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 new AVICTA brand seed treatment is a breakthrough in early-season pest
protection and a leading advancement in the development of seed treatment
solutions for corn growers,” said Mark Jirak, crop manager, Syngenta Seed Care.
“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.”
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. In fact, the majority of
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.
Southern growers have an advantage over the rest of the country because of their
long history with battling nematodes in cotton. They already know nematodes exist
and have experienced first-hand the destruction that can lead to yield loss and a
decline in profit. Most of the nematodes present in cotton fields, including two of
the most damaging nematodes in cotton production, the root-knot nematode and
lance nematode, also are threats to corn acreage.
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.
