Future of Integrated Pest Management

IPM: A Decision Making Process

By Joanne Lui, Associate Editor

Lori Berger is the academic coordinator for the University of California’s statewide Integrated Pest Management program. She spoke with California Ag Today recently about the sustainability of IPM and where it’s heading in the future.

“IPM is part of a sustainable approach to pest management. It’s very holistic. It’s a decision-making process. It incorporates all factors in an environment and in a situation, and it uses all human resources.”

Berger believes that even though IPMs are sustainable, the system might not work as well as it should.

“IPM has been around for 50 years, but our system is somewhat stuck in that we tend to be more reactive than proactive,” she explained. “If there’s an event such as an invasive pest or some … pesticide incident, some huge regulatory change or some legislative pressure, it’s like all of a sudden the system needs to reboot itself. We need to look deeper into the system and be working in a more embedded way across platforms and people.”

Berger told us that instead of looking at things in a linear way, it’s important to look at all the parts and how they relate to each other to find flaws in the system.

“As scientists, we tend to look at things cause and effect. We were looking into optimizing the whole by looking at the parts, but now taking things that are more of a systemic level, we’re trying to looking at the parts and also how they work in relationship to each other. That’s to where we can realize some of our biggest gains that there’s not as much at stake, or there’s less risk for all parties, and people are more aware of what’s going on.”

Push Back NOW with Orchard Sanitation

Part One of a Series

Orchard Sanitation Critical This Season

By Patrick Cavanaugh, Farm News Director

We recently spoke with Emily Symmes, the UC Area Integrated Pest Management farm advisor for the Sacramento Valley in statewide IPM program. She told California Ag Today about few reasons as to why Navel Orangeworm damage was so devastating this year, costing tree nut growers at least $137 million.

Emily Symmes, UC Cooperative Extension Integrated Pest Management Advisor, based Butte County.

NOW is ubiquitous. And the nut crop footprint in California is larger, with one million acres of almonds, along with pistachios and walnuts up and down the San Joaquin valley.

“The pest is not going anywhere,” Symmes said.

“We had a lot of unique circumstances. The amount of rainfall we got in late 2016 into 2017 was unprecedented and led us into a bad navel orange worm year because growers couldn’t get out and sanitize their orchards”

“Growers were not able to get into their orchards because of standing water,” Symmes explained.

Also, rainfall and moist conditions can help NOW mortality in the winter. “

We tend to think that it can help rot the nuts and do us some favors, but we have to be able to get the nuts shaken or get pulling crews in and get the mummies on the ground and destroyed,” Symmes said.

Heat units also played a part in the development of more NOW.

“It got hot. And it seemed to just not let up. Our degree-day models, or the heat unit that drive insect development, ended up getting pretty far out ahead of what is typical,” Symmes explained.

“By September, we were about two weeks ahead in degree-days, and that which meant moths were out earlier. They’re flying around. They’re laying eggs on the nuts when they’re still on the trees, and we are talking almonds, pistachios and to a lesser extent, walnuts.”

Symmes said the importance of sanitation is to minimize the site where the NOWs mature.

“It’s really important to remember that sanitation efforts aren’t just directly killing any worms that are over-wintering in your orchard. But the other thing that it does is it minimizes those sites where the first and second generations are going to develop next year,” she said.

Despite all these circumstances as to why NOW was serious this this year, it is critically important to start orchard sanitation as soon as possible. It may not be a good idea to wait for rain and fog to help loosen the nuts this season.

Napolitano Says Ag Needs Technology

UC President Janet Napolitano: Technology Drives Ag

By Patrick Cavanaugh, Farm News Director

Janet Napolitano, President of University of California, gave the opening keynote presentation on the first of two days at the recent 3rd annual Forbes AgTech Summit in Salinas in late June.

She spoke with California Ag Today, noting that technology is driving agriculture like never before.

“I think this is a great time in California history, where you have the Salinas Valley and Silicon Valley all focused on innovation and where it’s now time to have these two areas converge – agriculture and technology,” she said.

And of course, agriculture is open to new technology to help farmers produce food more efficiently and safely.

“It’s all about the world food supply; it’s all about the food supply in the state. It’s all about the economy in the state of California; it’s going to need technology to really thrive,” Napolitano said.

Napolitano noted that she has seen first hand how technologies have driven solutions to age-old problems.

“A UC Santa Barbara Materials alumnus professor, James Roger, realized that a third to a half of our fresh fruits and vegetables end up in landfills due to consumers throwing the produce out due to browning or other decomposition,” she said. “In 2012, Rogers founded Apeel Sciences, where his team created a product from natural plant extracts that can be sprayed on fruits and vegetables, which can protect them from bacteria, doubling their shelf life and therefore decreasing the amount of food waste.”

Rogers is one example of many within the UC system who have come up with innovations to help agriculture.

“We know we drive innovation by supporting innovation in our classroom and in our laboratories. And we support it with faculty, we support it with our own monies, and our own investment dollars,” Napolitano said. “And, we also bring together the private sector with the university to look at different kinds of partnerships that can be undertaken.”

The UC system has the resources to fund the early stage capital that is needed to get ideas off the ground.

“We have set aside a billion dollars of our own investment capital for early stage investment, and an additional 250 million dollars for sustainable energy technologies,” Napolitano said.

Sorghum May Be Alternative to Corn

Researcher Looks to Sorghum to Replace Corn Silage in Dry Years

By Jessica Theisman, Associate Editor

Water has been a big issue in California for the last couple of years, and many dairy producers are looking for an alternative to corn silage for when water is scarce. Sorghum silage may be a viable alternative to corn. California Ag Today met with Jennifer Heguy, a farm advisor with the UC Cooperative Extension in Merced County who is working on a project, funded by the University of California, to research sorghum.

Heguy’s project consists of looking at sorghum silage to see if it is a good replacement for dairies when California does not have enough water to grow corn. Heguy said this is, “not a good time to talk about sorghum right now because we’ve had a really wet winter and we had this devastating sugar cane aphid last year, which just decimated sorghum crops, but we are continuing to work on sorghum silage.”

With the recent emergence of the sugar cane aphid last year, the sorghum crop in California took a big hit, but the project continues. Some of these projects can take two to three years to determine if it is a good fit into the California feeding systems.

“So this year, we are going to be taking a deeper look at the sorghum quality in terms of nutrition, fermentation characteristics, how people are putting this silage up, and how they are actually feeding it out,” Heguy said.

New Estimates on Broccoli and Lettuce Production Costs

Broccoli and Lettuce Production Cost Studies Released by UC ANR

News Release

New studies with sample costs to produce and harvest iceberg lettuce and broccoli for fresh market in the Monterey, Santa Cruz and San Benito counties have been released by UC ANR Agricultural Issues Center and UC Cooperative Extension. Vegetable growers may find these useful for estimating their own production costs and potential returns on investment.

“These studies have an expanded section on labor, which includes information on California’s new minimum wage and overtime laws,” said Laura Tourte, UC Cooperative Extension farm management advisor in Santa Cruz, Monterey and San Benito counties, who co-authored the study.

The analysis is based on a hypothetical well-managed farming operation using practices common to the Central Coast Region. The costs, materials and practices shown in this study will not apply to all farms. Growers, UC ANR Cooperative Extension farm advisors and other agricultural associates provided input and reviewed the methods and findings of the study.

Both studies assume a farm operation of 1,500 non-contiguous acres of rented land. The hypothetical iceberg-lettuce farm has 250 acres planted to iceberg lettuce. The lettuce is hand-harvested into 42-pound cartons containing 24 film-wrapped heads. The hypothetical broccoli farm has 500 acres planted to broccoli. The broccoli is hand-harvested into 21-pound bunch cartons.  On each farm, the remaining acreage is assumed to be planted to other cool season vegetable crops. 

The authors describe the assumptions used to identify current costs for production material inputs, cash and non-cash overhead. Ranging analysis tables show net profits over a range of prices and yields. Other tables show the monthly cash costs, the costs and returns per acre, hourly equipment costs, and the whole farm annual equipment, investment and business overhead costs.

Free copies of “Sample Costs to Produce and Harvest Iceberg Lettuce in the Central Coast – 2017” and “Sample Costs to Produce and Harvest Broccoli in the Central Coast – 2017” and other sample cost of production studies for many commodities are available. To download the cost studies, visit the UC Davis Department of Agricultural and Resource Economics website at https://coststudies.ucdavis.edu.

The cost and returns studies program is funded by the UC Agricultural Issues Center and UC Cooperative Extension, both of which are part of the UC Division of Agriculture and Natural Resources, and the UC Davis Department of Agricultural and Resource Economics.

Cheryl Foster Talks California CattleWomen

Meet Cheryl Foster, President of California CattleWomen

By Patrick Cavanaugh, Farm News Director

Cheryl Foster is the President of the California CattleWomen and a sixth generation rancher. Her operation ranch house is in Siskiyou County, about seven miles from the Oregon border. It’s a cow-calf operation on deeded ground, as well as forest service leased ground.

“It all started back in 1871, with a livery stable in Yreka, and then when that burned down, my family went out and bought the ranch land. My grandfather, John Foster is the one who really expanded the ranch,” Foster said.

The cattle breed on the ranch is predominantly Hereford and Red Angus cross. “That cross helps a lot with the fertility and longevity of the cow,” Foster said. “It’s Northern California and pretty tough country, with hillsides and lots of rocks. You put cattle where you can’t have row crops, so it’s rough!”

Foster’s husband is a CPA; she runs the cattle operation with her brother. “My brother is responsible for equipment, and I’m responsible for the cattle and the irrigating our 450 acres of hay, so we have it divvied up well,” she said.

Foster focuses on the primary tasks of California CattleWomen. “We are trying to get the women to be engaged with the truth about the industry and keep pushing, because it’s a very, very important industry,” she said.

“We get out and tell a positive story, because I think sometimes we are afraid of what to say to counteract when people come in with wrong information. So, real important to get good information out and get the ladies confident to get out and say that we are doing a good thing for the land,” Foster noted.

Foster explained the traditional roles of the men and the women in the California cattle industry. “The men’s organization has been going for a 100 years and the women have been going for 65 years,” she said.

“Initially, the men and their organization were more on the production, and the genetics of the herd. The women started being the beef promoters, to get out there and say, ‘It’s not just about the production. People need to eat our product,’ ” Foster explained.

The CattleWomen are out and about wherever they can spread the positive word on the beef industry. They go to fairs and trade shows and participate in the California Agriculture in the Classroom, where they engage in K-12 audiences and improve agricultural literacy.

Pyrethroids Under Review

EPA Reviewing Pyrethroids

Ag Industry Urged to Comment

By Patrick Cavanaugh, Farm News Director

The pyrethroid insecticide class is in review for ecological risk assessment by the Environmental Protection Agency. John Cummings, Registration and Regulatory Affairs Manager at chemical company FMC believes that the assessment could have a large impact on producers.

Agricultural leaders have urged all to comment on the need to keep this chemistry available.  Please share your thoughts by clicking here.

“At FMC, we’re very concerned with the content of that risk assessment that they’ve identified that there’s high risk concerns to certain aquatic organisms, not necessarily fish or anything like that, but small aquatic organisms,” Cummings said. “Our concern, as a company who manufactures these pyrethroids, which are used in California, is that the EPA has not used the best science that’s available. They’ve done a very high level simple cursory risk assessment that has identified these concerns.”

More than 3,500 registered insecticides contain a pyrethroid. Many pyrethroids are household products and are not limited to agricultural usage.

“Our hope, as a pyrethroid company, is that EPA will consider better data which FMC and our industry consortium, the Pyrethroid Working Group, are developing to incorporate into this risk assessment. We need the EPA to look at the real world of how these products are used. With that, that risk assessment should look much better and remove any of these risk concerns that EPA currently has,” he said.

There have been other actions conducted by the EPA around the use of the best available data and the best science in risk assessment. These kind of precedents will impact production agriculture in the U.S. as well as California.

“EPA should be using the best science to make the right regulatory decisions while protecting the environment,” Cummings said. “It is very important, and I think it’s important, too, that EPA understand the implications of taking a conservative approach and making regulatory decisions that may impact production. I think EPA needs to understand how important it is to consider the benefit of production agriculture in feeding the world.”

It is important to keep many pest control products available to prevent the overuse of one product. Pesticide resistance is a growing problem, and it is essential that producers are able to keep all of their options open.

“Pyrethroids are a very important element of integrated pest management, as well as resistance management. Growers today are facing very complex insect control problems,” Cummings said.

“It’s necessary to have many tools in the toolbox to control insects. We have multiple classes of chemistry, but based on regulatory decisions, the EPA could potentially remove some of these important tools, which puts more pressure on other tools that remain in the toolbox, and insects may become resistant to many of these tools,” Cummings explained.

“Pyrethroids are a critical broad spectrum insecticide that are very affordable and control a lot of different insects that are economically important,” Cummings said.

Bob Klein, the manager of the Pistachio Research Board, agrees that pyrethroids are essential to pest management.

“The use of pyrethroids goes hand-in-hand with the use of soft chemicals like the growth regulators, or some of the neonicotinoids, or some of the other new chemistries we have,” Klein said.

“It guards against resistance development in those other chemicals as well. The inclusion of pyrethroids by the University of California, and many other Integrated Pest Management manuals, shows that pyrethroids are an important part of any IPM program. IPM programs are the way that people control pests in their orchards,” Klein said.

The risk assessment is currently open for comment and will remain open until March 31st.

Farm Advisor Culumber is in Awe

Catherine Culumber is Impressed by Big Production

By Patrick Cavanaugh, Farm News Director

Catherine Culumber is a UC Cooperative Extension Orchard Crops Farm Advisor in Fresno County. She has been on the job since June 30, and we wanted to catch up with her since she’s gotten her feet on the ground.

Catherine Culumber, UC Cooperative Extension Farm Advisor, Fresno County.

She came to the position with a Masters in Plant Science and a PhD in Soil Science.

“I’m so happy to be here, and it’s been great to get to know the network of people working in the University of California Cooperative Extension.  There is endless amounts of resources and wealth of knowledge that I feel really fortunate to have.”

She is working with almond, walnut and pistachio growers, with the majority of her calls from almond producers.

Culumber was surprised with the vastness of Fresno County and all the production here. “My PhD research was in orchard systems at Utah State University, and it didn’t nearly prepare me for the infinite acreage that I saw upon arriving here,” she said.

She said that she has met some very innovative growers, and they all seem to be doing the best they can for the family farm.

“I think that farmers are very adaptable, and I can see that in recent years with the decrease in water availability, most people have adapted and gone to different micro-irrigation systems to increase their water use efficiency,” Culumber said.  “The farmers are working hard to not only be sustainable, but they’re smart business people as well.”

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

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

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

 

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

 

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


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

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

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

Initial Walnut Irrigation Can be Delayed

Walnut Irrigation Research Update

By Brian German, Associate Broadcaster

 

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

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

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

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

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

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