Embodiment 1

[0035] Dinotefuran 6%, monosultap 9%, diethylene glycol distearate 4%, dodecyl dihydroxyethyl betaine 12%, ethyl acetate 15%, n-butanol 8%, sub Triphenyl Phosphate 2%, Propylene Glycol 5%, Water Make Up 100%.

[0036] Mix the solvent, co-solvent and emulsifier evenly, add dinotefuran, and stir at a speed of 100 rpm for 30 minutes to obtain an oil phase. In addition, add monosultap, stabilizer, and antifreeze into water, and stir at a speed of 100 rpm for 20 minutes to obtain a water phase. Then, drop the water phase into the oil phase while stirring at a speed of 200 rpm, and continue to stir at the same speed for 60 minutes to obtain the microemulsion of the present invention.

Embodiment 2

[0038] Dinotefuran 5%, monosultap 12%, diethylene glycol distearate 5%, dodecyl dihydroxyethyl betaine 10%, dichloromethane 13%, n-butanol 7%, di Sodium Hexyl Succinate Sulfonate 1%, Glycerol 4%, Water Make Up 100%.

[0039] The preparation method is the same as in Example 1.

Embodiment 3

[0041] Dinotefuran 7%, monosultap 8%, diethylene glycol distearate 4%, dodecyl dihydroxyethyl betaine 10%, ethyl acetate 14%, isopropanol 9%, butyl Glycidyl ether 3%, sorbitol 6%, water make up 100%.

[0042] The preparation method is the same as in Example 1.

Abstract

The invention relates to a pesticide containing dinotefuran and ethiofencarb. The pesticide is prepared into microemulsion. The formula comprises dinotefuran, ethiofencarb, an emulsifier, a solvent, a cosolvent, a stabilizer, an anti-freezing agent and water, and has excellent stability. The invention also relates to application of the pesticide in the aspect of controlling agricultural insects.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a pesticide microemulsion containing dinotefuran and monosultap, its preparation method and application. Background technique [0002] Dinotefuran is a neonicotinoid insecticide, soluble in methanol, ethanol, isopropanol, ethyl acetate, acetonitrile, dichloromethane, insoluble in cyclohexane, xylene and other organic solvents. Dinotefuran has contact and stomach poisoning effects, and can be used in various crops such as wheat, rice, cotton, and vegetables to effectively control agricultural pests such as Lepidoptera and Homoptera. Dinotefuran will undergo hydrolysis in water-based formulations, which will affect its efficacy. [0003] Insultap is an artificially synthesized nereistoxin analogue. It is white to light yellow powdery solid at room temperature and is easily soluble in water and ethanol. Monosultap is a competitive inhibitor of acetylcholine, which can be quickly transfo...
