In the present study, corn meal agar was found as the best medium for growth of Drechslera spicifera , a pathogen of water hyacinth. Small water hyacinth plants exhibited a smaller number of lesions/leaf when inoculated with D. spicifera compared with inoculated medium and large plants. However, percentage total diseased area/leaf was almost the same among the different plant sizes. The pathogen did not interfere with the vegetative plant growth, since, both infected and healthy water hyacinth plants of the same age showed similar percentages of new leaf growth. Leaf diffusates of water hyacinth plants significantly reduced conidiospore germination in D. spicifera.
