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

[0125] Example 1 EC

[0126] Milbemycin 0.5% imidacloprid 7.5% Cyclohexanone 20% Castor oil polyethylene glycol ether (35mol ethylene oxide) 5% Calcium dodecylbenzenesulfonate 3% xylene mixture Top up to 100%

[0127] 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

[0128] Example 2 wettable powder

[0129] Milbemycin 0.4% imidacloprid 8.4% sodium lauryl sulfate 2% Sodium lignosulfonate 10% Silica 10% Kaolin Top up to 100%

[0130] 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

[0131] Embodiment 3 water emulsion

[0132] Milbemycin 5% imidacloprid 45% N-Methylpyrrolidone 15% Sodium dodecyl benzene sulfonate 5% Phenylphenol polyoxyethylene ether 5% water Top up to 100%

[0133] 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 present invention relates to an insecticide composition, the active component is composed of (A) milbemycin and (B) at least one neonicotinoid compound, the active components (A) and (B) according to The weight ratio is 1:100‑100:1 by weight. Compared with the individual activity of each compound, the insecticidal composition of the present invention, the active components (A) and (B) are within the aforementioned proportioning range by weight, and the insecticidal composition of the present invention shows Clearly synergistic activity. The insecticidal composition is used for preventing or controlling harmful organisms. The present invention also provides a method for preventing or controlling pest infestation, comprising applying the pesticide of the present invention in any desired order or simultaneously on target useful plants or their environment, target harmful organisms or their environment, and propagating material of target useful plants. The active components (A) and (B) in the insect composition, the active component (B) is selected from imidacloprid.

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...
