Summary

The pathogenT. maculans inciting leaf spot of turmeric perpetuates in the form of ascospores and conidia and incites first infection on the lowermost leaves, in October and November when the atmospheric humidity prevails about 80 % with 21°–23° C temperatures. The secondary infection is due to availability of large potential of inoculum of ascospores and conidia frequently and periodically produced by the pathogen under cool temperature conditions (20°–24° C) with about 80 % atmospheric humidity. Plant debris, rhizomes etc. of the previously affected crop or soil from the fields where turmeric crop was taken in the previous season do not serve the primary source of infection.
