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%.
