Benefits of technology

The invention helps save money by making it less expensive than traditional methods like cooking or washing clothes instead.

Problems solved by technology

This patented technical problem addressed in this patents relates to controlling vegetative cells that form underground rottings during crop cultivations without harmful consequences from external agents like germanes. Current methods involve treatments involving various substances including antibiosis drugs, nutrients, organisms, mineral acids, salts, enzymes, yeasts, cytozoa sporans, Bacillaria sppies, nematodes, phytophiles, polysaccharidase proteins, lignocysteine hydrolyzing protein family members, lycopene beta synthesis gene products, quaternary ammonium salt compounds, chloroform acid esters, carboxylic acids and alkoxylamines.

Embodiment 1

[0032] A preparation method of a composition for preventing tobacco bacterial wilt, characterized in that the steps are as follows:

[0033] (1) Preparation of ginger extract: Dry the ginger, crush it, extract it twice with methanol at a ratio of 1:5, filter, and concentrate the filtrate under reduced pressure with a rotary evaporator below 30°C to obtain an extract, and store it at low temperature for later use;

[0034] (2) The preparation of the extract of Sapindus chinensis, dry Sapindus chinensis, crush, extract three times with water at a ratio of 1:5, filter, and concentrate the filtrate under reduced pressure with a rotary evaporator below 30°C to obtain an extract, and store it at low temperature spare;

[0035] (3) Preparation of spinosaurus extract: Dry spinosaurus, crush, extract three times with ethanol at a ratio of 1:3, filter, and concentrate the filtrate under reduced pressure with a rotary evaporator below 30°C to obtain an extract. Save for later use;

Abstract

The invention discloses a preparation method of a composition for preventing tobacco bacterial wilt: (1) preparation of ginger extract; (2) preparation of Sapindus japonica extract; (3) preparation of spinach extract; ( 4) The preparation of the extract of the leaves of the black rice tree; (5) according to the parts by weight, take 8‑12 parts of the ginger extract, 3‑5 parts of the Sapindus japonica extract, 2‑3 parts of spinosa, and the leaf extract of the black rice tree 2-4 parts, 0.5-0.9 parts of wood vinegar, and 100 parts of purified water are mixed to obtain the plant extract of the composition for preventing tobacco bacterial wilt. Results: The effect of inducing resistance activity was 70.2‑92.3%. One month after topping, compared with the incidence rate of 53.5% in the control group, the incidence rate of flue-cured tobacco treated in this embodiment was only 6.3-10.8%, and the control effect was 51.2-69.8%.
