 Among the olive cultivars used for pollination are the Cayon, Picholine, Verdale and Arbequina.A major drawback with this cultivar is its vulnerability to certain biological pests, such as the "Bactrocera oleae", "Pseudomonas syringae", "Saissetia oleae", and Sooty moulds.On the other hand, it has an exceptional resistance to cold; after the devastatingly hard winter of 1956, when most French olive orchards were destroyed, many Olivière trees survived.
