The external appearance and quality of table potatoes are determined, among other factors, by the health status of the plants during the growing season. Chemical control methods are often combined with biocontrol agents to effectively fight potato pathogens. Potatoes of the very early cultivar Rosara were grown in experimental plots. The plots were located in Tomaszkowo (NE Poland, 2007–2009). The experiment involved the following treatments: 1) biological control − mycorrhizal Glomus spp. inoculum was applied to the roots, − tubers were dressed and plants were sprayed with Polyversum three times during the growing season, 2) chemical control – at two-week intervals, plants were sprayed with the following fungicides: Infinito 687.5 SC and Tanos 50 WG, Valbon 72 WG and Tanos 50 WG. In the control treatment, potato plants were not protected against pathogens. During the growing season, the severity of late blight and early blight was evaluated on a nine-point scale. The composition of fungal communities colonising potato stems was analysed. The fungistatic properties of the fungicides used in the field experiment were evaluated in an in vitro test. The symptoms of infections caused by Phytophthora infestans and Alternaria spp. were significantly reduced in the treatment which used the integrated chemical and biological control. The least diverse fungal community was isolated from fungicide-treated plants. In the in vitro test, fungicides at all analysed concentrations inhibited the linear mycelial growth of selected pathogens.

W pracy zbadano plonowanie roślin czterech bardzo wczesnych odmian ziemniaka w zależności od wielkości zastosowanej dawki promieniowania mikrofalowego. Czynnikami doświadczenia były: odmiana ziemniaka (Felka Bona, Rosara, Velox i Lord), czas napromieniowania mikrofalami (5, 10 i 15 s) oraz moc generatora mikrofal (100, 200 i 300 W). Dawka promieniowania, moce generatora oraz czas napromieniania sadzeniaka mikrofalami istotnie modyfikowały plon bulw ziemniaka spod jednej rośliny. Napromienianie sadzeniaków mikrofalami pochodzącymi z generatora działającego z mocą 100 W przez czas 5-15 s powodowało, w odniesieniu do próby kontrolnej, zwiększenie plonu bulw ziemniaka spod jednej rośliny potomnej.
