Problems solved by technology

[0009] Another difficulty with the use of insecticides is that the repeated and exclusive use of a single insecticidal compound in many cases leads to rapid selection of pests that have developed natural or adapted resistance to the active ingredient.

Embodiment 1

[0127] Example 1 EC

[0128] Milbemycin

[0129] 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

[0130] Example 2 wettable powder

[0131] Milbemycin

[0132] 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

[0133] Embodiment 3 water emulsion

[0134] Milbemycin

[0135]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 (A) milbemycins and (B) at least one neonicotine compound. The weight ratio of the active component (A) to the active component (B) is 1:100-100:1. Compared with the activity of single components, the insecticidal composition has a prominently synergistic activity, when the weight ratio of the active component (A) to active component (B) 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, the active component (A) to active component (B) 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 insecticidal composition, the active component is composed of (A) milbemycin and (B) at least one neonicotinoid compound. The present invention also relates to the use of the pesticidal composition for preventing or controlling harmful organisms. The invention also provides a method of protecting seeds from soil insects and seedling roots and shoots from soil and foliar insects. Background technique [0002] In agricultural production, chemical agents are the most effective means of preventing and controlling plant diseases and insect pests. However, with the prolongation of the history of chemical control of agricultural pests and the influence of factors such as unscientific use of pesticides, in recent years, the resistance of agricultural pests has become increasingly serious, resulting in The types of resistant pests continue to increase, the degree of resistance is high, and the speed of resistance development is rela...
