Tank mix application of cyhalofop-butyl with selected herbicides for weed control in wet-seeded rice

The experiment was conducted during September 2015 to January 2016 in a farmer's field one meter below of mean sea level in Thrissur district of Kerala. Tank mix application of cyhalofop-butyl (80 g/ha) with pyrazosulfuron-ethyl (30 g/ha) at 18 DAS gave effective control of mixed weed flora in wet-seeded rice. It is not advisable to tank mix cyhalofop-butyl with Almix® as it will lead to complete loss of activity of cyhalofop-butyl. Tank mixing of pre emergence herbicides with cyhalofopbutyl was found to be less effective than their sequential application.
