The head of corn v;as found in V/ashingtcn. Accordin to Zundel, in one field near Pullman, 203 of the plants v/ere infected. The disease also v/as found in Yakioa County v/here considerable corn is Dana states that the disease probably is spreading in V/ashington. Mo head snut v;as observed on corn in California although Iv'ackie is of the opinion that it undoubtedly is present this year as it has been in the past. Seedling blight caused by Helninthosporium sp. A species of Helminthos- porium isolated from living corn plants, according to Stover, v/as found to cause a marked seedling blight of corn. The results of prelij:iinary experiments are summarized in an abstract presented at the Toronto mieeting. (Stover, V*'. G. The relation of soil temperature to the development of the seedling blight of corn caused by Helminthosporium sp. (Abstract). Phytopath. 12: Jan. 1922.) RICE Straighthead (non-parasitic) Straighthead of rice was reported from South Carolina, Louisiana, Texas, and Arkansas, Pig. 62. Ludv;ig states that severe local injury probably occurred in South Carolina. Edgerton states that the disease was of considerable importance in Louisiana, al- though the aggregate loss probably v/as not very great. Taubenhaus estimates that the yield v/as reduced by 50 in Texas, and Elliott estimates that the Arkansas yield v/as reduced by approximately 2o. Fig. G2. Occurrence of and percentage loss from straighthead (uppe
