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 · epoxiconazole ultra-low volume liquid

[0036] Weigh each component according to the following ratio: 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, standby. First put it into the reactor, turn on the mixer of the reactor, add boscalid and epoxazole into the reactor under stirring, and stir until the reactant is completely dissolved; after the reactant is completely dissolved, add it to the reactor Add the remaining components to the mixture, and continue to stir for 15-60 minutes to obtain a uniform and transparent oily product, which is the present invention.

Embodiment 2

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

[0038] Each component was weighed according to the following proportions: 10kg boscalid, 3kg epoxiconazole, 5kg calcium alkylbenzenesulfonate, 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 mixer of the reactor, add boscalid and epoxiconazole into the reactor under stirring conditions, and stir until the reactant is completely dissolved; after the reactant is completely dissolved , and then add the remaining components into the reaction kettle, and continue to stir for 15-60min to obtain a uniform and transparent oily product, which is the present invention.

Embodiment 3

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

[0040] Each component was weighed according to the following proportions: 3kg boscalid, 5kg epoxiconazole, 5kg calcium alkylbenzenesulfonate, 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 mixer of the reactor, add boscalid and epoxiconazole into the reactor under stirring conditions, and stir until the reactant is completely dissolved; after the reactant is completely dissolved , and then add the remaining components into the reaction kettle, and continue to stir for 15-60min to obtain a uniform and transparent oily product, which is the present invention.

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, a preparation method and application thereof. Background technique [0002] The ultra-low-volume liquid preparation is a solvent with low volatility, high flash point, good solubility to the original drug, low phytotoxicity to crops, and low viscosity. It does not mix water when spraying, but uses an ultra-low-volume spray device , low-volume spray equipment or ultra-low volume electrostatic spray equipment for direct application. Ultra-low-capacity solvents, during the spraying process, since the droplets do not contain highly volatile components, the size and quality of the droplets do not change significantly when they leave the spray device and reach the target, so they can effectively reduce volatilization and drift. At the same time, the mist droplets are small and uniform, which meets the requirements of "bi...
