Katagon®

Katagon® is a new postemergence herbicide for targeted control of broadleaf and grass weeds that is safe for use in different types of field corn.

For corn growers looking to get a grip on tough weeds, Katagon® is a powerful postemergence herbicide offering targeted control of broadleaf and grass weeds. This first-of-its-kind HPPD premix gives application flexibility, protects from yield-robbing threats and keeps fields clean. 

Katagon combines two proven active ingredients (tolpyralate and nicosulfuron) for   control of weed species including those resistant to glyphosate, PPO’s, triazines and ALS inhibitors. Katagon also offers a low use rate, user friendly profile and wide application window.

Primary Weeds Controlled

Waterhemp, Palmer Amaranth (amaranth spp.), Ragweed (common, giant), Barnyardgrass, Foxtails (giant, green, yellow), Lambsquarters, Ivyleaf Morningglory, Large Crabgrass, Redroot Pigweed, Sorghum, Velvetleaf, Venice Mallow

Application

  • Katagon is designed for early to mid-season postemergence applications. It is powerful enough for a one-pass postemergence program when tank mixed with atrazine for enhanced weed control.1 When used in a tank mix with atrazine, application must occur before corn reaches 12 inches high. 
  • With a wide application window, Katagon can be applied to corn from V1 up to 20-inch-tall corn or V5, whichever is most restrictive. 
  • In fields where tough-to-manage or resistant weed species are present, you can use Katagon as part of a two-pass sequential weed control program.

Field Trial Data

Delivering  broad-spectrum postemergence weed control activity, Katagon is a flexible fit for growers wanting the freedom to farm with less restrictions and limitations.

In product development trials, Katagon has shown high levels of performance in controlling emerged broadleaf and grass weeds, including biotypes resistant to glyphosate, PPO, triazine and ALS.
