Abstract

A greenhouse experiment was performed to determine the effects of the fungicides containing cyprodinil as well as dimoxystrobin and epoxiconazole on the activity of soil enzymes: dehydrogenases, urease, acid phosphatase and alkaline phosphatase, depending on fungicide dose (0 - control, 1 - recommended dose, 10-fold dose and 100-fold dose), the method of soil management (soil cropped with spring barley cv. Start, and uncropped soil) and the time of fungicide action (14, 28, 42 and 56 days). The experiment was established on Eutric Cambisols with pHKCl = 6.7. It was found that the enzymatic activity of the soil was affected primarily by such factors as fungicide dose, method of soil management and time of fungicide action, and to a much lesser degree by the type of fungicide. Fungicide contamination of the soil significantly inhibited the activity of dehydrogenases and urease, and produced a significant negative effect (100-fold dose) on spring barley yield. A higher activity of dehydrogenases, urease, acid phosphatase and alkaline phosphatase was recorded in the soil cropped with spring barley cv. Start.
