SMUT AND OTHER CORN DISEASES

The diseases encountered in corn most often were the molding of the sown seeds and of the sprouts, blister smut, bacteriosis, fusariosis and white- ear disease. Gray rot developed less intensively. The stalk rots caused by a complex of microorganisms and also diplodia disease and red rot had a limited occurrence. The molding of the seeds and sprouts was caused by fungi of the genera Penicillium and Fusarium. Owing to a late spring it was less severe than usually in most of the regions. An appreciable development of the disease was observed in Siberia and other regions of the USSR.
