Abstract
The dry weight of maize shoot, the test plant increased significantly with each successive increase in temperature level from 15-35°C and incubation period from 0-120 days. Whereas increase in concentration of chlorsulfuron (0 to 40 ppb) caused significant reduction in dry weight of maize shoot. At 120 days of incubation, the GR,o (Growth reduction 50%) at 35°C was approximately 10 times higher than that at 15°C. The half-life of chlorsulfuron was 142, 93 and 80 days at 15, 25 and 35°C, respectively.
