Protection of basilium (Ocimium basilicum L.) seedlings against fungal diseases

摘要

In our investigations on protection of basilium seedlings were used the following preparations: Chiosol, Biosept, Bioczos BR, Polyversum and as the standard fungicide Amistar 250 EC. All tested preparations were used at three concentrations. The obtained results showed, that all used preparations protected against infestation by tested fungi. Efficiency was differentiated in dependence on basilium seedlings fungal species, experimental conditions, used preparation and its concentration. In a climatic chamber the best protective activity showed Polyversum against Sclerotinia sclerotiorum in all used concentrations. However in protection of basilium seedlings growing in glasshouse conditions Polyversum had a weaker protective activity in each experimental treatment. In this case Amistar at concentration 0.025% showed the best activity. In the remaining experimental treatments, in glasshouse, preparations showed a weaker activity than the standard fungicide, but their protective activity was significant in comparison to the control..
