Chemical control of Phytophthora oleae and its potential for disease management in olive orchards and natural forests
2020
González, Mário | Sánchez, María-Esperanza
The new species Phytophthora oleae is a pathogen recently reported causing fruit rot on olive orchards in Italy and root rot in a natural wild-olive forest in Spain. Potassium phosphite, fosetyl-Aluminium and metalaxyl were evaluated in pot experiments for root disease control. All the three systemic products led to a significant decrease of root necrosis caused by olive Phytophthora pathogens (P. cryptogea, P. megasperma and P. oleae) when applied at recommended doses to inoculated seedlings, even though fosetyl-Aluminium did not significantly inhibit mycelial growth in vitro. The tested products have potential to protect commercially planted olive orchards from these Phytophthora pathogens, including the new species P. oleae in natural woodlands that, in turn, put at risk cultivated olive orchards.
