Description

Sterilization composition containing benzovindiflupyr for unmanned aerial vehicle flight protection and preparation method and application thereof Technical Field The invention relates to the field of pesticides, in particular to a bactericidal composition containing benzovindiflupyr for unmanned aerial vehicle flight protection, and a preparation method and application thereof. Background The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Benzovindiflupyr (benzovindiflupyr), chemical name N- [9- (dichloromethyl) -1,2,3, 4-tetrahydro-1, 4-methylenenaphthalen-5-yl ] -3- (difluoromethyl) -1-methyl-1H-pyrazole-4-carboxamide, a pyrazole amide-based fungicide developed by the company N-up to 2012 and marketed. It belongs to the class of succinate dehydrogenase inhibitors (SDHI) and causes the death of tricarboxylic acid by interfering with the protein complex II on the respiratory electron transfer chain of the mitochondria of pathogenic bacteria (i.e. succinate dehydrogenase or succinate-ubiquinone reductase), leading to its death. The bactericide has no interactivity with triazole bactericides and methoxy acrylic acid ester bactericides, and can well prevent and treat various diseases such as wheat leaf blight, peanut black spot, rust disease, wheat powdery mildew, gray mold and the like. The structural formula is as follows: 。 Epoxiconazole (chemical name: 2RS,3 SR) -1- [3- (2-chlorphenyl) -2, 3-oxo-2- (4-fluorophenyl) propyl ] -1H-1,2, 4-triazole, an systemic triazole fungicide developed by Basiff company, inhibits the synthesis of ergosterol of pathogenic bacteria, blocks the formation of bacterial cell walls, has the characteristic of strong affinity fungal enzyme (14-demethylase), can be quickly absorbed by plants and is conducted to infected parts, so that disease infection is immediately stopped, has excellent lasting period, has good prevention effect on diseases such as leaf spot disease, powdery mildew, rust disease and the like on crops such as bananas, allium fistulosum, peanuts and the like, can improve the chitinase activity of the crops, and enhances the disease resistance of the crops themselves. Plant diseases pose a serious threat to agricultural production, and although the traditional bactericide can effectively control diseases, long-term single use of the traditional bactericide is easy to cause pathogenic bacteria to generate drug resistance, so that the control effect is reduced. However, the bactericidal composition containing benzovindiflupyr in the prior art is designed aiming at the traditional ground spray, and has the following problems: The formulation suitability is insufficient, the traditional benzovindiflupyr compound preparation is designed aiming at ground spray, and the problems of uneven droplet size, rapid evaporation, droplet drift and the like exist, so that the efficacy loss rate reaches more than 40%. The duration and the drug resistance risk are that the single benzovindiflupyr is easy to induce the resistance (such as mutation of subunit of succinic dehydrogenase) when used, the existing compound combination has limited synergistic effect, frequent administration is needed, and the cost and the drug resistance risk are increased. The environment protection is limited, traditional solvents such as aromatic hydrocarbons (such as dimethylbenzene and the like have high toxicity), the traditional solvents are easy to pollute non-target environment in the flying prevention, and the residue is high. The application scene is limited in that the prior art focuses on conventional diseases (such as wheat powdery mildew), lacks a rapid prevention and control scheme for explosive diseases (such as wheat scab and corn northern leaf blight), and is not suitable for the requirement of high-temperature high-humidity environmental stability. Therefore, development of a novel compound bactericide, delay generation of pathogen resistance, and improve the suitability of unmanned aerial vehicle flight protection technology and application scene innovation become hot spots of current pesticide research. Disclosure of Invention Object of the Invention The invention aims to provide a bactericidal composition containing benzovindiflupyr for unmanned aerial vehicle flight protection, and a preparation method and application thereof. The invention solves the problems of drug effect loss, resistance risk and environmental pollution of the compound preparation in unmanned aerial vehicle application in the prior art through dosage form suitability optimization, synergistic mechanism innovation and environmental protection promotion. Solution scheme In a first aspect, in order to achieve the purpose of the invention, the embodiment of the invent
