Abstract
The invention belongs to the technical field of pesticides and relates to an insecticide containing sophoridine and nicotine. The effective components of the insecticide include sophoridine and nicotine according to the weight ratio of 1:10-10:1, and further include auxiliary and fillers, wherein the sophoridine and the nicotine accounts for 0.2-10% of the total weight of the insecticide, and the auxiliary accounts for 5-30% of the total weight of the insecticide and the balance filler. Compared with a conventional insecticide, the composite insecticide containing sophoridine and azadirachtin has the advantages that compared with a single insecticide, the insecticide has evident synergy effect on the insects, and prevention effect can be improved obviously; the insecticide can substitute for a partial medium or high-toxic insecticides, usage of chemical agents is reduced, environmental pollution and residues on agricultural products are reduced; resistance of the insects to the single insecticide can be slowed down; and lasting period is long, and cost is reduced as compared with that of the single insecticide.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of insecticide that contains Sophoridine and nicotine of preventing and treating crop pests.
Background technology
Sophoridine mainly extracts molecular formula C from the white tattooing of Sophora Wild Leguminous Plant, sandliving sophora seed or sophora alopecuroide
15H
24N
2O, molecular weight 248.37, white crystalline powder, flavor are extremely bitter, generally use with medicine, as cancer therapy drug at present.Sophoridine passes through Toxicity Determination, pest is had tag and stomach poison function.Cabbage caterpillar on the crops such as fruit tree, vegetables, aphid, two spotted spider mite etc. there is obvious control efficiency.
Nicotine is commonly called as nicotine; be that tobacco is distinctive, belong to pyridine family alkaloid, for the manufacture of highly effective pesticide; to each class pest; tag, fumigation or stomach toxicity effect are all fine, because it is natural materials; its maximum characteristics are not have residual hazard; not causing secondary pollution, do not develop immunity to drugs, is the bioactive acid agrichemical of preserving the ecological environment.
Above-mentioned two kinds of materials are as the insecticide single dose, and it is at aspect Shortcomings such as pest controling effect, usage amount, cost accountings.
Summary of the invention
Technical problem to be solved by this invention provides a kind of crop pests that can be used in and prevents and treats, and the insecticide that contains Sophoridine and nicotine that effect is better, cost accounting is low.
The insecticides that contains Sophoridine and nicotine recompounding of the present invention, its active ingredient are Sophoridine and nicotine, and the Sophoridine that comprises in its composition and the weight ratio of nicotine are 1:10-10:1.Also include auxiliary agent and filler in its composition, wherein Sophoridine and nicotine account for the 0.2%-10% of insecticidal total weight, and auxiliary agent accounts for the 5%-30% of insecticidal total weight, and all the other are filler.
Insecticide of the present invention to the insect on fruit tree and the vegetable crop, such as cabbage caterpillar, aphid, two spotted spider mite etc., has significant control efficiency through actual test.
Composite insecticide of the present invention is compared with common insecticides, has the following advantages: 1, compare this kind with single dose insect is had obvious synergistic effect, can significantly improve control efficiency; 2, high malicious insecticide in can Substitute For Partial reduces the chemical agent usage amount, reduces the residual of environmental pollution and agricultural product; 3, can delay insect to the pesticide resistance of single insecticide, 4, have long advantage of lasting period, compare with single medicament, can reduce cost.
