Preliminary Study on the Effect of Protectant CGA123407 in Protecting Rice Seedlings from Injury by Acetochlor

Rice was very sensitive to acetochlor. Rice seedlings were injured when acetochlor was used in rice field. But acetochlor showed less phytotoxicity to rice seedling when used in combination with protectant CGA 123407 . The activities of endogenous protective enzymes, superoxide dismutose (SOD), peroxidase (POD) and catalase (CAT) were studied, and the results showed that the effect on the activities of endogenous protective enzymes was not the main injury mechanism of acetochlor.
