ABSTRACT
Myrothecium roridum is a disastrous pathogen of grain, fruit and vegetable crops including cucurbits. It has been reported to parasitize a number of crops in Pakistan. To find out the cucurbitaceous host range of the fungus, pathogenicity was done on eight cucurbit species in controlled conditions. The results reveal that M. charantia, C. melo, C. sativus L. and C. lanatus are least resistant hosts of this disease with D.I. of 49.84, 48.21, 45.25 and 44.86% respectively. On the other hand three vegetables species viz. L. aegyptaca (17.61%), L. siceraria (22.72%) and C. pepo (23.57%) showed least resistance. One species i.e. P. fistulosus (38.13%) showed moderately susceptible response. All the results were evaluated by using M.STAT software under completely randomized design.
Keywords: Myrothecium roridum, cucurbits, host range, water melon, Bitter gourd, sponge gourd, muskmelon, cucumber.
