Abstract
The invention discloses a plant source fruit tree insecticide. The plant source fruit tree insecticide comprises the following materials in parts by weight: 20-30 parts of bulbs of garlic, 20-30 parts of pyrethrums, 20-30 parts of red-knees herb, 5-10 parts of soap nuts, 10-15 parts of rotenone and 2-5 parts of levo alphla-terpilenol. A production method of the plant source fruit tree insecticide comprises the following steps of smashing the bulbs of garlic, the pyrethrums, the red-knees herb and the soap nuts; adding water 5-10 times the amount of the materials, boiling for 30 minutes-50 minutes, filtering, and adding water 3-5 times the amount of the filter residue into the filter residue for boiling for 20 minutes; and combining twice filtrates, adding the rotenone and the levo alphla-terpilenol for uniformly mixing to obtain a product. The product is taken and diluted by 300-500 times to spray, so that insects such as leaf roller moths, red spiders, aphids and tessaratoma papillosa drury can be effectively prevented.
