Syngenta Crop Protection has received U.S. EPA approval for changes to the Touchdown Total and Touchdown HiTech glyphosate herbicide labels — changes that provide for maximum use rates, an added application and drop nozzle use with hybrids featuring Agrisure GT and Roundup Ready corn.
“The new changes to the Touchdown Total and Touchdown HiTech labels give growers the same flexibility on rates and timings with hybrids featuring the Agrisure GT trait as they have with RR 2 corn,” said Dan Hinderliter, Touchdown brand manager for Syngenta.
The maximum in-crop use rate was raised to 70 fluid ounces per acre for Touchdown Total and 1.8 quarts per acre for Touchdown HiTech. The maximum single application was increased to 35 fluid ounces per acre for Touchdown Total and 30 fluid ounces per acre for Touchdown HiTech. The labels were also revised to allow application of Touchdown brands to glyphosate-tolerant corn 30 inches to 48 inches tall using drop nozzles.
Prior to this revision, application with ground equipment only was approved for glyphosate-tolerant corn up to the V8 stage or 30 inches in height, whichever came first.
“Growers planting glyphosate-tolerant corn, including elite hybrids with Agrisure GT, in 2006 will be able to apply Touchdown Total or Touchdown HiTech over-the-top,” added Hinderliter. “They will be able to plant the glyphosate-tolerant corn hybrid they want and use the glyphosate herbicide they want.”
Touchdown potassium glyphosate brands, backed by support that includes the Touchdown Assurance Plan, deliver consistent, down-to-the-roots control of more than 170 grass and weed species in 230 crops. The Touchdown Assurance Plan helps growers protect their seed technology and crop investments.
A fully loaded formulation, Touchdown Total features IQ Technology — a unique corn-based adjuvant system — and patented Low Foam Technology for improved handling.
Touchdown HiTech, the most concentrated glyphosate available, is designed for growers who prefer to use surfactants and additives customized for their farming operation.
