Abstract
An aquatic emulsion of natural pynethrin for preventing and eliminating the indoor pests (fly, mosquito, etc) and agricultural pests (aphis, locust, etc) contains proportionally natural pyrethrin, limonene, rosemary, tween, beta-cyclodextrin, non-ionic emulsifier and co-solvent. It has very low toxin and almost no by-effect.
Description
Technical field
The present invention relates to the insecticide technical field, specifically aqueous emulsion of natural pyrethrum and preparation method thereof.
Background technology
Existing natural pyrethrum insecticide variety is more, wherein the Dalmatian chrysanthemum aqueous emulsion since in its preparation process institute add beta cyclodextrin and have the microcapsules effect, the microcapsules people acts on the pyrethrin insecticidal action is slowed down, and is also referred to as the pyrethrin sustained release agent.This to insecticide brought as: strengthened the stability of pyrethrin, made advantages such as its range of application is wider.But in order to increase the insecticidal action of pyrethrin, added compound such as Butacide to improve its insecticidal activity in preparation, these compounds have certain harm to human and environment during machine, are limited the use of in developed country and area.
Summary of the invention
The purpose of this invention is to provide a kind of physicochemical property effectively improved greatly, strengthen aqueous emulsion of natural pyrethrum of stability and safety and preparation method thereof.
Technical scheme of the present invention is: aqueous emulsion of natural pyrethrum contains percentage by weight natural pyrethrum active ingredient 0.5～5%, synergist citrene class plant extracts 0.25～10%, repeatedly fragrant (plant extracts) 0.05～0.4% of stabilizing agent ether, Tween 80 0.25～2%, beta cyclodextrin 1～20%, nonionic emulsifier 10～30%, cosolvent 10%.
The preparation method carries out according to the following steps:
1) takes by weighing repeatedly perfume of pyrethrosin primary medicine, citrene class plant extracts, ether according to quantity, fully dissolve with cosolvent;
2) with beta cyclodextrin and emulsifier mixing, dissolve with cosolvent;
3) merge 1) and 2), fill up the water yield, with efficient mulser speed of agitator greater than 2000 rev/mins, pressure greater than the condition of 1.5 MPas under fully stirring, emulsification obtains aqueous emulsion of natural pyrethrum.
Pyrethrum element pesticide of the present invention is just to find the scope of application wideer through a large amount of screenings, synergist and stabilizing agent that insecticidal action further improves, both solved the shortcoming that the pyrethrin insecticide is seen photolysis, increased its insecticidal activity again, make it greatly reduce toxicity and side effect, strengthened the safety of using.In preparation process, adopt high-revolving efficient mulser processing, make the physicochemical property of product that bigger improvement be arranged, strengthened stability, make formulation products not stratified, improved the outward appearance of product simultaneously.
Its insecticidal constituent of aqueous emulsion of natural pyrethrum of the present invention, synergist and stabilizing agent all are natural plant product, and its toxicity is extremely low, almost have no side effect, and any country that can be worldwide uses and unrestricted.Its range of application is is also prevented and treated fly, mosquito, aphid from original being used to and is expanded the control that can be directly used in household control indoor pest and be used for agricultural pests (aphid, leech worm etc.) to, and this product has fungicide effect concurrently simultaneously.
