 ABSTRACT

Dry root rot caused by Macrophomina phaseolina is of wide occurrence in sandy soil of Rajasthan where climatic conditions are dry and temperature remains high. Dry root rot is the most devastating disease in all the mungbean growing districts of Rajasthan particularly in Bikaner, Jaipur, Bhilwara, Bharatpur, Sri Ganganagar, Jodhpur, Kota and Udaipur. In the present investigation ten isolates of Macrophomina phaseolina were tested for their pathogenic nature, using susceptible RMG-62 variety of mungbean. The dry root rot incidence (%) in sterilized soil and unsterilized soil varied from 33.33 to 100 and 26.67 to 83.33, respectively. Isolate Bikaner was most virulent followed by Churu, Hisar, Sri Ganganagar, Junagarh-6486, IARI-5156, Sawaimadhopur, Delhi, Jalana-5156 and Narnaul. Bikaner isolate showed 83.33 per cent disease incidence in unsterilized soil which was less than sterilized soil i.e 100 per cent.
Key words: Macrophomina phaseolina, Dry root rot, Mungbean, Incidence (%).
