Efficacy of radio frequency dielectric heating for fungal inhibition in sugarcane cuttings: an investigation into sustainable agricultural practices

Abstract

This study explores the efficacy of radio frequency (RF) dielectric heating as a non-chemical alternative for controlling fungal infections in sugarcane cuttings. Utilizing an innovative experimental setup, the research investigates the impact of various electric field intensities (115 kV/m, 150 kV/m, and 225 kV/m) and temperatures (70°C, 90°C, and 110°C) on fungal growth inhibition. The methodology involves exposing sugarcane cuttings placed between parallel electrode plates to controlled RF heating, with the goal of determining optimal conditions for fungal suppression without compromising the integrity of the plant tissue. The results indicate that higher temperatures combined with increased electric field strengths significantly enhance the inhibitory effects on fungal growth. The findings suggest that RF heating could be a viable method for sustainable fungal management in agriculture, reducing reliance on chemical fungicides and minimizing environmental impact. The study not only confirms the potential of RF dielectric heating in agricultural settings but also sets the stage for further research into scalable applications and long-term effects on plant health.
