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.

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.”

timorexgold STK Stockton Group“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.”

CAPCA’s Terry Stark: Biopesticides More Mainstream

Stark Speaks About CAPCA and its Role in the Biopesticide Industry.

By Patrick Cavanaugh, Editor

 

Terry Stark, President and CEO of California Association of Pest Control Advisors (CAPCA,) told 140 attendees at the Biopesticide Industry Alliance semi-annual early April meeting in Sacramento, what his organization thinks about the softer pest and disease control products.

“CAPCA represents 3,000 members of the 4,000 licensed-PCAs in California.

We have expanded our educational outreach through CAPCA-ED. We run 40 seminars annually throughout the state to aid all license-holders to improve their categories,” Stark announced,” said Stark.

“The regulatory burden pushes us to be better and more advanced,” Stark said. “CAPCA has 16 chapters, and each chapter has a director seated on the state board. My Chairman of the board is Jeremy Briscoe a Certis USA national manager. So I believe CAPCA is very well integrated with the biopesticide industry. Jeremy is the first representative that is a non-retail, non-independent to serve as the chair of CAPCA. This is a big move in the mentality of what we do,” said Stark.

CAPCA has traditionally centered on the San Joaquin Valley – production agriculture – the heart and soul of diversified agriculture and the money. “However, in the last 10 years, the wine industry has taken a step higher than the our other crops. All of a sudden we have Napa, Sonoma, Paso Robles, and southward to Santa Maria and Ventura County.”

Stark explained that everything west of I-5 tended to be the “softer side” of PCAs and chemical use in California. “I say that with respect because the wine industry was looking for ways to use less conventional products, ways to brand both organically and sustainability and with lower tolerances for their products. That caught on solidly seven or eight years ago.” Stark continued, “My largest independent PCAs are between Mendocino and San Francisco.”

“Like my Ventura guys and gals, they use more biological controls by releasing a lot of beneficials,” said Stark. “And it’s hard to come in with a hard-core application and maintain your beneficial populations,” he said.

When Stark was asked to speak at the Biopesticide Alliance meeting, he was asked to talk about perceptions. “I reflected on what I saw as a manager when they hired me to come to CAPCA. You talk about perception of biopesticides, with all due respect to my membership, 30 percent think that it’s one way or the highway.

In the central part of the state, from Kern County and throughout the desert valleys, it’s still spray and run. It’s big business, big acres. But it has its place,” said Stark.

He spoke about California being a hodgepodge of the most invasive species in the world, with many new pests coming in seemingly every week.

“Our entire citrus industry is facing Asian Citrus Psyllid which vectors the deadly citrus greening disease; we just survived the Glassy-winged sharpshooters in the wine industry; and, we’ve got Shot-hole bores coming to avocados. This represents huge production areas,” he said.

CAPCA has recognized that there are new ideas in pest and disease control and has moved towards being able to incorporate other chemistries, pheromones, and other items into the tool chest.

 

CAPCA’s Aging Demographics

Stark shared some demographics of CAPCA. “In CAPCA meetings, I don’t see a lot of dark-haired people sitting in the room. I don’t see a lot of females sitting in the room.

Our gender is 10-15 percent females,” he said.

Seventy five percent of my membership has 16-plus years of experience as PCAs. CAPCA also manages 1,000 Certified Crop Advisor (CCAs) who focus on nutrient recommendations, and the same demographics carry over to them. Of that, 35 percent have 30-plus years of experience. Do you think many will work past 30 years?

CAPCA’s last membership survey was done in 2010. We are projecting a 20% loss of membership by 2015. And that continues outward in a five-year cycle.

Through the Department of Pest Regulations we are only testing maybe 12-15 percent maximum replacements with young PCAs coming into the cycle.

How do we survive? We are turning to electronics, iPhones, and iPads.

PCAs have to be licensed in California if you are using restricted-use materials, soliciting for sale, and/or acting as an expert thereof. That takes care of the whole sales group too.

So, in biopesticides, you’re outside of that umbrella in most ways. You have some products that you to play with, but overall, that gives a “softer approach” for the younger PCAs to look at.

 

 Working Areas of PCAs

Sixteen percent of PCAs work in field and row crops; 34 percent in trees & vines, the only ones getting water this year; vegetables at 12 percent; and turf and ornamentals –10 percent. Turf and ornamentals in California drop 50 percent in the last 5 years with the collapse of the housing and commercial real estate industries, plus golf courses, they have had a pullback. So our members have moved to retail and other areas.

If you are in PAC and you are in retail, you represent 30 percent of the industry. Eighteen percent are independents, and that means you truly do your own thing: if you have alfalfa, you have 20,000 acres you’re looking at; if you have citrus, you’ve got 3-5,000 acres; if you have vineyards, you’d better have 2-3000 acres to pay for it—if you want to make big money—and you’re working 7 days a week to do that. Seventeen percent are in-house; these are the Paramount’s and the Boswells of the industry. They hire CCAs and PCAs like full-time employee of the ranch.

The dynamics of I-5 is not moving into the Central Valley or into the southern counties. You have pockets of Los Angeles and Santa Barbara where you have nursery stocks, that‘s always been kind of open to the biopesticides industry and its products.

What I think has made the biopesticide industry successful, beyond all of your research, hard work and marketing, are the opportunities and the new wave of using your thumbs, and twitter, and communications, and Facebook, and social media in general. The outreach that you can do your business on the iPhone and still drive down the road, answering your clients’ questions has enabled the “boutique” industry in the last 5 years to come closer to the mainstream because customers don’t have to do any special work to find out about you. You are in their feed lines of information. These are important tools,” said Stark.

“California is a highly-regulated environment, so electronics has complemented other resources. I think the known fact that many products are less toxic is a huge benefactor,” he said.

“Take the Light Brown Apple Moth, which ended up being a environmental community PR campaign that kicked food and agriculture’s butt in California. And now every fruit tree in Santa Cruz is going to die from the apple moth. You can’t even move the firewood because it will contaminate the rest of the area,” Stark said.

The unknown elements of a pheromone to treat the moth were a big problem because the public did not understand, and the industry took it for granted. “The pheromone is about as soft and appropriate as you can get in the marketplace,” said Stark. “But we need to approach the public in a different way. And I think the biopesticide industry is doing a much better job,” he said.

“I’d be remiss with all of the large companies sitting in the room, the BASF’s, Syngenta’s, Bayer’s, the Valent’s—all have learned to adopt and bring into their tool chest additional products that can complement their conventional materials and usually make the grower more profit,” noted Stark.

“CAPCA doesn’t get into this much, but we have a lot regulatory obligation responsibility to protect the field worker. The toxicity and the life of the product go a long way in how you get back into the field,” he said.

“So, in the biopesticide world, you have a better opportunity of targeting the exact pest you need to target. It’s not a broad-spectrum-type deal. So that gives you the advantage. My PCAs see that– my 50 percent younger side in the house – sees that. And that’s a positive for this industry,” Stark said.

IPM is not a word that is understood until you get to California. CAPCA cannot do anything in his recommendation without being CEQA-oriented (California Environmental Quality Act) must look for alternative uses before any restrictive material can be made; otherwise he is in violation of his own recommendation. IPM, and biopesticide products fit that requirement to make that check mark when they do that.

“In addition, biologicals are lower priced than they ware 7-8 years ago. And that’s good because the grower doesn’t spend a dime more than they have to. If you think PCAs are out there pounding product or fertilizer on, and the farmer is not making any money, just three minutes later in the coffee shop, that guy is fired and another is hired,” Stark said.

“It is important to the sustainability in going forward, when you have a regulatory environment like we do in California. We have a built-in arena here and people are always listening to what can be done better and still make a profit. In my opinion, you are off to the races and biopesticides are mainstream now,” noted Stark.

If you can hit 15-20% of the marketplace, it’s been a great quarter-century run for you to get there and I think the CAPCA membership is looking forward to a long-lasting relationship.

He reminded attendees of the popular CAPCA Conference, Oct. 19-21, 2014 at the Disneyland Hotel in Anaheim. “I have 1,300 attendees and 150 exhibitors. What better place to be than with 800-900 license holders. It’s all relationships. Once you get the relationship, your social media, and your electronics, your product will sell itself,” Stark concluded.
