ABSTRACT
Disease management during plant propagation is critically important to ensure a disease-free plant for the consumer. In most production systems, there is no other time that so many immature plants are exposed to conditions so favorable for disease development. Seedlings or cuttings are grown essentially in monoculture in ats or beds that can account for the rapid spread of disease. Vegetatively produced cuttings are often grown under conditions of high relative humidity that favor several foliar diseases. Also, in many parts of the world, coolseason annual bedding plants are predisposed to some root rot diseases by exposure to high temperature. Anyone involved in plant production needs to realize that producing a healthy, saleable plant starts prior to and continues during plant propagation. At this point of plant production, you are most likely to lay the foundation for the health of the crop.
