Timorex Gold, Broad-spectrum Biofungicide

Biofungicide Timorex Gold to Help Western Vegetable Growers Fight Disease Pressure

By Patrick Cavanaugh, Farm News Director

The U.S. EPA has approved Timorex Gold, a new broad-spectrum reduced-risk biopesticide that is already a leading biofungicide in Latin America to control black sigatoka, a leaf-spot fungal disease on bananas, for various domestic crops such as tomatoes, strawberries, as well as other berries, cucurbits, grapes, tree nuts, and lettuce.

Timorex Gold is well positioned for American crops because it is known to be effective on powdery mildew and Botrytis on strawberries and tomatoes, plus bacterial blight on tomatoes.

Sarah Reiter, country manager of STK Stockton, an innovative Israeli company that opened its U.S. headquarters in Davis, CA. “We are very excited about the products performance we are seeing in areas where it is registered,” said Reiter. “We are happy with the label the EPA granted us. We still await registration in California and anticipate it next year or possibly late this season.”

Reiter noted the highly effective active ingredient in Timorex Gold, the plant extract Meluleuca alternifolia, or tea tree oil, gives growers a powerful new tool to control both bacteria and fungi diseases. “We know growers do not have a lot of choices for bacterial control,” said Reiter, “so any new active ingredient is a good thing. This product has the added bonus of being a fungicide too.”

“Timorex Gold has been established as a primary control product for sigatoka because it performs so well,” Reiter commented. “Growers use it because of its profile, and it’s easy to use. And while the product is a biopesticide, once the growers get it in their hands, they tend to forget it’s a biopesticide because it performs as if it is a synthetic material.”

“As an industry we have been looking for this for quite a long time,” Reiter reflected. “While biologics have been around for a century, historically, growers would have to give up some levels of control in order to implement them into a conventional program. We do not see that loss when using Timorex Gold against sigatoka disease.”

“Our expectation in the U.S. is that growers will see that same high level of performance when they use the product here,” Reiter said. “And since Timorex Gold is a biological, there is no concern for Maximum Residue Level (MRL) data because there is no residue on the crop. The product will have very short re-entry intervals (REIs) and preharvest intervals (PHIs), as well as flexible application intervals, a strength that growers like because it gives them a lot of flexibility to implement the product into their program when they need to instead of having to manage REIs and PHIs.”

In addition, Timorex Gold has a very low designation of FRAC 7¹, which means the product has a unique mode of action that can be used in alternate succession with other fungicide modes of action to prevent the development of resistance.

Concurrently, STK Stockton continues to invest heavily in its new technology pipeline with the intention of bringing more innovative biopesticides into different markets. As part of these efforts, the company has recently announced the appointment of Shay Shaanan as the new vice president R&D, leading the company’s activities. The former global development manager of the fungicides division at ADAMA (formerly Makhteshim Agan), Shaanan has over 15 years of experience in research and commercialization of crop protection products.

“Having Shay join our team marks another significant milestone in our growth strategy. It reflects our commitment to advance our technologies and provide the agriculture industry with new solutions for sustainable agriculture.” explained Guy Elitzur, CEO of STK Stockton. “Shay will lead our R&D and will be of enormous value in moving our company forward. Additionally, we will be looking for in-licensing partners, including bio companies in the U.S. to broaden our product offerings.” said Elitzur.

The products of Stockton will be sold under the Syngenta brand for Botrytis and Powdery Mildew in ornamentals globally. The biofungicide technology complements the comprehensive fungicide portfolio of Syngenta and will help to provide its customers with innovative sustainable tools for disease resistance management.

“We are very excited about this agreement,” Elitzur commented, “as Syngenta is the perfect partner for our new products in ornamentals.”

Postharvest Short Course Focused on Taste and Quality

UC Davis Postharvest Course Covers Food Loss, Produce Handling

By Lauren Dutra, Associate Editor

The 38th annual Postharvest Technology of Horticultural Crops Short Course concluded TODAY, June 24 at UC Davis. Presented by Beth Mitcham, director of the Postharvest Technology Center, the course focused on postharvest produce quality and safety.

Beth Mitcham, Director of the Postharvest Technology Center at UC Davis.

“This class provided a really broad overview of all the topics that are relevant for postharvest handling of produce, including fruits, vegetables, nuts, and also ornamentals,” said Mitcham. “We cover the crops that are grown in California, but because our audience includes a lot of people from around the world who want to learn the basics about postharvest handling, we also cover a few crops that aren’t grown in California for commercial purposes. Furthermore,”she noted, “we also address some of the latest technologies that are available for maintaining excellent quality,”

Maintaining a good cold chain throughout the entire shipping line is critical, according to Mitcham. “We talk a lot about temperature,” she elaborated. “In fact, we tell students the three most important things about postharvest biology and technology are: temperature, temperature and temperature. We discussed many other technologies during the week, but they are secondary to good temperature management,” she noted.

Mitcham also mentioned food waste and how to control it. “So much effort goes into growing the crop, which includes harvesting at the prime of ripeness and getting it in the pre-cooler, on the trucks and to the market. But, people buy it, put it in their refrigerator and then don’t eat it. It goes bad and they waste it. It does happen,” said Mitcham. “Our goal is to try to make the product as hearty as possible while retaining really good flavor so it can last in your refrigerator as long as possible but also so people want to eat it, so hopefully it doesn’t sit in there and degrade.”

In reducing postharvest losses, Mitcham commented on the dissonance between addressing postharvest flavor and consumer satisfaction, “In some ways they are two opposite ends of the spectrum; some of the things we do to reduce losses are counter to delivering good flavor to consumers,” she said. “We really need to do both, and that was a big part of our message this week.”

Also at the event, the California Leafy Green Marketing Agreement (LGMA) discussed food safety principles, and Trevor Suslow, a UC Davis Plant Pathologist with the Postharvest Technology Center, discussed good agricultural practices (GAP) for food safety.

Downey Mildew Continues to Challenge Leafy Greens

Downey Mildew Continues to Threaten Lettuce and Spinach

By Patrick Cavanaugh, Farm Director

One of the many facets that makes California Agriculture so successful is the hard-working group of farm advisors who assist growers with a multitude of plant and pest issues. Steve Koike, plant pathology farm advisor for UC Division of Agriculture and Natural Resources, Cooperative Extension in Monterey County, noted, “It has been a fairly typical year, and I wouldn’t say any particular new disease has been noteworthy, which is good for the growers.”

Steve Koike, farm advisor of UC ANR Cooperative Extension, Monterey County.

Koike, whose research focuses primarily on understanding disease systems, identifying new diseases and examining new methods of disease control, said growers “don’t like to see new diseases come out of our work. The main concern, downey mildew, continues to be challenging for both lettuce and spinach growers.”

“We started in the early spring with heavy mildew on both lettuce and spinach crops,” explained Koike, “and it’s remained pretty heavy on lettuce throughout the spring and early summer here. Spinach downey mildew goes up and down, which is not unusual.” he said. “We had some heavy mildew weeks for spinach growers, then we didn’t hear anything, then we heard that it had died down, and then ten days ago there was another surge. It’s one of those things that is hard to predict because it is variable.”

Since starting his farm advising position in 1989, Koike has been involved in educational programs and applied research in vegetable, fruit and ornamental crop diseases. Because downey mildew can overwinter in perennial crops, its continued occurrence is not too surprising.

“Earlier this year, Jim Correll, my cooperator at University of Arkansas, other leaders in the industry and I finally did confirm race 16, a new biotype of downey mildew. A few years ago, it was only race 12; it is moving target,” he noted.

“Although we have confirmed Race 16 on spinach, we are a little concerned because there are reports of disease on some race 16-resistant varieties.” Koike said.

Food Safety: Protecting Consumers, Protecting Brands

The Acheson Group Lends Commodity Groups Food Safety-Based Brand Protection

By Patrick Cavanaugh, Farm News Director

Dr. David Acheson, Founder and CEO of The Acheson Group

With the overall importance of food safety, it’s important that growers remain diligent in the enforcement of their food safety protocols. Dr. David Acheson is the Founder and CEO of The Acheson Group; a consulting firm for food and beverage companies as well as those who provide technical support to the food industry.

He noted that part of risk management is taking the particular commodity into account. Things like leafy greens and cilantro are examples of some of the more high-risk crops. One method of mitigating the risks involved is through the adoption of good agricultural practices. “That gets back to everything from controlling the quality of water that you’re using to irrigate, especially if its spray irrigation,” said Acheson.

Some other ways of lowering risk include making sure the equipment that’s being used is properly sanitized, checking for animal encroachment, as well as being mindful of the time it takes to get the product refrigerated after its been harvested. Acheson noted that, “as soon as you chop it out of the ground, you’ve got exposed surfaces and you’ve got pathogens where bugs can grow.”

Another area of vulnerability is making sure employees follow the established food safety protocols. Acheson said that when his firm is assessing the risk of an operation, “We’re always looking for, not only are you talking the talk, but are you walking the walk.” Safety means relying on people to follow procedure, “Most companies have good policies and procedures written but do they translate in the fields? To the way the workers are operating?” Acheson said.

Ensuring that all of the safety measures come together in a coherent and effective way is the cornerstone to a successful agricultural operation. Acheson noted that, “The good operations, they’re going to walk the fields just before they harvest to look for any evidence of obvious animal encroachment and are continuing to watch as they move down through the field harvesting the product.”

Flags in the field mean “Stop Harvest Here”

One way the USDA has tried to limit the risk involved in one particular crop was through the adoption of the California Leafy Green Products Handler Marketing Agreement. “I think it was a great step forward,” said Acheson. “I mean, really what it was doing was codifying good agricultural practices in California.”

The agreement has been so successful; it was used as a template for the FDA’s Produce Safety rule. By codifying good agricultural practices through the leafy green agreement, the FDA has taken it a step further with their increased area of jurisdiction. The “FDA has got global jurisdiction over leafy greens and produce that’s grown anywhere in the world that’s coming into commerce in the US,” said Acheson. “If you’re growing spinach in Salinas, or you’re growing spinach in Mexico, or anywhere in the world and you’re bringing it into the US to go into interstate commerce, you are required to follow the produce rule.”

Food safety is of great importance to farming operations of all sizes. “To me, no food company is too small to pay attention to food safety, they can’t.” said Acheson. He also noted that enforcement of safe handling practices is what sets some operations apart from others.

Acheson said, “That’s where you start to see the difference between the good ones and the not so good ones. Because the good ones will say, ‘this is a priority, we need to stop harvesting the rest of this field. It’s maybe 10 acres, but we’ve got to plow it under because we’ve got risks that we can’t control.’” Acheson continued, “That’s where you differentiate from the ones who will say, “well there’s ten acres, maybe we can use 9 of those acres and we’ll just plow under one acre of it.”

It all comes down to being diligent in the adherence to food safety directives. While it can sometimes be challenging for growers to always strictly abide by healthy agricultural practices, the alternative of being lax in enforcement could create dire consequences for not just an individual grower, but an entire commodity group.

VIDEO: Other Stressors, Not Pumps, Leading to Delta Smelt Decline

VIDEO: Wasted Freshwater in Failed Attempt to Save Delta Smelt and Salmon

By Laurie Greene, Editor

“Other Stressors, Not Pumps, Leading to Delta Smelt Decline,” a video produced by Western Growers, explains why the communities, business, and farmland in the Central Valley and southward still experience regulatory water cutbacks that are extreme in some cases, while 3 billion gallons of extra freshwater flow out to sea in the failing effort to save the Delta Smelt from extinction.

The VIDEO addresses this loss of freshwater unused by California residents and businesses still suffering from both drought conditions and environmental water cutbacks and that could have gone into water storage.

Western Growers accuses government agencies in charge of managing California’s water of restricting the Delta pumps far beyond what is required by the law. “As a result,” the association said, “billions of gallons of El Niño water have been flushed out to sea. Shutting down the pumps has not helped the Delta smelt and salmon recover, and government regulators are ignoring other stressors such as predation, invasive species and wastewater discharges.”

Drone Technology Benefits Agriculture

Drone Technology Useful for Calif. Ranchers and Growers

by Laurie Greene, Editor

Fifth-generation Parkfield rancher in southern Monterey County and 2016 Vice President of the National Cattlemen’s Beef Association, Kevin Kester, was introduced to the viability of potentially beneficial uses of owning and using a drone on his ranch for agricultural purposes.

Yamaha Drone

As owner and operator of Bear Valley Ranch & Vineyards, the family’s cattle and winegrape operations, Kester anticipated the biggest benefits of drone ownership would be the capability to check on cattle and ensure their safety from a bird’s eye view, and to determine water levels in reservoirs—a task that in the past could be completed only on foot or by vehicle. Cattle safety is especially important for ranchers, according to Kester, as the cattle industry has been experiencing stagnation in production.

Kester said having a drone would also helpful for security issues. He wants to detect human intrusion on his land, a problem that he experienced recently. “There have been some hunter-related trespass issues and people coming onto the ranch,” he said. “We’ve actually had cattle and horses shot.”

Kester, who is also a member of the California Association of Winegrape Growers, Paso Robles Wine Country Alliance and the Central Coast Vineyard Team, will purchase a commercial drone package and believes this modern technology will give not only cattlemen, but growers in California, a new way of assessing safety, production and maintenance.

Dry Weather Affecting Cattle Ranchers

Cattle Ranchers Hit Hard in the South Valley, Move to Greener Pastures

by Emily McKay Johnson, Associate Editor

Josh Davy, a University of California, Division of Agriculture and Natural Resources, Cooperative Extension livestock, range and natural resources advisor in Tehama County reported good news for the cattle industry despite dry weather conditions around the state.

Heading into last fall, the feed year started off relatively dry, according to Davy; however the end-of-season crops produced a better forage than the year before. Though prices slid for the cattle farmer, Davy said optimisticly, “We’re happier on our range conditions—as compared to the previous years that we’ve had—by a long shot.” he said.

The drought that plagues California still directly impacts cattle ranges, and ranchers are not quite out of trouble. Davy had to resort to feed supplementation through the month of December. “We didn’t have to supplement as much as in the previous few years,” he said, “but we definitely did this fall.” Fortunately the winter months were short and the spring rainfall produced good growth—good assurances that will help Davy and his team make it through next year.

Davy has fortunately sidestepped hardship with a tinge of luck, but it hasn’t been as easy for ranchers in the south of the state. When cattle lack enough sustenance, a domino effect is felt all across the state of California; a lactating cow may not produce enough milk to feed her calves.

The cows like lush grass, a rarity in the Central and South Valley summer months. Winter options for cattle are either winter range ground or mountain meadow ground where greenery is still prevalent. Some ranchers haul their cattle to summer pasture feedlots to graze, while some prefer Oregon instead.

“We’re dried off here to where you might find a swell with a little rye grass in it that’s still green,”Davy said regarding the disappearance of lush land, “but pretty much everything else, the oats and all that stuff, they’re done here.”

Looking forward, Josh Davy is hoping irrigation water will sustain not only the beef cattle, but the pastures as well, to keep the herds stationary and munching on green grass.

The Fight Against the Asian Citrus Psyllid

California Citrus Mutual on the Fight Against the Asian Citrus Psyllid and HLB

By Laurie Greene, Editor

On Saturday, June 4, 2016, Patrick Cavanaugh, California Ag Today’s farm news director, hosted iHeart Media’s Ag Life Weekend show on “Power Talk 96.7 FM Fresno and 1400 AM Visalia stations, sitting in for broadcaster Rich Rodriguez. Cavanaugh’s invited guests included Alyssa Houtby, director of public affairs, and Chris Stambach, director of industry relations for the Exeter-based California Citrus Mutual, to discuss the status of the state’s citrus industry amidst the ACP and HLB Infestation.

The Asian Citrus Psyllid (ACP), certainly the number one pest for California citrus, can spread a bacterium known as Huanglongbing (HLB) that is fatal to citrus trees. As of 2016, 22 trees in the state have been infected with the fatal disease and had to be destroyed. The entire citrus industry of California has been and continues to be concerned that the ACP could take down the citrus industry, as it has in Florida.

Alyssa Houtby explained that the fight against ACP in California “is going well, we hope. The Florida citrus industry has been completely decimated by HLB; an estimated 90 percent of their acreage is infested with this disease.”

“Here in California,” Houtby continued, “we saw it crop up in residential citrus before we saw it in commercial citrus. All of the HLB finds, to date, have been in the Los Angeles Basin.” Houtby said they are working diligently to keep the psyllid population down to decrease the exposure of trees to HLB.

The California citrus industry spends approximately $15 million annually on an ACP assessment program, which includes extensive public outreach. Part of the research entails trapping the pest, conducting survey work in the regions in question, applying treatments in residential areas, and managing a delimitation survey around the area of Los Angeles where the disease has populated.

“That means that we’re scouting very consistently,” explained Houtby, “looking for other trees with the disease and pulling those trees out as soon as we find them. We are doing everything we can here in California to keep the pest and disease from spreading—now that we have it,” she noted.

Alyssa Houtby, director of public affairs, California Citrus Mutual

“The California industry has always been one to use a proactive approach,” Houtby elaborated. “We saw what happened in Florida, and we realized really early on that we couldn’t stand by and wait for this disease to find us. We had to actively go look for it and find it—before it found commercial citrus—and we’ve done that.” Regarding the 22 trees in the state that have been destroyed thus far, Houtby said, “It could be a lot worse if we weren’t as proactive as we are.”

When locating a positive ACP find in a residential area, Houtby noted, generally speaking, homeowners have mostly been compliant. “There are pockets in this state where folks don’t like government coming in, knocking on their door and asking to spray their trees with pesticides. We understand that. It’s an opt-in/opt-out scenario here. We’re not forcing homeowners in most cases to treat their trees.”

Chris Stambach, director of industry relations for California Citrus Mutual

“But that’s a different situation if HLB is present,” she emphasized. “Then we do. We get a warrant, and we go in and treat the surrounding trees. If we’re treating in response to an ACP find, homeowners can opt out, but overwhelmingly, they don’t. They support our program. They understand that citrus is a part of the California heritage, they like their citrus trees, and they want to keep them in their yards. They understand that the alternative to not treating is that tree will eventually die if it becomes infected. We’ve worked really hard to communicate to the general public about the seriousness of this issue. We’re pleased with the results.” Houtby said.

Chris Stambach discussed the importance of homeowners having a general understanding of the ACP, so if they find something unusual in their citrus tree, they know to call the local ag commissioner.

Stambach detailed ACP and HLB specifications to increase homeowners’ understanding about their beloved citrus trees. “HLB is symptomatic, but it takes a long time for those symptoms to show up in the tree,” said Stambach. “You really have to know what you’re looking for because some fertilizer deficiency issues in the tree will mimic what HLB looks like.”

“Though the ACP is a really tiny little bug, there are some key signs the public can look for,” explained Stambach. “You want to look for that psyllid and the little tubules it excretes on the new flush of growth—pretty much right there at the end of the terminals where all that new growth comes in the springtime and in the fall. That’s key to California, because there are only certain times of the year when that ACP is actively feeding on the citrus tree.”

California has a real benefit over the Sunshine State, where they have to spray 12 times a year to keep the psyllids at bay. “It hasn’t been effective for [Florida],” noted Stambach. “We had a couple of growers out this last winter to our Citrus Showcase. They planted new trees, 4 years old, and although they spray 12 times a year, their orchards are 100% infected with HLB. That’s the devastation that this insidious disease can bring. It’s really difficult to get your hands around it because it takes so long to be able to detect it.”

Another benefit for California citrus, according to Houtby, is, “We have a lot of areas in the state where we don’t have to spray at all because we can use beneficial insects. That’s just the great part about farming in California.”

Houtby and her team often look to Florida for ideas and recommendations on what has worked for them, what hasn’t and what citrus growers here can do to prevent the disease from taking hold of their citrus. She clarified that 90 percent of the Florida citrus market is used for juice production; whereas, California is a “fresh-oriented industry, meaning that over 90 percent of our product goes into the fresh market.”

Although California citrus looks for recommendations from Florida, “here in California, there are a lot of things that we can’t afford to do because of the [fresh] market that we’re serving,” said Houtby.” That is what we’re fighting so hard to maintain because we cannot sustain as long as Florida has; we don’t have the luxury of sending a bad-looking piece of fruit into the marketplace like Florida can, because they just juice it. Knowing that, we’re working really hard to never get to the point that Florida has reached.”

As if the dire situation in Florida couldn’t be any worse, they battled with “another deadly bacterial-based citrus disease, citrus canker, brought in from the far reaches of the world,” Stambach said. “That’s a concern we always have with importing citrus. When we import Argentine lemons, for example, we risk our domestic plant health by exposing orchards to a lot of plant diseases they have that we don’t. We want to keep those out of our country,” noted Stambach.

Abandoned citrus trees also pose problems for the industry; they can be sanctuaries for ACP. “If those trees are dead, that’s not a problem. They may look bad, but if they are not living, that’s not a problem. It’s when those trees aren’t cared for, aren’t sprayed in a normal routine, and there is a flush of new growth, the trees provide a sanctuary for the psyllids,” he said.

Abandoned Citrus

“And ACP are very good at finding citrus. They’ll target the perimeters of new growth on the very first citrus they find. Boom, they’re right on it,” he noted.

“Those abandoned groves create a real problem, particularly when they’re in close proximity to other commercial acreage or even homeowners,” he said. Neglected neighborhood citrus trees can become ACP sanctuaries. “ACPs will feed on them and move on to another tree, and feed there,” Stambach explained. “All that time, if an ACP is infected with the HLB bacteria, it will spread that disease, with a latency period of 2 to 5 years.”

Stambach and his team are working on a critical program in Southern California to remove abandoned citrus trees. “Sometimes it’s just getting a hold of the landowner and making them aware of the situation,” he said. “Our county ag commissioners are really key in contacting those people. We’ve had growers go in and spray their neighbor’s orchard to help them out. There are a lot of different ways to attack that problem.”

Compared to counties in the San Joaquin Valley, Riverside and Ventura Counties typically have a big-ag urban interface, which means there is a lot of acreage intermixed with home sites—small homes with citrus trees. Stambach said, “It’s not really commercial production, but it’s a significant amount of acreage with a number of trees that don’t get treated.”

“We’ve gotten some support from some of our partners in the chemical industry. Bayer CropScience has stepped up and worked with us to put together a program. We’re really happy. We’re working hard to take [ACP and HLB] out.” Stambach said.

“Fresno has even found ACPs in residential areas,” commented Houtby on the Central Valley situation. “ACPs are endemic in Southern California, but we’re still at a point in the Central Valley at which we can control these populations and knock them down really quickly when they arrive here.”

Houtby points to the Central Valley’s vulnerability when citrus plant material is moved over the grapevine or from the Central Coast. “We ask that homeowners, and the citrus industry as well, not move plant material out of Southern California into the Central Valley,” she stated. “The psyllid lives on that plant material and not on the fruit. If you’re going to buy a citrus tree, buy it at a local plant nursery or a local Home Depot or Lowe’s. Don’t buy it in Southern California and drive it to the Central San Joaquin Valley,” she urged.

“Our biggest task for homeowners is that they cooperate when the California Department of Food and Agriculture knocks on the door and wants to look at their trees,” Stambach said. “That is the best way you can help us win this battle against the ACP.”

RAIN Damages Alfalfa; Benefits Wheat

Above-Average California Rain Affects Larry Hunn’s Crops

by Emily McKay Johnson, Associate Editor

For fourth-generation farmer Larry Hunn of Hunn & Merwin & Merwin, Inc., based out of Clarksburg, Calif., the price of alfalfa is low this year due to water damage from late rains. Nevertheless, cannery tomatoes, cucumbers, safflower and wheat are looking pretty hopeful.

Larry Hunn

Mold from rainfall is a big issue in growing alfalfa; it not only reduces the quality of the perennial grass, but it reduces the nutritional value as well. Dairy farmers won’t buy it. “It has really depressed our alfalfa prices.” said Hunn.

On the bright side, rainfall has been beneficial for Hunn’s above-average winter wheat and safflower crops this year. “We had nice rainfall spread out through the whole winter,” he said. “It didn’t come all at one time and flood us out, so that was good.”

Hunn’s hard red winter wheat is drying down in the field, and will be harvested mid-June and sent mainly to flour mills for bread making. The safflower is still growing and looking healthy on a few hundred acres—acres that have been in his family for four generations—and won’t “come off” until late August or September.

Beginning in South Sacramento on 47^th Avenue, Larry Hunn’s great-grandfather started farming in the late 1800s, and his grandfather moved to the Delta in the early 1920s, where they’ve been farming ever since. Hunn & Merwin & Merwin Inc. now operates on close to 3,000 acres in Yolo and Sacramento Counties.

Hunn’s other crops have already been contracted with a buyer. “All the cannery tomatoes are in the ground growing, and they look pretty good. We’re in the process of planting cucumbers, that’s just a continuous until the first of August,” mentioned Hunn.

The only disadvantage are the cool breezes from snow atop the Sierra Mountain range that is keeping temperatures low on the cucumbers and tomatoes. Hunn remarked, “I wish it would warm up a little bit. We’re only in the mid-seventies, low eighties, and it would be nice to be up in the mid-eighties or low nineties.”

Overall it’s been a decent year for the veteran Clarksburg grower.

It’s Avocado Month!

Celebrate the Magic of California Avocados.

By Emily McKay Johnson, Associate Editor

Chefs and foodies alike, get ready for California Avocado Month which begins TODAY, June 1st. Menus across California are celebrating this magical fruit, not only for its postive health benefits as a source of Omega-3 and Vitamin E, but also for its resiliency to thrive in spite of the prolonged drought.

“Avocados are at their peak of the season,” said Jan DeLyser, vice president of marketing for the California Avocado Commission (CAC), “so we’re in very good supply and their eating quality is just second to none.”

Avocados are so diverse, they can be incorporated into daily menus for breakfast, lunch, dinner, snacks, beverages and even desserts. Consider celebrating summer gatherings with chocolate avocado pudding, avocado ice cream or, perhaps, even an avocado cake. Links to recipes are included at the end of the article.

Would you believe California avocados can be used as a butter alternative—with 300 fewer calories per quarter cup serving?

Despite entering year five of the drought, California and its farming industry received enough rain in the northern part of the state this year to replenish reservoirs and actually increase this year’s avocado harvest. Roughly 4,000 growers on approximately 53,000 acres have harvested 392 million pounds of avocados.

“We actually have more fruit this year than we had last year,” acknowledged DeLyser. “Our growers are continuing to be good stewards of the resources that are available to them and able to produce avocados for us all to enjoy throughout the summer months.”

The CAC’s collaboration with chefs around the country to feature California avocado items, helps support growers of the tree-bearing fruit in the state. Approximately 90 percent of the nation’s avocado crop comes from fertile, California soil, mostly on small family farms, which can ensure the avocados are carefully handled and inspected.
