[目的]研究28%烯肟菌酯·多菌灵(佳思翠)对小麦赤霉病的防治效果。[方法]以德麦15为供试品种,在小麦扬花初期分别试验不同药剂[佳思翠、多菌灵、劲护(25%氰烯菌酯悬浮剂)]及佳思翠不同剂量(900、1 200、1 500 g/hm2)对小麦赤霉病的防效,以及对小麦经济形状的影响。[结果]佳思翠1 500 g/hm2处理对小麦赤霉病的防治效果最好,药后14 d的防效达87.96%;其次为25%氰烯菌酯悬浮剂1 500 g/hm2,药后14 d的防效达79.97%。且佳思翠1 500 g/hm2处理小麦千粒重最重,为45.35 g,1 hm2产量达4 645.20 kg,与其他处理间差异显著。[结论]佳思翠对小麦赤霉病具有明显防治效果,可减少小麦千粒重损失,是防治小麦赤霉病的有效杀菌剂,推荐在生产上大面积推广施用,施用剂量以1 500 g/hm2为宜。
[Objective] The research aimed to study the control effect of 28% enoximoside and carbendazim on wheat scab. [Method] With Demai 15 as the tested variety, the effects of different drugs [Jiasi Cui, Carbendazim, Jin Huai (25% GFP)] and different doses (900 , 1 200,1 500 g / hm2) on wheat scab and the impact on the economic shape of wheat. [Result] The best treatment effect of Jiasui 1 500 g / hm2 on wheat scab was the best. The control effect was 87.96% on the 14th day after the treatment. The second was 25% of the suspension of 1 500 g / hm2, After 14 days of drug control effect of 79.97%. The highest grain weight of 1 500 g / hm2 treated by Jiasipeng was 45.35 g and the yield of 1 hm2 was 4 645.20 kg, which was significantly different from other treatments. [Conclusion] Jiasui cucumber had a good control effect on wheat scab and could reduce the 1000-grain weight loss of wheat. It is an effective bactericide for controlling wheat scab. It is recommended to be widely applied in the field of production. The application dosage is 1 500 g / hm2 It is advisable.
