The field experiments were conducted at Department of Oilseeds, Tamil Nadu Agricultural University, Coimbatore during kharif seasons for three consecutive years from 2013 to 2015. The experiment was laid out in randomized block design with eight treatments. The crop was irrigated as per the requirement and recommended dose of fertilizers were applied for better growth and development. Pre emergence application of pendimethalin @ 1.0 kg ai/ha followed by one hand weeding at 30 DAS is the best IWM practice for getting effective and economical weed control in irrigated sunflower. Combinations of pre emergence herbicide pendimethalin and post emergence herbicides viz., quizalofop ethyl, propaquizofop and fenoxyprop ethyl was not effective against broad leaved weeds infested field in sunflower, though they were not were phytotoxic to sunflower.
