[0040] 1. Examples of preparation and biological activity of the composition

[0041] 1. Preparation of EC

[0042] According to the requirements of the formula, add the solvent, the original drug, and the emulsifier separately, mix them evenly, and heat to dissolve in a water bath if necessary to obtain a transparent cream.

Embodiment 1

[0043] Example 1. Emulsifiable concentrate with 30% total weight concentration of effective active ingredients

[0044] The total mass concentration of the two active ingredients is 30% emulsifiable concentrate, in weight percentage, composed of the following components: compound A 15%, compound B 15%, agricultural milk 0203B 6%, agricultural milk 0201B 9%, cyclohexanone The ketone is 8%, and the balance is No. 150 mineral spirits.

Embodiment 2

[0045] Example 2. Emulsifiable concentrate with 30% total weight concentration of effective active ingredients

[0046] The sum of the mass concentration of the two active ingredients is 30% emulsifiable concentrate, in terms of weight percentage, composed of the following components: compound A 20%, compound B 10%, Nongru 2201#6%, Nongru 0201B 8%, ring Hexanone 8%, the balance is 150# solvent oil.

[0047] 2. Preparation of wettable powder

[0048] According to the requirements of the formula, the original medicine, various additives and fillers are fully mixed, and then pulverized by the ultrafine grinder to obtain the processed product.

Abstract

The invention discloses an acaricidal pesticide composition and applications thereof, wherein the acaricidal pesticide composition contains two active ingredients, the first active ingredient is a compound A, the second active ingredient is a compound B, the molecular structural formula of the compound A is represented by a formula (A), and the molecular structural formula of the compound B is represented by a formula (B). According to the present invention, the two active ingredients show an extremely strong synergistic effect, the composition formed by mixing the two active ingredients has the obviously-improved acaricidal effect compared with one of the active ingredient, can kill eggs, young mites, weak mites and adult mites, and has long lasting period.

Description

Technical field [0001] The invention relates to an insecticide, in particular to an acaricide pesticide composition and its application. Background technique [0002] Agricultural pest mites are small in size, fast in reproduction, strong in adaptability, and easy to produce resistance. They are one of the most difficult pests to control. Pest mites are important organisms in fruit trees, vegetables, and agricultural and forestry crops. They mainly damage leaves, but also young shoots, flower buds and fruits. After the number of insects increases sharply, plants often fall leaves, inhibit their growth and even die. The crops in the affected areas tend to be slightly shorter, and their quality and yield are significantly reduced. [0003] Long-term use of a single acaricide species is likely to cause rapid development of resistance. Therefore, the development of a new acaricide composition is of great significance for delaying the service life of acaricides and slowing down the de...
