Problems solved by technology

[0004] Acarids are a kind of common pests, which harm vegetables, fruit trees, cotton and other crops, and often cause devastating disasters to crops. There are many generations of harmful mites and strong reproductive ability. Rapid multiplied growth in a short period of time, so it is easy to develop resistance to acaricides, and at the same time cause serious damage to crops

Embodiment 1

[0020] Embodiment 1: the acaricidal composition is a suspension concentrate, and the percentages of each component are respectively:

[0021]

[0022] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredient A and active ingredient B, grind in a ball mill for 2-3 hours, so that the particle diameter is below 5mm, The suspension formulation of the acaricidal composition of the present invention can be obtained.

Embodiment 2

[0023] Embodiment 2: the acaricidal composition is an emulsion in water, and the percentages of each component are respectively:

[0024]

[0025]

[0026] The specific operation steps are: first mix active ingredient A and active ingredient B, solvent, and emulsifier together to dissolve into a uniform oil phase; then mix part of water and other additives together to dissolve into a uniform water phase; then Add the oil phase to the water phase while stirring at high speed in the reaction kettle, slowly add water until reaching the phase inversion point, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain the acaricidal composition of the present invention Emulsion formulations in water.

Embodiment 3

[0027] Embodiment 3: the acaricidal composition is a microemulsion, and the percentages of each component are respectively:

[0028]

[0029] The specific operation steps are: completely dissolve the active ingredient A and the active ingredient B with a solvent and a co-solvent, then add other auxiliaries, mix well, finally add water, and after fully stirring, the acaricidal composition of the present invention can be obtained. Emulsion formulations.

Abstract

The invention discloses a mite-killing composition which regards the etoxazole and the vermectin as effective components. The mass fraction ratio of the etoxazole to the vermectin is (10:1)-(1:10),preferably (5: 1)-(1: 5); the total percentage by weight of the etoxazole and the vermectin is 4%-85% by weight of the composition. When practical application is carried out, the mite-killing composition containing etoxazole and vermectin is prepared into application dosage forms including a suspending agent, an aqueous emulsion, a micro-emulsion, wettable powder, water dispersible granule and missible oil; the accumulated percentage by weight of the effective components in the preparation is 4%-85%. The mite-killing composition containing etoxazole and vermectin is used for preventing and treating various pest mites on crops, such as panonychus ulmi, etranychus urticae koch, tetranychus cinnabarinus and rust mites.

Description

technical field [0001] The invention relates to a pesticide acaricidal composition and its application field, in particular to an acaricidal composition containing etoxazole and ivermectin. Background technique [0002] Etoxazole belongs to diphenyloxazoline acaricides, has strong contact effect, can inhibit the normal molting process of mites, has strong activity on eggs, larvae, and nymphs, and has an inhibitory effect on female adult mites. [0003] The mechanism of action of ivermectin is mainly to bind with high affinity to the chloride ion channel with glutamate as the valve in the nerve cells and muscle cells of invertebrates, which leads to the increase of the permeability of the cell membrane to chloride ions, causing nerve cells or muscle cells to Hyperpolarizes, paralyzing or killing pests. It is now commonly used in medicine to prevent and control intestinal parasites in mammals, and in agriculture, it can be used to control agricultural pests such as vegetable ...
