【摘要】 对 48 %乐斯本乳油在水稻、苹果和韭菜上消解动态和最终残留量进行测定的结果表明 ,在水稻、苹果、韭菜及田间土壤中的半衰期约为 1～ 3天 ,1 0～ 2 0天可降解 95 % ;在稻田水中的半衰期约为 1天 ,3～ 7天可降解 95 % ;最终残留量均符合FAO/WHO规定的最高残留限量 (MRL值 )标准 ,依此建立该药在这 3种作物上的合理使用方法更多还原

【Abstract】 Testing the dispel trends and final residues of 48% lorsban on rice,apple and Chinese chive,results show that the half life of 48% lorsban on rice,apple,Chinese chive and soil is 1~3 days,after 10~20 days 95 percent 48% lorsban can be decomposed;the half life is 1 day in the water of rice field,95 percent can be decomposed after 3~7 days;the final residues on rice,apple,Chinese chive are all fit with the standards of maximum residue limit(MRL),according to the results,we set up suitable methods of 48% lorsban on these crops.更多还原
