New active for seed treating pending registration
“We’ve seen the use of metalaxyl and mefenoxam increase substantially in recent years within seed treatments as the industry tries to cope with increased pythium and phytophthora pressure,” Robinson said. “Plant pathologists are still researching whether this indicates growing fungicide resistance, the emergence of new disease strains or both.”
Robinson added that it has been more than 30 years since metalaxyl, the most widely used tool for these diseases, was registered.
“Growers and seed professionals urgently need a new and effective tool against these escalating and emerging diseases, many of which evolve even over the course of the season. The currently available products simply are not providing the control these growers need,” Robinson said. “In current trials, AP3 is showing superior protection against the toughest diseases, which will help protect the seed and seedling in both early- and late-planted crops. And, research trials are showing AP3 has no known cross-resistance and offers exceptional seed and crop safety.”
Ethaboxam, the key active ingredient in AP3, is anticipated to be EPA registered on corn, soybeans, cereals, canola and sorghum crops with full seed and crop safety. Until ethaboxam is registered it can only be used by qualified research personnel for research purposes.
“AP3 looks to be a game changer for the industry, which is facing increasing disease pressure or resistance and uncertain growing conditions,” Robinson said. This will be the fifth major seed protectant in the Valent portfolio of products.
