Abstract
The embodiment of the invention relates to a pesticide composition and application thereof, and relates to the field of pesticides, wherein active ingredients in the pesticide composition comprise fluxapyroxad, pyraclostrobin and prothioconazole, and the weight ratio of the fluxapyroxad, the pyraclostrobin and the prothioconazole is 1: (0.1-30): (0.1-30), optionally 1: (0.5-5): (0.5-5). The active ingredients of the fluxapyroxad, the pyraclostrobin and the prothioconazole in the pesticide composition are combined and used according to a proportion, so that the pesticide composition has a more remarkable control effect, the diseases are more overlapped in disease occurrence seasons, the control effect is obvious, the pesticide amount can be reduced, the effect duration is long, the cost is reduced, the pollution of pesticide residues to the environment is reduced, and the generation of the drug resistance of plant diseases can be delayed.
Description
Technical Field
The invention relates to the field of pesticides, and particularly relates to a pesticide composition and application thereof.
Background
The fluxapyroxad is a carboxamide bactericide developed by Pasteur, has high efficiency, broad spectrum, long duration, systemic conductivity and the like, and the mechanism of the fluxapyroxad acts on the junction succinate dehydrogenase which is connected with oxidative phosphorylation and electron transfer in a bacterial body to cause tricarboxylic acid cycle disorder and block the energy metabolism of the tricarboxylic acid cycle disorder, so that the germination of pathogenic bacteria spores is inhibited, and the growth of dental canals and mycelia is caused to die, thereby preventing and treating diseases.
Fluxapyroxad is the trade name of the compound 3- (difluoromethyl) -1-methyl-N- (3 ',4',5' -trifluorobiphenyl-2-yl) pyrazole-4-carboxamide, fluxapyroxad, formula C 18 H 12 F 5 N 3 O, relative molecular mass 381.3, CAS number 907204-31-3, and its structural formula is shown in formula (I):
pyraclostrobin is a methoxy acrylate bactericide developed by BASF corporation, has the action mechanism of a mitochondrial respiration inhibitor, namely has the functions of protection, treatment and leaf permeation and conduction by preventing electron transfer in cytochrome synthesis, and has the advantages of wide bactericidal spectrum, high activity, low toxicity and the like.
Pyraclostrobin is a compound N- [2- [ [1- (4-chlorophenyl) pyrazol-3-yl]Oxymethyl radical]Phenyl radical]-methyl N-methoxycarbamate, sold under the name pyraclostatin, of formula C 19 H 18 ClN 3 O 4 The molecular weight is 387.8, the CAS number is 175013-18-0, and the structural formula is shown as a formula (II):
prothioconazole is a triazolethione bactericide developed by Bayer companies, has good systemic activity, can protect and treat, has long lasting period and is safe to crops. The action mechanism is that demethylation on 14-site of lanosterol precursor or 2,4 methylene dihydro lanosterol in the fungus is inhibited, and active ingredients can be simultaneously transferred upwards and downwards in crops, so that the composite has good control effect on un-sprayed or new parts.
Prothioconazole is the trade name for the compound 2- [2- (1-chlorocyclopropyl) -3- (2-chlorophenyl) -2-hydroxypropyl ] -1,2-dihydro-3H-1,2,4-triazole-3-thione, available under the english trade name prothioconazole, of the formula C14H15Cl2N3OS, with a relative molecular mass of 344.3, cas number 178928-70-6, and has the structural formula shown in formula (III):
at present, bactericide pesticide varieties for preventing and treating field diseases have large using amount, the diseases are frequently overlapped in disease occurrence seasons, multiple pesticide application is needed, a single chemical pesticide bactericide is used for preventing and treating plant diseases for a long time in a large amount, the pesticide resistance is easy to generate, and the service life of the pesticide is influenced. Therefore, the development of a novel bactericidal pesticide is urgently needed.
Disclosure of Invention
Object of the Invention
In order to solve the technical problems, the invention aims to provide a quick-acting, durable, low-toxicity, low-residue and safe pesticide composition and application thereof, wherein the pesticide composition can effectively prevent and treat field diseases and improve crop yield.
Solution scheme

1.3 data analysis
The co-toxicity coefficient (CTC value) of various compound agents is determined by adopting an indoor toxicity determination method (according to the Sun Yunpei method) and through indoor toxicity determination, and the synergy of the agents is judged according to the CTC value. CTC is obviously greater than 100 and is synergistic, is obviously less than 100 and is antagonistic, and is close to 100 and is additive. However, in the actual production process, once thought, the synergistic effect is achieved when the CTC is more than or equal to 120, the antagonistic effect is achieved when the CTC is less than or equal to 80, the additive effect is achieved when the CTC is more than 80 and less than 120, and the obvious synergistic effect is achieved when the CTC is more than or equal to 200.
Actual virulence index (ATI) = standard agent LC 50/mixed agent LC50 x 100
Virulence index (TTI) = standard agent LC 50/test agent LC50 x 100
Theoretical virulence index (TTI) = a medicament ATI x the percentage of a in the mix + B medicament ATI x the percentage of B in the mix + C medicament ATI x the percentage of C in the mix calculated on three technical single doses;
calculating three technical single agents of a binary mixed agent and another single agent: 1) Theoretical virulence index (TTI) = (a + B) agent ATI x the percentage of (a + B) in the mixture + C agent ATI x the percentage of C in the mixture; 2) Theoretical virulence index (TTI) = (a + C) agent ATI x the percentage of (a + C) in the mixture + B agent ATI x the percentage of B in the mixture; 3) Theoretical virulence index (TTI) = a medicament ATI x the percentage of a in the mix + (B + C) medicament ATI x the percentage of (B + C) in the mix;
