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.

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.
