不同杀菌剂防治稻曲病田间药效评价(毕业论文9350字)
摘 要：为筛选出经济、安全、高效的防治稻曲病的新型杀菌剂，我们对不同生产厂家的70%甲基硫菌灵WP、20%三环唑WP、15%三唑酮WP、70%代森锰锌WP、50%多菌灵WP、20%井冈霉素AP、40%稻瘟灵EC、12．5%烯唑醇WP、43%戊唑醇SC、30%丙环唑+苯醚甲环唑 EC等10个杀菌剂进行了大田对比试验和不同药剂（组合）实验，结果表明,以丙环唑+苯醚甲环唑防效最好,烯唑醇、戊唑醇、井冈霉素与丙环唑+苯醚甲环唑相比防效没有显著性差异,四者显著优于多菌灵的防效。

Different fungicide prevention rice false smut field efficacy evaluation
Abstract: For economic, safe, efficient were the prevention and control of the new fungicide rice false smut of different manufacturer,we us to the different manufacturers of 70% Thiophanate methyl,20% of Tricyclazole WP,15% of Triadimefon WP,70% of Mancozeb WP，50% of Carbendazim WP , 20% of Jinggangmycin AP, 40% of Isoprothiolane EC, 12.5% of Diniconazole WP, 43% of Tebuconazole SC,30% of Difenoconazo le· Propiconazole EC and other 10 microbicides conducted field contrast test and different elixir (combinations) experiments, The results indicated that the Difenoconazo le· Propiconazole EC control effect is best, Diniconazole, Tebuconazole ,Jinggangmycin interact with Difenoconazole· Propiconazole compared triazoles benzene ether control effect, no significant difference was significantly better than 4 person control effect of the Carbendazim.
