Embodiment 1

[0014] Example 1: 10% spirodiclofen·bromodiclofen wettable powder

[0015] Spirodifen 8kg

[0016] Bromofen 2kg

[0017] Pull open powder 3kg

[0018] Naphthalenesulfonate 2kg

[0019] Silica 5kg

[0020] Kaolin make up to 100kg

[0021] The above metered components are mixed and subjected to jet milling to obtain a wettable powder preparation product.

Embodiment 2

[0022] Example 2: 25% spirodiclofen·bromodiclofen emulsion in water

[0023] Spirodifen 20kg

[0024] Bromofen 5kg

[0025] Block copolymer surfactant 10kg

[0026] Ethylene glycol 5kg

[0027] Water to make up to 100kg

[0028] 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.

Embodiment 3

[0029] Example 3: 70% spirodiclofen·bromodiclofen water dispersible granules

[0030] Spirodifen 46kg

[0031] Bromofen 24kg

[0032] Naphthalenesulfonate 6kg

[0033] Ammonium sulfate 4kg

[0034] Kaolin make up to 100kg

[0035] After dissolving the active ingredients, adding the wetting and dispersing agent naphthalene sulfonate, stirring evenly, adding kaolin, mixing, grinding and granulating, and drying to obtain a water-dispersible granule preparation product.

Abstract

The invention discloses an acaricide composition containing spirodiclofen and bromopropylate, and application thereof. The composition comprises effective components of spirodiclofen and bromopropylate in a mass ratio of 25:1-1:19. Two active components in the acaricide composition of the present invention have mutual synergism, can increase control effect during application, and can also solve problems of resistance, drug effect and costs caused by single usage of a certain component. Therefore, the invention provides a brand new acaricide composition for guiding pest mites control.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an acaricide composition containing spirodiclofen and bromofen 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, fast 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 few...
