Abstract：Taking Zhengdan 958 maize hybrid as trial crop ,the phytotoxicity of nicosulfuron on maize and the mitigation effects of different antidotes were studied .It turned out that nicosulfuron (120 g/ha) had a serious impact on corn ,the plant height declined by 8 .69% ,and the output de-creased by 11 .18% .The quantitative AA ,NAA ,PGAE and BR could improve the inhibition of ni-cosulfuron on the corn growth ;The NAA and DA-6 could alleviate the effect of nicosulfuron on the chlorophyll content of corn ;Spraying all the antidotes at early or later stage of phytotoxicity could reduce the effect of nicosulfuron on the MDA content of corn ;The NPK could also alleviate the effect of nicosulfuron on the soluble sugar content of corn at the later stage of phytotoxicity .Com-pared with the control (120 g/ha nicosulfuron ,without antidotes ) ,the yield of PGAE treatment at the later stage of phytotoxicity increased by 24 .47% .By comprehensive analysis ,the alleviative effect of 1 .2 g/ha PGAE to the nicosulfuron’s phytotoxicity on maize was relatively better .
