| Abstract | Cercospora citrullina, isolated from pumpkin plant (Cucurbita maxima), initially could not produce conidia whencultured on potato dextrose agar, but was able to produce conidia when cultured on oatmeal agar, oat grain agar, wheat grain agarand barley grain agar. C. citrullina also produced conidia when cultured in substrates such as oat grain, wheat grain, barley grainand Trichosanthes sp. dried leaves. Trichosanthes sp. dried leaves induced the highest conidia production (4.81 ? 103conidia /ml) while oatmeal agar and barley grain agar yielded the best result among the agar media by inducing 1.23 ? 103conidia / mleach. Overall, continuous darkness condition was better than other lighting conditions (12 h near UV black light plus 12 hdarkness condition; and 12 h fluorescent white light plus 12 h darkness lighting condition). Lastly, inoculation of C. citrullinaonto cucurbit plants was successfully conducted by sandwiching inoculum between leaves and plastic cards. |
