In order to estimate the security of fomesafen to maize, we discussed the sensibility difference and the mechanism between different varieties of maize to fomesafen through the toxic soil method and the determination of enzyme activity. There were large differences of the sensibility to fomesafen among different maize varieties. And the most sensitive one was Dongnong888, IC50 was 0.59 mg · kg-1, and Kennian1 was the next, the resistance index was only 1.10. The sensibility of other eight varieties such as ...
