摘　　要：针对近年来河北省核桃果实病害越来越严重的状况,选取7个药剂组合进行田间防控试验。结果表明:7个处理对核桃果实病害防效差异显著,5月喷施20%叶枯唑500倍和6、7月喷施20%叶枯唑500倍+80%代森锰锌600倍的组合防治效果最好,其次是5~7月均喷施等量式波尔多液,这两种药剂可以轮换使用,防止产生耐药性。Based on the increasingly serious situation of walnut fruit diseases in Hebei Province in recent years,seven pesticide combinations were selected for field control experiments.The results showed that the control effects of 7 pesticide combinations on walnut fruit diseases were significantly different.The combination of 20% bismerthiazol 500 times and 20% bismerthiazol 500 times +80% mancozeb 600 times had the best control effect,followed by the equal amount of Bordeaux liquid.These two pesticide combinations can be used alternately to prevent drug resistance.
