摘要
１９９１～１９９２年研究了好年冬主要成分卡巴噻吩的残留降解规律．在自然条件下，卡巴噻吩会迅速转化为卡巴呋喃和３－羟基卡巴呋喃．因３－羟基卡巴呋喃降解慢而成为主要残留物．２０％好年冬乳剂稀释１５００～７５０倍喷湿柑桔树叶，３０ｄ后收获的柑桔（果皮和果肉），食用是安全的．
The residue and degradation of Carbosulfan,the
active ingredient of the insec-ticide Marshal,in orange (peel,pul pand whole fruit)and in soil
were studied during 1991～1992.Under field conditions,Carboulfan could been rapidly
transformed into Carbosfuranand 3-Hydroxyl Carbofuran.3-Hydroxyl Carbofuran was major
residue,for it degradedslowly. Marshal 20% EC was diluted to 750～1500 times with water,and
it was sprayed up-on orange plants,thirty days later,the harvested oranges(peel and pulp)were
safe for food.
