Resveratrol：
In addition, the 10% resveratrol parent drug and 0.2% resveratrol soluble solution registered by Inner Mongolia Qingyuanbao Biotechnology Co., Ltd. are the first registered products in my country. The chemical full name of resveratrol is 3,5,4′-trihydroxystilbene, or trihydroxystilbene for short. Resveratrol is a plant-derived fungicide. It is a natural plant antitoxin. When grapes and other plants are affected by unfavorable conditions such as fungal infection, the resveratrol in the corresponding parts will accumulate to deal with the unfavorable conditions. Trihydroxystilbene can be extracted from plants containing resveratrol such as Polygonum cuspidatum and grapes, or it can be synthesized artificially.
Relevant field trials showed that Inner Mongolia Qingyuan Bao 0.2% trihydroxystilbene liquid, with an effective amount of 2.4 to 3.6 g/hm2, has a control effect of about 75% to 80% against cucumber gray mold. Two weeks after cucumber transplantation, spraying should be started before or at the initial stage of disease occurrence, with an interval of about 7 days, and spraying twice
