Show r Blight o Unlikely I IThe The possibility of losing a acorn acorn acorn corn crop in the corn belt states to Southern Leaf Bli ht in May Mayor or June is remote THIS IS the conclusion of scientists who completed a series of field ex experiments r- r at the research research re- re search farm in Florida Their findings agree web wih earlier season blight was iu w urn likely IN THE experiments scientists infected healthy susceptible susceptible susceptible sus sus- T cytoplasm corn seedlings seedlings seedlings seed seed- lings with Southern Corn Leaf Blight Between Jan 19 and Feb 19 ten groups of seedlings were inoculated Theoretically all that was required 9 ired at this point to cause blight to spread was the environmental factors of temperature and humidity THREE OK Ox O four days ays after each inoculation typical blight lesions developed on the seed seed- lings But the critical finding finding finding find find- ing was that these lesions never produced spores nor did they cause lesions on untreated corn seedlings used as a check Thus despite the favorable temperature and humidity factors factors factors fac fac- tors for infection which were comparable comparable to late springtime conditions in the midwest the researchers found that the blight did not spread THIS IS definite evidence they feel that the blight if it occurs at all will not strike early M |
