Abstract

Provided herein are compositions, systems, and methods for treating plant, aquatic, and/or livestock pathogens. More specifically, the present disclosure relates to activated compositions having metal nanoparticles and/or one or more organic acids for the treatment of harmful plant, aquaculture, or livestock pathogens, and also relates to methods of making and using the compositions.

Claims (28)

1. An activated composition for treating a plant pathogen, the composition comprising:

one or more metal nanoparticles, wherein the one or more metal nanoparticles are silver nanoparticles present in an amount of about 25 ppm to about 20,000 ppm, having a diameter ranging from about 1 nm to about 20 nm; and

one or more organic acids, wherein the one or more organic acids comprise tannic acid present in an amount of about 5 mM to about 30 mM, and citric acid or tri-sodium citrate present in an amount of about 1% w/v to about 40% w/v.

2. The composition of claim 1 , wherein the metal nanoparticles are present in an amount of less than 1% of the amount of the one or more organic acids.

3. The composition of claim 1 , wherein the metal nanoparticles are monodispersed via sonication, emulsification, surfactant, or similar suspension techniques.

4. The composition of claim 1 , wherein the composition is activated by excitation with sonication, a laser, an electron gun, or thermal excitation.

5. The composition of claim 1 , wherein the composition is formulated as a spray, a fluid matrix, a mist, a seed coating, or powder.

6. The composition of claim 1 , wherein the activated composition has increased viscosity compared to a non-activated composition.

7. The composition of claim 1 , wherein the activated composition remains stable for a period of at least 2 years.

8. A method of making an activated composition, the method comprising:

generating metal nanoparticles;

mixing the metal nanoparticles with one or more organic acids, wherein the metal nanoparticles are present in an amount of about 30 ppm to 20,000 ppm, and wherein the metal nanoparticles have a diameter ranging from about 1 nm to about 20 nm, and wherein the one or more organic acids comprise tannic acid present in an amount of about 5 mM to about 30 mM, and citric acid or tri-sodium citrate present in an amount of about 1% w/v to about 40% w/v; and

activating the composition via chemical reduction or excitation of the composition with energy using an energy source.

9. The method of claim 8 , wherein the energy source is sonication, a laser, an electron gun, or thermal excitation.

10. The method of claim 8 , wherein activating the composition comprises modulating the ionic, electronic, or quantum mechanics properties of the composition.

11. The method of claim 8 , wherein activating the composition comprises increasing electron ion activity in the composition, increases nanoparticle density, increases phonons, or increases a quantity of particle ions.

12. A kit, comprising:

a composition comprising:

one or more metal nanoparticles, wherein the one or more metal nanoparticles are silver nanoparticles present in an amount of about 25 ppm to about 20,000 ppm, having a diameter ranging from about 1 nm to about 20 nm; and

one or more organic acids, wherein the one or more organic acids comprise tannic acid present in an amount of about 5 mM to about 30 mM, and citric acid or tri-sodium citrate present in an amount of about 1% w/v to about 40% w/v; and

a dispensing apparatus capable of applying the composition to a plant.

13. The kit of claim 12 , wherein the dispensing apparatus is a spray bottle, a sprayer, a nozzle, or a drip line.

14. The kit of claim 12 , wherein the kit is a ready-to-use kit.

15. The kit of claim 12 , wherein the composition is a concentrated composition.

16. The composition of claim 1 , wherein the plant pathogen is a mold, mold spore, fungus, mutated fungus, fungi spore, bacterium mutated bacterium virus, mutated virus, nematode prior, or mutated prion.

17. The composition of claim 1 , wherein the plant pathogen is Fusarium oxysporum f. sp. Cubense or Mycosphaerella fijiensis.

18. The composition of claim 1 , wherein the composition further comprises acetic acid, oxalic acid, tartaric acid, succinic acid, maleic acid, fumaric acid, gluconic acid, malic acid, ascorbic acid, benzoic acid, palmitic acid, alginic acid, polyglutamic acid, naphthalenesulfonic acid, methanesulfonic acid, p-toluenesulfonic acid, naphthalenedisulfonic acid, polygalacturonic acid, malonic acid, sulfosalicylic acid, glycolic acid, 2-hydroxy-3-naphthoate, pamoate, salicylic acid, stearic acid, phthalic acid, mandelic acid, or lactic acid, or combinations thereof.

19. The composition of claim 1 , further comprising nanoparticles comprising gold, magnesium, zinc, calcium, manganese, copper, palladium, nickel, platinum, titanium, cerium, iron, thallium, molybdenum, or an alloy, oxide, hydroxide, sulfide, nitrate, phosphate, fluoride, chloride or combinations thereof.
