Physiological studies on Lasiodiplodia theobromae and Fusarium solani, the cause of Shesham decline

Optimum temperature for the growth of the Fusarium solani and Lasiodiplodia theobromae fungi was 25 ºC. It was found that continuous light was more suitable than continuous darkness (24 hours) and 12 hours light plus 12 hours darkness for the growth of fungi. Two media were evaluated for best growth of the fungi i.e. Fusarium solani and Lasiodiplodia theobromae, Fusarium solani grew maximum on Poatao Dextrose Agar (PDA) medium but least grew on the water agar medium. Both the fungal species gave the best mycelial growth on PDA medium as compared to water agar medium.
