黄瓜白粉病是京郊黄瓜主要病害之一。近年来,随着保护地的发展,为害越来越重。为了探讨无公害防治,我们进行了农抗BO-10防治黄瓜白粉病试验,现小结如下。 1.农抗BO-10经多午试验,防治黄瓜白粉病,发病初期喷100单位,防效达90％以上,对黄瓜安全,残效期9天,储藏期可达2年。 2.农抗BO-10与多种农药试验比较的结果,农抗BO-10,浓度100单位和进口的化学农药25％粉锈宁2000倍效果相当,但超过农抗120、高脂膜、京2B、百菌清、滴涕、硫磷等农药。
Cucumber powdery mildew is one of the main diseases of cucumber in Beijing suburbs. In recent years, with the development of protected areas, the damage is more and more serious. In order to explore pollution-free control, we conducted a test of Agronomy BO-10 cucumber powdery mildew, are summarized as follows. 1. Agricultural anti-BO-10 after a multi-day test to control cucumber powdery mildew, the initial injection of 100 units, the anti-efficiency of more than 90% of cucumber security, residual 9 days, storage up to 2 years. 2. Compared with the results of a variety of pesticide trials, the results showed that agricultural anti-BO-10, with a concentration of 100 units and imported chemical pesticide 25% , Chlorothalonil, DDT, parathion and other pesticides.
