Gary Schulz Gives California Citrus ACP and HLB Update

California Citrus ACP and HLB Update from Gary Schulz

By Brian German, Associate Broadcaster

The Citrus Research Board (CRB) recently held their annual California Citrus Conference in Exeter, bringing together a variety of guest speakers and research presentations. The Conference focused on pressing Asian Citrus Psyllid (ACP) and Huanglongbing (HLB) issues, along with political action updates and current projects that are important to the citrus industry. Gary Schulz, president of the CRB, said “We have a 21-member board and we’ve been planning this event for the last 12 months. It’s been 4 years since we held the last conference,” noted Schulz.

The CRB is responsible for overseeing the California Citrus Research Program (CCRP), a grower-funded and grower-directed program created in 1968 under the California Marketing Act. The CCRP’s purpose to enable California’s citrus producers to sponsor and support research that furthers the overall industry. Therefore, close to 70 percent of the CRB’s overall budget is allocated to research.

Schulz said the Conference “was a great, great day to have a good update on some of the dollars the Citrus Research Board has been spending on the growers’ behalf on research.” Schulz explained HLB represents the single greatest threat that citrus growers have faced worldwide.

For the past seven years, the USDA and Congress have allocated between $10 and $12 million dollars annually for ACP and HLB research operations. Advocacy groups and other supportive ag organizations have contributed the difference to reach an annual ACP and HLB research budget of close to $90 million dollars a year. We fund a lot of UC Riverside and USDA agricultural research, service researchers, plus research at UC Davis and the University of Arizona,” Schulz noted.

Schulz, who has many years of experience in California agriculture, having served as general manager of the Raisin Administrative Committee and CEO of the California Raisin Marketing Board, stated that CRB has a great working relationship with California Citrus Mutual (CCM). “Joel Nelson and CCM have worked very hard with the packers to assess themselves, put together a private foundation, and work with the university,” Schulz said.

Interesting Forecast: Wetter Winter, with Possible Deep Frost?

Weather Pattern in California Could Hurt Citrus, Predictions Say

By Patrick Cavanaugh, Farm News Director

Some meteorologists are seeing evidence of weather data on the North Pole that could point to more rain and snow this winter. However it could come with several freeze events, which could hurt crops, especially citrus.

The Global Forecast Center is a group of meteorologists in Northern Idaho that conducts weather forecasting for agricultural interests throughout Florida, California and portions of Texas. In fact, they work closely with California Citrus Mutual.

Tom Dunklee, president and chief atmospheric scientist, Global Forecast Center and its associated “WeatherWatch” service, said, “What we see in our frost outlook is a cold year coming up and a bit of an increase in rainfall, which will make everybody happy. But we may have to pay the price with some very cold temperatures following these fronts.”

“The rains may be more frequent, but they will not be real big rain producers. They won’t be like El Niño years, where you get an inch and a half of rain or more. They will be cold, wet weather systems that come through, one half inch of rain at a time, followed by a possibility of frost,” Dunklee said.

Dunklee predicts the rain events may be followed by some dry weather for three or four days, then by another front coming through, doing the same thing. “What we are seeing is the type of weather pattern we saw in the late 1960s. It’s been quite a while since we’ve had one of these years shape up,” he said.

“I don’t think we are going to have a “Miracle March.” Instead, we are going to have a warm and drier than average spring. Most of the moisture is going to come in December, January and February, comprising those frequent frontal systems. Most of them will be followed by cool air and showery weather. Then the weather will dry out for three or four days, and the wet weather will return.”

Dunklee spoke of the intrusions of the cold arctic air that could arrive. “We think the intrusions will be from the North and Northeast—from Montana coming down through Nevada, then through the San Joaquin river drainage bringing quite a bit of cold air filtering into the [Central] Valley, and we’ll get the possibility of a hard frost, and maybe a freeze sometime in late December,” Dunklee said.

Dunklee also spoke about an increase in snowpack. “At the 7,000 foot level this year we may see higher than average, about 120% to 130% of average snow fall. It will be on the average of about six or seven feet. It may not actually get that deep at one time, but the potential is there for that,” he said.

“Most of the time it’s going to be about two, three feet of snowfall during the real cold months. Then in the spring it will melt fairly quickly, but it potentially is going to be a good snow pack, a little bit higher than average,” Dunklee said.

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.

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?

Nov 9 Annual Ag Awards Luncheon Honors Manuel Cunha, Booth Ranches

Manuel Cunha, Agriculturist of the Year

By Laurie Greene, Editor

On Wednesday afternoon, November 9, the Who’s Who of Agriculture will gather at the long-standing celebratory Annual Ag Awards Luncheon in Valdez Hall at the Fresno Convention Center to commemorate the achievements of an individual and a company in the County’s agricultural industry.

Nathan Ahle, president and CEO of the Fresno Chamber of Commerce, said, “We are very excited about this. This is the 33rd time the Fresno Chamber has presented the Agriculturist of the Year Award, and the 21st time the Fresno-based CPA firm Baker, Peterson and Franklin has presented the Ag Business of the Year Award. We recognize that Ag is really the life-blood of our economy. This event is an honor to do and something we take great pride in.”

This year’s Agriculturist of the Year Award recipient is Manuel Cunha, president of the Fresno-based Nisei Farmers League. “Everybody knows Manuel Cunha—a legend in Valley Ag as president of the Nisei Farmers League for two decades,” Ahle said. “ This gentleman is a force to be recognized with when it comes to fighting for our farmers, fighting for water, fighting for anything and everything that has to do with agriculture in the Central Valley.”

2016 Fresno Chamber of Commerce Agriculturist of the Year recipient, Manuel Cunha, president, Nisei Farmers League.

Nisei Farmers League, established in 1971, informs grower members about ever-changing regulations and policies and provides legal assistance for labor and workplace-related issues. The league’s leadership and staff maintain a close working relationship with local, state and federal agencies and legislators to assure grower interests are adequately understood and defended.

The League also collaborates with other grower and agricultural organizations in California and other states to help provide a powerful and unified voice for the agricultural community. The Nisei Farmers League is all about strength, clear focus and growers looking out for growers and farmworkers.

This year’s Ag Business Award recipient, Booth Ranches, is a premium San Joaquin Valley citrus grower. Otis Booth, Jr. founded Booth Ranches in 1957 on 40 acres by the foothills of the Sierra Nevada Range near Orange Cove.

Today, Booth Ranches is still family owned and operated on acreage from Orange Cove in the Northern San Joaquin Valley to Maricopa in Kern County to the South. Pasadena-born, fifth-generation farmer Loren Booth currently manages Booth Ranches which boasts premium Navel oranges, Valencia oranges, Cara-Caras, Minneolas and W. Murcott Mandarins that are distributed worldwide.

The selection panel went through a tough selection process, according to Ahle. “Those who have been in the Valley longer than I have tell me this is the strongest group of candidates for the award that we have ever had. I think it just speaks to the great passion that we have for Ag in this community, and Manuel Cunha and the team at Booth Ranches are great, great recipients.”

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.”

#CitrusMatters

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 (Source: 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.

The 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.

In 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.”

Breaking News: Cal Poly Opens New Greenhouse and Insect Rearing Facility

New Greenhouse Facility Opens to Save Citrus from Psyllids that Vector HLB

Facility to Rear Tamarixia Radiata, Natural ACP Predator

By Patrick Cavanaugh, Farm News Director

Scores of citrus industry leaders, citrus growers, scientists and CDFA officials attended the ribbon cutting event TODAY at the opening of a new greenhouse on the Cal Poly Pomona campus to rear Tamarixia radiata, a tiny parasitic wasp imported from Pakistan because it is an Asian Citrus Psyllid (ACP) nymph predator. ACP, in turn, is a serious nonnative citrus pest that can vector Huanglongbing (HLB)—a deadly citrus disease also known as Citrus Greening—that has devastated the powerhouse citrus

industry in Florida, threatens to ruin additional citrus economies, and is the biggest threat the California citrus industry has ever faced.

According to the United States Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS), infected citrus trees “produce fruits that are green, misshapen and bitter, unsuitable for sale as fresh fruit or for juice. Most infected trees die within a few years.” ACPs have been detected in Alabama, American Samoa, Arizona, California, Florida, Georgia, Guam, Hawaii, Louisiana, Mississippi, Northern Mariana Islands, Puerto Rico, South Carolina, Texas and the U.S. Virgin Islands. Of those locations, the HLB disease has been detected in California, Florida, Georgia, Louisiana, Puerto Rico, South Carolina, Texas and the U.S. Virgin Islands.

ENTER: Tamarixia radiata

Use of the ACP predator, Tamarixia radiata as a biological control for ACP was discovered by Mark Hoddle, biological control specialist and principal investigator, UC Riverside ( UCR), Department of Entomology. The first release of Tamarixia was in December 2011 after USDA-APHIS cleared the natural enemy for release from the Quarantine Facility at UCR.

Mark Hoddle UC Riverside Department of Entomology

“Tamarixia can kill ACP nymphs in two different ways,” explained Nick Hill, a Tulare County citrus producer and Citrus Pest & Disease Prevention Program (CPDPC) chair. “The first is parasitism. In this instance, a female parasitoid lays an egg underneath a fourth or fifth instar—the larger and final developmental stage of the ACP nymph before becoming an adult—nymphs that are most preferred by Tamarixia for parasitism. When the egg hatches, the Tamarixia larva begins to feed on the under-surface of the ACP nymph. Eventually the larva completely excavates the body cavity of the ACP nymph and pupates inside the empty shell of its host.”

Hill explained the first releases of the tiny and harmless wasp will occur this fall in urban areas, “to help control ACP so that we do not have to do mitigations such as spraying in those areas. We hope to get to a point where we no longer need to go into people’s yards and ask if we can treat the trees.”

“The issue,” commented Valerie Melano, professor and chair, Cal Poly Pomona Plant Sciences and interim chair, Cal Poly Agribusiness & Food Industry Management/Agricultural Science, “is that we need to come up with the best possible ways to raise enough wasps for big releases to prey on ACP. We will have CDFA employees working in this green house, as well as student workers who have participated in our research program all along,” noted Melano.

Nick Hill, a Tulare County citrus producer and Citrus Pest & Disease Prevention Program (CPDPC) chair.

Hill added, “The idea is to get enough Tamarixia out there so they start reproducing themselves and they become self sufficient. This is tough to accomplish, but researchers think if they can get big numbers of the wasp into the urban areas, they can put a big dent in lowering the populations of ACP.”

Cal Poly Pomona Greenhouse

The new Cal Poly 5,040-square-foot research greenhouse, built in collaboration with Citrus Research Board and constructed through a $400,000 grant from the Citrus Pest & Disease Prevention Program, will house the second Tamarixia production program in California. CDFA’s Mount Roubideaux facility in Riverside houses current production. Both facilities will support the CPDPC biological control program that oversees releases in urban areas with high ACP populations.

The new greenhouse should produce a 1-1.5 million wasps. “It’s a very nice facility,” said Hill. “We are trying to boost the biological control program to produce four million Tamarixia a year.”

California Quarantine

The California Department of Food and Agriculture (CDFA) operates an extensive monitoring program to track the distribution of the insect and disease in both residential areas and commercial citrus groves. Results have determined quarantine zones, guided releases of biological control agents, and prioritized areas for a residential chemical control program. Nearly all of southern California is under quarantine for ACP, due to the fact that more than 15 residential trees have been discovered to be in infected with HLB.

The ACP quarantine in California includes parts of the following counties: Fresno, Kern, Kings, Madera, Monterey, San Benito, San Joaquin, San Luis Obispo, San Mateo, Santa Clara, and Stanislaus; and the following entire counties: Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare County, and Ventura.

BREAKING NEWS: ACP QUARANTINES IN MERCED AND MONTEREY COUNTIES

ASIAN CITRUS PSYLLID (ACP) QUARANTINES IN MERCED AND MONTEREY COUNTIES

Quarantines are now in place in both Merced and Monterey Counties due to recent Asian citrus psyllid (ACP) detections. One ACP was detected near the City of Merced in Merced County and two ACP in one trap within the City of Salinas in Monterey County.

The quarantine zone in Merced County measures 123 square miles, bordered on the north by Kenney Avenue; on the south by W Dickenson Ferry Road; on the west by Shaffer Road; and on the east by

E Yosemite Avenue. Monterey County’s quarantine measures 111 square miles and is bordered on the north by Pesante Road; on the south by the Salinas River; on the west by Castroville Road; and on the east by Gabilan Creek. The quarantine maps for both Merced and Monterey Counties are available online at: www.cdfa.ca.gov/go/acp-maps. Please check this link for future quarantine expansions in these counties, should they occur. Quarantines in new counties will be announced separately.

The quarantine prohibits the movement of citrus and curry leaf tree nursery stock, including all plant parts except fruit, 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 which are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport or send citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.

ACP county-wide quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare and Ventura Counties, with portions of Alameda, Fresno, Kern, Kings, Madera, Merced, Monterey, San Benito, San Francisco, San Joaquin, San Luis Obispo, San Mateo, Santa Clara, and Stanislaus counties also under quarantine.

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, such as curry leaf trees, are susceptible hosts for both the insect and disease. There is no cure for HLB and once a tree becomes infected, the diseased tree will decline in health and produce bitter, misshaped fruit until it dies. In California, HLB has only been detected on residential properties in 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 trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or your local agricultural commissioner’s office (Merced County (209) 385-7431; Monterey County (831) 759-7325).

Brexit Affects U.S. Agricultural Trade

Joel Nelsen’s Commentary on Washington D.C. Meetings, Brexit and U.S. Agricultural Trade

By Lauren Dutra, Associate Editor

Joel Nelsen, president of California Citrus Mutual based in Exeter, Calif., spoke about his advocacy for growers and the impact Brexit has on U.S. agricultural trade as he arrived at the Fresno Yosemite International Airport from Washington, D.C. last week. Brexit is an abbreviation of “British exit,” which refers to the June 23, 2016 referendum by British voters to exit the European Union (EU), according to Investopedia.

Nelsen explained, “There were two missions I was on while I was in Washington. One had to do with a proposal to allow lemon imports from Argentina. We’re definitely opposed to it because of pests and diseases, and a lack of transparency in that country over the last one to two decades.”

“We have a comment period,” Nelsen continued, “but we have asked for an extension on that comment period because of the scope of the rule and the economic impact, and we haven’t heard a word on that,” he said. “We met with our colleagues and friends in Washington, D.C. Senator Feinstein, Senator Boxer and a couple of House Office Committees have agreed to make a phone call to the Secretary of Agriculture and get a determination on that,” he said.

@SaveOurCitrus 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 to SaveOurCitrus.org and upload a photo, and citrus experts will respond.

The second purpose of Nelson’s trip was to discuss trade and the impact on the U.S. economy due to the recent Brexit, as Nelsen is chairman of the Fresh Fruit and Vegetable Agricultural Technical Advisory Committee (ATAC), a national trade committee that offers information and advice about agricultural products and trade issues to the USDA Secretary of Agriculture and the U.S. Trade Representative. “People from across the country came, and we talked about trade subjects, such as the Trans-Pacific Partnership (TPP) agreement and Britain’s separating itself from the EU,” said Nelsen. “It’s obvious that this upset everybody; Ambassador Michael Froman, United States Trade Representative (USTR) who advises the president on international trade and investment issues, said, “I know what I don’t know, and I don’t know a lot right now.”

Nelson explained, “We think [Brexit] will slow down the fresh fruit and vegetable sector, as well as the passage of the Transatlantic Trade and Investment Partnership (T-TIP). According to the USDA Foreign Agricultural Service, since the U.S. market share of agricultural products and food imported by the EU—the world’s largest importer in the category—is shrinking despite continued growth of the EU market, T-TIP negotiations offer a major opportunity to address unjustified tariff and non-tariff trade barriers to U.S. exports.

“Quite frankly,” Nelsen summarized, “we’re less than excited about [T-TIP] because it didn’t address the inherent problem that we have from competition: fresh fruit and vegetable producers in the EU get a direct subsidy and growers in the United States do not.”

Patience: How Homeowners Can Help ACP Detection

Authorities Need to Monitor ACP Detection, Confronted With Impatient Homeowners

by Patrick Cavanaugh, Farm Director

Joel Nelsen, President of California Citrus Mutual

Joel Nelsen, the president of the Exeter-based California Citrus Mutual noted that most homeowners do not realize how intensive it is for authorities to monitor traps for the Asian Citrus psyllid (ACP) at their homes.

“Most people don’t realize how intrusive this process is,” said Nelsen. “You’ve got a member of the County Ag Commissioner’s office driving down a street. He sees a citrus tree in a front yard, or he can see it’s tall enough in the back. He knocks on the door. The homeowner’s not home, so he has to come back.”

“Later, he comes back to the home and again, knocks on the door and finds that the homeowner is home. He says, ‘Can I put a trap out here to find out if you’ve got the Asian citrus psyllid?’ The homeowner hopefully says, ‘Yes.’ He comes back in two weeks. He looks at the trap. There’s no ACP. He comes back two weeks later, and if the homeowner is home, he looks at the trap,” Nelsen explained.

“It’s a constant bother to that homeowner,” Nelsen said. “Eventually, they find more than one ACP. Then the inspector says: ‘Can I spray a crop protection material on your tree and kill the Asian citrus psyllid?’”

“Hopefully the homeowner says, ‘Yes,’” said Nelsen.

Nelsen noted that the inspector visited five times already within a two month period, and now he needs to do inspect elsewhere, so having that homeowner be amenable to that much intrusiveness is a significant goal.

Nelsen noted, “The consumer education program that forms the partnership between us and them, from our perspective, is vitally important so the consumers understand what Huanglongbing (HLB)—the fatal citrus disease carried by ACP—is”.

“Then when you find Huanglongbing (HLB),” said Nelsen, “and hopefully it’s very minimal, that homeowner is more likely to agree that the tree must be removed. Fortunately, everybody has said: ‘Yes.’”
