Problems solved by technology

[0006] In the process of controlling pests with chemical pesticides, if long-term use of a single agent for control is likely to accelerate the resistance of pests, botanical pesticides are no exception. Currently, botanical insecticides that use matrine and Eupatorium bauhinia extracts as active ingredients The composition is used for controlling ornamental flower pests and indoor ornamental crop pests.

Embodiment 1

[0017] Example 1: Indoor Toxicity Determination of Eupatorium adenophorum Extract, Matrine and Different Proportions to Panonychus citrus

[0018] (1) Test medicament: Eupatorium adenophorum extract (using the reflux extraction method to extract Eupatorium adenophorum extract, its active ingredient is 98.1%); the original drug of matrine (Nantongshen, Jiangsu Province) with a mass percentage content of 5% Rain Green Pharmaceutical Co., Ltd.); the original drug was prepared into the required test agent according to the conventional method.

[0019] (2) Test method: The test refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The adult females of Panonychus citrus collected from the field were reared indoors for 30 generations, and the adult females with uniform growth were selected as the test insects. Adopt the small seedling method, that is, inoculate 50-60 heads of all claw mites on small pots of citrus seedlings, check the base numbe...

Embodiment 2

[0024] Example 2: 5.2% matrine · Eupatorium adenophorum extract solution of botanical pesticides

[0025] Add 5% Eupatorium adenophorum extract, 0.2% matrine, 2.5% sodium dodecylbenzenesulfonate, 1.5% polyvinylpyrrolidone, and deionized water to 100%, and mix them evenly at room temperature to prepare 5.2% matrine·Eupatorium adenophorum extract is a botanical pesticide solution.

[0026] This example is used to prevent and control Panonychus citrus in sugar orange orchards. The test site is Shuangqiao Town, Wuming County, Nanning, Guangxi. Conventional foliar spraying is used for uniform control, and the leaves are wet. There were more adult mites of Panonychus spp. in the field when the pesticide was applied. A total of 4 treatments were set up in the experiment, and each treatment was repeated 4 times. The insect population base in the field was investigated before spraying, and the insect situation was investigated 2 days, 5 days and 15 days after spraying, and the contro...

Embodiment 3

[0031] Example 3: 5.4% matrine · Eupatorium adenophorum extract solution of botanical pesticides

[0032] Add 5% Eupatorium adenophorum extract, 0.4% matrine, 3.5% sodium lauryl sulfate, 1.5% polyvinylpyrrolidone, deionized water to 100%, and mix well at room temperature to make 5.4% Matrine · Eupatorium adenophorum extract is a botanical pesticide solution.

[0033] This embodiment is applied to the prevention and treatment of the Milan red spider, an ornamental plant in the aisle of an office building. The red spider milan suffers serious damage, and the leaves appear grayish-yellow spots or plaques. Dilute the agent 500 times, and use a small hand-held sprayer for watering flowers to spray the affected plants. Two days after the application, the spider mites on the plants basically died, and the control effect reached more than 80%. There is no pungent smell of chemical pesticides in the place where the pesticide is applied, and it does not affect people's normal work and ...

Abstract

The invention relates to a botanical pesticide composition with matrine and eupatorium adenophorum spreng. The botanical pesticide composition comprises, by weight, 0.2-0.5% of extracted liquid of the matrine and 2-5% of extracted liquid of the eupatorium adenophorum spreng. A weight percent ratio of the extracted liquid of the matrine to the extracted liquid of the eupatorium adenophorum spreng is 2-5:20-50. The botanical pesticide composition has the advantages that the botanical pesticide composition is applicable to controlling agricultural common insect pests such as red spider mites, aphid and whiteflies with piercing sucking mouthparts for garden flowers, indoor ornamental plants, economic crops and vegetables; the botanical pesticide composition is low in toxicity for human and livestock and is low in usage and good in efficacy as compared with single dose, and obvious synergistic effects can be realized.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide synergistic composition, in particular to the preparation and application of a botanical pesticide composition containing matrine and Eupatoria adenophorum extract. Background technique [0002] At present, the control of diseases and insect pests is mainly based on chemical control. Chemical agents have the advantages of quick action and good efficacy. However, due to the high toxicity of chemical pesticides, irritating odor, and improper use, they will also cause phytotoxicity, so their use has certain limitations. Ornamental plants and flowers in public places and indoor offices are often threatened by spider mites, aphids and other pests. Spraying chemical pesticides will not only pollute the environment, but also greatly affect people's normal life and work. [0003] In view of the above technical problems, there is a need for a control agent with ...
