Problems solved by technology

The poor physical and chemical properties of the preparation can easily cause the loss of the liquid medicine, reduce the utilization rate of the pesticide, and then affect the efficacy of the medicine, and the lost pesticide directly causes serious pollution to the environment
At the same time, due to the poor efficacy of pesticides, in order to achieve a certain control effect, farmers will inevitably increase the amount and frequency of pesticide application, which will not only increase the cost of pesticide use, increase the resistance of pests and diseases, but also lead to serious excess of pesticide residues

Embodiment 1

[0062] Preparation Example 1: 1% emamectin benzoate microemulsion

[0063] The content of each component by weight is emamectin benzoate 1%, Silwet 408 5%, nonylphenol polyoxyethylene ether 3%, dimethyl sulfoxide 5%, BHT 2%, naphthyl propargyl ether 4%, Si1 8 0.2%, sodium hydroxide 0.2%, tap water to make up to 100%.

[0064] The emamectin benzoate is completely dissolved in dimethyl sulfoxide, and organic silicon surfactant and other additives are added, mixed evenly, then tap water is added, and a microemulsion preparation can be prepared after a little stirring.

Embodiment 2

[0065] Formulation example 2: 3% emamectin benzoate B 1a microemulsion

[0066] The content of each component is emamectin benzoate B by weight 1a 3%, Silwet 625 10%, nonylphenol polyoxyethylene ether 5%, dimethyl sulfoxide 10%, BHT 2%, naphthyl propargyl ether 4%, Si1 8 0.2%, sodium hydroxide 0.2%, tap water Top up to 100%.

Embodiment 3

[0067] Formulation Example 3: 2% emamectin emamectin saline emulsion

[0068] The content of each component is emamectin 2% by weight, Sylgard 309 5%, alkylphenol polyoxyethylene ether phosphate 3%, xylene 10%, butanol 2%, epoxy soybean oil 2%, naphthyl Propargyl ether 4%, Si1 8 0.2%, sodium hydroxide 0.2%, tap water to make up to 100%.

Abstract

The present invention relates to a liquid pesticide preparation which comprises the following components: 0.1wt%-10wt% of avermectin insecticide, preferably 0.5wt%-5wt%; 0.5wt%-25wt% of organosilicon surfactant, preferably 2wt%-10wt%; and water and / or organic solvent, wherein, the organosilicon surfactant is a framework which has a T type structure and is totally composed of methylated siloxane. The framework is suspended with trisiloxane ethoxylate of one or more than one polyether segment. The invention also provides a liquid pesticide preparation which comprises avermectin insecticide and organosilicon surfactant and a preparing method thereof.

Description

technical field [0001] The invention relates to a liquid pesticide preparation containing abamectin insecticides and organic silicon surfactants and a preparation method thereof. Background technique [0002] The use of pesticides to control diseases, insect pests and weeds is an indispensable means to ensure the high quality and high yield of agricultural products. To give full play to the efficacy of pesticides, it is necessary to ensure that the pesticide liquid is effectively spread, retained and deposited on the target. This requires formulations with excellent physical and chemical properties and low surface tension, with good wettability and permeability on the target surface. Poor physical and chemical properties of preparations are likely to cause the loss of liquid medicine, reduce the utilization rate of pesticides, and then affect the efficacy of pesticides, and the lost pesticides directly cause serious pollution to the environment. At the same time, due to th...
