The pathogenic effects of Ustilago maydis (DC) Corda to five maize cultivars and four other plants were studied. It was found that none of the maize cultivars tested was resistant to the common smut disease whereas cultivars Balady was slightly susceptible. Only Sorghum rulgare from the other tested plants showed moderate susceptibility to the disease. With respect to gall formation only cultivars Giza 2 and single cross hybrid 10 formed galls after 2 weeks. The pure toxic material (Ustizeain) from Ustilago maydis was obtained, it caused chlorosis and necrosis on detached maize leaves, but it had no effect on growth of some fungi tested. Sporidia treatment showed also chlorosis on detached maize leaves.
