Embodiment 1

[0074] The surfactant in this embodiment is rhamnolipid biosurfactant, the emulsifier is alkyl polyoxyethylene ether, and the antifreezing agent is ethanol. The specific component names and mass distribution are shown in Table 1:

[0075] Table 1

[0076]

[0077] Concrete preparation method is:

[0078] (1) Preparation of refined wood vinegar: oak wood is carried out dry distillation, and the gas derived during dry distillation is condensed to obtain the wood vinegar stock solution; after the wood vinegar stock solution is allowed to stand for 6 months and the tar is precipitated, get the clarified upper strata wood vinegar solution; The upper layer of wood vinegar is distilled under reduced pressure at a temperature of 90° C. and a pressure of 0.12 MPa until the volume of the distillate is 80% of the original volume to obtain refined wood vinegar.

[0079] (2) Preparation of botanical fungicide:

Embodiment 2

[0085] The method for preparing the botanical fungicide in this example is roughly the same as that in Example 1, except that the surfactant in this example is polyoxyethylene hydrogenated castor oil 40, the emulsifier is polyoxyethylene fatty acid ester, and the antifreeze is isopropanol. Concrete component names and mass distribution are shown in Table 2:

[0086] Table 2

[0087]

Embodiment 3

[0089] The method for preparing the botanical fungicide in this example is roughly the same as in Example 1, except that the surfactant in this example is polysorbate or alkyl polyglycoside, the emulsifier is soybean oil, and the antifreeze is polyethylene glycol. diol. The specific component names and mass distribution are shown in Table 3:

Abstract

The invention relates to a botanical fungicide as well as preparation, use and storage methods thereof. The botanical fungicide comprises components in parts by weight as follows: 400-2,000 parts of wood vinegar, 0-50 parts of fructus cnidii, 0-50 parts of rhubarb, 0-50 parts of sophora flavescens, 1-10 parts of eugenol or a derivative of eugenol, 2-20 parts of an emulsifier, 2-20 parts of a surfactant and 10-100 parts of an antifreezing agent. The botanical fungicide has a remarkable sterilization effect, is pollution-free, cannot pollute water or environment and has low direct or indirect toxicity to a human body, the production process is simple and convenient, the production process is safe, and the botanical fungicide can be applied to modern organic agricultural production such as organic tea, organic vegetables, organic flowers, organic fruits and the like and has a good market prospect.

Description

technical field [0001] The present application relates to a fungicide used in agriculture, and in particular to a botanical fungicide used in organic agriculture, using wood vinegar as a carrier, and methods for its preparation, use and preservation. Background technique [0002] At present, the pesticides and fungicides used in agricultural production are generally chemical agents, which are likely to cause many problems such as environmental pollution, side effects of crop growth, pesticide residues, and drug resistance of pathogenic bacteria. Organic agriculture refers to the planting industry in which artificially synthesized fertilizers, pesticides, and growth regulators are completely or basically not used in the production process, and organic fertilizers are mainly used to meet the nutritional needs of crops. Clearly, the application of chemical agents to organic farming creates many problems. [0003] Therefore, there is a need to develop a non-chemical based pesti...
