Description

Bactericidal composition and application thereof
The application is a divisional application of Chinese invention patent application, the original application date is 11/20/2020, and the application numbers are as follows: 202011314120.0, title of invention: the bactericidal composition and the application thereof have the following publication numbers: CN 112825859A; the applicant filed a divisional application due to the singleness problem pointed out by the examiner of the original application.
Technical Field
The invention belongs to the field of agricultural fungicides, and particularly relates to a pyrimidine-containing substituted pyrazole compound and a bactericidal composition of a fungicide and application thereof.
Background
WO2016184378 discloses a pyrimidine-containing substituted pyrazole compound and application thereof, and reports that the compound shown as the following general formula I-A, I-B has good activity on various diseases.
Figure BDA0003653790080000011
The bactericide of the respiratory inhibitor class, the bactericide of the nucleic acid metabolism inhibitor class, the bactericide of the cell wall synthesis inhibitor class, the bactericide of the signal transduction inhibitor class, the bactericide of the cytoskeleton and the kinetin inhibitor class, the bactericide of the sterol biosynthesis inhibitor class, the bactericide of the phospholipid synthesis inhibitor class, the bactericide of the cell wall synthesis inhibitor class and the bactericide of the methionine biosynthesis inhibitor class are bactericides which are widely used in agricultural production and have outstanding prevention and treatment effects. Due to the single action site, the field efficacy of part of varieties is obviously reduced after long-term repeated use. The multi-site inhibitor bactericide is a broad-spectrum protective bactericide, but the bactericide has poor therapeutic activity and large field dosage.
In the practice of applying bactericides, people often find that one medicament has a good disease prevention effect in the initial stage, but the dosage is gradually increased along with the increase of the use times, the medicament effect is slightly improved, and sometimes the disease prevention effect is even completely lost. The main reason is that the pathogenic bacteria population changes, namely part of pathogenic bacteria obtain drug-resistant plasmids through mutation to generate drug resistance, and the dominant population is gradually formed in natural selection, so that the drug effect of the bactericide is reduced. Meanwhile, it is also recognized that after the pesticide is applied, a part of the pesticide may be scattered on the soil or dissipated into the air, or may flow into rivers and lakes along with rainwater and farmland drainage, causing environmental pollution. Therefore, pesticide products which have high pesticide effect, small dosage and less environmental pollution and can delay the drug resistance of pathogenic bacteria are urgently needed.
The pesticide combination application is an important means for delaying the generation of drug resistance of pathogenic bacteria and is an effective method for reducing the pesticide dosage. The scientificity of the combined application of the bactericides depends on not only the control objects and the action mechanism, but also the combined action property after the medicaments are mixed. Therefore, the development of a high-efficiency bactericide composition with complementary action and remarkable synergism has a plurality of restriction factors and has extremely low success rate.
