Abstract:

A field trial was conducted to evaluate different doses of herbicides for weed control in transplanted rice during Kharif season 2014 at Pantnagar. Experiment was laid out in a randomized block design with three replications. Results showed that all the herbicides were effective in reducing the total density of weeds at all the growth stages and enhancing the rice yield. Application of pretilachlor (SS) 1000 and 1500 g/ha applied as pre-emergence proved to be most effective followed by its lower doses applied at 750 g/ha in decreasing the density of weeds (30 and 60 DAT) than the other treatments. None of the herbicides found phytotoxic to rice crop.
