Experiences in controlling fire blight (Erwinia amylovora) in Croatia

In Croatia Fire Blight was observed for the first time in 1995 in the village of Nuštar not far from the Yugoslav border. Soon after we found several other foci. After these discoveries the Osječko-baranjska and Vukovarsko-srijemska counties were proclaimed quarantine areas. In accordance with legal regulations all quarantine measures were undertaken. The trees began to be eradicted. Until 1998 the Ministry of agriculture and forestry paid (covered the expenses) for each eradicted tree so that until that time we have an exact picture of eradicted trees. Until that time 199 432 apple trees, 142 479 pear trees, 148 quince trees and 152 medlar trees were eradicted and burned. Despite the measured undertaken in 1998 individual infections were found in the Požega valley, in the region of Slavonski Brod, Virovitica and so these areas were also proclaimed quarantine areas. Soon afteer we had identified E. amylovora it became clear that we would have to learn how to grow pomme fruit in its presence. Therefore we tested the efficacy of some bactericides, namely: Flumequine (Firestop), streptomycin sulphate, copper hydroxide (Champ F2), and fosetil-aluminium (Aliette). Among the tested bactericides Firestop proved the most efficient folloved in descending order by Champ F2 and streptomycin sulphate. Even before apperance of Fire Blight in Croatia in 1993 on the basis of climatological indicators according to Billing`s method we determined the areas that were risky regarding the apperance of this disease. In 1997 the forecasting programme MARYBLIGHT 4, 3 wes acquired and should be used in areas in which Fire Blight is present. This year we set up a pilot orchard in Osijek with less sensitive apple cultivars in order to be able to recommend in the future certain less sensitive varietes with good economical features.
