Abstract:Taking Zhengdan 958 maize as trial crop,this paper studied the detoxification effects of three kinds of antidotes(cloquintocet-mexyl,fenchlorazole,mefenpyr-diethyl) on the nicosulfuron’ s phytotoxi-city to maize by different treatments. It was shown that the corn’ s leaf number,stem diameter,plant height and aboveground fresh weight respectively decreased by 23 . 25%,33 . 62%,25 . 61% and 45 . 73%, and the output decreased by 20. 37% after spraying nicosulfuron(90 g/ha active ingredients) at the stage of five leaves. Mixing cloquintocet-mexyl(3 g/kg) with seeds had relatively better comprehensive detoxifica-tion effects in the corn’ s leaf number,stem diameter,plant height and aboveground fresh weight,the relief rates were separately 28 . 55%,46 . 30%,33 . 98%,75 . 18%, and the output relief rate was 13 . 80%. In conclusion,mixing cloquintocet-mexyl with seeds could be used to relieve nicosulfuron ’ s inhibition on growth and development of maize.
