INTEGRATED MANAGEMENT OF PHALARIS MINOR AND AVENA FATUA IN WHEAT TO TACKLE HERBICIDE RESISTANCE

Abstract
Recent intensification in herbicide resistant weeds is major challenge for sustainable wheat production in all major wheat producing countries. Potential of integrated resistant management strategies to manage weeds in wheat is essential to be evaluated for sustainable wheat production. Two year field study was conducted during 2014-15 and 2015-16 to determine the efficacy of sunflower, rice, maize and sorghum mulches alone and in combination with three types of herbicide mixtures (clodinafop-propargyl plus metribuzin, sulfosulfuron plus clodinafop-propargyl and pinoxaden plus sulfosulfuron) to manage Phalaris minor and Avena fatua in wheat. Solo application of either allelopathic mulches 8 t ha-1 or herbicide mixtures did not provide acceptable weed control (24-52% and 54-80% respectively); whereas integration of allelopathic mulches with herbicide mixtures provided effective weed control (74-94%). All treatments positively influenced the wheat growth and caused 21% to 39% increase in wheat grain yield. Integration of herbicide mixtures with allelopathic crop mulches can be used effectively for sustainable control of P. minor and A. fatua in wheat to avoid herbicide resistance.
