Problems solved by technology

[0005] At present, the resistance of spider mite, spider mite, and two-spotted spider mite to pests of mites is gradually increasing, and the effect of a single dose of acaricide on the control of pest mites is gradually decreasing.
In addition, the price of hexythiazox is high, and the control cost is relatively high
The inventors have found through research that the synergistic compounding of pesticides is an effective measure to expand the control spectrum and improve the control effect, and at the same time reduce the cost of control. Up to now, there has been no acaricidal composition related to spirodiclofen and hexythiazox. application

Embodiment 1

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

[0015] Spirodifen 7kg

[0016] Hexythiazox 3kg

[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] Embodiment 2: 25% spirodiclofen·hexymethoxone aqueous emulsion

[0023] Spirodifen 21kg

[0024] Hexythiazox 4kg

[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·hexythiazox water-dispersible granules

[0030] Spirodifen 46kg

[0031] Hexythiazox 24kg

[0032] Naphthalenesulfonate 6kg

[0033] Ammonium sulfate 4kg

[0034] Kaolin make up to 100kg

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

Abstract

The invention discloses an acaricide composition containing spirodiclofen and hexythiazox and an application thereof. The composition treats spirodiclofen and hexythiazox as effective components, wherein the mass ratio of spirodiclofen to hexythiazox is 36:1-1:22. The synergistic acaricide composition containing spirodiclofen and hexythiazox of the invention can be applied to prepare acaricides for preventing crop pest mites, and especially to prepare acaricides for preventing pest mites on crops of cotton, orange, apple, or lemon and the like, and more especially to prepare acaricides for preventing pest mites of red spiders, carmine spider mites or twospotted spider mites and the like. The acaricide composition of the present invention allows problems of resistance, drug effects and cost brought by singly using one component to be solved.

Description

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