Embodiment 1

[0022] Example 1: 2.5% spinosad · abamectin EW

[0023] Dissolve 0.63 g of 80% spinosad industrial product and 2.2 g of 92% avermectin industrial product in a mixed solvent containing 5 g of N-dodecylpyrrolidone and 10 g of Solvesso 150, and add 1 g of it after the solution is transparent UV-N1, 2 grams of JFC, 2 grams of EO / PO random copolymer are emulsified into a dispersed phase, and under high shear (5000-20000rpm), add 3 grams of Nongru 602*, 0.3 grams of silicone defoamer , 5 gram ethylene glycol, 0.05 gram sodium benzoate, 0.5 gram phosphoric acid, 0.3 gram xanthan gum and the continuous phase of 68.02 gram water, after adding, continue to shear 10 minutes and make 100 gram water emulsion. Gained water-emulsion viscosity is 230cP (with ROOKFIELD DV-+PRO viscometer, No. 2 rotor, rotating speed 60 record, the same below), record the particle diameter of water-emulsion with Malvern laser particle size distribution instrument to be D10 0.305 μ m, D50 0.554 μm, D900.930 μm....

Embodiment 2

[0026] Example 2: 5% spinosad emamectin benzoate EW

[0027] Dissolve 3.8 grams of 80% spinosad industrial products and 3 grams of 68% emamectin benzoate in a mixed solvent containing 10 grams of diethyl phthalate and 15 grams of Solvesso 200 until the solution is transparent Then add 1 gram of UV-R1, 3 grams of penetrant TX, and 2.5 grams of poly(12-hydroxystearic acid) polyoxyethylene block copolymer, and then emulsify into a dispersed phase. Under high shear (5000-20000rpm), the dispersed phase was added to a mixture containing 3 grams of By-140 (castor oil polyoxyethylene ether), 0.3 grams of isooctyl alcohol defoamer, 5 grams of glycerin, 0.05 grams of benzoiso In the continuous phase of thiazolinone, 0.5 gram of citric acid, 0.3 gram of gelatin and 52.55 gram of water, continue shearing for 10 minutes after adding to prepare 100 gram of water emulsion. The obtained emulsion in water had a viscosity of 250 cP, and the particle diameters of the emulsion in water measured by...

Embodiment 3

[0030] Example 3: 12% Spinosyn · Lambda-Cyhalothrin EW

[0031] Dissolve 7.5 grams of 80% spinosad industrial products and 31.5 grams of 95% lambda-cyhalothrin industrial products in a mixed solvent containing 6 grams of N-octylpyrrolidone and 93 grams of Solvesso 200, and add 3 grams after the solution is transparent Antioxidant (BHT), 9 grams of isooctyl polyoxyethylene ether, and then emulsified into a dispersed phase. Under high shear (5000-20000rpm), the dispersed phase was added to a mixture containing 9 grams of dodecyl EO / PO block copolymer, 6 grams of tristyrylphenol polyoxyethylene ether phosphate, 0.9 grams of isooctyl alcohol, 15 In the continuous phase of 9 gram propylene glycol, 9 gram polyvinyl alcohol and 110.1 gram water, continue to shear 10 minutes after adding and make 300 gram water emulsion. The obtained emulsion in water has a viscosity of 158 cP, and the particle diameters of the emulsion in water measured by a Malvern laser particle size distribution ...

Abstract

The invention discloses a water emulsion containing pleocidin and a preparation method thereof. The water emulsion comprises the following components: A) the pleocidin; and B) abamectin, methylamino-abamectin benzoate, efficient bifenthrin, lufenuron, efficient cypermethrin, chlorfenapyr, chlorfluazuron, diafenthiuron, thiamethoxam or fipronil. The stable water emulsion is prepared by adding a proper amount of auxiliary agents such as an emulsifying agent, a thickening agent, an antifreezing agent, a UV-protecting agent, a defoaming agent and the like and the balance of water through a certain processing technique. A nuisanceless solvent is used for preparing the water emulsion to avoid adverse effects on the environment, a user and the health of a producer caused by a harmful solvent. The water emulsion has board-spectrum and efficient insecticidal properties, can be applied to the comprehensive control and resistance control on pests, and is suitable to be used on nuisanceless vegetables, fruit trees, grains and cotton.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to an aqueous emulsion of a pesticide composition containing spinosad and a preparation method thereof. Background technique [0002] Spinosad is a macrolide biopesticide, which has rapid contact and stomach poisoning effects on pests, but has no systemic effect, and has a strong penetration effect on leaves, which can kill pests under the epidermis. It is long and has a certain ovicidal effect on some pests. It can effectively control Lepidoptera, Diptera and Thysanoptera pests, and it can also prevent certain pests that eat a lot of leaves in Coleoptera and Orthoptera. , but less effective against piercing-sucking pests and mites. Spinosad is relatively safe to predatory natural enemy insects, and has no cross-resistance with commonly used insecticides. The composition containing spinosyn, that is, its compound preparation, expands the insecticidal spec...
