Echinochloa colona was more tolerance while Digitaria adscendense was medium tolerance but Dactyloctenium aegyptium was susceptible to cyclohexenes when applied at 1, 2 and 3 weeks after soybean germination. At 2 and 3 weeks after soybean germination grasses were more susceptible to herbicides than application at 1 week after germination. However cycloxydim provided more efficacy on weed control than others while clethodim gave slightly better control than sethoxydim. Application of herbicides at different stages of growth did not affect yield of soybean. However, there were different between herbicides, cycloxydim increase yield more than clethodim and sethoxydim. But yield of soybean treated with clethodim did not different from sethoxydim. Yield of soybean increased with the rate of herbicides was increased.
