Problems solved by technology

Amino oligosaccharides have the disadvantage of not being ideal for the control of infected diseases due to their slow action in the actual use process.
[0005] At present, there is no report on the prevention and treatment of plant diseases by isothiazolones. After experimental research by Shaanxi Shanggelu Biological Science Co., Ltd., it was found that it has good control effect on rice bacterial blight and apple tree rot, and has good quick effect. characteristics, but it has the disadvantages of short duration of action, frequent use of medication, and high cost of use; amino-oligosaccharins have the advantages of inducing plant antibodies, stimulating plant growth, and long duration of action, but they have slow quick-acting properties, which are harmful to those already in use. Infested disease control effect is not ideal

Embodiment 1

[0018] Weigh 12% isothiazolinone, 0.1% oligosaccharin, 3% TX-10, deionized water and add to 100% by weight. The above raw materials are mixed, stirred and dissolved completely to prepare a 12.1% isothiazolinone·aminooligosaccharin aqueous solution.

[0019] In this embodiment, the weight ratio of isothiazolinone to amino oligosaccharin can vary from 0.01 to 140:1, and the total weight content of the two is still 12.1%, forming a new embodiment.

Embodiment 2

[0021] Weigh 10% isothiazolinone, 0.2% amino oligosaccharin, 0.5% Nongru 500#, 3% Nongru 700#, deionized water and add to 100% by weight. The above raw materials are mixed, stirred and dissolved completely to prepare a 10.2% isothiazolinone·aminooligosaccharin aqueous solution.

[0022] In this embodiment, the weight ratio of isothiazolinone to amino oligosaccharin can be changed between 0.01-140:1, and the total weight content of the two is still 10.2%, forming a new embodiment.

Embodiment 3

[0024] Weigh 8% isothiazolinone, 0.5% amino oligosaccharin, 3% penetrant JFC, deionized water and add to 100% by weight. The above raw materials are mixed, stirred and dissolved completely to prepare a 10.2% isothiazolinone·aminooligosaccharin aqueous solution.

[0025] In this embodiment, the weight ratio of isothiazolinone to amino oligosaccharin can vary from 0.01 to 140:1, and the total weight content of the two is still 8.5%, forming a new embodiment.

Abstract

The invention discloses an isothiazolone-containing bactericidal composition and application thereof, and in particular relates to a bactericidal composition containing isothiazolone as a first active component and amino-oligosaccharin as a second active component, and application thereof. The weight ratio of the isothiazolone to the amino-oligosaccharin in the composition is 0.01-140:1, preferably 0.05-5:1. The composition has the advantages that the composition is reasonable in components, good in bactericidal effects and low in drug-using cost; the activity and bactericidal effects of the composition have remarkable synergy instead of simply adding the activity of each component; and the composition is quick in response and long in lasting effects, slows down resistance generation, has good safety to crops, and meets the requirement of pesticide preparations on safety. The prevention and control effect of the composition on the crops diseases of fruit trees, grain, melons, fruits and vegetables reaches 80.28 to 91.65 percent.

Description

technical field [0001] The invention relates to a bactericidal composition containing isothiazolinone, in particular to a bactericidal composition containing a first active component isothiazolinone and a second active component aminooligosaccharin. Background technique [0002] Isothiazolinone consists of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI), trade name: CIT / MIT, Kathon, Kathon, Kathon, isothiazolinone, CAS NO: 26172-55-4 / 2682-20-4, molecular formula: C 4 h 5 NOS / C 4 h 4 ClNOS, molecular weight: 115.16 / 149.59. [0003] Isothiazolinone is a broad-spectrum, high-efficiency, low-toxicity, non-oxidative biocide that kills bacteria and algae by breaking the bonds of proteins. After contacting with microorganisms, isothiazolones can quickly and irreversibly inhibit their growth, resulting in the death of microbial cells, and have strong inhibitory and killing effects on common bacteria, fungi, algae, etc. High biocidal efficie...
