Embodiment 1

[0014] Example 1: 20% Spirodiclofen Etoxazole Suspension Concentrate

[0015] Spirodifen 15kg

[0016] Etoxazole 5kg

[0017] Styrene phenol formaldehyde resin polyoxyethylene ether phosphate 6kg

[0018] Xanthan gum 0.3kg

[0019] Water to make up to 100kg

[0020] After the above-mentioned metering components are mixed, they are stirred by a primary sand mill, and after being sanded by a secondary sand mill, they are blended in a preparation kettle, and after the sampling inspection is qualified, the suspension preparation product is obtained by metering and subpackaging.

Embodiment 2

[0021] Example 2: 10% spirodiclofen etoxazole wettable powder

[0022] Spirodifen 6kg

[0023] Etoxazole 4kg

[0024] Pull open powder 3kg

[0025] Naphthalenesulfonate 2kg

[0026] Silica 5kg

[0027] Kaolin make up to 100kg

[0028] The above metered components are mixed and subjected to jet milling to obtain a wettable powder preparation product.

Embodiment 3

[0029] Example 3: 20% spirodiclofen·etoxazole emulsion in water

[0030] Spirodifen 15kg

[0031] Etoxazole 5kg

[0032] Block copolymer surfactant 10kg

[0033] Ethylene glycol 5kg

[0034] Water to make up to 100kg

[0035] After the above metered components are divided into two parts, the oil phase and the water phase, and mixed evenly, they are evenly stirred by a high-speed homogenizer to obtain a water-emulsion preparation product.

Abstract

The invention discloses an acaricide composition containing spirodiclofen and etoxazole and application thereof. Spirodiclofen and etoxazole are used as active components of the acaricide composition, and the mass ratio of spirodiclofen to etoxazole is 30:1 to 1:30. According to the invention, a mutual synergy effect of the two active components of the acaricide composition is obtained, and application of the acaricide composition not only enables control efficiency to be improved, but also enables problems of resistance, drug effects, cost and the like caused by utilization of a single component to be overcome, providing a novel acaricide composition for guiding control of pest mites.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an acaricide composition containing spirodiclofen and etoxazole and the application of the acaricide composition in preparing an acaricide for preventing and controlling crop pests. Background technique [0002] Agricultural pest mites are typical r countermeasure pests due to their small size, rapid reproduction and strong adaptability. They destroy the normal physiological functions of plants, cause leaf drop, bud drop, and fruit drop, which may cause yield reduction and weaken growth, and cause loss of harvest or death of the whole plant in severe cases. Many mites also spread plant diseases. At present, pest mites have gradually become important pests of fruit trees, vegetables, and agricultural and forestry crops, and almost all crops are harmed by pest mites (red spider mite, rust tick, tarsal line mite, etc.). And because acaricides have been relatively single and f...
