[0032] Example 1 Preparation of Plant Virus Inhibitor Water (KBD Water)
[0033] 1. Preparation of component A: Take 2.5 kg of Polygonum cuspidatum, crush it to 60 mesh, add 12.5 kg of 70% ethanol, soak for 2 hours, extract the supernatant at 45°C for 2 hours, centrifuge and remove the solvent at 45°C , The volume was set to 5 kg with 70% ethanol, and the Polygonum cuspidatum extract (component A) was prepared for use.
[0034] 2. Preparation of component B: Take 2 kg of soybeans and hydrolyze under alkaline conditions of pH=11 to obtain 4 kg of vegetable protein hydrolysate, namely vegetable protein amino acid solution, and then add 5 kg of saponins extract and 1 kg of tea soap (Note: The saponins extract and tea saponin are both produced by Zhejiang Dongfang Tea Science and Technology Co., Ltd.), mixed evenly to prepare a plant-based surfactant (component B).
[0035] 3. Preparation of plant virus inhibitor: mix 5 parts of component A, 3 parts of component B, and 2 parts of water ...

[0036] Example 2
[0037] 1. Preparation of component A: Take 1 kg of Polygonum cuspidatum, crush it to 60 mesh, add 10 kg of 70% ethanol, soak for 1 hour, extract the supernatant at 45°C for 5 hours, centrifuge and remove the solvent at 45°C , The volume is adjusted to 2 kg with 70% ethanol to prepare Polygonum cuspidatum extract (component A) for use.
[0038] 2. Preparation of component B: Take 2 kg of soybeans and hydrolyze under the alkaline condition of pH=10 to obtain 5 kg of vegetable protein hydrolysate, namely vegetable protein amino acid solution, and then add 6 kg of saponins extract and 9 kg of tea soap (Note: The saponins extract and tea saponin are both produced by Zhejiang Dongfang Tea Industry Technology Co., Ltd.), mixed evenly to prepare a botanical surfactant (component B).
[0039] 3. Preparation of plant virus inhibitor: mix 1 part of component A, 3 parts of component B, and 6 parts of water to make 10 kg of water-based KBD.
