GMO Technology Can Help Prevent Starvation

First World Activists Dictate to Third World

By Patrick Cavanaugh, Editor

Needed GMO technology to help citizens in Third World countries is being thwarted by activist groups in First World countries who are anti-GMO, said Alison Van Eenennaam, a UCANR Cooperative Extension Specialist focused on Animal Genomics at UC Davis.

“If the African people choose to use this to develop better bananas, they should have the right to use that and not be dictated to by activist groups in the First World promoting fear around this technology,” she said.

GMO technology could greatly benefit those in the developing world, especially those who struggle with starvation on a daily basis.

“Most people have never seen starvation. People take food for granted, and when you see people that have problems in their agricultural production systems that are actually affecting the food security, you have to address those problems, whether they be drought or disease problems,” Van Eenennaam explained.

“And I’m all for using whatever technology that works best to address a problem. Maybe it’s conventional breeding or maybe its GMO, or gene editing. I don’t really care. I just want to use the best tool that is available. But it doesn’t make sense to take some tools off the table for no reason, and I think that’s what’s happening around the debate of genetic engineering,” she said.

And the use of GMO crops in a third world country has dramatically decreased the use of pesticides, which should be celebrated by activists.

“About 90 percent of the farmers growing GMO crops are on small acreage producers in the developing world, that are growing insect-protected Bt cotton. And the dramatic decrease of insecticide use resulting from that—well environmentalist should be singing this from the rooftops,” Van Eenennaam said.

“It’s incomprehensible to me that if your real intent is to decrease pesticide use in agriculture, to not appreciate what those Bt crops have done for global insecticide use is to be willfully ignorant of what the data shows,” Van Eenennaam said. “It’s just a win-win for everyone.”

Helping Anti-GMO Consumers Know the Truth

Van Eennennaam: It’s Tough to Change Emotion

By Patrick Cavanaugh, Editor

California Ag Today recently spoke with Alison Van Eenennaam, a UCANR Cooperative Extension Specialist focused on Animal Genomics at UC Davis. She discussed the argument against GMOs and the difficulty that some science communicators have with reaching anti-GMO consumers whose arguments are more emotion-based than fact-based.

“When every major scientific society in the world says something, then I don’t believe it’s a giant conspiracy theory,” Van Eenennaam said. “I believe that’s what the data show, and I get a little bit frustrated when people cherry pick an outlining study and just selectively ignore the consensus opinion of every single scientist in the world. That doesn’t make sense.”

“It becomes more like a denialist instead of a skeptic at that stage. Then discussion around the safety of GMOs is just out of kilt with the actual scientific data. It’s frustrating trying to correct that with science because it’s very hard to counter an emotional argument. So we need to peel back the story in a narrative form,” she said.

Van Eenennaam highlighted a movie called Food Evolution, narrated by American astrophysicist Neil deGrasse Tyson, which presents a factual representation of GMOs.

“I think that’s what’s been encouraging to me, just with general audience populations watching it, is they’ll come up afterwards and say, ‘You know what? This film made me think.’ ” Van Eenennaam said. “As a science communicator, I cannot ask for more than that. That’s exactly what I want people to do. I want them to dig down into the data and recognizing where they are getting the information and what it’s saying. I think that is a positive outcome.”

And certainly the movie has changed the mind of some people.

“And that is great, but we are wanting people to reevaluate on why they are changing their minds and are they willing to change their minds based on the evidence? That is one of the focal points of the movie,” Van Eenennaam explained.

The Food Evolution movie can be seen free if you subscribe to Hulu. It can also be seen in different areas on the web. Simply search for it online.

California Coffee Brews Success

Mark Gaskell on California Coffee Crop

By Laurie Greene, Founding Editor

California Ag Today recently spoke about the emerging California coffee crop with Mark Gaskell, who covers San Luis Obispo and Santa Barbara Counties as farm advisor for the University of California Small Farm Program as well as the UC Division of Agriculture and Natural Resources (UCANR) Cooperative Extension.

“Currently, there are about 30 farms with maybe 30,000 coffee plants between San Luis Obispo and San Diego Counties,” Gaskell said. “I would expect that to double this year. California’s coffee crop is doing well.”

“There is also now a private company, Frinj Coffee,” explained Gaskell, “that evolved out of a long relationship I had with Jay Ruskey, CEO and co-founder of Goleta-based Good Land Organics. Ruskey participated in some of our early research and development work with California coffee. Our collaboration has justified investment by the number of coffee growers in the Frinj Coffee operations.”

There are 25 growers, according to the Frinj Coffee website.

Coffee cultivation is new to California, because, as Gaskell explained, “traditionally, coffee is grown in subtropical areas, specifically at high elevations where the relatively cooler temperatures are. Cooler temperatures prolong the ripening time, which improves the quality of the coffee beans.”

“So, in the world’s newest coffee growing region, Coastal Southern California,” Gaskell said, “we replaced the high elevation with the influence of the Pacific Ocean. The ocean delivers a huge mass of relatively cool temperatures—always between 50 and 60 degrees Fahrenheit. These mild coastal conditions enable a very long ripening season for the coffee cherries and coffee beans.”

Gaskell projects the California coffee crop will be very successful.

“We expect the coffee volume will double this year and probably continue to double for the next few years. Just based on existing interest in coffee, I expect demand to keep pace with the ability of California growers to supply it, and more and more growers will be planting it this year.”

Specialty Farms Grow for A Diverse Customer Base

Small Specialty Farms Specialize on Niche Crops

By Jessica Theisman, Associate Editor

Mark Gaskell UCANR Small Farms Advisor

Cal Ag Today recently spoke with Mark Gaskell, a University of California Cooperative Extension Small Farm and Specialty Crop Advisor for San Luis Obispo County. He explained the definition of a small farm.

“I remember the USDA used to define a small farm as a $250,000 in gross income or a $350,000 in gross income,” Gaskell said.

Gaskell also works with specialty crops that are lower in volume but are high value crops.

“I don’t ask small farmers what their gross sales is by any means, but because of the emphasis on these specialized niche crops, I tend to see more small scale farming operations,” Gaskell said.

Blueberries are a perfect example of a specialty crop in California. With a large, diverse population, this pushes the growers to continue producing high-quality fresh crops.

Blueberries were originally grown in the eastern United States because they like the acidic soil. Of course California growers found a way to amend the soil to drop the pH.

“Because of California’s diverse population and appreciation for high-value, fresh market items, we tend to avoid more commodity-type crops. Small farms need to specialize in fresh market, high value crops for this diverse population base,” he said.

Small Farms Must Include Marketing

Marketing Makes it or Breaks it

By Jessica Theisman, Associate Editor

Mark Gaskell is with the University of California cooperative extension as a small farm and Specialty Crop Advisor for San Luis Obispo County. Gaskell recently told California Ag Today about his work with growers and small farms in the county since 1995.

“Part of my job has to do with applied research and educational programs, and this case related to keeping small farms viable and successful,” Gaskell said. “These activities include troubleshooting problems, helping growers develop new crops and develop new market opportunities that make them more competitive.”

The big question is, what to plant and how to profit from the crops?

“I often tell growers, plan on spending half or more of your time on marketing because marketing is probably more important than growing,” he said. “Marketing is what will draw crowds. It is best to have a marketing plan for your crop before putting your seeds in the ground.”

“Some opportunities are direct sales via farmers markets or farm stand, but more often than not, those market outlets are full and there is a long waiting list,” Gaskell explained.

Growers have to then look at selling through specialized wholesalers and in some of the metropolitan areas, Gaskell said.

Herbicide Limits Plantings Following Cilantro

Caparol Label Change Sought To Reduce Plant-Back Restrictions Following Cilantro

By Patrick Cavanaugh, Editor

Cilantro production is important in California and more growers are planting it. However, an herbicide used in cilantro has plant-back restrictions to other crops.

It’s easy to grow and works well as a rotation crop, explained Oleg Daugovish, a UCANR Cooperative Extension Strawberry and Vegetable Crop Advisor serving Ventura County.

“It’s an easy fit in our production systems. You can fit it between many crops,” Daugovish said. “It’s a quick crop and can be planted in a small planting window.”

To help minimize weeds, Caparol herbicide is labeled for use on cilantro. “It works very well and it’s all we need to control weeds in cilantro,” Daugovish explained.

“But the problem is that we have some plant-back restrictions. Some of the crops, we obviously have to rotate your cilantro with something,” Daugovish said. “You have to have a label that allows you to go back to the field with other crops such as peppers, lettuce, Brussel sprouts or spinach.”

That’s the biggest problem for growers, as they like how it works on cilantro, but need an allowance to go back in with different crops without worry.

Under the IR-4 program, Daugovish conducted research to see if other crops could safely be planted after a cilantro crop. The research indicated that crops following cilantro within the plant-back restrictions were safe for the most part.

“They treatments were similar to the untreated,” said Daugovish. “We are putting some numbers together and running statistics in different locations such as Salinas, Santa Paula, and Ventura.”

Daugovish said it appears that it is safe to follow cilantro without waiting for plant-back restrictions, and he plans to submit the data to the IR-4 program who can get it to the registrant who can amend the label.

“We need to make the change on the label so growers can use it without the plant-back restrictions,” said Daugovish. “We expect to have the data sets to support a label change so that growers can use it.”

“As far as herbicides, we may not have another option for a while, but if growers can use is safely with peace of mind it will be a major benefit,” he said.

Grain Diseases Must Be Closely Monitored

Diseases are Always Evolving

By Patrick Cavanaugh, Farm News Director

Mark Lundy is a UC Cooperative Extension Specialist in grain cropping systems at UC Davis. Lundy runs trials on grain crops because California is such a diverse environment and there are different conditions from year to year so it’s important to be consistent in measuring yield and crop quality, grain diseases, and agronomic traits on small grains.

Lundy’s work is predominantly on California wheat, but there are many trials on barley.

“Improved varieties have been the mainstay of my work,” Lundy said. “I came at it from a water and nitrogen management background, and one of our goals is trying to disentangle the environment that you can’t control from the environment that you can control. But this is the second year where we have some of those gradients in there so we are trying to maintain the attributes we have, while also trying to add some value.”

And diseases have been closely monitored within the trial system, noted Lundy.

“We do try to keep track of disease, and so when there are diseases of concern such as stripe rust, which was historically a big problem for growers, it has been successfully addressed through breeding,” he said.

The breeding is spearheaded by Jorge Dubcovsky, a professor at UC Davis Department of Plant Sciences working on wheat genes.

“Stripe rust is still something we have to keep an eye on, and it’s certainly a disease that is always evolving,” Lundy said. “And because resistance is not permanent, we’re always looking for the big diseases that can be detrimental to the production system, such as stripe rust.”

“We also keeping track of leaf rust,” Lundy said. “I’m not a pathologist by training, so I’ve been learning on the job, and I’m grateful to the former UC Cooperative Extension Specialist Lee Jackson, who was a pathologist. He created a nice knowledge base for us to build on.”

American Society of Agronomy Meets

Plant Soil Conference Discusses Nitrogen Management

By Patrick Cavanaugh Farm News Director

Dan Munk is a UC California Cooperative Extension Fresno County Farm Advisor who specializes in irrigation, crop nutritional management and cotton production systems. He recently spoke about the California chapter of the American Society of Agronomy holding its annual plant and soil conference recently in Fresno. Attendance was great, and agronomic issues regarding water, irrigation and nutritional management were covered.

“[The] California chapter of the American Society of Agronomy convenes a annual meeting known as the plant and soil conference, which was held recently in Fresno for a day and a half. We had the CDFA Secretary Karen Ross address the group as well as some nutrient management experts from across the state and outside of the state,” Munk said. “And we discussed agronomic issues related to water irrigation, nutrient management in agriculture. And there was a pest management session as well.”

There were more than 220 top state agronomists, with many Certified Crop Advisors as well as some growers and industry affiliates attending that meeting.

Nutritional management plans for efficiency, especially for nitrogen, are being closely looked at and discussed.

“I think the nutrient management plans that we’re doing is something that we need to continue to get better information. We have an understanding now of where some of the limitations are now for efficiencies,” Munk explained. “I mean, we can’t always be 100 percent efficient in these things and when we are, that’s when you get into the situation where you have some yield losses. So there’s, there’s always going to be some nitrate movement out of the root system in agricultural systems. That’s just the nature of the beast.”

Groundwater Nitrates Due to Legacy Issues

Minimizing Groundwater Nitrates

By Patrick Cavanaugh, Farm News Director

Groundwater nitrates have been a concern over the last decade and growers have made much improvement to minimize the problem. But still, new regulations are requiring that growers not make the problem worse.

California Ag Today recently spoke with Dan Munk, a UC Cooperative Extension Fresno County Farm Advisor, about the topic. He specializes in irrigation crop nutritional management and cotton production systems. He explained that when water leaves the root zone, it takes away salts and nitrates.

The issue is that irrigated agriculture is always going to have some water leaving the root zone simply to leach salts.

“And when you leach salts, you take away with that water, along with something like nitrates. So that’s part of the system,” Munk said.

“And so what we can do in agriculture is limit those losses and try to be more efficient because it still makes us more efficient in that we spend less money on fertilizers that way,” he said.

“However, there’s always going to be some losses to … systems over time, and I think that’s the best we can do,” Munk said.

He said that many of the nitrates in the ground water are due to legacy issues. When growers had different irrigation systems or when growers had different access to water.

“Today, we’re applying a lot less water, much more uniformly and have been for many years. Things really have changed in terms of the amount of nitrates that are going below that root zone and into the groundwater,” Munk explained. “It is much less today.”

Rootstocks Offer Production Attributes

Tomato Rootstocks Grafting

By Jessica Theisman, Associate Editor

California Ag Today recently spoke with Brenna Aegerter, a UC Cooperative Extension farm advisor in San Joaquin County, about grafting rootstocks to tomato plants.

“Rootstocks are cut below the cotyledons, while the scions are cut above the cotyledons at an angle,” she said.

These two plants are then clipped together and go into a high humidity healing chamber for about one week.

Aegerter explained that, “In the beginning, there is no light. They gradually increase the light because they do not want to stress the plants, and so if those two angles match … then everything grows back together.”

Each tomato plant can differ depending on the rootstock that it has been grafted to. Different rootstocks have varying levels of resistance to disease and pests. Rootstock resistance does have an effect on crop yield. If all of the fruiting varieties had the nematode resistance gene, they could potentially improve their yields.

There is great success rate on grafting these tomato plants.

“We have had pretty good success, 90 percent and up,” Aegerter said.

The remaining 10 percent is because the angles were not matched up quite right and there is not enough contact between the two tissues.

“Rootstocks are for the most part, hybrids between our cultivated tomato and wild tomato species,” Aegerter explained.

Wild tomatoes are used often to bring in new genetic material due to their diversity and natural resistance. Depending on the type of tomato that is being used, the resistance can differ.

The fruiting varieties are resistant, but are resistant to a shorter list of diseases.

“These root systems are are bigger, the crown is bigger, and sometimes they aren’t even purely resistant to the disease, but just by virtue of the fact that they grow faster, they can outgrow it,” Aegerter said.
