Clothianidin and beta-cyfluthrin suspending agent and preparation method thereof

Abstract

The invention relates to a clothianidin and beta-cyfluthrin suspending agent and a preparation method thereof. The suspending agent is prepared from the following raw materials in parts by weight: 20-25 parts of clothianidin, 5-10 parts of beta-cyfluthrin, 4-7 parts of a composite dispersing agent, 0.2-0.6 part of a nonionic lipid emulsifier, 0.3-0.7 part of an anionic sulfonate wetting agent, 3-5parts of an anti-freezing agent, 1-1.5 parts of a thickening agent, 0.1-0.3 part of a preservative, 0.5-1 part of a regulator and 0.1-0.5 part of a defoaming agent , with the balance being water. Thesuspending agent provided by the invention is prepared by adding the composite dispersing agent, the nonionic lipid emulsifier and the anionic sulfonate wetting agent into effective components; through a compounding effect of the composite dispersing agent, the nonionic lipid emulsifier and the anionic sulfonate wetting agent, the mixing uniformity of the components of the suspending agent can besignificantly improved; the wetting and dispersing effects of the suspending agent on the surface of the root part of garlic can be enhanced; thus, the pesticide effect of the suspending agent is exerted to a maximum extent when the suspending agent is used in a low-temperature environment; and by addition of the anti-freezing agent, the storage stability of a product can be easily kept when thesuspending agent is used in the low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a clothianidin and beta-cyfluthrin suspension and a preparation method thereof. Background technique [0002] During the growth of garlic, farmers often encounter pests and diseases such as garlic maggots. Garlic maggot larvae generally gather in underground parts such as garlic roots and bulbs, and mainly feed on garlic roots or cause incomplete garlic roots, or drill into garlic cloves to eat In severe cases, garlic maggots often drill through the epidermis, eat the heart tissue and gradually move up. The damaged parts are usually intact except for the boreholes. The aerial parts of the damaged garlic plants are short and the leaves turn yellow. In severe cases, the plant will die; therefore, the prevention and control of garlic maggots is urgent. If the prevention and control is not timely, the quality of garlic will decline, and loose petals and red-skinned garl...

Problems solved by technology

[0004] The above-mentioned insecticidal composition has good drug efficacy, but there are limitations in use: when the regional temperature is low, when the insecticidal composition compounded by clothianidin and cyromazine is sprayed on the roots of garlic, in a low-temperature environment, the insecticidal composition The insect composition is deposited on the root surface, and the drug effect cannot be maximized
