Abstract
Susceptibility of strawberry cultivars to the most common arthropod pests and diseases was evaluated over 1995-1997. High populations of twospotted spider mite were recorded on Elsanta, Kent, Marmolada and Dana, while cultivars Dukat, Kama, Senga Sengana, Syriusz, Real and Honeyoe were less infested.
A rapid expansion of strawberry mite has been observed on the plantations.
The most affected cultivars were Kama, Syriusz and Gerida.
Low numbers of this mite were recorded on Redgauntlet, Dukat, Marmolada and Senga Sengana cvs.
The lowest and the highest percentage of flower buds damaged by strawberry blossom weevil were noted on the medium-early ripening ‘Dana’ and early ripening ‘Kama’, respectively.
Damages to flower buds due to strawberry blossom weevil were below the economic threshold for all cultivars tested.
Mirid bugs damaged mostly the fruits of ‘Kama’, while cvs Cortina, Dana, Elsanta, Gerida, Kent and Senga Sengana suffered the lowest losses due to this pest.
The highest level of grey mould fruit infections was observed on cvs Senga Sengana, Syriusz, Marmolada and Dana.
Some cultivars, like Kent and Honeyoe, were only slightly affected.
Severe leaf spot symptoms were noted on cvs Kama, Kent, Real and Syriusz, while Dukat, Dana, Honeyoe and Marmolada showed high levels of resistance.
The cultivars most susceptible to powdery mildew were Gerida, Elsanta and Marmolada.
Some cultivars like Cortina, Dana, Kama and Kent were almost resistant.
Verticillium wilt severely damaged strawberries of Elsanta, Gerida, Kent and Syriusz cvs while Senga Sengana, Dukat, Kama and Real were resistant.
Crown rot (Phytophthora cactorum), a new disease in Poland, has been found only on two cvs, Elsanta and Honeyoe.
