Problems solved by technology

Thrips pests have a wide range of hosts and can harm melons, fruits, vegetables, etc. Thrips adults and nymphs feed on heart leaves, buds, flower organs and young fruit juice with file-sucking mouthparts, and young leaves and shoots are damaged, causing growth and development. Obstructed, reduced yield and reduced quality, especially on strawberries, causing great harm to strawberry seedlings and fruit picking
For the control of the above pests, people have begun to use some biological source insecticides to replace chemical broad-spectrum insecticides, such as using nicotine, veratrine, azadirachtin, Bacillus thuringiensis, etc. to control fruit trees, vegetables and other crops, although in the short term It has a certain effect, but the effect is not significant enough, and a certain degree of drug resistance has also been produced after long-term use

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.

Embodiment 2

[0015] A biological source compound insecticide, the active ingredients include spinosyn 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.

Abstract

The invention discloses a biological source compound insecticide and application thereof, belonging to the field of compound insecticides. The major active ingredients of the compound insecticide include spinosyns and sophocarpidine; and each liter of insecticide diluted in filed contains 5-20mg of the mixture of the compounded active ingredients of spinosyns and sophocarpidine. The invention also discloses application of the compound insecticide in preventing and controlling plutella xylostella and thrips. In the invention, by compounding two known pesticides in a certain manner, a synergistic efficient insecticide is obtained, and an obvious synergistic effect is shown in the simulation test and field test; and in the invention, the spinosyns and sophocarpidine are biological source preparations which bring little pollution to the environment and products and can be automatically degraded so as to avoid the enrichment.

Description

technical field [0001] The invention relates to a biological source insecticide, in particular to a biological source compound insecticide against thrips and diamondback moth and application thereof. Background technique [0002] For a long time, in order to ensure the output and quality of agricultural products, people have used a large amount of chemical pesticides in production, which has caused great pressure on the ecological environment, causing some pests to quickly develop resistance to pesticides, increasing the difficulty of field control, and causing pesticide residues in agricultural products The amount seriously exceeds the standard, causing great harm to humans, animals and the environment. The development and utilization of environmentally compatible and harmless pesticide resources are increasingly favored by various countries. [0003] Plutella xylostella is one of the important pests that damage cruciferous vegetables, causing great damage to vegetables. ...
