Abstract
Ecological vegetable cultivation uses organic preparations for protection and nutrition of plant. Tomato is one of the most important grown vegetables in our area. For this study tomatoes were planted on the open, development of Phytophthora infestans was monitored and the effect of vermicompost tea on the inten- sity of disease, number and mass of fruit was determined. The treatments were: treatment of tomato with vermicompost tea by applying water to the soil (Vz), by applying water to the soil and spraying the overground part of the plant (Vz + Vp), treatment with fungicide Penncozeb 75 DG (F) and control (K) without application of vermicompost tea or fungicide. Late blight infection had a lower intensity, and the disease index ranged from 0.04 (Vz + Vp) to 0.08 (K). The highest average number of fruits was determined in Vz + Vp treatment, while statistically lowest average number of fruits was determined in control treatment. Treatment Vz + Vp showed statistically the best effect on the mass of fruits, followed by treatments Vz and F, which confirms the positive influence of vermicompost tea compared to untreated tomato.
