Abstract


Pathogenicity tests of various species of Pythium, Fusarium and Rhizoctonia sotani were made on five plants namely cotton, pea, tomato, maize and wheat. Pythium ultimum proved to be the most destructive species to tomato and cotton seedlings. The four species of Fusarium tested showed considerably different pathogenic abilities. Isolate of Rhizoctonia soleni (A — from soil) showed slight pathogenicity to all test plants and isolate (B — from cotton seedlings) was highly destructive to cotton and pea.
