Problems solved by technology

The insecticides in the prior art can only be effectively used when the scale insects shed their shells or when the larvae leave the mother body, and are limited by the growing season of the scale insects, so they cannot be used at any time
Moreover, there are generally problems of short drug efficacy and high frequency of application, resulting in large dosage and high cost

Embodiment Construction

[0017] The invention provides a composition for controlling scale insects, which is a combined suspending agent of fenoxycarb (2(4-phenoxyphenoxy)ethylcarbamate), comprising: fenoxycarb at 1.25%- 2.5% by weight, 4% by weight of solvent, 6% by weight of dispersant, 4%-5% by weight of 50% by weight of penetrant, the penetrant is preferably penetrant T, and the rest is water.

[0018] Wherein, the chemical name of penetrant T is sodium di-sec-octyl maleate sulfonate. The penetrant T has high penetrating power, and the penetrating property is rapid and uniform. When the penetrant T is used in the composition for preventing and controlling scale insects of the present invention, the efficacy of the medicine can be significantly increased, and the effect is remarkable.

[0019] Preferably, the above solvent of the present invention can be one or more of alcohols, ketones, esters and aromatic hydrocarbons, accounting for 4% by weight of the composition.

[0020] Preferably, the abov...

Abstract

The invention provides a composition and method for preventing and treating scale insects. The composition for preventing and treating the scale insects is fenoxycarb combination floating agents and comprises, by weight, 1.25 percent to 2.5 percent of fenoxycarb, four percent of solvents, six percent of dispersing agents, four percent to five percent of penetrating agents of 50 percent and the balanced water. The method for preventing and treating the scale insects is further provided. According to the technical scheme, the composition and method have at least one of the advantages that the pesticide effect is lasting, and cost is saved; the broad spectrum, high efficiency and low toxicity are achieved, the scale insects can be effectively killed, meanwhile, other budworms and aphids can be killed, and the composition and method are environmentally friendly and safe for human beings and animals; the composition is not limited by seasons and the growing period of the scale insects, and can be applied at any time, and the scale insects can be effectively killed.

Description

technical field [0001] The invention relates to a composition and its application method, in particular to a composition for controlling scale insects and its application method. Background technique [0002] Currently, various compositions have been developed to control pests to reduce losses caused by pests. But for scale insects, because of the wax layer on their bodies, there is currently no pesticide that can achieve the desired control effect. Scale insects are the main pests of plants such as orchards, tea gardens, forest trees and flowers, which can easily cause fallen leaves, flowers and fruits, etc., affecting the yield and quality of plants. The insecticides in the prior art can only be effectively used when the scale insects shed their shells or when the larvae leave the mother body, and are limited by the growing season of the scale insects and cannot be used at any time. Moreover, there are generally problems of short drug effect and high frequency of applica...
