Example Embodiment
[0051] Example 1
[0052] A natural plant bactericide, its composition includes a neem extract 70wt%, a tea seed extract 15wt%, and a soapberry extract 15wt%, wherein the neem extract, tea seed extract, and no The extraction process of the ethanol extract of the soap locust is as follows:
[0053] Neem Seed Extract: Roughly select Neem Seed, stir and squeeze to remove the nucleus, coarse filter, and crush; Soak the crushed Neem Seed with organic ester solvent for 48h; ultrasonic beating for 8h; stand still for layering to extract the oil layer; add the extract Alkali saponification; filter, take the filtrate, decolorize and deodorize activated carbon, and concentrate to obtain the Neem Seed extract, the extraction rate can reach 38%;
[0054] Tea seed extract: first pierce and remove the hulls, select the tea seeds; squeeze the tea seeds, finely filter, and take the liquid; add alkaline protease, heat and saponify and hydrolyze; after high-speed dispersion, stand for layering, add h...
Example Embodiment
[0066] Example 2
[0067] The difference between this embodiment and embodiment 1 is that the composition of the natural plant fungicide in this embodiment includes 75wt% of Neem Seed Extract, 10wt% of Tea Seed Extract, and 15wt% of Sapindus Aromatica Extract. Among them, the mass ratio of the processed soapberry and the soap locust alcohol liquid in the extraction process of the soap locust alcohol extract is 75:25.
[0068] The natural plant fungicide provided in this example is sent to the Guangdong Province Microbiological Analysis and Testing Center for safety identification and antibacterial performance identification. The heavy metal content of the natural plant fungicide provided in this example is far lower than the national standard, and the antibacterial effect is good , Only a small amount can produce excellent antibacterial effect.

[0069] Example 3
[0070] A natural plant fungicide, its composition includes a neem extract 72wt%, a tea seed extract 12wt%, and a Sapindus japonica alcohol extract 16wt%, of which, the neem extract, tea seed extract,
[0071] And the extraction process of the ethanol extract of Soappindus serrata is as follows:
[0072] Neem Seed Extract: Roughly select Neem Seeds, stir and squeeze to remove the nucleus, coarse filter, and crush; Soak the crushed Neem Seeds with organic ester solvents for 24 hours; ultrasonic beating for 8 hours; stand for layering to extract the oil layer; add the extract Alkali saponification; filtering, taking the filtrate, decolorizing and deodorizing activated carbon, and concentrating to obtain a neem extract, the extraction rate can reach 34%;
[0073] Tea seed extract: first pierce and remove the hulls, select the tea seeds; squeeze the tea seeds, finely filter, and take the liquid; add alkaline protease, heat and saponify and hydrolyze; after high-speed dis...
