Indianapolis, Indiana (May 8, 2012)--With previously standard control methods like Temik, seed treatments and organophosphates either unavailable or ineffective, cotton growers need a tool to manage thrips. RADIANT® SC insecticide, a standard for thrips control in hundreds of crops, offers growers an effective option for early season management of western flower and tobacco thrips in cotton grown in states throughout the Cotton Belt.
Thrips were one of the industry’s most devastating pests in 2011, according to a presentation given by Michael Williams, Extension entomologist emeritus at Mississippi State University. Williams presented research at the 2012 Beltwide Cotton Conferences showing thrips infested 83 percent of all cotton acreage and resulted in a yield loss of 0.695 percent, the second-highest loss due to an insect.
“Cotton growers are all too familiar with the damage thrips can inflict on a crop,” says Brian Timmerman, portfolio marketing leader for insecticides for Dow AgroSciences.
Enter RADIANT, which received a 2(ee) recommendation that extends to cotton grown throughout Alabama, Arkansas, Georgia, Louisiana, Mississippi, Missouri, North Carolina, South Carolina, Tennessee and Virginia. The 2(ee) recommendation was expanded in February to include all counties in Texas except Cameron, Frio, Hidalgo, Medina, Starr, Uvalde, Willacy and Zavala.
Roger Carter, president and co-owner of Agricultural Management Services Inc. in Clayton, La., says 2011 was an especially bad year for thrips.
“Thrips damage to cotton in 2011 was more severe than we have observed in many years,” Carter says. “Western flower thrips was the predominant species and was uncontrolled with the standard organophosphate insecticides.”
In a summary of 17 trials across the Cotton Belt, applications of RADIANT at 1.5 oz./A with an adjuvant showed superior control of thrips compared with Orthene 90S. RADIANT also has a low impact on most beneficials and will not flare aphids or mites. This attribute can save growers time and money on additional sprays that can result from applications of organophosphates that flare those insects.
Carter recommends growers apply RADIANT if they have had economically damaging injury to their crop.
“Our clients recognized that the current standards would not control western flower thrips and that, if they wanted management of thrips, RADIANT was the answer,” Carter says. “RADIANT managed western flower thrips very well.”
RADIANT® SC insecticide is a unique Group 5 insecticide, a classification that makes it an ideal fit in an Integrated Pest Management program. It was registered under the Reduced Risk Pesticide Initiative of the U.S. Environmental Protection Agency and received the Presidential Green Chemistry Challenge Award.
“RADIANT has proven to be an industry leader in controlling thrips and would be a valuable addition to any thrips management program,” Timmerman says.
Early season, foliar applications of RADIANT should be made only to fields that have already received an insecticide seed treatment.
