includes priority programs for specialty crop producers. Jeff Denham, Jim Costa, and Jimmy Panetta were crucial voices for California farmers on the House Ag Committee. Along with Representatives Julia Brownley, Ken Calvert, and David Valadao, the California Members were instrumental to securing funding for research, trade and market enhancement, and pest and disease prevention that will directly benefit California specialty crop producers.

“With support from Congressmen Kevin McCarthy and Devin Nunes and Senators Feinstein and Harris, key programs and funding for the U.S. citrus industry will continue in the next Farm Bill.

“The U.S. citrus industry will receive funding to continue priority research to identify a solution to Huanglongbing, a devastating plant disease that is threatening the sustainability of our domestic citrus industry. This is a significant win for U.S. citrus growers.

“On behalf of the California citrus industry, I thank the Congressmen and Congresswoman, our U.S. Senators, and our colleagues in the specialty crop industry who worked diligently over the past several months to create a bipartisan Farm Bill that provides crucial resources to ensure our farmers can continue providing nutritious produce to Americans and people around the world.”

The 2018 Farm Bill includes $25 million per year for 5 years starting in 2019 for research specific to the invasive insect Asian citrus psyllid and deadly plant disease Huanglongbing (HLB). This Emergency Citrus Disease Research and Development Trust Fund will build upon the program created in the Specialty Crop Research Initiative (SCRI) title in the 2014 Farm Bill and complements the $40 million per year program funded by California citrus growers to stop the spread of HLB.

The legislation also includes funding for the USDA Animal and Plant Health Inspection Service’s (APHIS) Plant Pest and Disease Management and Disaster Prevention Program and the National Clean Plant Network (NCPN). Additionally, funding will continue for the Technical Assistance for Specialty Crops (TASC) program, which helps growers overcome artificial trade barriers. TASC has been in operation for over fifteen years and was created to address sanitary and phytosanitary issues and technical barriers to trade that prohibit or threaten exports of U.S. specialty crops.

Farm Bill Deal a Big Win for U.S. Citrus Growers

Agreement Provides $25 Million for ACP and HLB

News Release

Recently, leading farm bill negotiators in the House and Senate announced that they have reached an “agreement in principle” signaling that a final deal will be made before the end of the year.

Included in the initial agreement is language providing $25 million per year for 5 years for research specific to the invasive insect Asian citrus psyllid and deadly plant disease Huanglongbing (HLB).

The Emergency Citrus Disease Research and Development Trust Fund will build upon the program created in the Specialty Crop Research Initiative (SCRI) title in the 2014 Farm Bill, which dedicated research funding for citrus.

“The trust fund language is a significant win for U.S. citrus growers,” California Citrus Mutual President Joel Nelsen said. “It’s critical for the future of our industry and the domestic citrus market that we continue to invest in research aimed to find a solution for HLB.”

The Farm Bill funding specific to HLB research complements the $40 million per year program funded by California citrus growers to stop the spread of HLB, which has been detected in over 900 backyard citrus trees in Southern California. In recent years, the state of California has dedicated funds to augment ACP and HLB control efforts in urban areas, including the rearing and release of millions of beneficial insects in backyard citrus trees.

Negotiators have also agreed to maintain funding for the USDA Animal and Plant Health Inspection Service’s (APHIS) Plant Pest and Disease Management and Disaster Prevention Program and the National Clean Plant Network (NCPN). Additionally, funding will continue for the Technical Assistance for Specialty Crops (TASC) program, which helps growers overcome artificial trade barriers.

“On behalf of the California citrus industry, I want to thank the lead farm bill negotiators in both houses for their commitment to passing a Farm Bill that includes this vital funding for the U.S. citrus industry and specialty crops,” Nelsen said.

The spread of Asian Citrus Psyllid (ACP) continues to be a looming threat for Central Valley citrus growers as it vectors Huanglongbing (HLB), a disease that destroys citrus trees. Greg Douhan, a University of California Cooperative Extension Tulare County citrus farm advisor reported to California Ag Today recently that, “There have been so many people onboard really working at this from multiple angles, and we’re in the eradication mode. We want to make sure the insect doesn’t get established in the San Joaquin Valley.”

“If one were to look at a map of ACP infestation in California [such as CDFA Quarantine Maps and California Citrus Pest & Disease Prevention Program Threat map], they may consider it to be endemic in the Los Angeles area. Rest assured that anytime ACP is found in a trap, the CDFA sprays everything in that area within 400 meters.”

Douhan said the Valley is on high alert to find ACP in traps. “

If researchers discover a cluster of finds in any particular area, we manage some spray programs and try to get all the growers to do a coordinated effort in order to try to combat it,” he said.

SaveOurCitrusIn addition, the SAVE OUR CITRUS app is a free USDA iPhone app to report and identify the four leading citrus diseases: citrus greening, citrus canker, citrus black spot and sweet orange scab. Report your symptoms, upload a photo, and citrus experts will respond.

So far, the practices have been working well.

“I think most of the growers are very well informed,” Douhan said, “and are taking this very seriously because it is this their livelihood.”

Citrus Research Meeting Focuses on Moving Plant Material

Industry Discusses Strategies in Fighting  Huanglongbing Disease

By Jessica Theisman, Associated Editor

Franco Bernardi, the interim president of the California Citrus Research Board based in Visalia, attended a recent citrus regulatory meeting in Denver, Colorado. He has sat on that board for 27 years and is helping out while a new president is searched for and named.

The CRB just turned 50 years old, and it is all about finding solutions to the trying issues of pests and diseases in California citrus. Bernardi said the meeting was comprehensive in regard to moving plant material between research labs around the country.California citrus

“It was a very good meeting and fortunately it had the right people in the room, which doesn’t always happen when you have a large meeting like that,” Bernardi said.

It is a very complicated subject, but with the regulators, researchers and plant breeders, it was a good meeting. These decisions are leading to allow genetic material to be moved from one state to the other.

A lot of this surrounds huanglongbing (HLB) genetic material which is causing concern, but Bernardi said there was a consensus on how to do it.

“The regulators are now going to have to put some teeth in the regulation,” he said.

Some regulations may even need to be changed. Many states have the same safeguards. One thing that came out of the meeting is some of these processes and protections of moving material from one place to the other are already in place.

No End in Sight for Stopping Huanglongbing Disease

Millions Spent to Fight Huanglongbing, with No Cure

By Mikenzi Meyers, Associate Editor

The California citrus industry—made up of 3,500 growers in Ventura, Riverside, and the San Joaquin Valley, and encompassing 70-75 packing houses—is an agricultural facet that continues to make California a fresh citrus powerhouse. Joel Nelsen, President and CEO of the California Citrus Mutual, spoke to California Ag Today recently on the industry-wide issue of Huanglongbing Disease—a deadly disease that has threatened the industry in every part of the state.

“For our industry, it’s a combination of enthusiasm, unity, frustration, and aggravation because we continue to fight the spread of the disease in Southern California.”

“We’re continually frustrated because science has not yet found a cure. We’ve given the scientific community an average of thirty to forty million dollars a year to find a cure for this disease.”

In a recent study done by the University of California, Riverside, economic outputs of the citrus industry is roughly $7 billion.

“It’s an economic engine for certain parts of this state. Lose it, and it’s not a positive alternative, that’s for sure,” Nelsen said.

IR-4 Program Trying to Help Florida Citrus Industry Due to HLB

IR-4 Researchers Control Material to Help Citrus Industy

By Patrick Cavanaugh, Editor

Jerry Barron, executive director of the IR-4 Project at Rutgers University in New Jersey spoke to California Ag Today recently about his program.

A major priority with the IR-4 Project is the prioritization of projects that need to be done to find crop protection products for crops such as citrus. Among the urgent challenges for citrus is the control of the Asian Citrus Psyllid (ACP) which vectors Huanglongbing (HLB)—a fatal disease to citrus. Barron spoke about the disease, which has devastated Florida citrus growers and all parts of the citrus economy in the state.

“HLB is devastating Florida citrus growers and the economy in Florida. It’s about a billion dollars of lost production, which is affecting local communities, food processors, and the people who are harvesting the fruit,” Barron said. “It is totally disrupting the whole economic base of certain areas.”

“So what we’re trying to do is work with the people in Florida, to provide them some tools, not only to control the Psyllid which transmits the disease but also provide them some tools to help control the disease once it’s infected the plant.

“At this point, it’s very difficult because certain crop protection products are just not available, but we’re trying to find these magic bullets to truly give them a solution for this devastating problem,” he said.

Study Forecasts Cost of Regulations on California Citrus Industry

Citrus Research Board Explains Cost Impacts on Growers

News Release From California Citrus Mutual

New regulations are expected to cost California citrus growers an average of $701 per acre per year, or $203 million annually statewide, according to a new study commissioned by the Citrus Research Board (CRB).

“Compliance with environmental regulations not associated with groundwater sustainability is estimated to increase costs by $17.7 million, or $67 per acre of citrus,” predicts Bruce A. Babcock, Ph.D., a professor in the School of Public Policy at UC Riverside who authored the study. “New labor requirements will increase costs by $112 million, or $357 per acre, once they are all phased in.”

“Babcock has presented a well-researched economic report that shows how new regulations will increasingly impact California’s citrus industry,” said CRB President Gary Schulz.

The report, Impact of Regulations on Production Costs and Competitiveness of the California Citrus Industry, also predicts that controlling the Asian citrus psyllid (ACP) “will increase costs by $65 million, or $248 per acre per year, if controls are extended to all citrus-growing regions.” Compliance training costs are estimated to increase costs by another $29 per acre, or $7.5 million for the state citrus industry.

“As I read and reread Dr. Babcock’s report, two things kept jumping off the page: one, ‘Cost increases borne by California’s citrus but not by … other citrus growing regions decrease the future competitiveness of California’s citrus industry’; and two, ‘… future compliance with these regulations is estimated to increase costs by $203 million, or $701 per acre per year,'” said California Citrus Mutual President Joel Nelsen. “When the cost of citrus at store level gets too expensive, consumers look for lower priced fruit. This UCR report paints a clear path for policy makers if their goal is to drive the citrus industry out of California and onto off-shore production areas.”

The 20-page report includes a breakdown of increases in labor costs, including California’s minimum hourly wage increases, which are scheduled to rise in annual increments to $15 over the next four years. The report also covers the projected cost increases of recent state legislation dealing with paid sick leave, payment rates for rest and recovery periods, overtime and workers compensation.

The section on insecticide treatment addresses grower cost of spraying for ACP, even though the severity of the problem currently differs greatly in various areas of the state. If ACP establishes itself in all citrus regions in the state, which the report says is “almost inevitable,” control efforts would amount to $39.5 million per year, according to Babcock. This would be in addition to the state-mandated tarping of fruit that is transported to packinghouses, at a cost of approximately $9 million per year.

According to the report, The Food Safety Modernization Act, which was passed in 2011 and is still being implemented, will not require major changes for growers who are already GFSI-certified (Global Food Safety Initiative compliant).

The impact of the Sustainable Groundwater Management Act (SGMA) is hard to predict, according to Babcock. “It will not be possible to calculate the impact of SGMA until each basin’s groundwater sustainability plans have been finalized,” he states. “Without new surface water supplies, it seems inevitable that some farmland that currently relies on groundwater will need to be fallowed to balance withdrawals with recharge rates.”

Babcock, a Fellow of the Agricultural and Applied Economics Association, has won numerous awards for his applied policy research. He received a Ph.D. in Agricultural and Resource Economics from UC Berkeley, and Master’s and Bachelor’s degrees from UC Davis.

The CRB administers the California Citrus Research Program, the grower-funded and grower-directed program established in 1968 under the California Marketing Act, as the mechanism enabling the state’s citrus producers to sponsor and support needed research.

Fighting Asian Citrus Psyllid On and Off the Farm

Fighting ACP on Farms and Residential Areas Critical

By Hannah Young, Associate Editor

Pests and diseases are as prominent as ever not only for California farmers but in residential areas as well. California Ag Today recently spoke with Rick Westcott, a senior sales rep for Bayer Crop Science, about preventative materials for pests and diseases and the importance of controlling the spread of those diseases, particularly Asian citrus psyllid.

Westcott explained that the advantage of Movento, a powerful insecticide, is that it is systemic, it’s applied early, and it will translocate throughout the entire tree.

“It’s both phloem and xylem movement, so it’ll go down into the roots and then back up so it constantly recirculates within the plant,” Westcott said. “That’s what gives it the longevity of control.”

In citrus trees, Movento typically takes about 65 to 70 days to start working after circulating through the plant which helps with the longevity of the product, Westcott added.

Although Movento is not used specifically for Asian citrus psyllid, it has proved to aid in controlling the pest.

Westcott said Movento is currently being used against citrus red scale and applied during pedal fall along with thrip sprays, which farmers are applying anyway.

“It will take care of your red scale, your early red scale spray, and of course, because it also controls Asian citrus psyllid, it’s a bonus to do that too,” Westcott said. “Then the other thing that they’re doing with the thrip spray as well for katydid control, which is also an issue in citrus at that thrip timing.”

By patrolling and monitoring for ACP, the spread of HLB can also be controlled.

“The key is to keep the ACP at the lowest level possible or zero if that’s possible. [The] fortunate thing for us in the San Joaquin Valley is the fact that we do a lot of spraying for other pests throughout the year that almost everything that we put in the tank happens to also control ACP at the same time,” Westcott explained.

Westcott said that this is the reason we have not seen a huge outbreak of ACP in the San Joaquin Valley, unlike other parts of California.

“The problem isn’t in any commercial grove at this point, but it’s all residential,” Westcott continued. “It’s all concentrated in the residential areas, so there are certain products that you can use an ag that you can’t use there, but most of them, fortunately, you know, they have a label for both residential and agriculture, so they do crossover to stop them there so they don’t get here.”

HLB is still posing a threat in California, but most specifically in the Los Angeles area.

“The total amount of trees currently that are infective with HLB in the counties of LA, Orange and Riverside County is 645. And then if you compare that from a year ago: a year ago, there were only 73 trees that they had infected, and it’s changing every day,” Westcott said.

Governor Brown Includes $12.5 Million In Budget for HLB Control

HLB Funds To Be Used by the Citrus Pest and Disease Prevention Program

News Release

Recognizing the importance of protecting California’s commercial citrus industry and backyard citrus trees, Governor Jerry Brown’s 2018-19 California state budget includes $12.5 million from the general fund dedicated to fighting an incurable citrus disease called Huanglongbing (HLB).

Signed last week, the funds will be used by the Citrus Pest & Disease Prevention Program (CPDPP), a program primarily funded by California citrus growers and administered by the California Department of Food and Agriculture. The CPDPP helps detect and eradicate Huanglongbing in residential areas, suppress Asian citrus psyllid populations, control the movement of the Asian citrus psyllid, enforce regulations, and fund outreach programs to homeowners, industry members and local governments.

While Governor Brown’s commitment to helping fight HLB is a step in the right direction, California citrus is at a crossroads. More than 685 cases of Huanglongbing have been detected in California, with more than 350 detections in 2018 alone, all in urban areas of Los Angeles, Orange and Riverside counties.
