Abstract
The invention belongs to the technical field of pesticides and relates to an insecticide containing sophoridine and azadirachtin for preventing insects of crops. The effective components of the insecticide include sophoridine and azadirachtin according to the weight ratio of 1:10-10:1. 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 ingle 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 nimbin 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.
Nimbin is the vegetable insecticide that extracts the chinaberry from seal, have food refusal, avoid keep away, interior suction and the inhibition effect of growing.Main Function reduces the burst size of moulting hormone in the endocrine system of insect; Also can directly destroy epidermal structure or stop the chitinous formation of epidermis, or disturb respiratory metabolism, affect Development of Reproductive System etc.Safer to environment, people and animals, natural enemy, insect is difficult for developing immunity to drugs.
Above-mentioned two kinds of materials are as 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 to the crop pests control efficiency insecticide that contains Sophoridine and nimbin preferably.
The insecticides that contains Sophoridine and azadirachtin complex of the present invention is characterized in that: its active ingredient is Sophoridine and nimbin, and the Sophoridine that comprises in its composition and the weight ratio of nimbin are 1:10-10:1.Also include auxiliary agent and filler in its composition, wherein Sophoridine and nimbin 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.
