摘　　要：对山东省十几个县市花生茎腐病的调查研究结果表明,该病在花生主产区苗期发病率高,主要危害茎基部及分枝,并与土质、气候、栽培方式密切相关。一般有两次发病高峰期,第一次出现在6月中旬,全省花生主产区普遍发生。8月中下旬以后,随着植株衰老,病情指数缓慢上升进入第二个发病高峰期。田间防治试验表明,好力克+多菌灵、腈菌唑+多菌灵、甲基托布津和百泰防治效果分别为92.36%、76.74%、79.8%和78.35%。The results of investigation and study on peanut collar rot in Shandong Province showed that the disease had high incidence at seedling stage in the main producing areas of peanut and mainly harmed the basal stems and branches, which had close relation with soil, climate and cultivation ways. There were usually two occurrence peak periods and the first one commonly appeared in mid -June in the main peanut producing areas. After mid and late August, with the plant senescing, the disease index increased slowly and the second occurence peak began. The field test showed that the control effects of tebuconazole ＋ carbendazim, myclobu- tanil ＋ carbendazim, thiophamate - merhyl and ovraclostrobin - metiram were 92. 35% ,75. 74% ,79.8% and 78.35% respectively.
