摘　　要：纹枯病是水稻常见病害之一,为探究多种新型杀菌剂对宁波地区主栽水稻品种的控害效果及经济性状的影响,在宁波鄞州地区开展相关试验。结果表明,肟菌戊唑醇、啶氧丙环唑、苯甲嘧菌酯在晚稻上控害效果较好,且在穗粒数、结实率、产量等经济性状上较其他处理有显著正向影响,建议宁波地区主栽品种在晚稻生产上可以选用。新型药剂在早稻上表现一般,与其他药剂无显著差异。早稻纹枯病控害可以根据实际需求,选用噻呋酰胺等药剂组合。Sheath blight is one of the common diseases of rice,and in order to explore the effects of various new fungicides on the damage control effect and economic traits of the main rice varieties in Ningbo,relevant experiments were carried out in Yinzhou,Ningbo.The results showed that tebuconazole,pyroxypropiconazole and benzoxystrobin had better damage control effects on late rice,and had a significant positive impact on economic traits such as grain number per panicle,seed setting rate and yield compared with other treatments.The performance of the new fungicides in early rice was general,and there was no significant difference among the new fungicides and other agents.Early rice sheath blight control can be based on actual needs,and the combination of thiofuramide and other fungicides can be selected.
