However, as will be seen later, the late blight does not confine its ravages to the field, but extends its destructive action to the storage coop, or cellar, and as the disease has already been termed a blight, it seems well to speak of it as the "late ; There is already another fungus called the " leaf-spot of celery. From later observations it seems that the late blight was the most injurious celery fun- IMf,'^'' gus during the past season, but v .^ it was not so destructive at ^^^^t^ Ithaca. Few experiments have as yet been made with the use of fungicides upon it, but it has been recommended by the New York (State) Station at Geneva to spray young plants with Bordeaux mixture. With older plmts it would be better to use the ammoniacal copper carbonate, or it may prove as well to use the latter throughout. The same caution relative to the use of healthy seedlings will apply as for the early blight, and in this case it is especially necessary to begin early. Further remedial suggestions will be made ^2.—SecHo7t of a pycnidium, or fruit- body^ of the late blight. Late Blight in the Storage House. It is to be remembered that the late blight may yet be active when thela«<- ''ot^ of celery is transferred to the coop, or root house, as these storage cellars are variously termed. This brings us to an important feature of the celery disease question, and one which, apparently, has hitherto received no attention. Again my atten- tion was first called to this matter on the premises of R. W. Parr, Ithaca, by an examination made late in December of celer}^ stored both in a cellar and in a root house.
