Abstract:
Safflower (Carthamous tinctorius L.), is one of the most important Rabi oilseed crop of the family compositae or asteraceae in India. It is affected by several fungal diseases among them the dry root rot caused by Macrophomina phaseolina which cause severe economic yield loss. An attempt was made to manage the disease with fungicides. In vitro efficacy of seven systemic fungicides @ 500 and 1000 ppm, seven Non-systemic fungicides @1500 and 2000 ppm and seven combi-fungicides @ 1500 and 2000 ppm tested in vitro were found effective with significant mycelial growth inhibition of the test pathogen, over untreated control. However, resulted with cent percent inhibition Carbendazim 50% WP (100% and 100%), Mancozeb (86.67% and 94.00%), Carbendazim 25% + Mancozeb 50% (100% and 100%) and Carbendazim 12% + Mancozeb 63% (92.03% and 100%) were found most effectives against M. phaseolina.
