摘要
1992～2002年研究表明,春季甜瓜霜霉病菌侵染病源基数大,6～8月降雨次数多、降雨量大,阴晴天气交替天数多,瓜田叶片结露时间长,种植感病品种是霜霉病发生和流行的主要因素。瓜秧稠密、瓜口止堂低洼凹陷、不利于通风透气,灌水较多,特别是雨前雨后灌水,均能加重病害发生。加强农业栽培措施,做好病害预测预报,选用72%霜霉必克、70%乙磷锰锌、72%杜邦克露等药剂可取得较好的防效。
This paper are showed that downy mildew of muskmelon in Xinjiang is one of the important diseases, caused by Pseudoperonospora cubensis (Berk.et Curt.)Rostov. The research in 1992-2002 showed that epidemic factors of this disease is such as the number of rainfall in June and August, the inoculum number of muskmelon downy mildew in spring, and the sensitive variety planted, the number of the weather alternating between sunshine and rain, etc.. Integrated management of this diseases have been suggested to apply the agricultural management, forecast of the disease, and effective fungicides.
