研究了0．5％多杀菌素对蓟马的室内毒力测定和田间药效试验。结果表明，其室内测定LC50为5．37μg·mL^-1，田间7d防治效果为91．11％。说明其有较好的防治效果，持效期在7d以上，对蓟马的推荐使用剂量为26．25—37．5g·ha^-1。
研究瞭0．5％多殺菌素對薊馬的室內毒力測定和田間藥效試驗。結果錶明，其室內測定LC50為5．37μg·mL^-1，田間7d防治效果為91．11％。說明其有較好的防治效果，持效期在7d以上，對薊馬的推薦使用劑量為26．25—37．5g·ha^-1。
연구료0．5％다살균소대계마적실내독력측정화전간약효시험。결과표명，기실내측정LC50위5．37μg·mL^-1，전간7d방치효과위91．11％。설명기유교호적방치효과，지효기재7d이상，대계마적추천사용제량위26．25—37．5g·ha^-1。
Indoor toxicity and field efficacy were tested to determine theefficacies of 0. 5% spinosad emulsion in water in controlling the pest of Thrips palmi Karny. The results indicated that LC50 was 5.37 μg· mL-1 indoor toxicity and the corrected field efficacy for 7 d was 91.11%. It was stated that the validity period of field efficacy was better, and the recommend dose was 26.25 g/ha - 37.5 g/ha.
