【摘要】 在小麦齐穗期至盛花期用48%氰烯菌酯·戊唑醇悬浮剂、0.01%芸苔素内酯可溶液剂和10%吡虫啉可湿性粉剂桶混施药,测定其对小麦病虫害的综合防控及增产效果。结果表明,使用不同药剂处理,氰烯菌酯组合物桶混施药对小麦赤霉病、白粉病和锈病防治效果显著,均高于其他处理,分别为91.92%、84.31%、77.95%;药后1、3、7 d对蚜虫的防效也均高于其他处理,分别为52.50%、89.56%和95.30%。通过理论测产,此组合物产能最高,为7521.75 kg/hm~2,显著高于其他处理,增产作用明显,增产率为38.53%。更多还原

【Abstract】 Diseases and pests generally occur together since wheat enters flowering stage, affecting the yield and quality of wheat. In this article, 48% cyanoestrobin · tebuconazole SC, 0.01% brassinolide SL and 10% imidacloprid WP were mixed and employed from full heading stage to full flowering stage to determine the integrated control effect of the mixture on wheat diseases and pests, as well as the yield increase. The results showed that the control efficacy of cyanoestrobin on wheat scab, powdery mildew and rust was significantly higher than other treatments(91.92%, 84.31% and 77.95%,respectively). The control efficacy of 1 d, 3 d and 7 d on aphids was 52.50%, 89.56% and 95.30%, respectively, which were also higher than other treatments. The average yield per hectare of the composition was 7251.75 kg/hm~2 according to theoretical yield measurement, which was significantly higher than other treatments. The yield increase rate was 38.53%.更多还原
