Sanitation Can Be a Foundation Disease Management Tool: Potential of Spreading Binucleate Rhizoctonia from Nursery Propagation Floors to Trays Containing Azalea Stem Cuttings

摘要

Many people see sanitation as simple control techniques with limited application. However, a technical definition of sanitation is any control action that lowers the initial pathogen level so that the amount of final crop loss is reduced or a damagingthreshold of disease is delayed. The resulting reduction in disease, whether from a single control action or integrated disease management, can be dramatic and desirable (Daughtrey and Benson, 2005; Jones et al.， 2001; Williams-Woodward and Jones, 2001). Ultimately, pathogen reduction is a desirable goal that reduces the need for other controls or magnifies their effectiveness. The potential for pathogen reduction (sanitation) to be beneficial is greater in ornamental plant production than any other commodity system, yet this potential has not been imaginatively explored using current research concepts.
