EPA gives registration to first seed treatment nematicide for use on corn

Agriculture.com Staff 01/14/2009 @ 9:43am

An AVICTA brand seed treatment nematicide from Syngenta Seed Care recently was approved by the U.S. Environmental Protection Agency (EPA) for use on corn.

Syngenta Seed Care will offer the new AVICTA brand seed treatment nematicide in combination with an enhanced rate of Cruiser seed treatment insecticide and the most robust seed treatment fungicide package available (Apron XL, Maxim XL and Dynasty) to provide corn growers with complete early-season protection against nematodes, insects and diseases. AVICTA brand nematicide will be widely demonstrated in cooperation with seed companies in the form of large plot, on-farm plantings during the 2009 planting season, and will be launched commercially in 2010.

"The combination of an AVICTA brand, Cruiser and the Syngenta Seed Care corn fungicide package will be the only seed-delivered technology that offers growers triple protection against nematodes, insects and diseases," says Mark Jirak, Syngenta Seed Care crop manager.

Corn nematode populations have escalated in recent years due to changes in production practices. In the past, nematode damage was suppressed by the widespread use of in-furrow organophosphate and carbamate insecticides. Now, with the switch to pyrethroid insecticides and transgenic rootworm-resistant corn, nematode pressure may become more evident as these products lack the ability to suppress nematode populations. The increased trend in no-till farming may have helped provide an environment for nematodes to thrive because these pests are sensitive to soil disturbance. Also, corn-on-corn cropping, which has become more prevalent in the last few years, can also cause corn-damaging nematode numbers to build.

Many different species of nematodes live in U.S. corn fields. Most corn nematode species are native to the United States and were present before corn was even cultivated domestically. In 2007, Syngenta Seed Care initiated a survey of corn nematode populations throughout the Midwest. Surveyors took three random soil/root samples in each county of the Midwestern Corn Belt with at least 25,000 acres of corn. Five university labs and one private lab processed the samples and determined that corn-damaging nematodes were found in every county sampled.

Syngenta officials say an AVICTA brand seed treatment nematicide provides immediate protection against all major early-season nematode species, including root-knot, stubby-root, sting, dagger, ring, stunt, spiral, needle, lesion and lance nematodes. Providing effective nematode protection from the time the seed is planted promotes stronger stands and emergence, and builds the foundation for better yield and return on investment potential.
