Abstract
The efficiency of 7 different fungicides, recommended controlling early blight, in reducing the mycelial growth of Alternaria spp. was evaluated in laboratory experiments using potato-agar medium. Three contact fungicides: zoxamide + mancozeb (Unikat 75 WG), fluazynam (Altima 500 SC) and propineb (Antracol 70 WG), two translaminar fungicides: cymoxanil + famoxate (Tanos 50 WG) and fenamidon + mancozeb (Pyton 60 WG), and two systemic fungicides: metalaxyl-M + mancozeb (Ridomil Gold MZ 68 WG), and iprowalikarb + mancozeb (Melody Med 69 WG) were compared. The results showed that all the tested fungicides significantly reduced the mycelial growth. The lowest effectiveness was observed with the mixture cymoxanil + famoxate (Tanos 50 WG).
