During the past season many let- ters of inquiry have come to this de- partment asking for information con- cerning diseases of gladioli. Many growers are anxious to know how to control, or prevent the rot affecting the corms, which is so common and which in some cases causes serious loss. During the season of 1908 and 1909 the writer undertook an investi- gation of these diseases and succeeded, after some difficulty, in locating the organisms responsible for several types of disease. From quite similar types of rot three different fungi have been isolated, grown in pure culture and the diseases reproduced artificial- ly by inoculation. With two of these the inoculation experiments of last season have been repeated within the past month and the results seem con- clusive. The inoculated corms have in every case developed the rot in less than two weeks, while the check corms remained perfectly sound. I have now, therefore, no doubt that the fungi which we have located are the cause of the disease. A full de- scription of these diseases and the associated fungi will appear later in a bulletin of the Cornell Experiment Station. A very brief description with some notes was given in the Rural New Yorker March 19, 1910. Unfortunately we are unable as yet to give any definite information as to methods of control, and have not the time at our disposal necessary to per- sonally conduct experiments along of the points here mentioned and re- port results to us. The larger the number who can duplicate these ex- periments, the more reliable will be the conclusions to be drawn there- from. Judging from what we now know concerning the fungi causing these diseases, it does not seem probable that any method of spraying can be devis
