Evaluation of Triasulfuron Alone and as Tank Mixture with Clodinafop, Fenoxaprop, Sulfosulfuron or Tralkoxydim against Complex Weed Flora in Wheat

摘要

Weed control efficacy of clodinafop at 50 g, fenoxapiop at 100 g, sulfosulfuron at 20 g and tralkoxydim at 300 g ha~(-1) ranged between 78-96% on grassy weeds. These herbicides were totally ineffective against broadleaf weeds except sulfosulfuron. Triasulfuron was not effective against grassy weeds, but very effective on all broadleaf weeds. The efficacy of clodinafop at all combinations with triasulfuron was reduced in controlling grassy weeds. However, efficacy of triasulfuron was not affected dueto tank mixing.
