Abstract
Summary American gooseberry mildew (Podosphaera mors-uvae), leaf spot (Drepanopeziza ribis) and white pine blister rust (Cronartium ribicola) are the most severe fungal diseases of black currant (Ribes nigrum). On commercial plantations control of these diseases is based mainly on the chemical method. However, the assortment of currently registered fungicides is limited to three products. The experiments, performed in 2010–2011 with new fungicide Luna Sensation 500 SC containing fluopyram and trifloxystrobin, showed its high effectiveness in control of black currant diseases. This fungicide applied at the doses of 0.6 and 0.8 l/ha very effectively controlled American gooseberry mildew (over 96%), leaf spot (over 88%) and white pine blister rust (over 82%). The effectiveness of Luna Sensation 500 SC was similar or higher than commonly used fungicides such as Score 250 EC and Signum 33 WG, thus it can be a suitable candidate recommended for efficient control of black currant fungal diseases, especially for anti resistant strategy.

Summary
Fungicyd Luna Sensation 500 SC stosowany zarówno w dawce 0,6, jak i 0,8 l/ha zwalczał amerykańskiego mączniaka agrestu w ponad 96%, antraknozę liści porzeczki w ponad 88%, a rdzę wejmutkowoporzeczkową w ponad 82%. Skuteczność fungicydu Luna Sensation 500 SC była podobna do powszechnie stosowanych fungicydów Score 250 EC i Signum 33 WG lub wyższa. Celem pracy była ocena skuteczności działania fungicydu Luna Sensation 500 SC w zwalczaniu amerykańskiego mączniaka agrestu, antraknozy liści porzeczki i rdzy wejmutkowo-porzeczkowej na plantacjach porzeczki czarnej.
