Study on Evaluation of the Efficacy of Different Fungicides against Fusarium musae, a Fruit Rot Disease of Banana

Due to the paucity of research on fusarium fruit rot diseases of banana and their management in India, it is thought worthwhile to conduct research on fusarium fruit rot diseases of banana and their management in south Gujarat in order to extend the shelf life of banana fruits and reduce losses caused by post-harvest diseases. As a result, the current investigation was launched. In this study, nine fungicides were tested against F. musae using the poison food technique on PDA medium at various concentrations. Mancozeb 75 WP at 2500ppm, azoxystrobin (20%) + difenoconazole (12.5%) at 1000ppm, and propiconazole (25 EC) at 500ppm and 1000ppm were found to be the most superior because they completely inhibited F. musae mycelial growth In vivo, the lowest fusarium fruit rot severity was found with propiconazole (25 EC) at 1000ppm in pre (6.61 percent) and post-inoculation (6.7 percent) treatments at 8 days after inoculation in pre (6.61 percent) and post-inoculation (6.7 percent) treatments at 8 days after inoculation. At 8 days after inoculation, azoxystrobin (20%) + difenoconazole (12.5%) at 500ppm and chlorothalonil (75 WP) at 2500ppm were shown to be the least efficient in decreasing the severity of fusarium fruit rot in pre and post inoculation treatments.
