Abstract
The invention provides a bio-pesticide with immune-inducing effect. According to parts by weight, its active ingredients include 0.2-12 parts of amino oligosaccharin and 1-20 parts of brassinolide. Preferably, the active ingredients of the biopesticide include 1-8 parts of amino oligosaccharin and 5-12 parts of brassinolide. The biopesticide of the present invention shows a synergistic effect within a certain proportioning range, and the bactericidal effect of the composition has been improved compared with that of a single agent; it can reduce the application dose per mu of active ingredients, the labor and cost of application, and also reduce the impact on Adverse effects of the environment and pesticide residues; the two active ingredients in the biopesticide of the present invention have different action mechanisms, and combined application can delay or overcome the drug resistance of pathogenic bacteria and prolong the service life of a single agent.
Description
technical field [0001] The invention relates to the field of pesticides, in particular to a biopesticide with immune induction and its application. Background technique [0002] Oligosaccharins, also known as chitooligosaccharides, oligomeric glucosamine or chitosan oligosaccharides, are the degradation products of natural chitin, and belong to a fungicide extracted from microbial metabolism with anti-disease effect. Amino oligosaccharins, as signal molecules (elicitors), can effectively induce plants to produce defense responses and activate plant systemic acquired resistance (SAR), for example, can induce a variety of resistance-related enzyme activities to increase, or make leaf cuticles Or the thickening of the cell wall forms a chemical or physical barrier to the invasion and expansion of pathogenic bacteria. It has a good control effect on diseases caused by various fungi, bacteria and viruses. [0003] Amino oligosaccharins have excellent control effects when crops ...
