Embodiment 1

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

[0075] Table 1

[0076]

[0077] The specific preparation method is:

[0078] (1) the preparation of refined wood vinegar liquid: the oak wood is carried out dry distillation, obtains wood vinegar stock solution after the gas condensed during dry distillation; wood vinegar stock solution is left standstill for 6 months after tar precipitation, get clear upper layer wood vinegar liquid; The upper layer wood vinegar is subjected to vacuum distillation under the conditions of a temperature of 90° C. and a pressure of 0.12 Mpa, and the distillation is carried out until the volume of the distillate is 80% of the original volume to obtain a refined wood vinegar.

[0079] (2) Preparation of botanical fungicide:

Embodiment 2

[0085] The method for preparing the plant-derived 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 fatty acid polyoxyethylene ester, and the antifreeze is isopropyl alcohol. The specific 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 that 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. 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 for agriculture, and in particular, to a plant-derived fungicide that is used in organic agriculture and uses 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 easily 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 synthetic fertilizers, pesticides and growth regulators are not used at all or basically 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 pesticide fungicide s...
