Problems solved by technology

The mildew spots are scattered separately in the early stage, and then combined to form a large mildew spot, which can even cover the whole leaf, seriously affecting photosynthesis, disturbing normal metabolism, causing premature aging, and loss of yield

Abstract

The invention relates to emulsion in water used for preventing and treating powdery mildew of cucumbers. The emulsion in water comprises lentinan, plant activator proteins, drazoxolon, garlic oil, sodium alginate, glycerin, C8-10 fatty alcohols, benzyl dimethyl phenol polyoxyethylene ether, cyclohexanone and deionized water. The emulsion in water has the advantages that the emulsion in water is a compound pesticide used for preventing and treating powdery mildew of cucumbers and has obvious synergistic effects and has the effect of obviously reducing the usage amount of active ingredients after lentinan, plant activator proteins and drazoxolon are compounded; and the emulsion in water has the effect of effectively reinforcing the functions of preventing and treating the powdery mildew of cucumbers, takes effect quickly, has long duration, does not affect non-target crops and has obvious yield-increasing effects on cucumbers.

Description

technical field [0001] The invention relates to an emulsion in water for preventing and treating cucumber powdery mildew, belonging to the field of pesticides. Background technique [0002] Lentinan is an effective active ingredient extracted from high-quality mushroom fruiting bodies. It is a host immune enhancer. Lentinan has the functions of anti-virus, anti-tumor, regulating immune function and stimulating the formation of interferon. Lentinan is a component that improves plant immunity. Its molecular weight exceeds 10,000 polysaccharides, mainly β-1,3 glucan, and contains a small amount of xylose and mannose. Lentinan was mainly used in the field of medicine at the earliest. With the deepening of people's research on biological pesticides, lentinan has been used in the field of pesticides. [0003] Plant activator protein is a class of thermostable protein elicitor isolated from fungi that can promote plant growth and improve its resistance. The molecular weight of th...
