Example Embodiment
[0009] Example 1: 5.5% Sophoridine·Nicotine Water Dispersible Granules
[0010] 0.5g sophoridine, 5g nicotine, 4g sodium lauryl sulfate, 2g laureth, 2g lignosulfonate, 2g sulfonic acid polyoxymethylene condensate (NNO), 2g polyethylene glycol, 4 g of ammonium sulfate, 10 g of sodium carboxymethyl cellulose, and kaolin were supplemented to 100 g to prepare 5.5% sophoridine·nicotine water dispersible granules.
Example Embodiment
[0011] Example 2: 5.5% Sophoridine·Nicotine Water Dispersible Granules
[0012] 5g sophoridine, 0.5g nicotine, 4g sodium lauryl sulfate, 2g lauryl alcohol polyoxyethylene ether, 2g lignosulfonate, 2g sulfonic acid polyoxymethylene condensate (NNO), 2g polyethylene glycol, 4 g of ammonium sulfate, 10 g of sodium carboxymethyl cellulose, and kaolin were supplemented to 100 g to prepare 5.5% sophoridine·nicotine water dispersible granules.
[0013] According to the formulations of Examples 1 and 2, the active ingredients, additives, and fillers were mixed, stirred evenly, and then pulverized to obtain a master powder. The master powder and the binder were mixed uniformly, and then granulated, dried, and sieved. Sophoridine·nicotine water dispersible granules can be prepared.

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 [0001] The invention belongs to the technical field of pesticides, and relates to an insecticide containing sophoridine and nicotine for preventing and controlling crop pests. Background technique [0002] Sophoridine is mainly extracted from Sophora genus wild leguminous plants, white thorn flower, sandy locust tree or bitter bean seed, molecular formula C 15 h 24 N 2 O, molecular weight 248.37, white crystalline powder, extremely bitter taste, currently widely used in medicine as an anticancer drug. Sophoridine has been tested for indoor toxicity and has contact and stomach toxicity to agricultural pests. It has obvious control effect on cabbage caterpillar, aphid, spider mite, etc. on fruit trees, vegetables and other crops. [0003] Nicotine, commonly known as nicotine, is unique to tobacco and belongs to the pyridine family of alkaloids. It is used to make high-efficiency pesticides. It has good effects on various pests, contact killing, fumigation o...
