Integrated control strategies of olive tree diseases.
This paper reports the integrated control strategies of the main olive tree diseases, focusing attention on recent advances of research and also gives a concise description of symptomatology. Preventive agronomic and chemical measures are considered the effective strategies for controlling olive scab (Spilocaea oleagina), cercosporiosis (Mycocentrospora cladosporioides), Verticillium wilt (Verticillium dahliae), and knot disease (Pseudomonas savastanoi pv. savastanoi) in olive orchards. The use of tolerant or resistant cultivars to fungal and bacterial diseases and also sanitary selection and sanitation (heat therapy, meristem tip culture) of plant propagation materials against viruses and phytoplasmas are recommended as the best control strategies in new orchards and nurseries.
