Pyrethrum Extract Powder

Product Description

Natural pyrethrum extract, also known as pyrethrin, is the main insecticidal component in pyrethrum flowers. In recent years, the stability of pyrethrum, especially the research on light stability, has been greatly developed, which greatly promotes the use of pyrethrin in agricultural pest control. applications in . Since the production and use of synthetic pesticides cause great pollution to the natural environment, while pyrethrins are obtained by planting, the extraction process and use of these pesticides cause little environmental pollution. Dr. Steele of the United States has conducted in-depth research on pyrethrum and believes that pyrethrin is the safest and most effective natural insecticide in the world.

Application

Application of pesticide composition containing chrysanthemum and pyrethrum extracts

The pesticide composition containing Artemisia annua and Pyrethrum extracts of the present invention has good control effect on lepidopteran pests such as cabbage caterpillars, diamondback moth, Spodoptera litura and the like.
