To receive agar medium containing 30 mg/l of the test compound. To the medium control was added with pure acetone in the same amount. So prepared medium was poured into Petri dishes, cooled and the surface of the hardened agar were sown pieces of fungal mycelium, after which the cups were incubated for 3 days at 25±0,5°C. Inhibition of mycelium growth was calculated in percentage of the untreated control. As a reference used commercial fungicide triadimefon in the same concentration.
