乙福酮超微粉体种衣剂对小麦和玉米前期病虫害防治效果的研究

Effect of Acephate triadimefon Ultra fine Dust Seed coating Agent on Control of Disease and Pests of Wheat and Maize in Earlier Stage of Growing Period

通过药剂筛选、盆栽试验、田间小区和大田示范试验对乙福酮超微粉体种衣剂的杀菌剂配方筛选及其对小麦玉米前期病虫害防治效果进行研究调查得出 ,福 :酮 =4∶ 1复配剂是种衣剂中杀菌剂的理想配方 ;乙福酮超微粉体种衣剂能有效防治小麦根腐病、腥黑穗病及地下害虫 ,药种比 1∶ 50 0的剂量对小麦病虫害综合防效最佳 。

In this study, agents screening, pot and plot experiments and demonstration test were employed to screen the fungicide formulation and clearify the effect of acephate thiram triadimefon ultra fine dust seed coating agent on the control of disease and pests of wheat and maize in earlier stage of growing period. The results show that thiram: triadimefon=4∶1 is the best formulation of seed coating agent, which can effectively control root rot, karnal bunt and soil insects of wheat. Agent: seed=1∶500 is the best ratio for controlling wheat diseases and pests.
