Embodiment 1、10

[0031] Embodiment 1, 10% compound A aqueous suspension concentrate

[0032]

[0033] The preparation method is as follows: the above-mentioned substances are added to the mixing tank in turn and mixed, firstly subjected to high-shearing for coarse crushing and homogenization, and then pumped into the sand mill for fine grinding, and the particle size distribution meter detects the particle size of the sand-milled material. After the particle size reaches the standard requirement (≥98% through a 75 μm standard sieve), filter to obtain a 10% compound A aqueous suspension. The following formulation examples are all prepared in the same way.

[0034] The technical indicators of the sample in Example 1 are: pH value 6.3; suspension rate 93.8%; pourability: 3.5% residue after pouring, 0.2% residue after washing; persistent foaming (after 1min) 30mL; low temperature stability, Qualified; heat storage stability (54 ± 2) ℃ / 14 days, decomposition rate of 1.0%.

Embodiment 2、10

[0035] Embodiment 2, 10% compound A aqueous suspension

[0036]

[0037] The technical indicators of the sample in Example 2 are: pH value 6.5; suspension rate 96.5%; pourability: 3.8% residue after pouring, 0.2% residue after washing; persistent foaming (after 1min) 25mL; low temperature stability, Qualified; heat storage stability (54 ± 2) ℃ / 14 days, decomposition rate of 1.1%.

Embodiment 3、20

[0038] Embodiment 3, 20% compound A aqueous suspension

[0039]

[0040] The technical indicators of the sample in Example 3 are: pH value 6.6; suspension rate 95.9%; pourability: 3.9% residue after pouring, 0.3% residue after washing; persistent foaming (after 1min) 30mL; low temperature stability, Qualified; heat storage stability (54 ± 2) ℃ / 14 days, decomposition rate of 1.3%.

Abstract

The invention belongs to the field of agricultural acaricide and relates to a water suspending agent which takes a compound A as an acaricidal active ingredient, wherein a structural formula of the compound A is shown in the specification. The water suspending agent in the invention can be used as an acaricide for preventing and treating pest mites on agriculture, forestry or hygiene, has an excellent control effect on the pest mites such as tetranychus cinabarinus boisdu adults, nymphs and mite eggs, and is safe on crops.

Description

technical field [0001] The invention belongs to the field of acaricides, and relates to an acrylonitrile-based acaricide preparation, in particular to an acaricide preparation with compound 5 disclosed in CN101875633A as an active component and an application thereof. Background technique [0002] As we all know, acaricides have obvious effects in controlling agricultural and forestry pests or urban sanitation pests. However, after acaricides are used for a period of time, harmful mites will develop certain resistance. With people's increasing demand for pesticide products and increasing attention to environmental protection, there is an urgent need for low-cost, environmentally-friendly acaricides in agriculture. Variety of acaricides. Compound 5 (hereinafter referred to as compound A) disclosed in CN101875633A has excellent control effect on harmful mites such as Tetranychus cinnabarinus adult mites, nymphs and mite eggs, is safe for crops, is a highly efficient acaricide...
