The Environmental Protection Agency (EPA) has granted a Section 18 exemption of the Federal Insecticide, Fungicide and Rodenticide Act to the Arizona Department of Agriculture and the Oklahoma Department of Agriculture, Food and Forestry for the use of Topguard fungicide for cotton root rot control.
In Arizona, this emergency use began April 14 and expires on June 15, 2014. In Oklahoma, the emergency use also began on April 14 and expires on June 30, 2014.
“Topguard is the only fungicide known to protect cotton plants from cotton root rot, and the EPA has granted this emergency use for cotton growers in Texas for the past three years,” said Deneen Sebastian, director of marketing, Cheminova, Inc. “Cheminova is glad to see growers in Arizona and Oklahoma also receive this exemption to provide them greater success in managing this disease.”
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. Growers in Arizona must also complete an application for a Section 18 permit.
