Adaptability of Macrophomina phaseolina and Fusarium oxysporum to Different Temperature and pH Causing Stem-Root Rot and Wilt Diseases of Jute

Abstract

In order to ascertain the impact of physiological parameters like temperature and pH on growth and sporulation of M. phaseolina and F. oxysporum, causing stem-root rot and wilt diseases of jute, an experiment was conducted to examine. It was discovered that Fusarium oxysporum thrived at pH 5 (80.135 mg) while Macrophomina phaseolina grew best at neutral pH, or pH 7 (69.065 mg). M. phaseolina grows best at temperatures ranging from 35 °C to 30 °C, with no growth observed at lower temperatures. Fusarium oxysporum's growth peaked at 25 °C (90.00 mm), and it significantly decreased below 15 °C and above 40 °C. In response to changes in temperature, fungal development slows.
