Problems solved by technology

There is a problem of long-term, single, and large-scale use of this type of medicament, which makes the bacteria produce strong resistance, which is not conducive to the further improvement of drug efficacy; The amount of chemicals and the number of sprays not only increase the labor intensity, but also increase the cost of prevention and treatment
Extensive use of pharmaceuticals will inevitably lead to an increase in the amount of residues in the environment, causing pollution to the environment

Embodiment 1

[0035] Example 1 Preparation of 10.5% boscalid·epiconazole ultra-low volume liquid

[0036] Weigh the components according to the following proportions: 0.5kg boscalid, 10kg epoxiconazole, 0.5kg calcium alkylbenzene sulfonate, 0.5kg alkylphenol polyoxyethylene ether, 10kg N-methylpyrrolidone, 10kg three Propylene glycol butyl ether, 68.5kg terpineol, spare. First put into the reactor, turn on the reactor agitator, add boscalid and epoxiconazole to the reactor under stirring conditions, and stir until the reactants are completely dissolved; after the reactants are completely dissolved, add to the reactor The remaining components are added to the mixture, and the stirring is continued for 15-60 minutes to obtain a uniform and transparent oily product, thereby obtaining the present invention.

Embodiment 2

[0037] Example 2 Preparation of 13% boscalid·epiconazole ultra-low volume liquid

[0038] Weigh the components according to the following proportions: 10kg boscalid, 3kg epoxiconazole, 5kg calcium alkylbenzene sulfonate, 10kg fatty alcohol polyoxyethylene ether, 20kg N-methylpyrrolidone, 10kg methyl oleate, 42kg soybean oil, spare. First put N-methylpyrrolidone into the reactor, turn on the reactor agitator, add boscalid and epoxiconazole to the reactor under stirring conditions, and stir until the reactants are completely dissolved; after the reactants are completely dissolved , And then add the remaining components to the reaction kettle, continue to stir for 15-60 minutes, to obtain a uniform and transparent oily product, that is, the present invention is obtained.

Embodiment 3

[0039] Example 3 Preparation of 8% boscalid·epiconazole ultra-low volume liquid

[0040] Weigh the components according to the following proportions: 3kg boscalid, 5kg epoxiconazole, 5kg calcium alkylbenzene sulfonate, 3kg castor oil polyoxyethylene ether, 20kg N-methylpyrrolidone, 10kg methyl oleate, 54kg soybean oil, spare. First put N-methylpyrrolidone into the reactor, turn on the reactor agitator, add boscalid and epoxiconazole to the reactor under stirring conditions, and stir until the reactants are completely dissolved; after the reactants are completely dissolved , And then add the remaining components to the reaction kettle, continue to stir for 15-60 minutes, to obtain a uniform and transparent oily product, that is, the present invention is obtained.

Abstract

The invention discloses an ultra-low volume liquid agent containing boscalid and triazole fungicide, a preparation method and an application of the liquid agent, aiming at solving the problems that as an ultra-low volume solvent requires characteristics of low release, high flash point, good active compound solubility, small crop medicine harm and low viscosity, ordinary components cannot meet corresponding requirements of the ultra-low volume solvent, a small varieties of ultra-low volume liquid agents are developed at present, and moreover, as a conventional medicine which takes triazole as the active component is separately and greatly used for a long time, germs have strong resistance and the medicine effect is hard to be further improved. The ultra-low volume liquid agent disclosed by the invention comprises boscalid, triazole fungicide and the like. After screening and experiment of a long time, the ultra-low volume liquid agent containing boscalid and triazole fungicide is prepared, the liquid agent takes boscalid and triazole fungicide as effective components, and through cooperation of the components, the liquid agent has the advantages of synergistic interaction, rapid effect, long lasting time, rain wash resistance, water conservation and labor conservation.

Description

Technical field [0001] The invention relates to the field of pesticides, in particular to an ultra-low volume liquid containing boscalid and triazole fungicides, and a preparation method and application thereof. Background technique [0002] Ultra-low-volume liquids are solvents with low volatility, high flash point, good solubility to the original drug, low phytotoxicity to crops, and low viscosity. They are not mixed with water during application, but use ultra-low-volume spray equipment. , Low-volume spray equipment or ultra-low-volume electrostatic spray equipment for direct application. Ultra-low volume solvent. During the spraying process, since the droplets do not contain highly volatile components, the size and quality of the droplets do not change significantly from the process of leaving the spraying device to the target, which can effectively reduce volatilization and flow. At the same time, the droplets are small and uniform, which meets the requirements of "best bio...
