Abstract

The disease commonly referred to as Macrophomina blight has emerged as a noteworthy hindrance to the profitable and prosperous mungbean farming in Madhya Pradesh in recent times. In vitro conditions were used to evaluate the efficacy of eight different single and combination fungicides against Macrophomina phaseolina. The findings showed that the most effective fungicides were Tebuconazole 25.9EC, Mancozeb 75% WP and Carbendazim 50% WP. These fungicides completely inhibited mycelia growth of M. phaseolina at all concentrations (300, 600, and 900 ppm). All combination fungicides were found effective for mycelia growth inhibition of M. phaseolina under in vitro condition. Vitavax (Carboxin 37.5% + Thiram 37.5%WS), Saaf (Carbendazim 12% + Mencozeb 63%WP) and two new generation fungicide combination trade name as Xelora (Thiophenate Methyl 450 + Pyrachlostrobin 50) and Juniper (Mencozeb 64% + Thiophenate Methyl 12%WP) were found to be most effective at all concentrations used and shows 100% inhibition of the fungus

Conclusion

The disease known as Macrophomina blight has emerged as a significant obstacle to the lucrative and successful cultivation of mungbean in Madhya Pradesh in recent years. The effectiveness of many fungicides against Macrophomina phaseolina was assessed under in vitro condition. The most successful single fungicides that completely inhibited M. phaseolina radial growth were carbendazim 50% WP, mancozeb 75% WP, and tebuconazole 25.9EC. The most effective combination fungicides were found to be Vitavax (Carboxin 37.5% + Thiram 37.5%WS), Saaf (Carbendazim 12% + Mencozeb 63%WP), Xelora (Thiophenate Methyl 450+ Pyrachlostrobin 50) and Juniper (Mencozeb 64% + Thiophenate Methyl 12%WP)
