塑料大棚里,黄瓜霜霉病发生普遍,一般减产20%,严重者可达60%以上。目前生产上多使用代森锌、乙磷铝、百菌清、退菌特、瑞毒霉等杀菌荆进行喷雾防治。在大棚内喷药是一项繁重的体力劳动,每喷1亩地需3—4个小时,且药液不易喷洒均匀,影响防治效果;更为严重的是增加棚内湿度,导致霜霉病和其它病害的发生。为此,我院植保所农药室研制了一种百菌清烟雾片,经我们试验、示范表明其防治效果高达90%以 Plastic greenhouses, cucumber downy mildew occurs generally, the general reduction of 20%, in severe cases up to 60%. At present, the production of more use of deuterin, phosphorus, aluminum, chlorothalonil, off special bacteria, such as fungi Jing Rui spray spray prevention and control. Spraying in the greenhouse is a heavy manual labor, spraying 1 mu of land need 3-4 hours, and the liquid spray is not easy, affecting the control effect; more serious is to increase the shed humidity, leading to downy mildew And other diseases happen. To this end, the Institute of Pesticide Protection Institute of our hospital developed a chlorothalonil aerosol tablets, after our test, the demonstration shows that the control effect of up to 90%
