七种杀菌剂对马铃薯晚疫病的影响

Effects of 7 Fungicides on Late Blight of Potato

试验通过研究7种杀菌对马铃薯晚疫病的影响,旨在筛选出对马铃薯晚疫病防效较好的杀菌剂。试验结果表明:相对于药剂对照和清水对照,50%氟啶胺悬浮剂、96%烯酰吗啉(原药)和40%琥·铝·甲霜灵可湿性粉剂均能极显著的减轻马铃薯晚疫病的发生,50%咪鲜胺锰盐可湿性粉剂能显著的减轻马铃薯晚疫病的发生,其他药剂的防治效果不显著。相对于清水对照,各药剂均能显著的提高马铃薯的产量。50%氟啶胺悬浮剂、60%唑醚·代森联水分散粒剂和45%代森铵水剂,相对于其他药剂和对照,能够显著的提高马铃薯的产量。不同处理对马铃薯植株株高、茎粗、叶宽和叶长的影响没有显著性差异。马铃薯实际生产中,建议用50%氟啶胺悬浮剂、96%烯酰吗啉(原药)、40%琥·铝·甲霜灵可湿性粉剂和50%咪鲜胺锰盐可湿性粉剂轮换用药和混合用药,可以获得较为理想的防治效果。

In this experiment,the effects of7kinds of bactericidal bacteria on potato late blight were studied.Experimental results show that compared with the drug control and water control,suspending agent,50%fluazinam suspending agent,96%dimethomorph(active compound)and40%Rubber Hu fatty acid·phosethyl-al·metalaxyl wp can significantly reduce the occurrence of potato late blight,50%prochloraz manganese salt wp can significantly reduce the occurrence of potato late blight,the control effect of other agents was not significant.Compared with the control of water,each agent can significantly increase the yield of potato.Compared with other agents and controls,50%fluazinam suspending agent,60%azole ether·polyram water dispersible granule and45%ambam water aqua can significantly increase potato yield.There was no significant difference in the effects of different treatments on plant height,stem diameter,leaf width and leaf length.In the actual production of potatoes,it is recommended to use the50%fluazinam suspending agent,96%oleyl morpholine(original drug),40%Rubber Hu fatty acid·phosethyl-al·metalaxyl wp and50%prochloraz manganese salt wp to alternate and mix,so as to achieve a more ideal control effect.
