Survey of Spilocaea oleagina, causal agent of olive leaf spot, in North of Iran

S. J. Sanei and S. E. Razavi | View Article Olive leaf spot or peacock spot, caused by the fungal pathogen Spilocaea oleagina, can cause reduced growth and yield in olive trees (Olea eurapaea). Investigations were carried out during 2007-2010 to measure the prevalence and severity of olive leaf spot in the northern olive growing regions of Iran. The susceptibility of ten cultivars (Amygdalifolia, Blaidy, Koronakei, Mary, Manzanillo, Mission, Rooghany, Valatolina, Wild olive, Zard) to the disease was assessed. Olive scab was found in all study areas and with the worst affected in high relative humidity (Y= -21.058 + 0.794X,...

Effect of climate on olives

Vera Sergeeva | View Article Climate change has the potential to significantly impact Australia’s agricultural production. The predicted results of climate change Рincreased temperature, moisture and CO2 Рcan impact all three elements of the plant disease triangle (host, pathogen and environment) in various ways. Changes in temperature, rainfall, and extreme events will affect water availability, soil quality, fire risk, and the incidence of known and new diseases, pests, weeds, and disorders. Decreased soil and air moisture increases the incidence and impact of frost, while the frequency and severity of floods and drought are also expected to...
