Sterilizing combination containing chunleimeisu and mushroom protein polysaccharide and application thereof

Abstract

The invention belongs to the technical field of pesticide, and particularly relates to a compound sterilizing combination containing chunleimeisu and mushroom protein polysaccharide and the application thereof in field of prevention and treatment of crop bacterial and fungus diseases and growth adjusting function. According to the combination, the weight ratio of mushroom protein polysaccharide to chunleimeisu is 1:1 to 1:100, and the combination has the effect of efficacy enhancement through compounding, has a wide application range, low cost, good effects and more obvious treatment effects, and belongs to ideal agent for preventing and treating various bacterial and fungus diseases of crops, such as vegetables, melons, fruits, rice and the like. The combination has strong permeability and moves in plant bodies, is quick to become effective after being sprayed, rainwash resistant and long in lasting period, and can ensure that the color of leaves of melons to which the combination is applied is thick and green and prolong the harvest time. The combination is applied to rice, potatoes, cucumbers, celeries, sorghums, peppers, kidney beans, citruses and fruit trees.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a bactericidal composition compounded with kasugamycin and mushroom proteoglycan, and its application in preventing and treating fungal diseases of crops. Background technique [0002] Kasugamycin: [0003] (kasugamycin; kasumin; kasurabcide; kasumin-bordeaux; KSM) chemical name 5-amino-2-methyl-6-(2,3,4,5,6-hydroxycyclohexyloxy)tetrahydropyran-3- base) amino-α-iminoacetic acid, which belongs to organic heterocyclic fungicides. Melting point (°C): 236-239 (decomposition); hydrochloride: 202-204 (decomposition) Properties: pure product is white crystal; hydrochloride is white needle or flaky crystal, with sweet taste. Dissolution: The pure product is insoluble in organic solvents, 12.5% ​​(W / V) dissolved in water at 25°C; hydrochloride is easily soluble in water, but insoluble in methanol, ethanol, acetone, benzene and other organic solvents. [0004] Kasugamycin is a metabo...

Problems solved by technology

[0008] Due to the long-term use of the above two agents alone, it is easy to lead to the generation of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a large increase in dosage, shortened spraying cycle, and poor use effect, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products also increase, which affects the health and normal survival of humans and animals. The compound use of kasugamycin and mushroom proteoglycans to prevent and control crop diseases, Not yet reported at home and abroad
