摘　　要：通过温室盆栽和田间大棚栽培试验研究了Men-myco-93-63生物制剂对黄瓜和甜瓜白粉病的防治效应。盆栽黄瓜试验结果显示:先施用100、200倍液的生物制剂,再接种病原菌,可显著提高黄瓜的抗病能力,降低发病率,防效达到89.9%和77.0%;而先接种,再喷药100、200倍液的生物制剂,在一定程度上能抑制病原菌的扩展,也具有防治作用,防效达到80.8%和54.5%。田间大棚栽培甜瓜的试验结果显示:200、400倍液的生物制剂对甜瓜白粉病的防效与清水对照相比,差异都达到显著水平,400倍液防效高于化学药剂阿米西达。这表明该生物制剂对于防治瓜类白粉病有很大的推广价值。The control effects of Men-myco-93-63 biological preparation on powdery mildew of cucumber and melon were tested in greenhouses and fields, respectively. The results of pot experiment demonstrated that inoculation of pathogenic bacteria after spraying 100-fold and 200-fold of biological preparations can effectively enhance the disease resistance of cucumber and reduce the incidence of disease, and the control efficacy can reach 89.9% and 77.0%, respectively; while inoculation of pathogenic bacteria before spraying 100-fold and 200-fold of biological preparations can also inhibit the extending of pathogenic bacteria at certain level, and the control efficacy can reach 80.8% and 54.5%, respectively. The field investigation results showed that the difference between control efficacy for 200-fold and 400-fold of biological preparations and control （pure water） on melon powdery mildew reached significant level; the control efficacy of 400-fold of biological preparation was higher than that of chemical agent Azoxystrobin. Therefore, the biological preparation has high extending value for controlling powdery mildew of cucurbits and melon.
