摘要: 摘 要:为有效控制玉米地下害虫、蚜虫和茎基腐病的常年危害,筛选具有较好控制作用的种衣剂,笔者开展了14种悬浮种衣剂田间药效试验。试验表明:14种种衣剂对供试玉米品种出苗安全;氟虫腈?噻虫嗪(30%悬浮种衣剂)(1:1000)处理的出苗率96.7%为最高值。氟虫腈?噻虫嗪(30%悬浮种衣剂)(1:1000)对玉米地下害虫、玉米蚜虫的防治效果分别达84.8%、80.0%。精甲?咯?嘧菌(11%悬浮种衣剂)(1:2000)对玉米茎基腐病的防治效果达73.7%。说明以噻虫嗪、氟虫腈和甲霜灵为主的复配防治玉米地下害虫、蚜虫、茎基腐病,能够取得较好的防治效果。建议针对不同的生态类型区域,结合品种、施肥、管理等措施选用不同的配方,以取得最佳的防治效果。

Abstract: To effectively control the perennial damage of corn underground pests, aphids and stalk rot, and to screen seed coating agents with better control effect, 14 kinds of suspension seed coating agents were tested in field. The results showed that the 14 kinds of seed coating agents were safe for corn seedling emergence, and the highest seedling emergence rate was 96.7% when corn seeds were treated with fipronil-thiamethoxam (30% suspended seed coating agent) (1:1000). The control effect of fipronil and thiamethoxam (30% suspension seed coating agent) (1:1000) on corn underground pests and corn aphids was 84.8% and 80.0%, respectively. The control effect of metalaxyl-M, fludioxonil and amistar (11% suspension seed coating agent) (1:2000) on stalk rot was 73.7%, indicating that the combination of thiamethoxam, fipronil and metalaxyl could control corn underground pests, aphids and stalk rot effectively. It is suggested that different formulations should be selected according to different ecological types and regions, combining with varieties, fertilization and management measures, so as to achieve the best control effect.
