Embodiment 1

[0123] Example 1 Emulsifiable concentrate

[0124] Milbemycin

[0125] The above components are mixed and stirred to a uniform and transparent liquid to obtain the emulsifiable concentrate preparation of the present invention. By diluting the above-mentioned concentrate with water, an emulsion of any desired degree of dilution that can be used for plant protection can be obtained.

Embodiment 2

[0126] Example 2 Wettable powder

[0127] Milbemycin

[0128] The active ingredient is fully 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

[0129] Example 3 Water emulsion

[0130] Milbemycin

[0131] Add the active ingredients and additives together to dissolve into a uniform oil phase; mix the water-soluble components and water to prepare the water phase; under high-speed stirring, mix the oil phase and the water phase to prepare 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 spirodiclofen diester according to a weight ratio of 1:100-100:1. Compared with the activity of single components, the insecticidal composition has a prominently synergistic activity, when the weight ratio of milbemycins to spirodiclofen diester 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 invention also provides a method of preventing or controlling the invasion of pests. According to the method, milbemycins and spirodiclofen diester 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. The invention also provides a method of preventing seeds, seedling roots, and branches from the invasion of pests in soil and on leaf surfaces.

Description

Technical field [0001] The invention relates to an insecticide composition, the active component is composed of milbemycin and spirodiclofen. The present invention also relates to the use of the insecticidal composition for preventing or controlling harmful organisms; the present invention also provides a method for protecting seeds, seedling roots and branches from soil and foliar insects. Background technique [0002] Mites, commonly known as red spiders, belong to the class of arachnids. They are one of the important pests that damage fruit trees, cotton, Solanaceae, vegetables and ornamental flowers. The common harmful mites mostly belong to the order Acarina and Acarina. Mites mainly damage the leaves, stems and flowers of plants. They pierce and suck the stems and leaves of plants. In the early stage, there are a lot of small yellowish-brown dots with the size of needle-tips on the front of the leaves. In the later stage, the leaves begin to chlorosis and shrink from bottom...
