Pycnidtospores were released in the form of cirrus through ostioles. Rain spalsh has a vital role in the dispersal of spores. Multidirectional traps were used for collecting spores carried by rain splash. Though pyclndiospores could be trapped at distances upto 120cm horizontally and upto 75cm vertically from the infection foci, the number of spores caught was higher at closer distance. Spores could also be collected from the dew-drops daring morning hours. The importance of this phenomenon in disease incidence is discussed.enArticle
