EFFECT OF SCLEROTIAL INOCULUM DENSITY OF MACROPHOMINA PHASEOLINA ON CHARCOAL ROT OF SUNFLOWER
SHAHNAZ DAWAR AND ABDUL GHAFFAR
Abstract
Infection and colonization of Macrophomina phaseolina increased significantly (p<0.05) with the increase in sclerotial population in soiL No significant difference in shoot length was observed in different treatments. In seed inoculation experiment, size of inoculated plants was significantly smaller than the uninoculated plants (p<0.001). Infection of root by M. phaseolina was significantly greater in treated plants as compared to control (p<0.05) which showed significant increase with the increase in time (p<0.001).
