Description

Sterilization composition and application thereof
Technical Field
The invention belongs to the field of agricultural bactericides, and particularly relates to a bactericidal composition containing pyrimidine substituted pyrazole compounds and a bactericide and application thereof.
Background
Patent WO2016184378 discloses pyrimidine-containing substituted pyrazoles and their use, wherein compounds of the following general formula I-A, I-B are reported to have good activity against a variety of diseases.
Figure GDA0004121546920000011
Respiratory depressant bactericides, nucleic acid metabolism depressant bactericides, cell wall synthesis depressant bactericides, signal transduction depressant bactericides, cytoskeletal and motor protein inhibitor bactericides, sterol biosynthesis depressant bactericides, phospholipid synthesis depressant bactericides, cell wall synthesis depressant bactericides and methionine biosynthesis depressant bactericides are bactericides widely used in agricultural production and have remarkable control effects. Because the action site is single, 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 using bactericides, people often find that a medicament has good disease prevention effect in the early stage, but the medicament dosage is gradually increased along with the increase of the use times, and the medicament effect is slightly improved, and sometimes even the disease prevention effect is completely lost. The main reason is that the pathogenic bacteria group is changed, namely, part of pathogenic bacteria obtain drug-resistant plasmid through mutation to generate drug resistance, and dominant group is gradually formed in natural selection, so that the drug effect of the bactericide is reduced. At the same time, it is recognized that after the pesticide is applied, a portion of the pesticide may be scattered on the soil or into the air or along with rainwater and farmland drainage into rivers and lakes, causing environmental pollution. Therefore, there is an urgent need for pesticide products that have high efficacy, low dosage, little environmental pollution, and can delay the drug resistance of pathogenic bacteria.
The combined application of pesticides is an important means for delaying the generation of drug resistance of pathogenic bacteria and is also an effective method for reducing the pesticide dosage. The scientificity of the combined application of bactericides depends not only on the control object and the action mechanism, but also on the combined action property of the medicines after being mixed. Therefore, various restriction factors exist in developing a high-efficiency bactericide composition with complementary action and remarkable synergism, and the success rate is extremely low.
Disclosure of Invention
The invention aims to provide a synergistic bactericidal composition containing pyrimidine substituted pyrazole compounds and a bactericide and application thereof.
In order to achieve the above purpose, the invention adopts the technical scheme that:
a bactericidal composition comprises A, B two active components, wherein the weight ratio of the active component A to the active component B is 1:99-99:1;
wherein the active component A is one or more of pyrimidine-containing substituted pyrazole compounds or salts thereof; the active component B is selected from a bactericide.
The active component A is a compound shown in a general formula I-A or I-B or a salt thereof:

The liquid to be tested is sprayed on neat and consistent host plants (not inoculated before application and other medicines) cultured in a greenhouse on a crop sprayer, and disease inoculation is carried out after 24 hours. According to the disease characteristics, inoculating a disease plant to be subjected to temperature control and moisture preservation culture, then placing the inoculated plant into a climatic chamber for culture, and transferring the plant into a greenhouse for culture after the disease is infected; the disease plants which do not need to be subjected to the moisture preservation culture are inoculated and then directly transferred into a greenhouse for culture. And after the disease is sufficiently developed by contrast, carrying out disease investigation, and recording the total leaf number, the disease leaf number and the disease progression of the investigation.
The disease classification method comprises the following steps:
level 0: the whole plant is free from diseases;
stage 1: spot area is less than 5% of the whole leaf area;
3 stages: spot area spot 6-10% of the whole leaf area;
5 stages: spot area spot 11-20% of the whole leaf area;

Observed efficacy of active Components or compositions (C obs ) The pesticide effect evaluation general formula (correction control effect calculation formula) is used for calculation:
Figure GDA0004121546920000211
Figure GDA0004121546920000212
efficacy of "0" means that the level of infestation of the treated crop is the same as the level of infestation of the untreated control crop; efficacy of "100" means that the treated crop was not infested.
Expected efficacy of the composition (C exp ) The use of Abbott method (see Liu Xuemin et al, synergistic effect of bactericide blend, pesticide science and management, 2002, 23 (5), 12-15).
