Efficacy of systemic and non-systemic fungicides against Macrophomina phaseolina (Tassi) Goid causing mungbean blight

Abstract

Eight systemic and Twelve non systemic and contact fungicides were evaluated (each (@ 500, 1000, 1500 ppm and 1500, 2000 2500 ppm respectively), in vitro against Macrophomina Phaseolina. All the fungicides tested caused significant inhibition at all six concentrations tested over untreated control. Average mycelial inhibition with all the systemic fungicides tested was ranged from 40.11 (Fosetyl-AL) to 100 (Carbendazim and Hexaconazole) percent. However, significantly highest average mycelial inhibition was recorded with the fungicides Carbendazim and Hexaconazole (100%) and the Fungicide Fosetyl-AL was found comparatively less effective with 40.11 percent inhibition, of the test pathogen. Average mycelial inhibition with all the non systemic and contact fungicides tested was ranged from 12.05 (Copperoxy chloride) to 100 (SAFF) percent. However, significantly highest average mycelial inhibition was recorded with the fungicide SAFF (100%). This was followed by Nativo (95.35%), Ridomil-Mz (93.14%), Curzet (91.75%) and fungicides Copperoxy chloride, Propineb and Copper hydroxide were found comparatively less effective with maximum mycelial inhibition of 12.05%, 17.12% and 23.03%, respectively.
