【摘要】 为筛选出有效防治花生叶斑病的新型药剂,以传统药剂多菌灵为对照,采用三次叶面喷雾法测定了12种新型杀菌剂对叶斑病的防治效果及产量影响,结果表明:12种新型杀菌剂对花生叶斑病的防治效果在18.27%~44.24%之间,其中有效成分为25%吡唑醚菌酯、60%唑醚·代森联、32.5%嘧菌酯·苯醚甲、12%氟环唑、490g/L丙环·咪鲜胺、30%苯甲·丙环唑、46.1%氢氧化铜的防治效果较好,达到30%以上。从产量结果来看,各处理对花生产量增幅在10.53%~25.00%之间,其中增产效果最好的是75%肟菌·戊唑醇、25%吡唑醚菌酯、60%唑醚·代森联,增产效果分别为25%、20.8%和20.3%,显著优于其他药剂。总体来看,12种杀菌剂对花生叶斑病的防治效果与增产效果呈一致趋势。更多还原

【Abstract】 In order to choose effective fungicides for peanut leaf spot,we applied carbendazim as control and 12other fungicides to determine their control effect on peanut leaf spot through 3times of foliar spray.The results showed that the control effect of 12fungicides to peanut leaf spot was 10.53%~ 44.24%.Among them,pyraclostrobin 25%,pyraclostrob·polyram 60%,azoxystrobin-phenylate 32.5%and epoxiconazole 12%exhibited better effect.The yield result showed that yield increase of all treatment was 10.5%~25.0%.The increase effect of oxime·tebuconazole 75%,pyraclostrobin 25%,pyraclostrob·polyram 60%,epoxiconazole 12%,benzyl·propicona-zole 30% and copper hydroxide 46.1% were better than other fungicides.Overall,fungicides with good control effect to peanut leaf spot improved peanut yield.更多还原
