Fungicides and Bioagents: Evaluation of Pathogen Eradication under Laboratory Conditions

Abstract

In an in-vitro study evaluating eight different fungicides against C. musae, carbendazim, carbendazim 12% + mancozeb 63%, and azoxystrobin 11% + tebuconazole 18.3% exhibited 100% inhibition of fungal growth at concentrations of 0.1%, 0.25%, and 0.1%, respectively. Propiconazole (0.05%) was also the most effective fungicide, showing 83.03% mycelial inhibition, followed by carboxin 37.5% + thiram 37.5% (73.51%) and chlorothalonil (76.84%) at concentrations of 0.25% and 0.2%, respectively. Mancozeb exhibited the minimum mycelial inhibition (66.44%) at a concentration of 0.25%, while copper oxychloride showed the least inhibition (48.96%) at 0.25% concentration. In addition, five biocontrol agents were screened for linear growth inhibition of C. musae through the dual culture method. Among the Trichoderma isolates, T. harzianum demonstrated the highest growth inhibition (84.38%), followed by Pseudomonas fluorescens (80.16%).
