ABSTRACT Several biotic and abiotic factors distress the pearl millet and significantly influence the production. Leaf rust, caused by Puccinia substriata, is the most important disease among the biotic factors, which reduced the yield up to 76 percent. Sphaerellopsis paraphysata is a rust mycoparasite with a wide host range that inhibits rust spore germination which could be cultured and could be grown on potato dextrose agar media. The effect of different carbon and nitrogen sources on the growth of S. paraphysata TNAU Sp1 showed that the dextrose and sodium nitrate supported the maximum mean mycelial growth and recorded 60.00 and 58.67 mm, respectively. Similarly, maximum mycelial growth and pycnidial production of S. paraphysata were observed at 20ºC (38.3 mm) temperature and 6.5 pH (55.0 mm). |
