Abstract

This greenhouse study determined the effect of temperature on the herbicide acetochlor. The herbicide was applied a day after planting at the rates of 0.74, 1.47, 2.94 and 5.85 kg ha-1. Plants were kept at three temperature: supra-optimal (35/28 0 C), optimal (28/18 0C) and sub-optimal (15/08 0C). Significant interactions were observed for herbicide rate x temperature x cultivars. Generally seedlings at the optimal and supra-optimal temperatures grew faster and passed the seedling stage rapidly.
