Abstract
Aqueous liquid herbicide products include liquid fractions of water, acetic acid, fulvic acid, and a surfactant, and optionally citric acid. Salt is also dispersed in the liquid fractions to provide complete products which may be in the form of ready-to-use or dilutable concentrate herbicides. The herbicides may be directly applied to growing plants in order to quickly and effectively kill the plants.
Claims28
A ready-to-use liquid herbicide, comprising a liquid fraction including water, acetic acid, fulvic acid, and a surfactant.
A dilutable liquid herbicide concentrate, said concentrate comprising a liquid fraction including water, acetic acid, fulvic acid, and a surfactant.
A method of preparing a liquid herbicide composition, comprising the steps of:
- mixing humic raw material powder with an excess of hot water at a temperature of from about 150-250° F., and respective quantities of vinegar and acetic acid powder to create a mixture;
- mechanically blending said mixture for a period of from about 8-24 hours to yield an intermediate product having an acidic pH;
- screening said intermediate product to remove humic acid, humin, ash, clay, and silt solids;
- placing said screened intermediate product in a settling tank for a period of from about 5-30 days, and causing lower molecular weight species to rise to the top of said tank, with heavier molecular weight fulvic acid species descending towards the bottom of the tank;
- subjecting the heavier molecular weight fulvic acid species to an osmosis process to give a fulvic acid concentrate containing from about 3-9% fulvic acid by volume;
- mixing together said fulvic acid concentrate and said lower molecular weight species from said tank to give a product;
- adding surfactant to said product;
- and
- adding an amount of sodium chloride to said surfactant-added product.
