subjectAbstract

In vitro studies were conducted on the effect of temperature, pH and light levels on mycelial growth and spore germination of Fusarium oxysporum f. sp. spinaciae Sensitivity of 12 isolates were tested against Benomyl (50%WP) by food poisoning technique. Some of these isolates were resistant (NMU Fo 1) to fungicide whereas others were sensitive (Fol). Radial growth and spore germination of fungicide resistant and sensitive isolates were checked by using Czapek Dox Agar (CZA) medium. The results revealed that radial growth and spore germination was maximum temp at 25 °C, followed by 15 °C. Maximum radial growth & spore germination was found at 6.5, followed by 7.5 pH. Continuous light and white light were found ideal for maximum radial growth and spore germination of F. oxysporum. It was seen that the radial growth, spore germination of resistant isolate was higher than that of the sensitive one.
