摘要
试验结果表明，０．３％锐劲特颗粒剂防治稻水象甲成虫、幼虫速效性好，并且有持效，对一代二化螟也有兼治效果。田间药量１５００～２０００ｇ／６６７ｍ２，防治稻水象甲成虫效果达８１．７％～１００％，同对照药剂２０％三唑磷１００ｍｌ／６６７ｍ２和３％呋喃丹颗粒剂１５００ｇ／６６７ｍ２药效相当，防治幼虫效果达７７３％～１００％，对螟虫兼治效果均在６０％～８０％之间。
The results of trial showed that 0.3% fipronil GR was very effective againest rice water weevil( Lissorhoptrus oryzophilus Kuschel)and asiatic rice borer( Chilo supressalis Walker).Fipronil possessed fast effect and long persistent to control the pests.At the rate of 1500～2000g/667m 2,the control effect of rice water weevil adults was 81.7%～100%.At the rate of 1000～2000g/667m 2,the control effect of rice water weevil larvae was 77.3%～100%;and was 60%～80% on asiatic rice borer( Chilosupressalis Walker).
