Abstract
Phytophthora and its devastating damage to various agricultural, horticultural and forestry species is a never-ending saga. However, a recent survey in Sardinia, Italy has made headlines as a widespread dieback and decline of wild olives across 200 ha area. The two yearlong studies focused on the identification of causal agents and mapping the diseased area. Isolation of multiple Phytophthora species from such a small area has astonished researchers with P. pseudocryptogea and P. bilorbang being the two most frequent. However, the involvement of phytophthora in olives is not new and possesses a great historical significance worldwide. Infection on wild olives, which serve as rootstock for commercial olives, has the potential to bring down the overall olive production. Thus, to save the olive cultivators and this valuable component of agroforestry landscape, further research on the pathogen with advanced disease monitoring and management practices are waiting to be ventured more intensely.
