To screen out efficient pesticides for controlling the rapeseed downy mildew disease that are suitable for the ecological environment of Xizang, this experiment used the main cultivated variety Zangyou No.5 as the material, and adopted a random block design. Seven treatments were set up. Through field plot experiments, the effects of different pesticides on the control of rapeseed downy mildew, their safety, and yield were studied. The optimal control pesticide and application scheme were clarified. The results showed that there were significant differences in the efficacy, safety, and yield-increasing effects of different pesticides. Comprehensive analysis indicated that treatments A and B could be the preferred pesticides for controlling rapeseed downy mildew in Xizang. It was recommended that they be applied starting from the initial flowering stage, with a 7-day interval for two consecutive applications, and alternating use to delay the emergence of drug resistance. This experiment could provide technical support for the green disease control in the local area.

为筛选适配西藏生态环境的油菜霜霉病高效防治药剂,以主栽品种藏油5号为材料,设置7个处理,研究不同药剂对油菜霜霉病的防治效果、安全性及产量的影响,明确最优防控药剂及应用方案。结果表明,不同药剂的防效、安全性及增产效应差异显著:40%烯酰吗啉悬浮剂1 500倍液(A)和72%霜脲·锰锌可湿性粉剂800倍液(B)综合表现最优,施药后14 d防效分别达86.46%、84.68%,施药后21 d仍保持84.61%、82.61%的高水平防效;两种药剂对油菜安全无药害,较对照分别增产58.50%、50.27%,产量达3 306.51 kg/hm2、3 134.84 kg/hm2。综合分析可知,A、B处理可作为西藏地区油菜霜霉病的首选药剂,建议初花期始施、间隔7 d连施2次,交替使用以延缓抗药性。本试验可为当地病害绿色防控提供技术支撑。

为筛选适配西藏生态环境的油菜霜霉病高效防治药剂,以主栽品种藏油5号为材料,设置7个处理,研究不同药剂对油菜霜霉病的防治效果、安全性及产量的影响,明确最优防控药剂及应用方案。结果表明,不同药剂的防效、安全性及增产效应差异显著:40%烯酰吗啉悬浮剂1 500倍液(A)和72%霜脲·锰锌可湿性粉剂800倍液(B)综合表现最优,施药后14 d防效分别达86.46%、84.68%,施药后21 d仍保持84.61%、82.61%的高水平防效;两种药剂对油菜安全无药害,较对照分别增产58.50%、50.27%,产量达3 306.51 kg/hm2、3 134.84 kg/hm2。综合分析可知,A、B处理可作为西藏地区油菜霜霉病的首选药剂,建议初花期始施、间隔7 d连施2次,交替使用以延缓抗药性。本试验可为当地病害绿色防控提供技术支撑。

To screen out efficient pesticides for controlling the rapeseed downy mildew disease that are suitable for the ecological environment of Xizang, this experiment used the main cultivated variety Zangyou No.5 as the material, and adopted a random block design. Seven treatments were set up. Through field plot experiments, the effects of different pesticides on the control of rapeseed downy mildew, their safety, and yield were studied. The optimal control pesticide and application scheme were clarified. The results showed that there were significant differences in the efficacy, safety, and yield-increasing effects of different pesticides. Comprehensive analysis indicated that treatments A and B could be the preferred pesticides for controlling rapeseed downy mildew in Xizang. It was recommended that they be applied starting from the initial flowering stage, with a 7-day interval for two consecutive applications, and alternating use to delay the emergence of drug resistance. This experiment could provide technical support for the green disease control in the local area.
