Embodiment 1

[0020] Example 1: 35% Buprofezin·Spirofen-Spirofen Suspension Concentrate.

[0021] 30% Buprofezin, 5% Spirodiclofen, 15% Alkylphenol Formaldehyde Resin Polyethylene Sulfonate, 15% Sodium Lauryl Sulfonate, 2% Xanthan Gum, 2% Glycerin, 0.1% Silicone Oil , deionized water make up 100%. Mix the above active ingredients, dispersant, wetting agent, thickener, antifreeze, defoamer and deionized water, disperse with high speed shearing, and sand mill in a sand mill to form a highly dispersed and stable 35% buprofezin spirodiclofen suspension concentrate can be prepared.

Embodiment 2

[0022] Example 2: 40% buprofezin·spirofen-emulsion in water.

[0023] Buprofezin 30%, spirodiclofen 10%, xylene 10%, cyclohexanone 5%, fatty acid polyoxyethylene ether 10%, polycarboxylate 10%, sodium sorbate 1%, glycerol 1%, Deionized water makes up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase, dissolve the antifreeze in water to form a water phase, slowly add the oil phase to the water phase under the action of a shearing machine, and continue to shear for about In 30 minutes, a 40% buprofezin-spirofen-in-water emulsion can be prepared.

Embodiment 3

[0024] Example 3: 35% Buprofezin·Spirofen Microemulsion.

[0025] 15% buprofezin, 20% spirodiclofen, 20% cyclohexanone, 15% styrylphenol polyoxyethylene ether, 2% sodium citrate, 1% organic silicon, 2% doublyl, deionized water to make up 100% %. Dissolve the active ingredients completely in a solvent, then add emulsifier, stabilizer, penetrant, and synergist to mix evenly, and finally add deionized water, and stir well to obtain 35% buprofezin spirodiclofen Microemulsion.

Abstract

The invention discloses an insecticidal and acaricidal composition containing buprofezin and spirodiclofen. The composition contains buprofezin and spirodiclofen which serve as active ingredients, wherein a ratio of buprofezin to spirodiclofen is equal to (1:40) to (40:1) in parts by mass. In practical application, the composition can be prepared into such application dosage forms as a suspending agent, an emulsion in water, a microemulsion, water dispersible granules, wettable powder, ultra-low volume liquor, a microcapsule suspending agent and hot fogging concentrate, and the total weight of buprofezin and spirodiclofen accounts for 1%-85% of the weight of the composition. The insecticidal and acaricidal composition disclosed by the invention has a synergistic effect, widens a prevention and control spectrum and can be used for preventing and controlling various agricultural pests such as red spiders, leafhopper, aleyrodid, phylloxera and scale insects.

Description

technical field [0001] The pesticide composition involved in the present invention uses buprofezin and spirodiclofen as active ingredients and is used for preventing and controlling agricultural pests. Background technique [0002] Buprofezin is a chitin synthesis inhibitor of heterocyclic insects. Its mechanism of action is to destroy the formation of new epidermis of insects, interfere with the normal growth and development of insects, and cause the death of insects. It has special effects on homopteran pests such as planthoppers, leafhoppers, whiteflies and scale insects. [0003] Spirodiclofen is a spirocyclic tetronic acid acaricide, the mechanism of action is to inhibit the fat synthesis of mites, block the energy metabolism of mites, and cause the death of mites. It can be used to prevent and control harmful mites on fruit trees, eggplant, pepper, tomato and other Solanaceous crops. In addition, it also has a good control effect on pests such as pear psyllid, elm oy...
