What is pyrethrum extract?
Pyrethrum extract is a kind of broad-spectrum pesticide that can control many kinds of pests, and its insecticidal toxicity is 10-100 times higher than the old generation pesticides such as organochlorine, organophosphorus and carbamate. Pyrethroids have a strong contact killing effect on insects, and some varieties have both stomach poisoning or fumigation effects, but none of them have systemic effects. Its mechanism of action is to disturb the normal physiology of nerve insects, causing them to die from excitement, spasm, and paralysis. Due to the small dosage and low concentration of pyrethroids, it is safer for humans and animals and has little pollution to the environment. The main disadvantage is that it is highly toxic to fish, and it is also harmful to some beneficial insects. long-term repeated use will also cause pests to develop drug resistance.
Pyrethrin is usually extracted at low temperature, and its processing technology is as follows: Dried flower granulation - subcritical biotechnology low temperature extraction - solvent recovery - pyrethrin products.
What is pyrethrum extract used for?
Botanical pesticide additives pyrethrum extract are excellent contact-killing botanical pesticides, ideal for manufacturing hygienic aerosols and hjagrifeed. pyrethrum extract is a kind of light yellow liquid extracted from the inflorescence of the dicotyledonous herb pyrethrumcinerariaefoliumTre.
the active ingredient is pyrethrin, which is one of the most effective natural insecticides with high efficiency and broad spectrum , the use of low concentration, has knockdown activity against pests, pests are not easy to produce resistance, low toxicity to warm-blooded animals and humans and animals, low residue and many other advantages, widely used in the field of sanitation and insecticide. pyrethrum is approved in the U.S. for use on certified organic farms.
Is pyrethrin toxic to dogs?
Pyrethrins & pyrethroids is toxic to dogs,pyrethrin is a yellow viscous liquid.

Botanical pesticide additives formulation support
As a preferred solution, the pesticide composition containing chrysanthemum wormwood and pyrethrum extracts is diluted with water to a concentration of 10-100 ppm of active ingredients based on the weight of the original medicinal materials, that is, the pesticide composition prepared after 1 g of the original medicinal materials is extracted. When it is diluted to 10kg with water, its active ingredient concentration is equal to 100ppm; it is further preferably diluted to an active ingredient concentration of 20-50ppm and sprayed on the leaf surface of the plant, so that a layer of water film appears on the leaf surface, and the liquid medicine does not drop. the second application is preferably carried out after 3 to 5 days, and the crop is preferably applied 2 to 3 times in a row.
The pesticide composition containing chrysanthemum wormwood and pyrethrum extract is composed of a mixture of chrysanthemum wormwood extract and pyrethrum extract, or a combination of chrysanthemum wormwood and pyrethrum extract, and its control effect is much higher than that of single-component extracts, especially After co-extracting chrysanthemum wormwood and pyrethrum, since chrysanthemum and pyrethrum have solubilizing and solubilizing effects, the pesticide composition prepared after co-extraction has a more significant insecticidal effect. compared with the prior art, hjagrifeed the pesticide composition containing chrysanthemum and
Pyrethrum Extracts Following Advantages as Natural Pesticide:
1. The pesticide composition containing chrysanthemum and pyrethrum extracts has a synergistic effect, and has an obvious control effect on lepidopteran pests.
2. Artemisia annua and pyrethrum are co-extracted or mixed separately after extraction, and the prepared pesticide composition can improve the ability of crop immune system and significantly improve its vitality while being quick-acting contact killing.
3. Using phytogenic feed additives as raw materials, there is no problem of pesticide residues, and it is difficult for pests to develop resistance; compared with the use of chemical source pesticides alone, it is environmentally friendly.
4. The pesticide composition containing chrysanthemum artemisiae and pyrethrum extract has low effective concentration and pyrethrum extract price when used.
Is Pyrethrum Extract Safe?
Yes, Pyrethrum extract is generally considered safe when used properly.
