The late blight of celery is a comparativelyrecent disease in the United States, and in Europe it has not beenconsidered a serious celery malady. It is most injurious as a ruleduring the early autumn, although a few spots of this disease maybe seen at any time during the summer where it is at all spots are irregular in outline and of a rusty brown color.
