In agricultural production, the fertilizer can provide nutrients for crops, and the pesticide can prevent and control plant diseases and insect pests; after the fertilizer and the pesticide are mixed according to a certain proportion to prepare the fertilizer, the fertilizer can provide nutrients for crops and can prevent and treat target diseases and insect pests by one-time application.
Cucumber downy mildew is one of the most serious diseases that endanger cucumbers, and is harmful to more than 40 plants of the cucurbitaceae family in addition to infecting cucumbers. Cucumber downy mildew is caused by pseudoperonospora cubensis, can generate a large amount of spores, and can spread far by means of airflow. The cucumber downy mildew mainly damages the leaves of the cucumber, irregular water-immersed spots appear on the back of the leaves at the early stage of infection, the spots are gradually enlarged, gray black mildew layers appear on the back of the leaves with high humidity, the leaf margin is curled and dried, and yield reduction and harvest failure are caused when serious. Chemical agents are the most rapid, accurate and effective control methods, however, when the agents are used for control, the agents are easy to generate drug resistance after single use for a long time. Therefore, it is necessary to study a compound or a mixture for controlling cucumber downy mildew. At present, no report on the mixing of adding the hypsomyces oligospermis and the Zhongshengmycin into the water-soluble fertilizer is seen.
