High-efficiency agricultural tackifying synergist

Abstract

The invention discloses an agricultural high-efficiency tackifying synergist and a preparation method of the agricultural high-efficiency tackifying synergist, and belongs to the technical field of pesticide auxiliaries. According to the weight percentage, the agricultural high-efficiency tackifying synergist is formed by the mixed reaction of 10%-40% of triethanolamine, 50%-80% of isooctanol polyoxyethylene isooctyl ether phosphate and 1%-10% of isocyanate. The novel high-efficiency tackifying synergist is high in affinity to the surface of a plant, so that the water solubility of products can be enhanced, and the emulsion stability of products can be improved. The residence time of medicine liquid on the surface of the plant can be effectively prolonged, the medicament absorption and the liquid level permeation can be promoted, conglutination and diffusion of medicament on a target difficult to wet can be enhanced, the dissolution of the medicament can be accelerated, the droplet drift can be reduced, a wax coat on the plant epidermis can be dissolved, the loss of the medicine liquid can be effectively reduced, the absorption of the target crop to a pesticide can be preferably carried out, and the direct interaction effect of the pesticide can be improved.

Description

technical field [0001] The invention relates to a novel high-efficiency viscosity-increasing synergist for pesticides and a preparation method thereof, belonging to the technical field of pesticide adjuvants. Background technique [0002] At present, the role of chemical products in agriculture is already indispensable, such as pesticides, fertilizers, plant growth regulators and so on. The application of chemical products in agriculture has guaranteed the increase of production and efficiency, but at the same time it has brought a lot of environmental problems and caused some harm to the human body, such as the volatilization of VOC and the residue of pesticides. Therefore, how to make good use of chemical products, reduce pollution and damage under the premise of ensuring efficiency, and realize environmental protection and sustainable development is a problem that must be solved. [0003] In agrochemical products, the use of pesticides accounts for a considerable proport...

Problems solved by technology

At present, there are many kinds of agricultural synergists, such as the commercially available 1.8% viscosifying abamectin emulsifiable concentrate, which can improve the adhesion and residence time of the liquid medicine on the surface of the substrate to a certain extent, but Because it uses a small molecule surfactant with a certain viscosity as a thickening emulsifier, the product does not increase the viscosity of the liquid obviously

For example, the commercially available agricultural silicone can effectively reduce the surface tension of the liquid medicine and the contact angle between the liquid medicine and the surface of the substrate, and is an excellent tank-mixed agricultural synergist, but because the agricultural silicone is heptamethyltrisiloxane polyoxygen Vinyl ether compound, this substance is easy to cause rearrangement in acid and alkali or water, resulting in failure. If it is added to emulsifiable concentrate, the emulsifying performance needs to be readjusted. Experiments have proved that after one year of storage, the effect is reduced by more than 50%, and the emulsifying performance is unqualified
