CARROT Soft rot, bacillose (Bacillus carotovorus Jones ^).— In Ver- mont serious loss from rotting of carrots was reported to the Experiment Station in 1898. Investigation by Jones* showed it to be due to bacteria and that numerous other crops, namely, turnip, rutabaga, radish, salsify, parsnip, onion, celery, hyacinth leaves, and the fruit of tomato, eggplant, and pepper were susceptible to the same disease. Cauliflower, Irish potato, sweet potato, beet, and asparagus were not susceptible. ' Grossenbaeher, J. G., (Geneva) Agr. Exp. Sta. Tech. Bui. 9, Febraary, 1909. ; 2 Jone3, L. R., Vt. Agr. Exp. Rpt.
