This disease is readily distinguished by the presence of brown or black veins in leaves and cross sections of leaf stalks and plant stems. Badly affected plants are stunted and many of the lower leaves may drop off. The disease originates from the presence of a parasitic bacte- rium either on the seed or in the soil. All danger of disease from seed is removed by soaking for fif- teen minutes in a solution of cor- rosive sublimate, one ounce
. The vegetable industry in New York state ... Vegetables; Gardening. Diseases op Vegetables 1327 CABBAGE Black Rot (Pseudomonas Cam- pestris Erw. Smith). This disease is readily distinguished by the presence of brown or black veins in leaves and cross sections of leaf stalks and plant stems. Badly affected plants are stunted and many of the lower leaves may drop off. The disease originates from the presence of a parasitic bacte- rium either on the seed or in the soil. All danger of disease from seed is removed by soaking for fif- teen minutes in a solution of cor- rosive sublimate, one ounce dis- solved in seven gallons of water, or in formaldehyde, one pint to thirty gallons of water. Susceptible crops should not be grown on soil where the disease has occurred until a few years have elapsed. Cauliflower, rape, kale, turnips, wild miistard and other cruciferous plants are also susceptible. Club Root (Plasmodiophora hrassicae Wor.), Fig. 385. Un- sightly swellings occur on the roots of cabbage, cauliflower, tur- nips, radishes, shepards purse, wild mustard and other re- lated plants. The causal parasite lives in the soil. It is best controlled by rotating crops so that a susceptible crop is grown on a given field only every fourth to seventh year, but in the meantime the field must be kept free from weeds on account of the susceptibility of many weeds. If infested soil must be used apply lime at the rate of three to five tons per acre. Apply and harrow into the soil the fall before planting, or better, a year or two Fig. 384.— Bean Blight.
