Effect of Different Media and Temperature on the Growth of the Exserohilum turcicum Incitant of Turcicum Leaf Blight in Maize

The effects of temperature and media on the growth of Exserohilum turcicum were investigated. The Eight isolates were grown on four different solid media viz., PDA, MLE, PCAand PDA+Yeast medium and incubated separately at three different temperatures (20[degrees]C, 25[degrees]C and 30[degrees]C) to...

Summary:The effects of temperature and media on the growth of Exserohilum turcicum were investigated. The Eight isolates were grown on four different solid media viz., PDA, MLE, PCAand PDA+Yeast medium and incubated separately at three different temperatures (20[degrees]C, 25[degrees]C and 30[degrees]C) to study their effect on the growth of the E. turcicum. Among the media tested, potato dextrose agar supported good growth of the fungus followed by maize leaf extract and potato carrot agar, while least growth was observed on Yeast + PDA medium with some exceptions. As the temperature increases from 20 to 25[degrees]C and 25 to 30[degrees]C there was increase in the colony diameter of all the isolates on four tested media. There were significant differences in the growth of the fungus at different temperatures.
