The Environmental Protection Agency (EPA) has granted a Section 18 exemption of the Federal Insecticide, Fungicide and Rodenticide Act to the Texas Department of Agriculture for the continued use of Topguard fungicide for cotton root rot control.
This emergency use is effective February 1, 2014 and expires on June 30, 2014.
This means for the third consecutive year, Texas cotton growers can use Topguard to manage cotton root rot, a devastating disease that is estimated to cause direct yield losses of as much as $40 million annually.
“Since the 2012 growing season, the EPA has granted this emergency use for cotton growers in Texas,” said Deneen Sebastian, director of marketing, Cheminova, Inc. “Topguard, with the active ingredient flutriafol, is the only fungicide known to protect cotton plants from cotton root rot.”
Topguard may be applied at planting either as a T-Band application or modified in-furrow.
For T-Band, Topguard should be applied in a concentrated three- to four-inch wide band at planting, perpendicular to row direction after furrow opening and seed placement, but prior to furrow closure.
For modified in-furrow, Topguard should be applied using a splitter/Y-shaped application mechanism or seed firmer that directs the product on the sides of the seed furrow and not in direct contact with the seed.
Growers who apply Topguard for cotton root rot must have a copy of the Topguard Fungicide Section 18 Exemption label on hand during application.
