摘　　要：对新疆墨玉县核桃基腐病的发生规律进行了观测并对防治药剂开展了筛选试验。通过对和田墨玉县的核桃林地病害发生动态观测,发现核桃腐烂病在全年有两次发生高峰期,即春秋两季,其他时间腐烂病逐渐减弱。防治试验中选择8种常用药剂筛选对核桃基腐病防效较好的药剂和施药方式。在施药方式上刮除病斑涂药处理的防治效果优于划道和直接涂抹药剂,在使用药剂类型上单独使用杀菌剂效果好于杀菌剂与愈合剂混合使用,咪酰胺、阳离子水、拂蓝克是防治效果最优药剂,直接刮除病斑后涂抹防效分别可达100%,87.5%,85.7%。The occurrence law of walnut stalk rot were investigated and tested by control medicaments af-ter observing occurrence of walnut stalk rot in Moyu County,Xinjiang.It was found that there were two peaks of walnut stalk rot in winter and autumn of the whole year.The walnut stalk rot gradually reduced in some other time.The 7 kinds of better control medicaments and control methods were selected to control walnut stalk rot.The method for spreaking drugs on disease walnut tree epidermides was better efficient than that of directly spreading drugs after striking off scabs on the disease tree.The efficiency of using fun-gicides was more striking than that of mixed use of fungicides and healing agent.However,the control effect of mi amide,cationic water,brushed blue were optimal.It was concluded that the control effect of di-rectly spreading drugs on the walnut tree epidermides after striking off the scabs can reach 100%,87.5%, 85.7%.
