Abstract
Diseases are major constraints to groundnut production in different parts of Odisha. The warm and humid climate of the coastal agro-ecological situation favors the initiation, development and subsequent spread of diseases. An investigation was conducted on the effect of temperature, relative humidity and pH on the mycelial growth of Leplosphaerulina crassiasca. Phoma microspora and Fusarium equiseti, the causal agents of foliar diseases of groundnut. The response of three test fungi varied, when exposed to different temperature regimes. Leptosphaerulina crassiasca and Fusarium equiseti could grow best at 30 C, whereas the optimum temperature requirement for Phoma microspora was 25 C. The growth of three test fungi was maximum at relative humidity of 90-100%. However, Fusarium equiseti could grow well even at 75.1% relative humidity. The effect of pH on the growth of test fungi suggested that all the three pathogens could produce maximum biomass at pH 6.0.
