Embodiment 1

[0024] Embodiment 1: Pseudostellariae Pseudostellariae is directly used in the control of stored pests

[0025] (1) Place fresh dried Radix Pseudostellariae Radix Pseudostellariae in 10g per packaging bag at the bottom and opening of the grain bag (rice or wheat flour); the control group places an empty packaging bag;

[0026] (2) Place a bag of rice where the rice weevil pest has occurred, or wheat flour where the rice borer pest has occurred, and then stack 30 bags of the grain with Radix Pseudostellaria and the control grain without Radix Radix Pseudostellaria within a diameter of 1 meter;

[0027] (3) Regularly observe and count the number of stored pests in grain bags, and evaluate the effect of pest control. As shown in Table 1, no obvious storage pests were found in the rice and wheat flour grain bags containing Pseudostellariae Radix Pseudostellariae within 2 years, indicating that Pseudostellariae Pseudostellariae has a good control effect on storage pests.

Embodiment 2

[0030] Embodiment 2: Using Pseudostellariae Grinding Powder for the Control of Storage Pests

[0031] (1) Grind fresh dried Radix Pseudostellariae into powder, put 10g in each package bag, and place it at the bottom and opening of the grain bag (rice or wheat flour); place the empty package bag in the control group;

[0032] (2) Place a bag of rice with rice weevil pests or wheat flour with rice borer pests, and then stack 30 bags of the grain containing Pseudostellariae and the control grain without Pseudostellariae powder within a diameter of 1 meter ;

[0033] (3) Regularly observe and count the number of stored pests in grain bags, and evaluate the effect of pest control. As shown in Table 2, the rice and wheat flour grain bags placed with Pseudostellariae powder did not find a large number of storage pests within 2 years, indicating that Pseudostellariae powder has a good control effect on storage pests.

Embodiment 3

[0036] Embodiment 3: Using Pseudostellaria superfine powder for the control of stored pests

[0037] (1) dry Radix Pseudostellariae powder is made superfine powder;

[0038] (2) Add 0.1% superfine powder of Radix Pseudostellariae to the grain, mix and place; add equal amount of talcum powder to the control group;

[0039] (3) Place a bag of rice with rice weevil pests or wheat flour with rice borer pests, and then add 30 bags of grain with superfine powder of heterophylla and control grain without superfine powder of heterophylla in 1 Stacked within the diameter of one meter;

[0040] (4) Regularly observe and count the number of stored pests in grain bags, and evaluate the effect of pest control. As shown in Table 3, the grain bags of rice and wheat flour added with Pseudostellaria superfine powder did not find a large number of storage pests breeding within 2 years, indicating that Pseudostellaria superfine powder has a good control effect on storage pests.

Abstract

The invention discloses application of radix pseudostellariae and a radix pseudostellariae total saponin extract in prevention and control of stored insect pests, and relates to the technical field of application of radix pseudostellariae. According to the application of the radix pseudostellariae, the radix pseudostellariae is used for preventing and treating stored insect pests. The radix pseudostellariae and the total saponin extract of the radix pseudostellariae are used as stored insect prevention and control substances, so that the long-acting, economic and safe excellent characteristics are achieved, the problem of pesticide residues of existing stored insect prevention and control drugs is solved, and the good application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of Pseudostellariae application technology, in particular to the application of Pseudostellariae Pseudostellariae and total saponins extract of Pseudostellariae Pseudostellariae in the prevention and control of stored pests. Background technique [0002] Food is the foundation of people's food and clothing, the foundation of national economic development, and the foundation of social stability. my country is a large agricultural country, but also a large grain storage country. The annual grain output and perennial storage volume both rank first in the world. [0003] According to statistics, storage pests are an important cause of grain loss, causing an annual loss of more than 5%, which directly threatens the safety of my country's grain reserves. Moreover, in the control of storage pests, pesticides and insecticides are often used, which increases the risk of pesticide residues in grain and food safety. ...
