Train the plants so as to secure a free cir- culation of air among them. Geneva Bulletin 100. CELERY. This is sometimes known as "early Cerospora, ; It often appears in the seed- leaf-blight, bed and becomes destructive early in the summer. It is favored by hot weather, either wet or dry. Spray with ammoniacal copper carbonate, 6-3-45, making about five or eight applications and beginning while the plants are still in the seed-bed. Bordeaux, 5-5-50, may be used for the earlier application. Spray often enough to keep new growths of leaves covered. Destroy diseased plants and refuse. Cornell Bulletin 132. Leaf blight is a fungous disease Septoria, leaf- appearing late in the season. It is blight or often destructive after celery is "late ; stored. The same treatment as for "early blight" is used except that spraying should be continued up to the time the plants are harvested. (Cornell Bulletin 132.) Well drained celery fields, half-shaded, do not seem to suffer from either blight. ^^: Black-knot.
