Embodiment 1

[0031] Add 20% of Methochlor, 30% of Terbutylazine, 15% of D-Limonene, and 20% of Starch Sodium Octenyl Phosphate into a 50mL flat-bottomed glass bottle in turn, add a magnet, and stir and mix at a speed of 1500rpm for 15min; Take 3% ethylene glycol, 5% xanthan gum, 0.5% methyl polysiloxane, make up to 100% with deionized water, and mix it in another 50mL flat-bottomed glass bottle at a speed of 1500rpm for 15min; at room temperature, Under the condition of stirring at a rotating speed of 2000 rpm, the water phase was added to the oil phase, and stirred and mixed for 30 minutes to form a nano-water emulsion with a mass percentage of methoxam and terbuthylazine of 50%.

Embodiment 2

[0033] Add 50% of methoxam, 10% of terbutyzine, 10% of biodiesel, and 10% of isooctyl polyoxyethylene ether into a 50mL flat-bottomed glass bottle in turn, add magnets, stir and mix at 2000rpm for 10min; take urea 8 %, 1% hydroxypropyl cellulose, 0.3% isooctyl alcohol, deionized water to make up to 100%, in another 50mL flat-bottom glass bottle, stir and mix at 2000rpm for 10min; at room temperature, stir at 1500rpm Under certain conditions, the water phase was added to the oil phase, and stirred and mixed for 40 minutes to form a nano-water emulsion with a mass percentage of methoxam and terbuthylazine of 60%.

Embodiment 3

[0035] Add 1% of methoxam, 9% of terbutyzine, 5% of N-dodecylpyrrolidone, and 2% of polyoxyethylene stearate into a 50mL flat-bottomed glass bottle in turn, add a magnet, and stir and mix at a speed of 1000rpm 15min; Take 1% sorbitol, 1% gum arabic, make up to 100% with deionized water, put in another 50mL flat-bottomed glass bottle, stir and mix at 1000rpm for 15min; The water phase was added to the oil phase, and stirred and mixed for 30 minutes to form a nanoemulsion in water with 10% by mass of methoxam and terbuthylazine.

Abstract

The invention discloses pesticide nano emulsion in water and a preparing method thereof. Pethoxamid and terbuthylazine are used as effective components of the pesticide nano emulsion in water, environment-friendly pesticide solvent and emulgator are adopted, an appropriate amount of auxiliaries such as an antifreeze agent, a thickening agent and an antifoaming agent and the balance water are added, and the stable emulsion in water is prepared through a low-energy emulsion method. According to the pesticide nano emulsion in water, high dynamical stability is used, nano emulsion is introduced into application of pesticide emulsion in water, and the prepared pesticide nano emulsion in water is high in stability, beneficial for plant absorption, environmentally friendly compared with a traditional missible oil product, simple in preparing process, low in cost, high in controllability and convenient to produce and process, causes little environment load and has a good weeding effect on broadleaf weeds and grassy weeds of a soybean field.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a pesticide water emulsion and a preparation method thereof, in particular to a pesticide nano water emulsion containing methoxam and terbuthylazine and a preparation method thereof. Background technique [0002] In recent years, with the increasing environmental protection pressure faced by the world, the national environmental protection department has formulated stricter regulations on the safety and environmental protection of pesticides, forcing people to develop safe and environmentally friendly new pesticide formulations, in which water emulsion replaces flammable and flammable Explosive and toxic oil-based preparation emulsifiable concentrates are becoming the development direction of pesticide preparations in the world. Pesticide water emulsion is a kind of green water-based preparation that is dispersed in water as tiny droplets by means of hydrophobic liquid pesticide or solid ...
