In the year 2008, 166 apple, bean, carrot, cucumber, lettuce, pear, potato and spinach samples from Slovene producers were analysed for plant protection product residues. The samples were analysed for the presence of 158 different active compounds using three analytical methods. In two samples (1.2%) exceeded maximum residue levels (MRLs) were determined. The most frequently found active substance in agricultural products was dithiocarbamates. Products which contained 4 or more active substances per sample were apples and pears.

COBISS.SI-ID: 3748712Sooty blotch and fly speck (SBFS) fungi colonize apple fruits but are not known to be plant pathogenic or fruit destructive. Because various taxa can grow in media with artificial or biological wax substrata as sole carbon source, they seem to be well adapted to the waxy layers of the plant cuticle. Colonies of different SBFS species can be sharply demarcated from each other on the fruit surfaces. Their slow growing colonies can inhibit fast growing plant pathogens like Colletotrichum spp. in dual culture tests. Preliminary tests have shown that extracts of secondary metabolites from SBFS cultures can inhibit the germination of spores of plant pathogenic fungi. It is hypothesized that SBFS fungi can be exploited as biological control agents that could interfere early with air disseminated spores of pathogens targeting plant cuticles. The research on this theme is done by the young researcher A. Medjedović.
