摘要
为了评价醚菌酯在苹果上使用后的残留动态及环境安全性,在天津、西安两地同时进行了醚菌酯在苹果上的残留动态实验。结果表明:在天津地区,醚菌酯在苹果上的半衰期为10.2d,在土壤中的半衰期为12.6d;在西安地区,醚菌酯在苹果上的半衰期为7.3d,在土壤中的半衰期为11.6d。施药后间隔14d和21d的苹果中醚菌酯的残留量均低于0.2mg/kg。
Field trail for kresoxim-methyl residue in apple and soil were conducted in Tianjin and Xi＇an province, respectively. The results showed that the half-life of degradation for kresoxim-methyl was 10.2 d in apple, 12.6 d in soil in Tianjin. The half-life of degradation in Xi＇an was 7.3 d in apple, 11.6 d in soil. The terminal residue in apple samples was less than 0.2 mg/kg.
