Problems solved by technology

However, a single chemical pesticide has problems such as pesticide residues that endanger the environment and are prone to resistance
Plant pesticides have the advantages of environmental protection, low toxicity, and not easy to produce biological resistance. However, plant pesticides are slow in drug resistance and easy to decompose active ingredients.

Abstract

The present invention discloses a method for preparing a compond insecticide. The method comprises the steps of: at the room temperature, separately weighing tobacco rhizome extract and xiaochongthion in a mass ratio of (0.2-5): 1 and adding the two into weighing bottles, and preparing a mixture of tobacco rhizome extract and xiaochongthion; then adding ethanol to 80-200 mL to prepare a mixed solution system of the tobacco rhizome extract and xiaochongthion, wherein the content of the mixture is (3-7.2) g / 100mL in the mixed solution system; and sufficiently stirring the mixed solution system and leaving the system to stand to obtain the product. The method for preparing the compound insecticide has the advantages that by compounding the plant pesticide tobacco rhizome extract extract which is green, low in toxicity and hard to generate biological resistance with a conventional chemical pesticide xiaochongthion which is strong in insecticidal capacity and by using synergistic effect of both, purposes that the compound insecticide is low in toxicity and environmental-friendly, strong in insecticidal capability, low in decomposition rate of active components and hard to generate biological resistance are achieved.

Description

technical field [0001] The invention relates to the research on the new technology of "green pesticide", in particular to a preparation method of compound insecticide. Background technique [0002] Chemical pesticides have the title of "pest killer" in agriculture and forestry, and are widely used in the prevention and control of modern agricultural and forestry pests, benefiting human beings. However, a single chemical pesticide has problems such as pesticide residues that endanger the environment and are prone to resistance. Plant pesticides have the advantages of environmental protection, low toxicity, and not easy to produce biological resistance. However, plant pesticides have slow drug properties and easy to decompose active ingredients. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a preparation method of a compound insecticide with low toxicity, environmental protection, strong insecticidal ability, low deco...
