6种不同杀菌剂对小麦赤霉病的防治效果及对小麦产量的影响
|
摘要
[目的]筛选防治赤霉病的有效药剂。[方法]以济宁16为材料,研究了多菌灵、三唑酮、戊唑醇、咪鲜胺、丙森锌、唑醚·代森联6种杀菌剂对小麦赤霉病的田间防治效果。[结果]2013、2014年试验结果表明6种杀菌剂2次喷雾的平均病情指数防治效果均在60%以上,且产量增加显著,其中唑醚·代森联、咪鲜胺、丙森锌、戊唑醇的病指防效显著好于常规药剂多菌灵、三唑酮,可作为防治小麦赤霉病的药剂交替使用。[结论]为生产上小麦赤霉病的药剂防治提供了参考。
[Objective]The aim was to screen out efficient fungicides against wheat scab.[Method]Jining 16 was taken as material,and control effects of Carbendazim,Triadimefon,Tebuconazole,Prochloraz,Propineb,Pyraclostrobin-metiram on wheat scab in the field were studied.[Result] The test results of two years showed that the average disease index control effect of six kinds of fungicides was above 60% and the yield increased significantly. The control effects of Pyraclostrobin-metiram,Prochloraz,Propineb and Tebuconazole on wheat scab were better than that of conventional fungicides Carbendazim and Triadimefon. The four kinds of fungicides could be used as a medicament for preventing and controlling wheat scab used alternately.[Conclusion] The results provide reference for the chemical control of wheat scab.
