organic fertilisers, fulvic acid, Monilia fructigena, Monilia laxa, ultra violet light


Although organic fertilizers as a whole do not express any pesticide action in some cases, some of them
can prove a completely satisfactory level of pest protection, acting as fungicides or zoocides. Some of them even can
express induced system resistance effectiveness. In the present study, the effectiveness of four novels, organic
fertilizers created by Bulgarian company Agriflor on the base of fulvic acid and algal extracts was established in the
in vitro conditions towards conidiospores of Monilia fructigena and Monilia laxa – major plant pathogens on
orchard plants causing a lot of damages every year. The conducted trials reveal from the one side that all of tested
products can express a strong antifungal action towards the germination of the conidiospores and ultra violet light
can have a strong stimulation effect on the antifungal action of tested fertilizers from the other side.
