How vegetable growers can get ahead of upcoming pesticide regulations - Fresh Fruit Portal

Posted: 30 Nov 2020 03:24 AM PST

By Thomas Grandperrin of UAV-IQ Precision Agriculture

This article is part of a series on biological control and Integrated Pest Management written by UAV-IQ (www.uaviq.com).

In an industry that is constantly shortening the list of allowed pesticides in the vegetable grower's pest management tool kit, adopting alternative pest control strategies is not just "nice to have" or reserved for organic growers anymore - it is a way for farmers to ensure they'll be able to stay in business in the long term.

Alejandro Del Pozo, a former University of California cooperative extension entomologist and now assistant professor at Virginia Tech, is a firm believer that alternative pest control methods are the way of the future and has made it his mission to help growers getting ready for upcoming regulations and adopt alternative pest management practices.

Originally from Perú, a country with a long history of using augmented biocontrol in outdoor crops, Alejandro identifies himself as an applied insect ecologist. He started his career as an asparagus farmer in his home country, where he was also in charge of a beneficial insects breeding facility. During his career he has worked with a wide variety of crops: from hybrid poplars during his masters, to soybean for his PhD, to corn and cotton during his postdoctoral work.

Alejandro started to work as an Integrated Pest Management (IPM) and entomology advisor with the University of California cooperative extension in 2018. Based in Salinas, he developed successful research and extension programs focused on aiding growers of multiple types of leafy greens and cole crops to implement IPM's best practices.

The relationship between macro-organisms in different agricultural systems and the alternative control tactics for implementing an IPM strategy has been a consistent theme throughout his career. This theme came up again during our conversation. We discussed the need for vegetable growers to get ahead of upcoming pesticide regulations by using conservation and augmentative biocontrol in vegetable crops as well as new technologies available to IPM practitioners, namely drones to release beneficial insects, manual weeding robots, and automated insect traps.

The need for growers to adopt pest control alternatives to stay in business

Most vegetable growers are making tremendous efforts to keep up with the switch in consumer demands and to respond to environmental and health concerns, but Alejandro observes that in conventional farming, "There are still a lot of pest control tactics that rely on pesticides like neonics because those chemicals are really effective.2

"Growers currently use them to control devastating virus-transmitting pests such as aphids. But we started to pick up residues of neonics on surface water and we can see that they have a negative effect on pollinators, that pests develop resistance… and there's more science constantly coming up looking at the non-targeted effects of those products."

So, will active ingredients like neonicotinoids be further regulated? Looking at areas of the world with stricter regulations, such as the European Union where the use of neonics is already prohibited, may predict what's coming for growers in the United States and other countries.

Alejandro reports that, "In the next three to five years, these regulations about the use of neonics and pyrethroid are gonna come. For example, the EPA is currently revising the use of seed treatments using neonics. Some of the crops will not be able to do in-farm seed treatments anymore. You'll have to hire a specialized company to use seed treatments, because there is research to prove that in-farm treatments create dust which moves around the entire ecosystem".

He advises growers to prepare for these scenarios as part of their risk management strategy. "We need to change our mindset about how we use pesticides. For example, you're already no longer able to buy chlorpyrifos in the United States. So that set the example of what could happen. It is possible that the EPA or other regulators will restrain the use of neonics."

Alejandro continued, "I always ask the growers I talk to: 'What happens if tomorrow we are not allowed to use neonics and pyrethroid. Are you going to go out of business?' The answer that I got is usually 'yes'. And that's scary, because that shouldn't be the answer. The answer should be, 'Well, this works now, so what could be the alternatives to overcome the lack of this really great chemistry that helps us do pest control right now? Is there any alternative?'"

Are there any practices and technologies that can already help growers to reduce or at least improve the use of those pesticides? According to Alejandro, the answer is a resounding "yes". He believes it's a matter of intensifying extension efforts to promote those new pest management techniques and for the growers to change their mindset about pest control and look for those alternatives.

Biological control, an efficient pest management methods for vegetable row-crops

Potato aphids, foxglove aphids and lettuce aphids are some of the most economically devastating pests of leafy greens and other vegetables. In lettuce, those aphids like to infest the interior of the plant. When this happens, natural enemies have a clear advantage over insecticides. They have the ability to hunt their prey where they hide.

Alejandro explains that, "Even if you're spraying something like pyrethrins and spinosad, you're not going to have control because you're not going to get the product inside the head of the lettuce. The maggot of the syrphid fly, on the other hand, goes inside the lettuce head where it devours the lettuce aphids."

So if natural enemies are so effective at controlling pests like the aphids, why aren't all growers leveraging them? Alejandro believes that one of the strongest barriers to the adoption of biocontrol in vegetable production is that there are many negative preconceived ideas about conservation and augmentative biological control that deters vegetable IPM practitioners from implementing it, namely that it is too expensive and too much work.

In the case of augmentative biological control he explains that, "Beneficial rearing laboratories are getting better, the prices are getting cheaper, we have technology like drones to release the beneficials... So I think, based on my little experience (Note: Alejandro has been doing biological control since 2003), that now more than ever is a good time to actually consider using laboratory-reared beneficials to do augmentative biological control."

He believes that those preconceived ideas and barriers to adoption need to be fought through research projects and extension efforts, showing that biocontrol implementation can be done.

"I led a couple of projects on conservation and augmentative biological control in vegetable production that show that it's an investment that pays off. Once growers get into the routine and have a carefully planned program for augmentative biological control, I think it will flow seamlessly. It will be something that will become normal as part of their management strategy."

Forward-thinking growers are taking it upon themselves to lead the industry and adopt new technologies and practices, through field trials in partnership with commercial companies. Thanks to the efforts of these industry standard-bearers, new treatment protocols are available to growers located throughout the technology adoption curve.

How can vegetable growers get started with biological control?

How can conventional growers get started with biocontrol? "I used to be a farmer, so I understand that growers want to make sure that they can rely on an easy control tactic like an insecticide to get rid of a pest if they have an issue," Alejandro empathizes.

Unfortunately, the overuse of broad-spectrum insecticides remains one of the main problems that forward-leaning growers need to address before starting with biological control. Alejandro encourages growers that, "Reducing the use of broad-spectrum insecticides will open the door for combining biological control in terms of conservation and augmentation."

Before completely removing insecticides he suggests that the first step would be to space apart the applications of broad-spectrum insecticides as much as possible. "If you are on a high intensive vegetable crop that you're usually spraying once a week, can you spray the broad-spectrum insecticide once every other week? You can start playing around in between those two weeks to test something that could fit into your program, and start transitioning to newer chemicals that don't impact beneficials as much."

After decreasing pesticide usage, the next step is intercropping. The implementation of conservation biological control techniques, like the addition of insectary habitats in the field such as sweet alyssum intercropping, is already widely used in the Salinas Valley. "Sweet alyssum provides pollen habitat and attracts the beneficials like the hoverfly, which will later move to the lettuce to feed on aphids." This has been well documented in Salinas, and people from the University of California, the USDA, or private companies (like Gina Colfer of Wilbur Ellis) have played a crucial part in promoting this technique.

Alejandro highlights one strong argument in particular which resonates with conventional growers who still need a little extra convincing before committing to the modest step of adding insectary plants. "The data that we generated from specific research projects prove that when you intercrop Alysum, you're not losing yield, so it is a really good way for a conventional grower to step into the biological control world. I think that to break the barrier to the adoption of biocontrol, starting with those conservation biocontrol practices, namely reducing pesticide use and intercropping insectary habitats, are what brings everyone to the table."

Once this is done, he explains that, "Those insectary plants will become your islands where you can release commercially reared beneficials insects."

Augmentative biocontrol of aphids in the Salinas Valley leafy-greens

As growers reduce or remove broad-spectrum insecticides and start using sweet alyssum intercropping, they will start seeing effective aphid control thanks to the naturally occurring predators. But despite the best conservation biocontrol efforts, aphid outbreaks can happen. That's when growers can start releasing commercially reared beneficial insects, such as green lacewing larvae, to keep the aphid population in check.

The moderate climate in the Salinas Valley allows beneficials to be released most of the year. Applications should be performed once, and in some cases twice, per crop cycle. For vegetable growers in the Salinas Valley getting started with augmented biocontrol, the beginning of the summer is probably an ideal time for a release. "That's when the aphid infestation is coming up in Salinas. So you probably want to target those specific timeframes where there are a lot of pest populations out there,"Alejandro suggests.

The threshold that should be used to trigger a lacewing release for aphid control will depend on the area and the crop. As a generalist predator, lacewing larvae can also feed on pests like spider mites, thrips, whitefly, and small caterpillars, while adults will feed on the pollen of the insectary plants. But, as a general rule, the release should be performed when there are enough aphids that they can feed on. He reports that, "There is some literature that says that lacewings have this functional response, and it aligns with what we saw. So the more aphids that you have, the more predation you end up having."

He acknowledges that it can seem like a contradiction or a difficult thing to assess. "You don't want to see the aphids. But you also need the aphids to actually provide the food for the beneficials. So it's quite a dance, right?" But growers should be reassured that there are knowledgeable Pest Control Advisors (PCAs) and local IPM experts that can help them decide when it's the right time to do a release.

Alejandro concluded by confirming his faith in the use of augmentative biological control. "Based on my experience, I can tell that lacewings really help knock down the aphid population. While they don't completely wipe them out and growers might need to use complementary control tactics, the idea that you can reduce the population significantly was really impressive to document."

How drones can help vegetable growers implement biological control at scale.

When implementing augmentative biocontrol in large vegetable fields, growers can face challenges due to labor shortage or to the insufficient quality of manual beneficials releases.

While at the University of California, Alejandro did a set of trials with a technology recently gaining in popularity among IPM practitioners: drones.

He explains that, "Using systems specially designed to release beneficial insects and mites mounted on commercially available drones, we released green lacewings in lettuce crops to target aphids."

One of the goals of the study was to prove the survival rate of the beneficials being released through this kind of system. "We've been able to recover some of the lacewing larvae from those fields and we showed that aphids population can be reduced by up to 50%!"

Alejandro also did field trials releasing Amblyseius cucumeris for thrips management in ice plants that some growers use on roadsides to control erosion. Since they always have flowers, they attract thrips. The idea was to use the ice plant as a trap crop and then release cucumeris in those ice plant patches. "Not only could we recover cucumeris from the areas where we released them with the drone, we were also able to show that there was a lower thrips population densities in the areas that we treated compared to the controls that were untreated."

Emerging technologies improving the efficiency of pest monitoring in vegetable production

Drones are not the only emerging agriculture technologies helping vegetable IPM practitioners. Alejandro believes that, "Mechanisation and automation is the way to go. It's how agriculture is moving forward. I believe it's not going to get anyone fired. It is not the evil of losing jobs. On the contrary, I think automation, remote sensing, you name it, is gonna help us get more efficient in our processes as growers."

He mentions his own experience with pest remote sensing in the past few years in the Salinas Valley. He's been using pheromone traps equipped with four high-resolution cameras on top of it, taking pictures once a day. These pictures are then centralized in a cloud database and stitched together to create a single image.

Alejandro explains that, "The computer has its own artificial intelligence algorithms to recognize the pest, in this case diamondback moth adults. They count them and automatically send an alert at the end of the day with the number of trapped moths it has detected. This new automated and remote monitoring gives growers that opportunity to be on top of a hotspot to try to be ahead of the game."

He adds that, "We proved the concept that those traps are really accurate compared with regular weekly checking of the monitoring traps. This technology is now getting mainstream, so it's going to be more affordable for growers. It will be of great help for IPM practitioners to have this data and these alerts on the palm of their hand."

Alejandro is now exploring possibilities of implementing this technology at his new assignment in Virginia, in turfgrass or crops like hemp.

Solving labor shortage and sustainability issues in leafy greens with precision spraying and automated mechanical weeding.

Besides harvesting, one of the most important tasks of leafy greens growers is probably weeding and thinning. But when growers can only count on a limited number of workers and are constantly pressured to limit their herbicide use, what is the solution?

Alejandro is excited about the advance of robotics in this field that will impact leafy greens IPM practitioners. He explains that, "If we get more regulations on insecticides, we need to prove that we're doing a better job at spraying them. Precision spray allows spraying at the plant level. The computer that goes into the thinner with the tractor is recognizing every single lettuce and then taking some measurements before spraying the insecticide and the fungicide, that way growers avoid doing broadcast treatment."

He gives some examples. "Companies like Mantis are doing a great job using compounds that help do the thinning in vegetable row crops, which is usually a high concentration fertilizer and a little bit of herbicide. They also have a secondary tank where you can put a fungicide and an insecticide and it's sprayed at the plant level. So you will have no drift and you are going to reduce the total amount of active ingredients per acre."

Automated thinner from the company Mantis

The other approach is mechanical weeding. He relates that, "Other companies like Farmwise do automated mechanical weeding, taking out the weeds using blades. But they're thinking about putting spraying systems and also infrared sensors to actually help growers understand what is the health status of the plant. So the visual information that those robots will capture will allow for improved yield forecasts based on the diameters and the colors for example. That will be something that's going to tremendously help the grower with the marketing and the contracts. So it's a spiral of really great benefits that technology is bringing to the growers that actually need information to do the management. I really believe these companies are visionaries."

Alejandro adds, "I'm going to sound like a broken record, but labor is getting scarce and difficult to get. Growers constantly need to prioritize how to which task they assign their crew. You need people to harvest to get the product out of the field. So if you can rely on automation to help with the weeding, thinning, and biological pest management this is something less that growers need to worry about. So these companies are filling the void."

An exciting time to work in agriculture

As a conclusion, and despite the challenges faced by the agriculture industry, Alejandro believes it's an interesting time to work in agriculture, thanks to the progress brought by entomology and biology research in the field of natural pest control strategies in parallel to the advance in agriculture technology and robotization. "I am excited to do agriculture right now and in the future because we have all this, biocontrol, drones, sensors, and artificial intelligence... It's going to be fun."

Hopefully, this enthusiasm will be reflected in the future generations' eagerness to follow a career in agriculture.

Q&A: How nutrition professionals can take an evidence-based approach to debunking food myths - SmartBrief

Posted: 30 Nov 2020 08:39 AM PST

This post is sponsored by the Ajinomoto Group.

There is a lot of misinformation out there when it comes to food and nutrition, and many people can easily be swayed by opinions and false facts that lead them to make misguided choices. In this interview, food, nutrition and media communication consultant Kathleen Zelman, MPH, RDN, LD, discusses what leads people to believe myths about certain foods and how nutrition professionals can use scientific evidence to combat misinformation.

How can myths and personal bias cloud the interpretation of scientific evidence and lead to misinformation?

Even though we all have our own personal opinions, nutrition is a science, not an opinion. Bias often comes into play when talking about controversial topics or when there is insufficient data, when emotions take over and misinformation flies in the face of evidence. Confirmation bias describes searching for information, or "cherry picking" data, that is consistent with one's beliefs. If our views are not in line with the evidence, it is our responsibility to make an objective, unemotional analysis of the facts and clearly communicate the weight of the evidence or lack thereof when there is limited evidence.

How can nutrition professionals use the weight of scientific evidence to debunk myths?

One study in isolation does not change public health advice, but unfortunately, sometimes it can change public perception. Food and nutrition are vital to good health, but myths can perpetuate unhealthy behaviors and affect health and wellness. It is our professional responsibility to communicate the body of evidence in context and help people understand how it can support their personal goals. Before doing so, we must appreciate where that person is coming from and seek common ground to help them be more open minded to our advice. Advice delivered with warmth, a caring demeanor and compassion is most likely to be heard.

What are some hot topics in food and nutrition that are generating myths or misconceptions, and what should nutrition experts keep in mind when evaluating the evidence?

One example is the resistance to genetically modified organisms, despite the fact that they have been in our food supply for more than 20 years and the National Academies of Sciences, Engineering and Medicine has found "no substantiated evidence of a difference in risks to human health between current commercially available genetically engineered crops and conventionally bred crops."¹ Another example is monosodium glutamate (MSG), a common household seasoning that has been used in food for more than 100 years. Despite a conclusive body of evidence showing that MSG is safe, many people still associate it with various symptoms, although these have not been consistently demonstrated in placebo-controlled, double-blind trials.² Fight misinformation by staying up to date, reading the literature -- not just the press release, looking critically at the prevailing body of research and consulting authoritative public health institutions.

Why is it that some people still choose to believe myths and misperceptions about certain foods despite the scientific evidence debunking these claims?

When people choose to believe myths in spite of the science, it's often rooted in emotional or psychological reasons. To use MSG as an example again, consider a recent survey from researchers at Behavioralize, which was supported by Ajinomoto, to better understand why some people avoid MSG despite evidence that it is safe. The findings suggest people's avoidance of MSG is rooted in emotions, feelings and misinformation found on the internet that they believe to be true³. Another interesting finding is that people who avoid MSG do not have a factual understanding of the ingredient, but they believe they do. Scientists refer to this as the "Dunning-Kruger Effect." It could also be that it sounds like a chemical and its name creates "chemophobia." We must put the issue into context and help people understand the science while also keeping in mind the emotional weight that comes with people's decisions and beliefs.

What are your thoughts on industry-funded research? What benefit does it provide to the body of scientific evidence and the industry?

All research should be judged on the quality of the study, regardless of the source of funding. Industry-funded research, like all research, is obliged to transparency and disclosure. When funding is not reported, the quality rating of the research is more likely to be diminished. Multiple studies have shown that there is no significant difference in favorable conclusions or quality of research between industry-sponsored studies and studies that are not industry-funded^{4, 5}. For instance, a study looking at research by the dairy industry found no significant differences between industry- and non-industry-funded studies⁶. In order to garner trust, we need to promote sound science in context and analyze the research with a critical eye. As RDNs, it is also our ethical responsibility to uphold the code of ethics of the Academy of Nutrition and Dietetics.

How should professionals communicate advice when the science is emerging?

There is very little black and white in nutrition. Nutrition research is often in the "gray" zone. Evidence-based guidelines and systematic reviews are considered the best available sources, but when these do not exist, such as the case with emerging science, then primary research or expert consensus is the next best available. Form a judgment knowing there is uncertainty, using the best tools to interpret and communicate the latest science.

When it comes to emerging research, be clear that the research is emerging, put it into context and always remember "do no harm." It's ok to convey uncertainty and, in fact, you're more likely to build trust this way. Our job is to offer the prevailing expert consensus over confusion, and stand united as nutrition experts, serving as a balanced and level-headed information hub, especially in a time of fake facts and harmful trends.

Kathleen Zelman, MPH, RDN, LD is a food, nutrition and media communication consultant and owner of No Nonsense Nutrition, LLC. She recently retired as the director of nutrition for WebMD, where she helped build a state-of-the-art food, diet and nutrition portal. She currently serves as a contributing editor to the Academy of Nutrition and Dietetics' Food & Nutrition Magazine, is a member of the board of directors of the True Health Initiative, Inc. and Nutrition4Kids' medical advisory board, and is a nutrition expert for the Ajinomoto Group.
