Embodiment 1

[0023] According to percentage by weight, cyclopyridam 10%, DMSO 10%, Pluronic F1085%, dodecanol-15% are added together to dissolve into a uniform oil phase. Mix 5% ethylene glycol, 2% 2-hydroxybiphenyl, 3% polyvinyl alcohol and water to form a uniform water phase. Under high-speed stirring, add the water phase to the oil phase to form a well-dispersed water emulsion.

Embodiment 2

[0025] Add 20% cyclopyridam, 20% xylene, 26% Pluronic L7, and 4% isobutanol by weight percentage to dissolve into a uniform oil phase. Mix 5% ethylene glycol, 2% p-hydroxybenzoate, 3% polyvinyl alcohol and water to form a uniform water phase. Under high-speed stirring, add the water phase to the oil phase to form a well-dispersed water emulsion.

Embodiment 3

[0027] Cyclopyrid field efficacy test:

[0028] With 20% cyclopyrid water emulsion of embodiment 2 with 45g.ai / hm 2 、60g.ai / hm 2 、90g.ai / hm 2 To prevent and control cotton aphids, investigate respectively 1 day after spraying, 3 days, 7 days, to the control effect of cotton aphids, the results of the investigation are compared with the contrast agent, the results are shown in Table 1, the results show that 20% epoxypyrid aqueous emulsion has a good effect on cotton Aphids have good control effects, and have good quick-acting and long-lasting effects, and are safe for cotton growth.

Abstract

The invention discloses a cycloxaprid emulsion in water and a preparation method thereof. Cycloxaprid is taken as an active ingredient of the cycloxaprid emulsion in water, and a solvent, an emulsifying agent or a dispersing agent, a co-emulsifying agent, water, an anti-freezing agent, a defoaming agent, an antimicrobial agent, a density regulator, a pH regulator, a thickening agent and a coloring agent are added. The technical, the solvent, the emulsifying agent and the co-emulsifying agent are mixed together and dissolved to form a uniform oil phase. The water, the anti-freezing agent, the antimicrobial agent and the like are mixed together for forming a uniform water phase. The water phase is added into the oil phase or the oil phase is added into the water phase under a high-speed stirring condition so as to form the emulsion in water with good dispersion. The invention provides an environmentally-friendly cycloxaprid preparation formulation which has the advantages of small dosage, long acting period, no environment pollution, no damage to natural enemies and the like and is safe for people and animals.

Description

technical field [0001] The invention relates to a cyclopyrid water emulsion and a preparation method thereof. Background technique [0002] Cyclopyrid is a new generation of ultra-high activity and ultra-low toxicity agricultural insecticide researched and developed by East China University of Science and Technology. Cyclopyrid is highly effective against Homoptera pests, and also has a concurrent control effect on Lepidoptera pests, especially against the major rice pest brown planthopper and the alien invasive pest Bemisia tabaci. In addition, it can also be used for cabbage aphids , Plutella xylostella, rice leaf roller and other pests. Cyclopyrid has a novel mechanism of action. Studies have shown that when the dosage of cyclopyrid is lower than 10 μM, it does not show agonist response to nicotinic acetylcholine receptors, but behaves as a pure antagonist, which is different from the current commercialized drug. The mechanism of action of the neonicotinoid receptor ago...
