Abstract
In vitro study, pathogenicity test of the isolate, Gibbago trianthemae which causes leaf spot and blight disease on horse purslane was confirmed. Study revealed that G. trianthemae is highly pathogenic to horse purslane as evidenced by the rapid rate of infection and colonization of the host. The test plants inoculated with 5x104 spores/ml concentration showed high susceptibility to G. trianthemae incheding of crops only. Foliar pathogen G. trianthemae might be useful as a mycoherbicide to control its host weed.
