Descrição: In an Integrated Pest Management system it is very important to follow all scientifically recognized measures in order to limit plant disease problems. In this research we focused on the importance of variety choice to decrease potato tuber diseases in integrated or biological growing systems. Data of 75 potato varieties grown under similar Latvian agroclimatic and soil conditions were used. Potato tubers were not treated with fungicides. The selected tolerant 20 potato varieties were evaluated against common scab Streptomyces scabies Guss, black scab Rhizoctonia solanacearum Kühn, powdery scab Spongospora subterranea f.sp. subterranea Lag, and silver scurf Helminthosporium solani Durieu and Mont, as well as whether they are appropriate for use in an integrated plant cultivation system or organic farming. Statistical analysis was done by MS Excel data analysis tool ''Correlation''. Diagnostics of tuber diseases was done by visual testing and the Bioreba and Adgen Ltd Neogen test kits. Only 23% of the varieties had healthy tubers that had not suffered from damage of wireworms (Agriotes spp.). Experimental data showed the phenomenon that under identical agroclimatic and soil conditions, some varieties were more attractive for wireworm damages than others. A relationship was established between wireworm damages and the spread of black scab (r=0.594).
