Sažetak
During April 2011. collected 96 samples of olive leaves, from 74 locations in six counties to establish latent infection of olive leaves with fungus Spilocaea oleagina (Castagna) Hughes. The latent infection is detected using the leaves soaked in 5% sodium hydroxide. There were sampled with the most common variety Oblica and other varieties - Istarska bjelica, Bu2a, Carbonaca, Krvavica, Drobnica, Lastovka, Starovjerka, Plominka, Simjaca, Drobnica and Paka. The results showed differences in susceptibility of cultivars and even within the same locality. Fixed percentages of infection ranged from 0% at all locations up to 100% infection. Of the total number of sampled locations, only twelve of them had percentage of infection lower than 10% which is the threshold tolerance Spilocaea oleagina (Castagne) Hughes fungus infection. The research results indicate that the majority of olive growers are not implemented to date protection against pathogens of Peacock olive leaf spot. The results show the prognostic significance of conducting activities related to monitoring the disease and the need to provide regular forecasts on the protection of olive trees against this disease.
