Pest and disease damage resistant composition containing hypersensitive protein and application thereof

Abstract

The invention relates to the technical field of pesticides, and particularly provides a pest and disease resistant composition containing hypersensitive protein, which comprises an active component Aand an active component B, wherein the active component A comprises Harpin protein; the active component B is selected from: amino-oligosaccharin, lentinan, nitenpyram, pymetrozine, imidacloprid, acetamiprid, dicyclanil, ethiprole, butene-fipronil, mandipropamid, fluopicolide, boscalid, fluopyram, tebuconazole, epoxiconazole, cyproconazole, tetraconazole, difenoconazole, hexaconazole, flutriafol,prothioconazole, penconazole, myclobutanil, flusilazole, propiconazole, pyraclostrobin, garlicin, and ethylicin, wherein the weight ratio of the active component A to the active component B is 100:1- 1:100; wherein the amino-oligosaccharin comprises amino-oligosaccharin with high molecular weight and amino-oligosaccharin with low molecular weight.

Description

technical field [0001] The invention relates to the technical field of pesticides, more specifically, the invention provides a hypersensitive protein-containing anti-disease and insect pest composition and application thereof. Background technique [0002] In the actual process of agricultural production, fungi are the most important group of plant pathogens, and many important diseases such as downy mildew, late blight, blackleg and cotton blight are caused by fungi. Plant viruses are second only to fungi as pathogens. A virus is a non-cellular parasitic living organism composed of a nucleic acid molecule (DNA or RNA) and protein, and has strong infection and destructive power. As a parasitic organism of plants, plant viruses pose a great threat to the growth and development of plants and the survival and development of human beings. At present, there are more than 1,000 species of plant viruses that have been studied and named, many of which are important pathogens of cr...

Problems solved by technology

[0004] At present, the application of pesticides is the most effective means of preventing and controlling crop fungal or viral diseases, but the existing pesticide products can only prevent and control a single type of plant disease, and different types of diseases often need to be controlled by different pesticide varieties. The effect is poor, and the control period is long, the cost is high, and it will cause serious environmental pollution and disease resistance

The invention patent with the application publication number CN109744243A discloses the amino-oligosaccharin compound preparation for preventing and treating tobacco virus disease and its preparation method and application. Hypersensitive protein or dextran sugar or one or more of mixed fatty acids compounded, used in the prevention and treatment of tobacco virus disease, but did not mention the control effect on other plant virus diseases
