Pathogenic Variability of Soybean Charcoal Rot Caused Macrophomina phaseolina Isolates against Pulse Crops

Macrophomina phaseolina is the most devastating, emerging and root killer pathogen which causes charcoal rot and root rot diseases in various economically important crops. Macrophomina phaseolina 16 isolates of soybean collected from various districts of Madhya Pradesh state Pathogenic variability among the 16 isolates of Macrophomina phaseolina to test line of susceptible varieties of different host crops as soybean, chick pea, mungbean, urdbean and cowpea, were used to check wide range host. The parameters can be observed from experiment Root Index, Mortality, Root Mortality Per unit, Avirulent Virulent, higly Virulent. To avoid crop rotations of soy bean with any pulse crop for future.
