Broad-spectrum fungicide for preventing and treating plant viruses and diseases and application of broad-spectrum fungicide

Abstract

The invention discloses a broad-spectrum fungicide for preventing and treating plant viruses and diseases. The broad-spectrum fungicide is prepared by combining two medicaments including cytosinpeptidemycin and amino-oligosaccharin. The broad-spectrum fungicide has the advantages that after cytosinpeptidemycin and amino-oligosaccharin are mixed in a certain proportion, the broad-spectrum fungicide has multiple effects of induction, prevention and treatment and has a remarkable synergistic effect; the broad-spectrum fungicide has a wide disease prevention spectrum and can be used for treating multiple diseases of host plants; the broad-spectrum fungicide is capable of inducing the plants to develop immunity, and the defense capability of the plants can be adequately utilized, so that the use of a chemical pesticide is reduced, the risk of generating the drug resistance is reduced, the ecological environment is protected, and the broad-spectrum fungicide can meet the requirements on green plant protection and ecological civilization construction.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a broad-spectrum fungicide for preventing and treating plant virus diseases and its application. Background technique [0002] Pyrimycin is a new antiviral agricultural antibiotic of cytidine nucleosides, produced by Streptomyces achygruscopicus, and has preventive and therapeutic effects on plant virus diseases. The product has low toxicity and low residue. It can destroy the structure of viruses, reduce the concentration of virions, and improve the ability of plants to resist viruses when used as a pesticide, so as to achieve the effect of preventing and treating viral diseases. It can also induce plants to produce resistance proteins and improve plant immunity. force. [0003] Amino oligosaccharins are agricultural chitosan oligosaccharides. By stimulating the plant's own immune response, the plant acquires systemic resistance, thereby playing a role in stress resistance, ...
