In growth room bioassays, safener AD-67(N-dichloroacetyl-1-oxa-4-azaspiro-4,5-decane) was determined for its effectiveness in reducing chlorsulfuron [1-(2-chlorophenylsulfonyl)-3-(4-methoxy-6-methyl-1,3,5-triazin-2-yl) urea] injury to maize seedling. The effect of AD-67(N-dichloroacetyl-1-oxa-4-azaspiro-4,5-decane) on glutathione (GSH), Glutathione S-transferase (GST), and Acetolactate synthase (ALS) in corn (Dongnong248) were examined. In the absence of AD-67 treatment, the non-enzymatic conjugation of the herbicide with glutathione exceed. We demonstrate that AD-67 act to enhance the major group of phase detoxification enzymes (GST) and ALS. These results are consistent with the hypothesis that AD-67 protect corn by enhancing GST, ALS activity which results in accelerated detoxification of chlorsulfuron via GSH conjugation. By choosing the right combination of AD-67 and plant it should be possible to enhance the tolerance of corn injury by chlorsulfuron.
