The invention discloses an oligochitosan-propineb composition used for plant protection. The composition is characterized in that the effective components of the composition are compounded by oligochitosan and propineb in weight ratio of 1: 99 to 99: 1. The compounded composition is used for plant protection, not only can prevent a plant from being infected by germs, but also can improve various resistances of the plant, alleviates later infection of the plant by the germs, and enables the pant to grow healthily, as a result, the yield and the quality can be improved.
Description
Technical field
The present invention relates to a kind of plant protection composition, relate in particular to a kind of plant protection complex composition that contains chitosan oligosaccharide and Propineb, belong to pesticide field.
Background technology
Chitosan oligosaccharide also is chitin, amino-oligosacchride, chitosan etc., be a kind of from the crust of the ocean crust biologies such as dried small shrimp, crab shell, extract have a multiple bioactive material.Be rich in chitin in the halobiontic crust, chitin is through deacetylated generation shitosan, and shitosan resolves into easily through enzymolysis or microwave treatment etc. and is absorbed by tissue, water miscible chitosan oligosaccharide.Studies show that in recent years, chitosan oligosaccharide have multiple biological function and are used gradually, comprising health care of food, beauty and skin care, bacteriostasis, preservation, plant induction of resistance etc.Aspect agriculture application study, find to use low polymerization degree, high deacetylated chitosan oligosaccharide to have obvious plant disease-resistant inductivity, particularly respond well to plant virus venereal disease evil.Chitosan oligosaccharide is biological product, nontoxic residue-free, and safety, environmental protection have broad application prospects in agricultural production.
Propineb, propineb is a kind of broad spectrum activity protective fungicide, and sterilization speed is fast, and the lasting period is long, and is effective to multiple germ, can be widely used in the control of plurality of plant diseases.
Summary of the invention
Technical problem to be solved by this invention provides the complex composition of a kind of chitosan oligosaccharide and Propineb; be used for plant protection; can avoid infecting of germ by protective plant; can improve again the various resistances of plant; alleviate plant later stage infecting by germ; and make plant growth healthy and strong, and improve output, improve quality.
