[0017] Choose 10kg of fresh leaves or root bark of the Chinese herbal medicine vine, grind it into fine powder after drying and pass through a 100-mesh sieve, then add 0.2kg of lime powder, mix well in a mixer, and then it can become a powder biopesticide. The bio-pesticide contains 60% kaempferin, 5% saponin, 5% galthum, and the rest is fiber.

[0018] Application method: apply the powder biopesticide to the soil as a seed dressing or fertilizer.

[0019] Uses: Kill ground silkworms, grubs, soil dogs and other pests in the soil, with an effective rate of more than 90%.

Embodiment 2

[0020] Embodiment 2: Aqueous biopesticide

[0021] Select 10kg of fresh leaves or root bark of vine vine, squeeze out the original juice with a press or boil it in water, clarify for 24 hours, filter out the residue and concentrate, then add 0.5-0.8kg of lime juice, mix well, and it will become water dose of biological pesticides.

[0022] The composition of the bio-pesticide is: 65% kaempferin, 5% saponin, 5% galthum, and the rest is water.

[0023] Application method: Spray the water-based biopesticide sprayer directly on the leaves, roots, and stems of vegetables, rice, wheat, and fruit trees to kill pests such as soft bodies, fins, hard shells, and crawling.
