Cultural Control and Sanitary Measures
Sanitation is also effective for disease control. For example, disinfecting machetes and pruning tools between plants may help control the disease in Platanus (Walter, 1946; Walter et al., 1952) and Prunus (Teviotdale and Harper, 1991). Heat treatment of Ipomoea roots used in propagation has been suggested (Daines et al., 1962).
