Abstract

The invention discloses a lycoris plant insecticide which is prepared from the following materials in parts by weight: 30-50 parts of artemisia vulgaris, 10-20 parts of azedarach, 20-50 parts of moringa seeds, 20-35 parts of gleditsia sinensis, 5-10 parts of garlic juice, 5-10 parts of pomegranate barks, 200-500 parts of lycoris, 20-50 parts of tea bran, 30-50 parts of tobacco leaves and 10-20 parts of rose willows. The insecticide disclosed by the invention takes lycoris as a primary component of the insecticide. The lycoris contains lycorine. Through high pressure extraction, the insecticidal effective components in the lycoris are effectively extracted and have a remarkable killing ability on injurious insects. The lycoris is matched with the raw materials such as the tea bran, the moringa seeds and the rose willows, so that the effect of the insecticide disclosed by the invention can be remarkably improved. The insecticide is wide in insecticidal range and free of toxic and harmful effects.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a lycoris plant insecticide and a preparation method thereof. Background technique [0002] Plant pesticides mainly refer to pesticides developed from secondary metabolites with agricultural biological activity produced by plants, animals, microorganisms, etc. Compared with traditional chemically synthesized pesticides, biologically derived natural product pesticides have the following characteristics: 1. Most biologically derived natural product pesticides are less toxic to mammals, and are relatively safe for humans and animals during use. 2. The prevention and control spectrum is narrow, and even has obvious selectivity. 3. It has less pressure on the environment and is safer for non-target organisms. And botanical insecticides are preparations for preventing and controlling crop pests made from plant secondary metabolites in biological natural product pesticides; botan...
