近几年稻曲病在我省发生日趋严重,已成为水稻生产上急待解决的问题。1986年,我们进行了粉锈宁防治稻曲病试验,也取得了较好的防治效果。试验水稻品种是辽粳5号,试验地点在铁岭县新台子乡。每亩用25％粉锈宁100克,于8月6日(水稻出穗前约7 天)施药,穴防效为94％,穗防效为79.8％,粒防效为81.5％,对 In recent years, Soybean disease is increasingly serious in our province and has become an urgent problem to be solved in rice production. In 1986, we conducted trials of triadimefon against rice false smut and also achieved good control effects. The experimental rice variety is Liaojing 5, and the test site is in Xintaizi, Tieling County. 100 grams per acre with 25% triadimefon, on August 6 (about 7 days before rice heading out), the hole control efficiency was 94%, panicle control effect was 79.8%, grain control effect was 81.5%
