Chromafenozide suspending agent suitable for aircraft spraying operation and preparation method of chromafenozide suspending agent

Abstract

The invention discloses a chromafenozide suspending agent suitable for airplane spraying operation and a preparation method of the chromafenozide suspending agent. The suspending agent is prepared from 3-8% of chromafenozide, 1-2% of sodium alginate, 0.5-1% of mussel mucopolysaccharide, 0.1-0.3% of citric acid, 0.8-1% of ethyoxyl modified trisiloxane, 0.8-1.2% of a dispersing agent, 0.4-0.6% of an emulsifying agent and the balance of water. According to the invention, the chromafenozide suspending agent prepared by the invention has good surface tension and emulsification dispersibility, can be flatly laid on the surfaces of leaves, is large in coverage range, can be better adhered to the leaves, and has slow-release and long-acting insecticidal effects, and the liquid medicine forms a uniform medicine film on the surfaces and the leaves of plants, so that the volatilization of the medicine effect is reduced, and the the chromafenozide suspending agent is especially suitable for killing hyphantria cunea in a larva stage during flying prevention operation.

Description

technical field [0001] The invention relates to the field of forestry and agricultural pest protection, in particular to a cyclofenozide suspending agent suitable for aircraft spraying operations and a preparation method thereof. Background technique [0002] The American white moth, belonging to the order Lepidoptera, Slightidae, and the genus White moth, has another name called American light moth, autumn curtain caterpillar, autumn curtain moth, and is a worldwide quarantine pest. It mainly harms fruit trees, street trees and ornamental trees, especially broad-leaved trees. The American white moth has strong reproductive ability and rapid spread, and can spread 30-50 kilometers outward every year. The large-scale reproduction and spread of the American white moth brought various bad signs to the trees, and even caused the death of the entire forest. At the same time, it also threatened the environment and seriously affected the ecological balance. In North China, there ...

Problems solved by technology

[0006] Aiming at the problems in the prior art that the method of killing white moth by aircraft spraying has short duration of drug effect, fast volatilization of drug effect, many times of spraying and low insecticidal efficiency to white moth larvae, the present invention provides a A cyclofenozide suspending agent suitable for aircraft spraying operations. The cyclofenozide suspending agent prepared by this patent has good surface tension and good emulsification and dispersibility, and can be spread on the surface of the blade with a large coverage and better adhesion Connected to the leaves, it has the effect of slow release and long-term insecticide, and at the same time, the liquid medicine forms a uniform film on the plant surface and leaf surface, reducing the volatilization of the medicine effect
