Performance of Pinoxaden Herbicide against Complex Weed Flora in Wheat (Triticum aestivum L.)

A field experiment was conducted during rabi season (2020-21) at AICRP on Wheat, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP), India, to study the effect of pinoxaden on weeds and the yield of wheat. The field experiment was laid out in a randomized block design with seven treatments and replicated thrice. Treatments included applying different doses of pinoxaden at 40, 45, and 90 g a.i. ha-1, clodinafop propargyl at 90 g a.i. ha-1, sulfosulfuron at 25 g a.i. ha-1 as post-emergence along with hand weeding at 30 DAS and weedy check. The experimental field was dominated by Phalaris minor (15.6%) among monocot weeds, while Medicago denticulata (30.82%), Cichorium intybus (29.94%), Chenopodium album (15.32%), and Anagallis arvensis (8.30%) among the dicot weeds throughout the crop growing period. Among the different herbicidal treatments, pinoxaden at 90 g a.i. ha-1 effectively controlled the monocot and dicot weeds and recorded higher weed control efficiency and the lowest weed index. However, the highest value of growth parameters, yield attributes, and grain yield was recorded with the application of pinoxaden at 45 g a.i. ha-1 among all the herbicidal treatments.
