Description
Technical Field
The invention belongs to the field of pesticides, and relates to a bactericidal composition for preventing and treating agricultural diseases.
Background
In agricultural production processes, fungal diseases are a major factor affecting yield and quality. In order to improve the yield and quality of crops, pesticides for preventing and treating diseases need to be used, and a bactericide is one of the pesticides. Commonly used bactericides can be classified into amides, dihydroxy imides, strobilurins, triazoles, imidazoles, oxazoles, thiazoles, morpholines, pyrroles, pyridines, pyrimidines, quinolines, carbamates, organophosphates, antibiotics and the like according to the chemical structure type. The pyridine bactericide is a variety with a large using amount, and mainly comprises fluazinam and boscalid.
Fluazinam (Fluazinam), chemical name: 3-chloro-N- (3-chloro-5-trifluoromethyl-2-pyridyl) -a, a, a-trifluoro-2, 6-dinitro-p-toluidine has broad-spectrum bactericidal activity, has special effect on a plurality of gray mold caused by botrytis cinerea, and has good activity on diseases caused by pathogenic bacteria such as alternaria, phytophthora, monascus, sclerotinia, cladosporium and the like. Has no cross resistance with benzimidazoles, dicarboxyl imides and the existing bactericides on the market at present.
Boscalid (Boscalid), chemical name: 2-chloro-N- (4' -chloro diphenyl-2-yl) nicotinamide belongs to succinate coenzyme Q reductase inhibitors in mitochondrial respiratory chain, has strong inhibition capability on spore germination, and can be used for preventing and treating powdery mildew, gray mold, various rot diseases, brown rot, root rot and the like. Has no cross resistance with other bactericides.
However, long-term use of the same variety of bactericide can cause the pesticide resistance of the pathogenic bacteria of the crops to be generated and reduce the control effect. For example, crop pathogens have developed some resistance to fluazinam and boscalid. In order to cope with the drug resistance of pathogenic bacteria, the sterilization active compounds with different action mechanisms are compounded to be a better method.
Therefore, the compounding of the pyridine bactericide and other bactericides is a way to solve the drug resistance of germs.

First, bioassay example
Example 1, indoor virulence determination of the Compound pairing of ZJ10520 and fluazinam to Phytophthora capsici
Test subjects: phytophthora capsici (Phytophthora capsicii) is preserved in the unit strain room.
The test method comprises the following steps: refer to the hypha growth rate method of agricultural industry Standard NY/T1156.2-2006 of the people's republic of China. Each medicament is respectively treated by 5 dosages according to the content of effective components, the pathogenic bacteria are cultured by a PDA culture medium, when bacterial colonies grow to a culture dish, a puncher with the diameter of 5mm is used for punching bacterial blocks at the edges of the bacterial colonies, the bacterial blocks are moved to the center of a prepared toxic PDA culture medium by an inoculation needle, and then the bacterial blocks are placed in a 25 ℃ culture box for culture, and the treatment is repeated for 4 times. According to the growth condition of CK colonies, the diameter cm of each treated colony is measured by a caliper by adopting a cross method, and the corrected inhibition percentage is calculated. The EC of each drug was determined by linear regression analysis between the probability of inhibition and the logarithm of the series of concentrations50The co-toxicity coefficient (CTC) was then calculated according to the Sun cloud Peel method.
And (3) calculating the drug effect: two diameters were cross-measured per colony, and the average was used to represent colony size. The colony growth inhibition rate was determined according to the following formula: the colony growth inhibition ratio ═ g (blank colony growth diameter-agent-treated colony growth diameter) × 100/blank colony growth diameter.
The results were subjected to data analysis and statistics using the 3.11 professional edition to determine a regression line, EC50, and a correlation coefficient. EC50 for each treatment was converted to the Actual Toxicity Index (ATI) by the Sun cloud Peel (Y-P Sun); obtaining a Theoretical Toxicity Index (TTI) according to the mixture ratio of the mixture, and calculating the co-toxicity coefficient (CTC) of the mixture according to the following formula.
Theoretical virulence index of the mix (TTI) ═ A virulence index x A content in the mix (%)
+ B virulence index x B content in the mix (%)
If the co-toxicity coefficient is more than 120, the synergistic effect is shown; if the concentration is obviously lower than 100%, antagonism is indicated; between 100 and 120, the additive effect is shown.
