摘要: 采用双因素试验设计,分别采用4种不同药剂、3种不同施药次数开展对玉米灰斑病和大斑病药效防控试验。结果表明,防控玉米灰斑病和大斑病施用药剂以A2即苯甲·丙环唑(水乳剂)为最优,一次施药即可,通过防控病害能达到较好的增产效果。药剂A1即杜帮·克露(杀菌剂)和药剂A3即三唑酮(可湿性粉剂)施药3次也能较好地防控灰斑病,但对大斑病防治效果不佳,有一定增产效果。实际生产中推荐使用药剂A2即苯甲·丙环唑(水乳剂)、用量750 mL/hm2(有效成分苯醚甲环唑含量15%、丙环唑含量15%),在玉米植株抽雄后及时施药1次。

Abstract: The effects of four different pesticides and three different modes of application on the control of grey leaf spot and large leaf spot in maize were conducted with two-factor design to determine. The results indicated that the best potion against grey leaf spot and large leaf spot in maize is Benzoyl propiazole (water emulsion) (A2),and it could prevent disease and increase production effectively with one application. Applied DuPont klou (fungicide) (A1) and triadimefon (wettable powder) (A3) three times can prevent grey leaf spot disease and increase yield in some degree but without good effect for large leaf spot. We suggested producers spray A2(difenoconazole 15%,propiconazole 15%) 750 mL/hm2 one time after plant sampling in the process of practical production.

Key words: maize, grey leaf spot, large leaf spot, effect of prevention and control
