There was no control of Echinochloa colona due to application of bentazon, blazer or their ready mix formulation. Bentazon applied alone or in combination with blazer caused drastic reduction in the density of Celosia argentea, Trianthema monogyna and Cleome viscosa. Bentazon as follow up application over pre-plant incorporation of fluchloralin provided effective control of both grasses and non-grasses. The lowest weed dry matter production was recorded in plots treated with fluchloralin followed by bentazon or bentazon+blazer. Grain yields were significantly higher due to the bentazon at 720, 1200 and 2400 g ha−1 than at 540 g ha−1.
