摘　　要：对30%辛硫磷微胶囊悬浮剂进行了残毒桑叶饲养家蚕试验和防治桑园害虫田间试验。结果表明:该药剂对家蚕毒性中等,药后对家蚕的安全间隔期为13～15 d。该药剂500～1000倍稀释液对桑园害虫的防治效果显著优于对照药剂60%辛硫磷乳油1500倍稀释液的防治效果。30%辛硫磷微胶囊悬浮剂初期使用的浓度以1000倍左右为宜。The rearing test of silkworm fed on the mulberry leaves with the residual toxin of 30% phoxim microcapsule suspension was conducted,and the control effect of this insecticide against the insect pests in mulberry garden was studied in the field.The results showed that 30% phoxim microcapsule suspension had medium toxicity to silkworm,and the safe interval from its application to the rearing of silkworm was 13~15 days.The 500~1000 times diluent of 30% phoxim microcapsule suspension had significant better control effects on mulberry insect pests than the 1500-fold dilution of 60% phoxim emulsifiable concentrate.The proper usage concentration of 30% phoxim microcapsule suspension was about 1000-fold at the initial stage.
