- Abstract
Bull's eye rot, caused by Neofabraea spp. is one of the most important fungal diseases of storage apple in Poland. The effectiveness of fungicides: Bellis 38 WG (boscalid, pyraclostrobin) and Switch 62,5 WG (cyprodinil, fludioxonil) in protection against bull's eye rot of cultivar Shampion apples during storage and their residues in apples were investigated. The experiments were conducted in 2012-2014. T he f ungicides w ere a pplied a s a s ingle, t wo and three applications before harvest. After 6 months of storage the biological effectiveness of the fungicides was assessed. The highest effectiveness was obtained after three applications of the tested fungicides; for Switch 62,5 WG - 96.4% in the season 2012/2013 and 92.7% in the season 2013/2014, and for Bellis 38 WG - 84.7 and 91.0%, respectively. The results of analyses of boscalid, pyraclostrobin, cyprodinil and fludioxonil residues showed that apples contained residues that exceeded 0.01 mg/kg but below European Union Maximum Residue Levels.
