我所于1978年开始乙磷铝的合成研究,并同各地农业单位协作,对黄瓜霜霉病(Pseudoperonospora cubensis)进行了一系列的药效试验。几年来的试验结果表明:乙磷铝对黄瓜霜霉病有明显的预防和治疗效果,是防治黄瓜霜霉病的良好药剂。同时还观察到乙磷铝在黄瓜体内有双向传导作用,为目前较为理想的新一代杀菌剂。 In 1978, I began the synthesis of C, and in collaboration with agricultural units around the country, conducted a series of efficacy trials on Pseudoperonospora cubensis. The experimental results over the past few years show that CEF has obvious preventive and curative effects on cucumber downy mildew and is a good medicament for controlling cucumber downy mildew. At the same time, it is also observed that BEP has a two-way conduction in the cucumber body, which is a new generation of bactericide currently ideal.
