噻呋酰胺等杀菌剂防治小麦纹枯病田间试验

Field Trials of Seven Fungicides Including Thifluzamide Against Wheat Sharp Eyespot

为筛选防治小麦纹枯病的高效、低毒、安全型杀菌剂,2012年选择了噻呋酰胺等7个杀菌剂产品进行了田间药效试验。结果表明,24%噻呋酰胺SC防治小麦纹枯病效果最好,5%井冈霉素AS、20%烯肟.戊唑醇SC及33%多.酮WP的防效一般,12.5%烯唑醇WP、30%苯甲.丙环唑EC及25%丙环唑EC的防效较差,各药剂均对小麦生长安全。经分析比较,优先推荐24%噻呋酰胺SC和5%井冈霉素AS用于防治小麦纹枯病。

In order to screen excellent,low-toxic and safe fungicides for controlling wheat sharp eyespot,the control efficiencies of seven fungicides were compared by wheat field trials.The results showed that the field efficiency of thifluzamide 24% SC was high,the field efficiencies of validamycin 5% AS,SYP-1620 ＋ tebuconazole 20% SC and carbendazim ＋ triadimefon 33% WP were medium,and the field efficiencies of diniconazole 12.5% WP,difenoconazole ＋ propiconazole 30% EC and propiconazole 25% EC were low.All fungicides tested were safe to wheat.According to the results,thifluzamide 24% SC and validamycin 5% AS could be used to control wheat sharp eyespot.
