鞍山地区大棚黄瓜一般在6月中旬发生白粉病,罹病后7天左右整棚叶片逐渐干枯死亡,导致瓜秧提早落架而减产。1985年鞍山市郊千山、东鞍山、沙河等乡的旧堡、高占屯等村塑料大棚黄瓜,白粉病普遍严重。病叶率都在99％以上。 目前,国内药剂防治大都采用粉锈宁、甲基托布津、农抗120、百菌清、敌硫酮、代森铵、石硫合剂等药剂防治。为了进一步扩大生物药剂使用品种,1985年从中国农业科学院原子能利用研究所引进BO-10
Greenhouse cucumber in Anshan generally occurred in mid-June powdery mildew, sick leaves around the disease after 7 days gradually dry death, leading to melon seedling early fall frame and yield. 1985 Anshan suburbs Qianshan, East Anshan, Shahe and other township of the old fort, Gao Zhantun other village plastic shed cucumbers, powdery mildew is generally serious. Sick leaf rate of more than 99%. At present, most of the domestic pharmaceutical control and prevention and treatment of triadimefon, thiophanate-methyl, agricultural anti-120, chlorothalonil, propionethione, generation ammonium, lime sulfur mixture and other agents. In order to further expand the variety of biological agents used in 1985 from the Institute of Atomic Energy Chinese Academy of Agricultural Sciences introduced BO-10
