COMPOSITIONS AND METHODS FOR TREATING PLANT DISEASES

摘要

Nanoparticle compositions for treating citrus greening disease and other plant diseases include a liquid or gel carrier and metal nanoparticles dispersed therein. The metal nanoparticles can be spherical-shaped and/or coral-shaped. Methods of treating plant diseases include applying a nanoparticle composition to an infected plant part to kill the microbe causing the disease. The method may further include removing an infected plant part, such as a branch, treating the infected plant part with a nanoparticle composition, and grafting the plant part (branch) back onto the plant. The plant may particularly be a citrus tree.

1. A nanoparticle composition for treating plant disease, comprising:
a carrier; and a plurality of non-ionic metal nanoparticles having a mean particle size in a range of about 1 nm to about 25 nm and a particle size distribution so that at least 99% of the metal nanoparticles have a particle size within 30% of the mean particle size.
