Abstract
Metalaxyl was acidified to its acid and the synthetized antigens were prepared by coupling the acid to carrying protein with the method of mixed anhydride and were used as immunogenes to immunize the rabbits.The titer of the antisera measured with indirect ELISA was1∶ 204 800. The determination method for metalaxyl was set up.The range of detection was 1 953 ng/mL to 250 0 ng/mL,which was fit for the demand of quantitative determination of Metalaxyl in plant products.The coincidance rate between the test and the gas chromatography was 92%.The average recovery of fortified rice,wheat and tomato was 97%,97 47%and 99 45%respectively.Cross reactivity indicated that the antisera could only react with metalaxyl and its acid,but not with those matters whose structures are similar to metalaxyl including metolachlor,diethatyl ethyl,alachlor propachlor and benzoylprop ethyl.This method is simple,rapid and sensitive and fit for determination of metalaxyl residue in plant products.
