Nano Tools for Managing Plant Diseases

This BIOAg blog post highlights research exploring cellulose nanofibers (CNFs) as a potential tool for managing plant diseases in agriculture. CNFs are microscopic fibers derived from plant cellulose that possess unique physical properties, including low weight, elasticity, and high surface area. These characteristics make them useful in many industries and increasingly promising for agricultural applications.

Researchers at Washington State University are investigating whether CNFs can help manage diseases affecting potato crops, including early blight, late blight, silver scurf, and powdery scab. Preliminary research suggests that applying CNFs to plant surfaces may reduce disease severity caused by fungal and bacterial pathogens. CNFs may also function as adjuvants, improving the adhesion and effectiveness of other crop protection products. Additional studies suggest CNFs could enhance soil properties such as nutrient retention and erosion resistance.

The BIOAg-funded research aims to evaluate whether cellulose nanofibers could support biologically intensive pest management strategies that are renewable, non-toxic, and practical for growers.
