Abstract
Early blight in solanaceous plants is a common and serious disease of potato and tomato caused by the pathogen Alternaria solani. Leaf blight caused by A. solani resulted in 50–80 % yield loss. Several fungicides have been used for a long time to prevent losses due to pre- and post-harvest diseases but have led to serious environmental threat to human life and microbial contamination. Therefore, the present study was done with the aim to analyse the effect of acetone extract of leaf and alcohol extract of inflorescence of Euphorbia pulcherrima on spore germination of A. solani by detached leaf assay method for the development of biologically safe fungicide. A significant reduction in infection as well as conidial germination of A. solani was observed on petiolated but detached leaves of Lycopersicon esculentum. Acetone extract of the leaf of E. pulcherrima was found to be 100 % inhibitory at 125 µg/ml concentrations whereas alcohol extract of inflorescence showed 100 % inhibition of spores at only 62.5 µg/ml concentration.
