| Nowadays, organically produced products have become more popular than ever and interest in them is still growing fast. The early blight causal pathogen Alternaria solani has not been considered a great threat to potato in northern climate conditions in the past and has not been routinely sprayed against. During our study early blight was evaluated in 2010 and 2011 on the plants of a potato cultivar ‘Reet’ in an organic farming experiment. In our study, both growing seasons were very favourable for early blight development. Significant differences between the two cultivation technologies were found (F1,12 = 4.84, p = 0.048). In 2010, the area under disease progress curve (AUDPC) value was 303 on cover crop (CC) plots and 990 on CC + M (manure)... |

| Two locally available and well-known plants, such as common tansy Tanacetum vulgare L. and wormwood Artemisia absinthum L. were tested for insecticidal activity. They were found to produce a variety of effects against the white large cabbage butterfly Pieris brassicae l., the Colorado potato beetle Leptinotarsa decemlineata Say and the greenhouse whitefly Trialeurodes vaporariorum Westw. These plants affected the feeding activity, behavioural pat-terns, the development and induces mortality in the insects. |
