Effect of fungicides and phytoextracts on spore germination of Alternaria burnsii

Abstract

An experiment was conducted on cumin crop and the treatment set of fungicides and phytoextracts
were tested for their inhibitory effect on spore germination of Alternaria burnsii causing cumin blight
was performed in in vitro condition. In the laboratory screening of non systemic fungicides, mancozeb,
zineb, ziram and chlorothalonil were found most effective in spore germination inhibition of A.
burnsii. Among systemic fungicides, hexaconazole and tebuconazole were found most effective in
the reduction of spore germination of blight pathogens. Turmeric rhizome, garlic clove and ginger
rhizome extracts proved to be the best sources of plant origin for the inhibition of spore germination
of blight pathogen.
