Pesticide water surface oil spreading film agent and preparation method thereof

Abstract

The invention discloses a solid water surface oil spreading film agent for preventing disease and injurious pests of roots of paddy rice and weeds in a paddy rice field and a preparation method thereof. The preparation form of the pesticide water surface oil spreading film agent comprises pesticide active compounds, solvent, oil absorption carrier, film forming agent and film spreading additive and can be processed into tablet or granule product, when in use, the tablet or granule products can be directly thrown into the paddy rice field with water, the preparation falling into the water of the paddy rice field is not settled but floated on the water surface, the tablets or granules can be rapidly decomposed and dissolved in the water, the absorbed solvent and pesticide active components can be rapidly released and automatically dispersed to the periphery, an oil film is formed on the water surface of the paddy rice field and spread to the entire water surface of the paddy rice field, the oil film can automatically climb along the paddy rice stems and can be absorbed by the paddy rice roots, so that diseases and injurious pests such as rice planthopper, Chilo suppressalis and rice sheath blight disease harmful to the roots of the paddy rice stem can be prevented, and the weeds in the paddy rice field also can be controlled. The preparation is a novel pesticide preparation, the application method is greatly simplified, the working efficiency for applying pesticide to the paddy rice field can be improved, the labor intensity for controlling the diseases, injurious pests and weeds in the paddy rice field can be alleviated, and the hard labor for protecting the paddy rice can be avoided.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide formulation suitable for use on paddy fields and a preparation method thereof. Background technique [0002] The use of pesticides to control the occurrence and damage of diseases, insect pests and weeds is an important means to ensure high and stable yields in the rice production process. There are many types and formulations of pesticides currently used, but their application in the field is mainly by spraying with water. The method is limited by many aspects such as production scale, spraying technology and spraying equipment, the operation efficiency is not high, time-consuming and labor-intensive, and pesticide spraying is easy to produce floating pollution. Especially in the context of my country's current aging population and declining rural labor population, the use of pesticides has become a technical bottleneck restricting my country's rice pr...
