RMF1FHK6–Infection experiments with Septoria petroselini var. apii causing late blight of celery (1915)
RMRH116P–. Bulletin. Agriculture -- Ontario. 14 recommended to use the Ammonicial-copper carbonate solution in the latei sprayings. Leaf Spot (Septoria petroselini, var apii): Brown spots, studded with minute black spots, appear on the leaves.. Celery Blight. (Cercospora />ii.)—A, spores through the agency of which the disease spreads ; B, tuft of aerial protruding through a breathing-pore of a leaf ; C, a diseased leaf, showing the brown. Remedies : Same as for leaf blight above. i i Corn. (Insects). Corn-Stalk Borer (Papaipema nitela) : The larvae which belong to the Cutworms bore into the stalks
