Embodiment 1

[0018] Embodiment 1: the insecticidal composition is a suspending agent, and the percentages of each component are respectively:

[0019] Active ingredient (A +B) 5~80%,

[0020] Dispersant 5~20%,

[0021] Antifreeze 1~5%,

[0022] Thickener 0.1~2%,

[0023] Defoamer 0.1~2%,

[0024] pH adjuster 0.1~5%,

[0025] water balance.

[0026] 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 to 3 hours, so that the particle diameter is below 5mm, The suspension preparation of the insecticidal composition of the present invention can be obtained.

Embodiment 2

[0027] Embodiment 2: the insecticidal composition is an emulsion in water, and the percentages of each component are respectively:

[0028] Active ingredients (A+B) 5-80%,

[0029] Emulsifier 5~30%,

[0030] Solvent 5~15%,

[0031] Stabilizer 3~15%,

[0032] Antifreeze 2~5%,

[0033] Defoamer 0.2~5%,

[0034] Thickener 0.2~2%,

[0035] water balance.

[0036] The specific operation steps are as follows: firstly, the active ingredient A and the active ingredient B, a solvent and an emulsifier are mixed together, and dissolved to form a uniform oil phase. Then mix some 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 reactor, 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 insecticidal combination of the present invention water emulsion formulations. ...

Embodiment 3

[0037] Embodiment 3: the insecticidal composition is a microemulsion, and the percentages of each component are respectively:

[0038] Active ingredients (A+B) 5-80%,

[0039] Emulsifier 10-30%,

[0040] Antifreeze 2 ~ 10%,

[0041] Stabilizer 2~10%,

[0042] Solvent 20~50%,

[0043] water balance.

[0044] 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 auxiliary agents, mix well, finally add water, and after fully stirring, the insecticidal composition of the present invention can be obtained. Emulsion formulations.

Abstract

The invention discloses a mite-killing composition of etoxazole and hexiazox, the active ingredients of which are etoxazole and hexiazox, and the weight ratio of etoxazole and hexiazox is 20:1-1:20. The acaricidal composition of the present invention has an excellent control effect on harmful mites on fruit trees, cotton, vegetables and other crops, and has obvious synergistic effect; at the same time, it reduces the amount of pesticides used, reduces the pollution to the environment, and slows down the The development of pest mite resistance.

Description

technical field [0001] The invention relates to a pesticide acaricide composition and its application field, in particular to a binary compound compounded with etoxazole and hexythiazox as active ingredients, which is applied to the prevention and control of harmful mites on fruit trees, cotton and vegetables. Background technique [0002] Etoxazole, English common name: etoxazole, is a brand-new acaricide with a special structure. Its mode of action is to inhibit the embryogenesis of mite eggs and the moulting process from larvae to adult mites. It is effective for eggs and nymphs, but not for adult mites. Therefore, the best control time is the early stage of pest mite damage. The agent has strong rain resistance, a lasting period of up to 50 days, and is environmentally safe. It has excellent control effect on citrus, cotton, apple, flowers, vegetables and other crops such as Tetranychus, Tetranychus, Panonychus, Tetranychus urticae, and Tetranychus cinnabarinus. [00...
