Problems solved by technology

At present, the prevention and control of the disease is mainly based on chemical means, but long-term large-scale application of chemical pesticides is likely to produce drug resistance and cause environmental pollution. Therefore, how to reduce the use of chemical pesticides and reduce environmental Pollution is an important problem to be solved in the field of peanut bacterial wilt control

Embodiment Construction

[0011] The technical solutions and beneficial effects of the present invention will be further described below in combination with test data and examples. The synergist of the present invention is obtained by mixing lactose and water at a mass ratio of 3:100 to prepare a lactose solution, then putting the lactose solution into a high-temperature and high-pressure sterilizer, treating it at 120°C for 30 minutes, and cooling it. The resulting potentiator was considered 100% parent drug.

[0012] An indoor toxicity test

[0013] (1) Pharmacy equipment:

[0014] Mix the above synergist with the amino oligosaccharin according to 1:0.5, 1:1, 1:2, 1:3, 1:4, 1:5, 1:6 to obtain mixed preparations 1#-7#.

[0015] (2) Toxicity determination method:

[0016] The turbidity method was used in the test to determine the toxicity of the above-mentioned synergist single dose, amino oligosaccharin single dose, and 1#-7# against peanut R. solanacearum. The specific measurement method is: inje...

Abstract

The invention relates to the technical field of prevention and treatment of peanut bacterial wilt, in particular to a method for preventing and treating peanut bacterial wilt, comprising the following steps: (1) preparing a synergist: mixing lactose and water at a mass ratio of 3:100 to prepare Lactose solution, then put the lactose solution into a high-temperature and high-pressure sterilizer, treat it at 120°C for 30 minutes, and obtain it after cooling; (2) The synergist and the amino oligosaccharin are in a mass ratio of 1:1-5 mixing to obtain a mixed preparation; (3) diluting the mixed preparation 300 times, and spraying it before the occurrence peak of bacterial wilt in peanut seedling stage. The invention has remarkable synergistic effect and can significantly prevent the occurrence of peanut bacterial wilt.

Description

technical field [0001] The invention relates to the technical field of crop disease prevention and control, in particular to a method for preventing and treating peanut bacterial wilt. Background technique [0002] Amino oligosaccharins, also known as oligochitosaccharides for agriculture, are low-toxic fungicides obtained by degrading chitin to chitosan and then degraded, or extracted by microbial fermentation. Amino oligosaccharin solution has antivirus, bactericidal and fungicidal effects, and can be widely used in the prevention and treatment of mosaic disease, small leaf disease, Spot, anthracnose, downy mildew, blight, blight, yellow dwarf, rice blast, bacterial wilt, soft rot and other diseases. But at present, the effect of amino oligosaccharin alone on peanut bacterial wilt is not good. [0003] Peanut bacterial wilt is a soil-borne bacterial disease caused by Ralstia solanacearum, and it is one of the most harmful, widely distributed, and most costly plant diseas...
