Problems solved by technology

[0012] Another difficulty with the use of insecticides is that the repeated and exclusive use of a single insecticidal compound leads in many cases to the rapid selection of pests that have developed natural or adapted resistance to the active ingredient.

Embodiment 1

[0175] Example 1 EC

[0176] Milbemycin

[0177] The above components are mixed and stirred until a uniform transparent liquid is obtained to obtain the emulsifiable concentrate preparation of the present invention. Emulsions of any desired degree of dilution useful in plant protection can be obtained by diluting the abovementioned concentrates with water.

Embodiment 2

[0178] Example 2 wettable powder

[0179] Milbemycin

[0180] The active ingredient is thoroughly mixed with the auxiliary agent, and the mixture is fully ground in a suitable mill to obtain a wettable powder. It can be diluted with water to provide a suspension of the desired concentration.

Embodiment 3

[0181] Embodiment 3 water emulsion

[0182] Milbemycin

[0183] Add the active ingredients and additives together to dissolve into a uniform oil phase; mix the water-soluble components with water to prepare the water phase; mix the oil phase with the water phase under high-speed stirring to obtain the water emulsion of the present invention .

Abstract

The invention relates to an insecticidal composition. The active component of the insecticidal composition is composed of milbemycins and chlorpyrifos according to a weight ratio of 1:1-1:500. Compared with the activity of single components, the insecticidal composition has a prominently synergistic activity, when the weight ratio of milbemycins to chlorpyrifos is in the abovementioned range. The provided insecticidal composition is used to prevent and control pests, in particular, panonychus citri, tetranychus cinnabarinus, tetranychus urticae, psylla chinensis, bemisia tabaci, aphid, plutella xylostella, cnaphalocrocis medinalis, chilo suppressalis, and the like. The insecticidal composition is used to prevent or control external parasites of animals. The invention also provides a method of preventing or controlling the invasion of pests. According to the method, milbemycins and chlorpyrifos are sprayed on target useful plants or environment of target useful plants, target pests or environment of target pests, and target useful plant propagating materials in a random expected sequence or simultaneously.

Description

technical field [0001] The invention relates to an insecticide composition, the active component is composed of milbemycin and chlorpyrifos. The present invention also relates to the use of the pesticidal composition for preventing or controlling harmful organisms. Background technique [0002] Acarids, commonly known as spider mites, are pests of the class Arachnida. They are one of the important pests that damage fruit trees, cotton, Solanaceae, vegetables, ornamental flowers and other crops. Most of the common harmful mites belong to the orders Eucarina and Acarina. Mites mainly damage the leaves, stems and flowers of plants, and suck the stems and leaves of plants. In the early stage, there are a large number of pinpoint-sized chlorotic yellowish-brown spots on the front of the leaves. In the later stage, the leaves begin to chlorotic and shrink from bottom to top, and even fall off. Sometimes it starts from the leaves in the middle of the plant, and the leaves graduall...
