|Section2= |Section3= }} Metalaxyl is a phenylamide fungicide with systemic function. Its chemical name is methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate. It can be used to control ''Pythium'' in a number of vegetable crops, and ''Phytophthora'' in peas. Metalaxyl-M is the trade name of the optically pure stereoisomer. It is the active ingredient in the seed treatment agent Apron XL LS.〔http://www.gov.mb.ca/agriculture/crops/vegetablecrops/pdf/bmz10s02.pdf〕 The fungicide has suffered severe resistance problems. The fungicide was marketed for use against ''Phytophthora infestans''. However in the summer of 1980, in the Republic of Ireland, the crop was devastated by a potato blight epidemic after a resistant race of the oomycete appeared.〔(Working on potato blight in Northern Ireland )〕 Irish farmers later successfully sued the company for their losses. Maximum pesticide residue limits for the EU/UK are set at 0.5 mg/kg for oranges and 1.0 mg/kg for apples ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Metalaxyl」の詳細全文を読む スポンサード リンク
