摘要: 为了研制防治小麦纹枯病的安全高效种衣剂,采用生长速率法测定了噻呋酰胺和氟硅唑对小麦纹枯病的联合毒力,确定了最优配比,利用砂磨法将药剂加工成种衣剂,并测定了种衣剂对小麦纹枯病的田间防效。结果表明:噻呋酰胺与氟硅唑在1:2比例时显示了一定的增效作用,其余比例显示了一定的相加作用;正交试验2筛选的配方没有析出,没有挂壁,流动性好底部无沉淀,为可选配方;热贮2周后,稳定性好;自制种衣剂对小麦纹枯病显示了很好的防效,不同包衣比例防效均在90%以上,显著高于对照药剂咯菌腈、戊唑醇和苯醚甲环唑。配制的种衣剂对小麦纹枯病有很好的防效,可作为小麦包衣的替代药剂。

Abstract: In order to study the effectiveness of wheat seed coating agent in wheat sharp eyespot prevention, the co-toxicity of thifluzamide and flusilazole to wheat sharp eyespot were tested using growth rate method, and the optimal ratio was determined. The control effect of wheat seed coating on wheat sharp eyespot was also tested. The results showed that the optimal ratio of thifluzamide and flusilazole was 1:2, and the orthogonal test six had the best results, the stability of wheat seed coating was still well after two weeks’ geothermal reservoir. The control effect was more than 90%, significantly higher than that of the comparison. In conclusion, the seed coating agent is efficient to the prevention of wheat sharp eyespot, it is a substitute pesticide.
