Illinois: University of Illinois, 1930. — 164 p. — (Bulletin (University of Illinois (Urbana-Champaign campus). Agricultural Experiment Station) - no. 354).The material in this bulletin is designed especially to give the agricultural teacher and student, the farm adviser, and the interested farmer specific information concerning the extent and nature of corn diseases in this state, how they may be recognized, and how they may be held in check in so far as practical control measures are known. While it is impossible at the present time, even experimentally, to grow corn plants in any number to maturity free from disease, an important saving by partial disease control is available to all. Probably present losses could be cut in half by the application of methods already developed and known to be effective.Introduction.
