Embodiment 1
[0013] A biological source compound insecticide, the active ingredients include spinosyn and matrine. Weigh 0.2g of spinosad with effective content of 90% (provided by Hebei Sannong Chemical Co., Ltd.) and 1.8g of effective content of 5% matrine (provided by Henan Yale Biotechnology Co., Ltd.) and dissolve in 7ml A mother liquor of spinosad-matrine compound insecticide with a high concentration of 3% active ingredient was prepared in acetone solution. Wherein, the mass ratio of the active ingredients of spinosad and matrine is 2:1. When used in the field to control diamondback moth or strawberry thrips, the above mother liquor is diluted with 1000-6000 times of water to form an aqueous solution containing 5-30 mg / l of the active ingredient mixture of spinosad and matrine.

Weigh 0.1g of spinosad with effective content of 90% (provided by Hebei Sannong Chemical Co., Ltd.) and 3.6g of effective content of 5% matrine (provided by Henan Yale Biotechnology Co., Ltd.) and dissolve in 7ml A mother liquor of spinosad-matrine compound insecticide with a high concentration of 3% active ingredient was prepared in acetone solution. Wherein, the mass ratio of the active ingredients of spinosad and matrine is 1:2. When used in the field to control diamondback moth or strawberry thrips, the above mother liquor is diluted with 1000-6000 times of water to form an aqueous solution containing 5-30 mg / l of the active ingredient mixture of spinosad and matrine.
Embodiment 3
[0017] A biological source compound insecticide, the active ingredients include spinosyn and matrine. Weigh 0.27g of spinosad original drug with effective content of 90% (provided by Hebei Sannong Chemical Co., Ltd.) and 1.2g of original drug of matrine with effective content of 5% (provided by Henan Yale Biotechnology Co., Ltd.) and dissolve in 7ml A mother liquor of spinosad-matrine compound insecticide with a high concentration of 3% active ingredient was prepared in acetone solution. Wherein, the mass ratio of the active ingredients of spinosad and matrine is 4:1. When used in the field to control diamondback moth or strawberry thrips, the above mother liquor is diluted with 1000-6000 times of water to form an aqueous solution containing 5-30 mg / l of the active ingredient mixture of spinosad and matrine.
