通过大田试验,调查了18.5%适·甲柳悬浮种衣剂包衣对小麦出苗的影响及苗期病害(茎枯病、根腐病、散黑穗病、腥黑穗病)及地下害虫(蛴螬、蝼蛄、金针虫、地老虎等)的防治效果。结果显示:18.5%适·甲柳悬浮种衣剂包衣对小麦出苗有促进作用,表现为出苗率提高,出苗整齐,对作物安全,优于生产上常规种衣剂。18.5%适·甲柳悬浮种衣剂1∶20∶400(药∶水∶种)包衣处理对小麦苗期根部病害和地下害虫防效最好,对病害防治效果为94.4%,对地下害虫防治效果高达100%;其次是18.5%适·甲柳悬浮种衣剂1∶20∶500(药∶水∶种)包衣处理,对小麦苗期根部病害和地下害虫的防效分别达到89.8%和97.4%。18.5%适·甲柳悬浮种衣剂是一种优良的小麦种子处理剂,值得大力推广应用,综合防治效果和成本考虑,使用剂量以1∶20∶500(药∶水∶种子)包衣为宜。
Through field experiments, the effects of 18.5% suspension of seed dressing with a willow suspension on wheat emergence and seedling diseases (stem blight, root rot, casual smut and blind smut) and underground pests蛴 螬, 蝼 蛄, pinworm, to the tiger, etc.) control effect. The results showed that the 18.5% suspension of seed dressing with aphids could promote the emergence of wheat, which showed that the emergence rate was improved, the emergence was neat, and the crop safety was better than the conventional seed coating in production. 18.5% of the seedlings of aphids will be 1:20:400 (medicine: water: seed). The coating treatment has the best control effect on the root diseases and underground pests of wheat seedling. The control effect on the diseases is 94.4% The control effect was as high as 100%, followed by the coating of 18.5% aphid-suspending seed coating 1:20:500 (medicine: water: seed), the control effect on root disease and underground pest of wheat seedling reached 89.8% And 97.4%. 18.5% Aloe vera L. seed coating agent is an excellent seed treatment agent for wheat. It is worth popularizing. Considering the control effect and cost, 18.5% should.
