Embodiment 1

[0031] The preparation of the botanical insecticidal additive of the present invention comprises the following steps:

[0032] (1) Weigh the plant raw materials according to the following parts by weight: 4 parts of castor, 10 parts of Tripterygium wilfordii, 7 parts of deer vine root, 2 parts of sophora flavescens, 6 parts of toosendan, 4 parts of ageratum, 1 part of pepper powder, 5 parts of citrus peels were pulverized, passed through a 50-mesh sieve, and mixed evenly to obtain a plant raw material mixture;

[0033] (2) Add water 10 times the total weight of the plant raw material mixture, decoct at 70°C for 4.5 hours, filter to remove the filter residue, and obtain a water extract;

[0034] (3) Concentrate the water extract under reduced pressure into a paste, dry, pulverize, pass through an 80-mesh sieve, and mix well to obtain the product.

Embodiment 2

[0036] The preparation of the botanical insecticidal additive of the present invention comprises the following steps:

[0037] (1) Weigh the plant raw materials according to the following parts by weight: 10 parts of castor, 7 parts of Tripterygium wilfordii, 4 parts of deer vine root, 4 parts of sophora flavescens, 2 parts of toosendan, 6 parts of ageratum, 5 parts of pepper powder, 1 part of citrus peel, crushed, sieved through a 40-mesh sieve, and mixed evenly to obtain a plant raw material mixture;

[0038] (2) Add water 12 times the total weight of the plant raw material mixture, decoct at 80°C for 3 hours, filter to remove the filter residue, and obtain a water extract;

[0039] (3) Concentrate the water extract under reduced pressure into a paste, dry, pulverize, pass through a 100-mesh sieve, and mix well to obtain the product.

Embodiment 3

[0041] The preparation of the botanical insecticidal additive of the present invention comprises the following steps:

[0042] (1) Weigh the plant raw materials according to the following parts by weight: 7 parts of castor, 7 parts of Tripterygium wilfordii, 7 parts of deer vine root, 4 parts of sophora flavescens, 4 parts of toosendan, 4 parts of ageratum, 2 parts of pepper powder, 6 parts of citrus peels were pulverized, passed through a 60-mesh sieve, and mixed evenly to obtain a plant raw material mixture;

[0043](2) Add medicinal ethanol that is 8 times the total weight of the plant raw material mixture, extract for 4 hours, filter to remove the filter residue, and obtain an alcohol extract;

[0044] (3) Concentrate the alcohol extract under reduced pressure into a paste, dry, pulverize, pass through an 80-mesh sieve, and mix well to obtain the product.

Abstract

The invention discloses plant source insecticidal additives capable of preventing and controlling underground harmful insects. The plant source insecticidal additives are prepared from ricinus communis, tripterygium glycosides, derris roots, sophora flavescens, melia toosendan, ageratum conyzoides, paprika powder and orange peel by conducting concentrating, drying, smashing, screening and even mixing on an extracting solution prepared through water extracting, alcohol extracting and ultrasonic extracting processes. The plant source insecticidal additives are prepared by extracting effective components from plants with insecticide and sterilization functions and can effectively prevent and control harms of crop underground harmful insects, and meanwhile it is avoided that when chemical prevention and treatment insecticide phoxim, chlorpyrifos and the like are used for preventing and controlling underground harmful insects, soil hardening, soil loss, soil depletion and other problems are caused; in the use process, the additives are mixed with and used in cooperation with fertilizer, fertilizer and insecticide dual functions are achieved, labor, time and money can be saved, and labor intensity and the number of labor times of farmers are decreased; the additives are wide in raw material source, low in price, simple in preparation process and low in preparation cost and has wide application and popularization prospects.

Description

technical field [0001] The invention belongs to the technical field of crop disease and insect pest control, and in particular relates to a botanical insecticidal additive capable of preventing and controlling underground pests. When used, it is mixed into fertilizers and applied together. Background technique [0002] Sugar cane, peanuts, corn, sweet potatoes and vegetables are the main crop varieties in the south, especially in Guangxi, and they are the source of income increase for farmers. However, due to the constraints of the land, the crop rotation is difficult, the continuous cropping is inevitable, and under the condition of high soil temperature and humidity, it is easy to breed underground pests. In recent years, the planting of vegetables, corn, and potatoes has been increasingly harmed by underground pests. Seriously, the white radish "flower skin" cannot be sold, and the "black heart" of sweet potatoes has halved the output. These are all caused by the damage o...
