Eight culture media, eight temperature levels, nine pH levels, seven carbon and six nitrogen sources tested exhibited better growth of Alternaria carthami. Results revealed that Potato dextrose agar gave significantly highest growth (90.00 mm), followed by Potato malt agar (84.16 mm) with excellent sporulation. Temperature levels indicated that highest mean mycelial growth (85.66 mm) was recorded at 30°C followed by 25°C (83.83 mm) and 20°C (66.33 mm). However, maximum mean mycelial growth (85.83 mm) was recorded at pH 6.5 with excellent sporulation, followed by at pH 6 (82.00 mm) and pH 7 (70.33 mm) with excellent and good sporulation, respectively. The carbon sources exhibited varied radial mycelial growth and sporulation of the test pathogen. However, highest radial mycelial growth (86.00 mm) and excellent sporulation was recorded on glucose, followed by on maltose (82.83 mm) and starch (80.33 mm) with excellent sporulation. Nitrogen sources resulted highest radial mycelial growth (82.55 mm) and excellent sporulation on potassium nitrate, followed by on peptone (75.83 mm) with good sporulation. Least radial mycelial growth (19.00 mm) was recorded on urea with poor sporulation.Keywords

Survey was conducted in four districts of Marathwada region of Maharashtra during Rabi 2013 to know the incidence and intensity of leaf blight disease caused by Alternaria carthami. The disease was predominant in all the districts surveyed. Highest per cent disease incidence and intensity was reported in Hingoli (42.08 and 38.46 %, respectively). This was followed by Nanded (40.07 and 36.03 %, respectively).Keywords
