Abstract

A natural pyrethrin microemulsion as an insecticide for preventing and killing the most of agricultural and vegetable pests is prepared from natural pyrethrin, natural assistant, chemical assistant, and water.

Description

technical field [0001] The invention relates to an insecticide, in particular to a natural pyrethrin microemulsion insecticide and a preparation method. Background technique [0002] Natural pyrethrins have been used as insecticides for a long time, and can be used for the control of household hygiene pests and agricultural pests. Natural pyrethrin is an insecticide extracted from pyrethrum flowers. It is easy to decompose in light and air, and is highly toxic to agricultural harmful insects. It is safe to warm-blooded animals, has no pollution to the environment, and has no residue. In the prevention and control of agricultural pests, natural pyrethrins mostly appear in the formulations of powder, oil, wettable powder and emulsifiable concentrate. Moreover, pyrethrin oils and emulsifiable concentrates mostly use chemical organic solvents and plant-derived solvents, which not only pollute the environment, but also waste resources. The preparation of natural pyrethrin micro...
