摘要: 为防治小麦病害,提高产量,增加效益,本文采用杀菌剂和植物生长调节剂的组合进行小麦田间药效试验。结果表明:与不施药和施用常规药剂相比,处理2、3对小麦赤霉病、白粉病均有较好的防治效果。尤其是对小麦白粉病防治效果显著,处理2、处理3对白粉病的病情指数防治效果分别为99.79%、99.80%;处理2和处理3对赤霉病的病情指数防治效果均为85.71%。处理2和处理4对纹枯病的防治效果一般,为66.67%,处理3对纹枯病的病穗率防治效果较好,为100.00%。因此,在纹枯病发生较重田块,推荐使用处理3的药剂组合。与对照相比,各项处理均提高了小麦产量,增产范围7.36%~11.98%,667 m2增加效益124.88~203.29元,可能是由于处理2和处理3施用的植物生长调节剂的增产效果好。本次试验的2个组合药剂可防治多种小麦病害,有助于促进农药减量增效,并且有一定的增产效果,可进一步推广使用。

Abstract:

To prevent wheat diseases, improve yield, and enhance economic benefits, this study conducted field efficacy trials using a combination of fungicides and plant growth regulators. The results showed that treatments 2 and 3 exhibited superior control efficacy against Fusarium head blight and powdery mildew in wheat compared with untreated plots and conventional chemical treatments. Notably, their control efficacy against powdery mildew was particularly significant, with treatment 2 and 3 achieving 99.79% and 99.80%, respectively. Both treatments also demonstrated 85.71% efficacy against Fusarium head blight. Treatment 2 showed moderate efficacy (66.67%) against sharp eyespot, while treatment 3 achieved complete control (100.00%). Therefore, treatment 3 is recommended for fields with severe sharp eyespot outbreaks. All treatments increased wheat yield by 7.36%-11.98%, with economic benefits rising by 124.88-203.29 yuan per 667 m2 compared to the control, likely due to the yield-enhancing effects of the plant growth regulators in treatments 2 and 3. The two combination treatments effectively controlled multiple wheat diseases, promoted pesticide reduction and efficiency, and improved yield, demonstrating potential for broader application.
