Effect of forecrops on soil environment and the plant in relation to the health of the strawberry

This research presents an evaluation of the effect of forecrops (after papilionaceous, root and cereal plants) on the health of the strawberry of the Senga Sengana variety. The diagnostics of diseases were carried out on the basis of symptoms occurring on those parts of the plant above the ground, as well as on the roots, and additionally on the basis of mycological analysis. The results obtained indicate that the main cause of the strawberry dying back and the occurrence of disease symptoms were the species of Fusarium genus after root plant fore crops; Fusarium spp.. Alternaria spp., Botrytis spp., Cylidnrocarpon spp., Phoma spp., Rhizoctonia spp., and Verticillum spp. after papilionaceous plant forecrops and Fusarium spp., Alternaria spp., Pythium spp., Rhizoctonia spp. after cereals.
