Losses from dry rot were reported as followsl 7 per cent, Iowa; 3 Pei' cent, Florida; 2 per cent, Ohio and Missouri; 1*5 pei* cent, Indiana; 1 per cent, Mar:7land and Kansas* In Florida the losses are com** plicated by other species of Diplodia* It was estimated that two other species caused 2*5 per cent loss. In Missouri it was thought that the early s|3ritig weather was too cool, and in Kansas it was reported that July and September were too dry for development. In both of these states the disease was less prevalent than usual. ROOT ROTS and EAR ROTS (caused by various fungi)* pibberella saubinetii, Pythium sp*, and Fusarium spp. were mentioned as being associated with Or caus-^ ing root or stalk rots* Estimated losses are given in tables I5 and I6* I^e root rot situation still remains very explicated^ and it is desirable that in- vestigators of this problem attempt to discover and evaluate the importance of the causes more exactlyt From the disease survey standpoint it would he helpful if the various diseases here concerned, including ear rot, could be separated out on the basis of s^^mptoms, and without respect to causes It that were done we might have somethin£- like the followihgt root rot^ seedling blight, and ear rot. In general the I525 season did not seem to be especially favorable for development of these troubles, as only South Carolina out of eighteen states reporting mentioned them as more pr
