Valent Announces Biological Seed Treatment for SCN

Aveo EZ Nematicide to help protect soybeans from yield loss caused by soybean cyst nematode.

Valent announced today the launch of new Aveo EZ nematicide to help protect soybeans from yield loss caused by soybean cyst nematode (SCN), reniform nematode and more. SCN is a microscopic roundworm that’s the soybean industry’s biggest yield robber.

Aveo EZ is a biological seed protectant. It colonizes the roots of the soybean plant to reduce nematode reproduction. The highly concentrated formulation of Aveo EZ contains more colony forming units (cfu) per ml than competitive products, which means more powerful protection at a lower use rate (0.1 fl oz/140,000 seeds). According to Valent the formulation has a long shelf life.

Comprised of naturally-occurring microbes, Aveo EZ offers easy handling for seed treaters, requiring standard personal protection equipment, including a long-sleeved shirt, long pants, and protective gloves when handling treated seed.

SCN can cause 30% yield loss in soybeans without visual symptoms and they cause $1.2 billion damage annually.

In research trials in fields with known SCN infestations, Aveo EZ yielded an additional 1.83 bushels per acre when added to a base treatment, demonstrating stronger performance than competitive seed treatments. The performance and handling of Aveo EZ was put to the test in a 2017 national trial among retailers and growers. An overwhelming majority of retailers in the Midwest and the South saw greater than 90% seed coverage, under a wide range of cold and warm conditions when treated. Retailers consistently reported that the low use rate of Aveo EZ made it easy to mix and use with other seed treatment products. Growers also saw a greater rate of emergence with Aveo EZ compared to the competitive plots.

Available as a stand-alone product, Aveo EZ gives retailers flexibility to optimize the ratio of nematicide to fungicide and insecticide protection in soybeans.  Seed treaters can easily add SCN protection to a base seed treatment of Intego Suite soybeans, with minimal adjustment to the treater settings.  

“Aveo EZ is a new, user-friendly nematicide that offers convenience for retailers and performance for growers,” says Thad Haes, seed protection business manager for Valent. “We anticipate that the low use rate will create a real benefit for retailers who apply multiple products to the seed and want to achieve quality seed coverage that delivers yield-enhancing performance for their growers.”  

SCN is a significant yield-robbing pathogen that is not obvious at the time of initial infestation, but can be found in almost every soybean field, says Todd Mayhew, seed protection product development manager at Valent. “In some areas of the U.S., SCN is not perceived as a problem because growers have relied on SCN-resistant soybean varieties,” says Mayhew. “However, with SCN developing the ability to reproduce on these varieties, an integrated approach, including a nematicide such as Aveo EZ, is vital for effective management.”

“Aveo EZ complements our growing line of seed protection solutions, including Intego Suite soybeans,” says Haes. “At Valent, we are investing in proprietary, below-ground technology to help growers protect their crop from disease, insects, and nematodes and optimize its health through water and nutrient-management solutions.”
