. The vegetable industry in New York state ... Vegetables; Gardening. DISEASES OF VEGETABLES Peofessoe J. C. Jaggee Assistant Professor of Plant Pathology, University of Rochester, Rochester, X. Y. CAUSES OF DISEASES Diseases of plants result from several causes. Unsuitable soil and weather or improper cultural methods are often the cause of unhealthy plants. Insects are more or less injurious to all crops. Many diseases result from the growth within af- fected plants of minute parasitic plants known as fungi and bacteria. Other dis- eases, which appear to be of importance in Xew York State to the growers of the vegetables treated in this bulletin, are briefly discussed. JIETHODS OF CONTEOL Vegetables can not be cured of disease as can men and animals. They must be protected from the attack. The method of control to be employed for a given disease is determined by its cause and by the nature of the crop attacked. Evidently diseases resulting from conditions of soil, weather or culture can be avoided by making conditions suitable or by growing crops, varieties or strains of plants which are not injured by the conditions. Control meas- ures to be employed against the many diseases resulting from the attacks of parasitic fungi and bacteria depend primarily on the nature and habits of the parasite. Crop Rotation, llany parasites live from year to year in the soil and will die out and disappear if crops are so rotated that susceptible crops are not grown in an infested field for a few years. Soil Sterilization. Several diseases, resulting from parasitic organisms which gain entrance to the plants from the soil, are very effectively controlled by soil sterilization.
