The dry weight of sorghum shoot (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 sulfosulfuron (0 to 64 ppb) caused significant reduction in dry weight of sorghum shoot. At 120 days of incubation, the GR50 (Growth reduction 50%) at 35°C was approximately 2.5 times higher than at 15°C. The half life of sulfosulfuron was 46, 28 and 11 days at 15, 25 and 35°C, respectively.
