Abstract

Embodiments of the present disclosure, in one aspect, relate to compositions including a vacancy-engineered (VE)-ZnO nanocomposite, methods of making a composition, methods of using a composition, and the like.

First claim

What is claimed:

1. A method, comprising:
applying a composition to a plant enabling entry of the composition via at least one of roots, vascular system and leaf stroma of the plant;
transporting the composition through a vascular system and on a surface of the plant, wherein the composition has comprises a vacancy-engineered (VE)-ZnO nanocomposite including a plurality of interconnected VE-ZnO nanoparticles, wherein the plurality of interconnected VE-ZnO nanoparticles has a plurality of surface defects associated with an oxygen vacancy, wherein the VE-ZnO nanoparticles have a plate-like structure and wherein each of the VE-ZnO nanoparticles has a diameter of other than about 3 to about 8 nanometers; and
killing a substantial portion of a microorganism or inhibiting or substantially inhibiting the growth of the microorganism on the surface or within the plant, wherein the composition is non-phytotoxic to the plant.

2. The method of claim 1 , wherein the microorganism is a bacterium.

3. The method of claim 1 , wherein the microorganism selected from the group consisting of E. coli, B. subtilis, Xanthomonas sp, Candidatus Liberibacter spp , and S. aureus .

4. The method of claim 1 , wherein applying includes application of the composition to a growth substrate in which the plant is growing.

5. The method of claim 4 , wherein the growth substrate is soil surrounding the plant.

6. The method of claim 1 , wherein applying includes forming a film of the composition on the surfaces of the plant.

7. The method of claim 6 , wherein the film forms a substantially uniform plant surface coverage.

8. The method of claim 1 , wherein applying includes disposing the composition on the surface of the plant.

9. The method of claim 1 , wherein applying includes injecting a part of the plant with the composition in a fluid.

10. The method of claim 9 ,. wherein the part of the plant is a stem.
