Abstract

The invention discloses a pesticide composition for effectively preventing cucumber downy mildew and belongs to the technical field of pesticide processing. The pesticide composition is characterized by containing 2.7-4.6 percent of alkaloid, 0.5-2.1 percent of a synergist and 92-97 percent of a solvent. According to the pesticide composition for effectively preventing the cucumber downy mildew, the alkaloid serves as an active ingredient, and a certain synergistic ingredient is added; prepared drugs can be used for efficiently preventing the incidence of the cucumber downy mildew disease and has a good inhibition effect on the incident disease; alkaloid ingredients can be automatically degraded in the environment, environment residues are eliminated, and the drug resistance of a crop is avoided. A pesticide preparation is easy to manufacture, safe, effective, convenient to use, low in production cost and good in environment compatibility.

Description

technical field [0001] The invention belongs to the technical field of pesticide processing, in particular to a pesticide composition for effectively preventing and treating cucumber downy mildew. Background technique [0002] Cucumber downy mildew is one of the major diseases in cucumber production. It is not only rapid in onset and serious in damage, but also widespread. During the onset period, it takes about a week to cause the disease in patches of plants, resulting in a tragic situation of 30-50% reduction in production. . Downy mildew not only seriously damages cucumbers, but also damages melon crops such as melons, pumpkins, loofahs, and bitter gourds. Downy mildew mainly occurs on the leaves, forming polygonal lesions. Many people can clearly identify them, but many people cannot make a clear diagnosis, especially when it is often confused with bacterial angular spot on the leaves. Often make mistakes. Here, I have to briefly describe that cucumber downy mildew m...
