Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a sterilization composition containing oxathiapiprolin and carboxin.
Background
The fluorothiazolepyrietophenone is the first piperidyl thiazole isoxazoline bactericide developed by DuPont, has unique action sites on oomycete pathogenic bacteria, and achieves the bactericidal effect by inhibiting oxysterol binding protein (OSBP). It has effects of preventing, treating and inhibiting spore production; it has no cross resistance with the existing bactericide. However, the fluorothiazole pyrithylone has a single action site, has medium-high level resistance risk and needs to be subjected to resistance management.
The carboxin belongs to a selective systemic fungicide and is suitable for rust diseases, smut diseases and the like of crops such as wheat, rice, cotton, peanuts, soybeans, vegetables, corns, sorghum and the like caused by rust bacteria and smut.
The synergistic bactericidal composition can greatly improve the control effect, reduce the dosage and reduce the cost, can also avoid the generation of resistance of plant pathogenic bacteria and delay the generation speed of the resistance, and is an effective way for solving the problems of the resistance and the cost when the pesticide is used singly. Therefore, the development of the bactericidal composition with the synergistic effect on fungal diseases is of great significance. Related reports of compounding the oxathiapiprolin and the carboxin are not found in the prior art.

Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Example 1 indoor toxicity determination of Fluroxypyrithylone and carboxin combination on wheat stripe rust
Test subjects: stripe rust of wheat
The test is carried out by adopting a potting method, when the first leaves of the wheat seedlings are completely unfolded, inoculation is carried out, medicines are applied after 24 hours of moisture preservation, disease investigation is carried out after the medicines are pro-medicines, the prevention and treatment effects are calculated according to the respective standards of wheat stripe rust by using the disease index, the DPS data processing software is used for carrying out statistical analysis, the EC50 of each medicine is calculated, and the co-toxicity coefficient (CTC) is calculated according to the Sun cloud Peel method. The specific measurement results are shown in Table 1.
When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
Measured virulence index (ATI) ═ standard agent EC 50/test agent EC50 x 100
Theoretical virulence index (TTI) ═ A agent virulence index x percent of A in the mixture + B agent virulence index x percent of B in the mixture
Co-toxicity coefficient (CTC) × 100 [ measured toxicity index (ATI) of the mixture)/Theoretical Toxicity Index (TTI) of the mixture ].
TABLE 1 virulence determination of Fluothiazolopyridone and carboxin for wheat stripe rust
From the above table, the weight ratio of the oxathiapiprolin to the carboxin is 1:30-30:1, so that the synergistic effect on the wheat stripe rust is achieved, and the control effect on the wheat stripe rust is improved.
Example 2 field control of Fluroxypyrithylone and carboxin against wheat stripe rust
Test subjects: wheat stripe rust; the method is arranged in a wheat stripe rust susceptible area in a test, and the method for applying the pesticide by spraying the stem leaves is carried out for 1 time at the initial stage of the wheat stripe rust. Sampling is carried out at 5 points on a double diagonal line of each cell, 20 plants are randomly selected at each point, each plant is investigated for 3 times, the disease condition base is investigated before the drug, the disease condition base is investigated for prevention and treatment effects in 7 days and 14 days after the drug, and the prevention and treatment effects are calculated according to the disease condition index.
