Abstract
Some embodiments relate to herbicide compositions and methods of inducing phyotoxicity in a plant, by administering an aqueous composition to foliar portions of the plant. This aqueous composition includes at least one nutrient, and at least one adjuvant, and has a pH of about 4 to about 7. In some embodiments, the aqueous composition comprises an organic or mineral acid. In some embodiments, the phytotoxicity is topical. In some embodiments, the phytoxicity is systemic. Without being limited by theory, the nutrient is absorbed by the plant in excess, thereby killing the plant.
Claims16
A method of inducing phytotoxicity in a plant, the method comprising:
- administering an aqueous herbicide composition to foliar portions of the plant, wherein the aqueous herbicide composition comprises:
- a nutrient, which is potassium;
- and
- an adjuvant;
- and
- wherein the nutrient has a concentration of 1 M to 2.5 M in the aqueous herbicide composition and a pH of the composition is 3.5 to 7;
- and
- retaining the aqueous herbicide composition on the foliar portion of the plant for about 1-5 days,
- wherein the nutrient is absorbed systemically by the plant in an amount effective to cause terminal physiological disruption and killing of the plant.
