Embodiment 1

[0038] Pests tested: tobacco budworm;

[0039] All test agents were provided by Yangling Fuji Biotechnology Co., Ltd.;

[0040] The results of the toxicity test are shown in Table 1:

[0041] Table 1: Toxicity determination results of toosendanin and cnidium seed oil compounded on tobacco budworm

[0042]

[0043]

[0044] It can be seen from Table 1 that the mixing ratio of toosendanin and cnidium seed oil is 3%-5%, 4%-10%, and the co-toxicity coefficient CTC>120 has synergistic effect, and the composition has synergistic effect on tobacco budworm effect.

[0045] The above-mentioned configuration of each dosage form is as follows:

[0046] 1. Environmentally friendly EC (EC): by mass percentage, toosendanin is 3% to 5%, cnidium seed oil is 4% to 10%, emulsifier is 5% to 10%, and synergist is 5% ~20%, organic solvents make up 100%. The raw materials are weighed according to the formula, added and mixed in sequence, and mixed and stirred evenly in a reaction kettle ...

Embodiment 2

[0060] Preparation of mixed medicine:

[0061] Preparation of 1.2% Toosendanin Cnidium Seed Oil Eco-Friendly Cream:

[0062] Get 12 parts of toosendanin·cnidium seed oil (the compounding ratio of toosendanin and cnidary seed oil is 5:7), add 12 parts of organic silicon, 4 parts of butyronyl ether and 3 parts of benzene on the basis of the above mixture Ethylphenol polyoxyethylene polyoxypropylene ether, 5 parts of ethyl acetate, ethanol to make up to 100 parts, and stir at a stirring speed of 800-1000 rpm for 10-30 minutes to prepare 1.2% toosendanin·cnidium Seed oil environmentally friendly emulsifiable concentrate.

[0063] Preparation of 1% toosendanin·cnidium seed oil microemulsion:

[0064] Take 10 parts of toosendanin·cnidium seed oil (the compounding ratio of toosendanin and cnidary seed oil is 4:6), add on the basis of the above mixture, 11 parts of organic silicon, 3 parts of ethylene glycol, 5 parts op-10, 15 parts of ethanol, water to make up to 100 parts, stirri...

Abstract

The invention discloses botanical insecticidal composition, a preparation and application of the botanical insecticidal composition or the preparation to control of crop pests. The composition at least contains toosendanin and fructus cnidii oil as active components, and the ratio of toosendanin to fructus cnidii oil in percentage by weight is (3-5):(4-10); when the preparation is prepared from the composition, the preparation can be in a form of environment-friendly emulsifiable concentrate, a microemulsion or a soluble liquid. The composition has a higher control effect on various pests in agricultural production and contains no chemical pesticide components, and drug resistance of the pests is not easily generated; the composition has the synergistic effect and is easily degradable in the environment and suitable for control of various organic crop pests, and the use quantity of pesticides is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a botanical pesticidal composition, a preparation and an application for controlling crop pests. Background technique [0002] Toosendanin is an effective insecticidal ingredient extracted from the root bark of the traditional Chinese medicine of the genus Melia spp. The Toosendan preparation has good antifeedant, endocrine poisoning, stomach poisoning and certain growth inhibitory effects, and is safe, effective in prevention and control, and friendly to the environment. [0003] Cnidium seed oil is extracted from the dried fruit Cnidium chinensis of the Umbelliferae plant Cnidium. It is used in medicine and health products, beverage and food additives, etc., and contains osthole. A botanical insecticide with osthole as an active ingredient, used to control stored grain beetles, book lice, and corn weevils, and also has high activity against cabbage caterpillars. [0004] Sim...
