DOI:https://doi.org/10.53040/ppap2023.32.For the purpose of sunflower's protection from white mold (pathogen Sclerotinia sclerotiorum), it was tested biologic preparate Sclerotsyd®. The fungicide was used by spraying the working suspension with subsequent incorporation into the soil. Were used three application rates: 1) Sclerotsyd® - 0.5 l/ha, 2) Sclerotsyd® - 1.0 l/ha, 3) Sclerotsyd ® - 2.0 l/ha, control – without applying any products. The purpose of the research is to test the consumption rates and determine the biological effectiveness of the biological product in the control of sunflower’s root and head white mold. As a result, it was established that the most effective use rate of the biopreparation Sclerotsyd® for suppressing the development of sunflower’s mold and white head mold it is recommended the rate of 2.0 l/ha with a biological efficiency of 86.2-87.0%.roSclerotsydconsumption ratewhite moldbiological efficiencyArticle
