Embodiment 1

[0022] Example 1: 35% indoxacarb. Chlorpyrifos EW

[0023] 5.3 grams of 95% indoxacarb industrial product and 31.6 grams of 95% industrial product chlorpyrifos were dissolved in a mixed solvent containing 4 grams of N-dodecylpyrrolidone and 10 grams of Solvesso 150, and after the solution became transparent, 2 grams of JFC and 2 grams of JFC were added. Gram of EO / PO random copolymer is emulsified into dispersed phase, under high shear (5000-20000rpm), add to containing 3 grams of BY-140 (castor oil polyoxyethylene ether), 0.3 grams of silicone defoamer, 5 In the continuous phase of gram ethylene glycol, 0.05 gram sodium benzoate, 0.15 gram xanthan gum and 36.6 gram water, after adding, continue to shear 10 minutes and make 100 gram water emulsions. Gained water-emulsion viscosity is 210cP (with ROOKFIELD DV-+PROviscometer viscometer, No. 2 rotor, rotating speed 60 records, the same below), and particle diameter is detected by Malvern laser particle size distribution analyzer,...

Embodiment 2

[0026] Example 2: 25% indoxacarb.triazophos EW

[0027] Dissolve 5.3 grams of 95% indazole industrial product and 22.3 grams of 90% triazophos industrial product in a mixed solvent containing 5 grams of diethyl phthalate and 10 grams of Solvesso 200, and add 3 grams of penetrant after the solution is transparent TX, stirred into dispersed phase. Under high shear (5000-20000rpm), the dispersed phase was added to a mixture containing 2 grams of By-140 (castor oil polyoxyethylene ether), 3 grams of lauryl polyoxyethylene ether, 0.3 grams of silicone defoamer, 5 In the continuous phase of 1 gram ethylene glycol, 0.5 gram phosphoric acid, 2 gram polyvinyl alcohol and 41.6 gram water, continue to shear 10 minutes after adding and make 100 gram water emulsion. The obtained emulsion in water had a viscosity of 190 cP, and the particle diameters of the emulsion in water measured by a Malvern laser particle size distribution analyzer were D10 0.209 μm, D50 0.482 μm, and D90 0.873 μm. ...

Embodiment 3

[0030] Example 3: 30% indoxacarb.phoxim EW

[0031] Dissolve 15.8 grams of 95% indoxacarb industrial product and 16.9 grams of 89% phoxim industrial product in a mixed solvent containing 15 grams of N-octylpyrrolidone and 5 grams of Solvesso 200, and add 3 grams of isooctyl alcohol after the solution is transparent Polyoxyethylene ether, 2 grams of poly(12-hydroxystearic acid) polyoxyethylene block copolymer, re-emulsified into the dispersed phase. Under high shear (5000-20000rpm), the dispersed phase was added to a mixture containing 2 grams of tristyrylphenol polyoxyethylene ether phosphate, 3 grams of fatty alcohol EO / PO block copolymer, 0.3 grams of silicone defoamer, 5 In the continuous phase of 1 gram propylene glycol, 2 gram polyvinyl alcohol and 30 gram water, after adding, continue to shear 10 minutes and make 100 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 la...

Abstract

The invention discloses indoxacarb-containing aqueous emulsion and preparation method thereof. The aqueous emulsion contains: A) indoxacarb and B) chlorpyrifos, or triazophos or phoxim or chlorfenapyr or nitenpyram or buprofezin. By adding appropriate auxiliary agents of emulsifier, thickener, antifreeze and defoamer and allowance water and through certain processing technique, stable aqueous emulsion can be prepared. In the process of preparing the aqueous emulsion, non-pollution solvent is adopted, thus avoiding the bad influences from harmful solvent to the environment and to the health of the applier and the producer, and if used under the condition of the same dilution ratio, the aqueous emulsion has similar insecticidal effect to conventional missible oil. The aqueous emulsion has efficient broad spectrum insecticidal performance, can be used for comprehensive prevention and control and resistance control of pests and is suitable for use on green vegetable, fruit trees, crops and cotton.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to an emulsion in water of a pesticide composition containing indoxacarb and a preparation method thereof. Background technique [0002] Indoxacarb is a new oxadiazine insecticide developed by DuPont. It has contact and stomach poisoning effects. The mechanism of cross-resistance is to block the sodium ion channels in insect nerve cells, so that the nerve cells lose their function. Indoxacarb has low toxicity to mammals and livestock, and is very safe to beneficial insects such as non-target organisms in the environment. It is mainly used to control pests in vegetables, fruit trees, grain, cotton and other crops and gardening. The long-term use of a single agent often leads to the improvement of pest resistance, and the use of compound preparations can delay drug resistance, increase drug efficacy, expand insecticidal spectrum, and improve economic benefit...
