| Abstract:
Susceptibility to diseases of strawberry cultivars and selections was evaluated in field trials during four years (1999-2002). Some cultivars like ‘Honeoye’, ‘Polka’, ‘Karel’, ‘Selva’, ‘Elkat’ and ‘Elsanta’ showed a very high or high level of tolerance to Botrytis cinerea infections. The wide range of reaction to leaf spot and powdery mildew was observed among tested cultivars and selections. ‘Dukat’, ‘Marmolada’, ‘Tenira’, ‘Selva’, ‘Elkat’ and ‘selection 1476’ were the most resistant for leaf spot. Only slight powdery mildew symptoms were recorded on ‘Dukat’, ‘Real’, ‘Syriusz’, ‘Florence’ and no symptoms developed on ‘Filon’, ‘Jossee’, ‘Onda’, ‘Kent’ and ‘Dana’. In the last years, on some strawberry plantations, a serious losses are caused by verticillium wilt. Many of cultivars, commonly planted for fresh market, are very susceptible. A high resistance for this disease showed ‘Dukat’, ‘Kama’, ‘Melody’, ‘Real’, ‘Senga Sengana’, ‘Seal’, ‘Jossee’, ‘Filon’ and 13 selections. Crown rot is also rather new problem in Polish strawberry production. Until now severe symptoms of crown rot were observed on fruiting plantations of two cultivars, ‘Elsanta’ and ‘Honeoye’. Disease was also noted on some stock plantations. No symptoms were recorded on ‘Dukat’ and ‘Senga Sengana’ cultivars. The high number of ‘Polka’, ‘Dukat’ and ‘Senga Sengana’ fruits showed leather rot symptoms while only some fruits of ‘Selva’, ‘Pegasus’ and ‘Elkat’ were affected. High population of two-spotted spider mite - Tetranychus urticae was recorded on ‘Elkat’, ‘Elsanta’, ‘Honeyoe’, ‘Kent’, ‘Pegasus’, ‘Seal’, ‘selection 1248’, ‘Selva’ and ‘Tenira’, while cultivars ‘Karel’, ‘Kaster’, ‘Polka’ and ‘selection 723’ were less infested. The strawberry mite - Phytonemus pallidus ssp. fragariae was mostly noticed on cvs: ‘Elkat’, ‘Elsanta’, ‘Honeyoe’, ‘Kaster’, ‘Kent’, ‘Marmolada’, ‘Polka’ and ‘Selva’. The lowest number of this pest was recorded on cultivars: ‘Pegasus’, ‘selection 723’ and ‘Vega’. The highest percentage of flower buds being damaged by strawberry blossom weevil - Anthonomus rubi was noted on: ‘Elkat’, ‘Honeyoe’, ‘Kaster’, ‘Kent’, ‘Polka’, ‘Seal’, ‘selection 1476’ and ‘Tenira’, while the lowest on cvs: ‘Evita’, ‘Karel’, ‘Malling Pandora’, ‘Marmolada’, ‘Selva’ and ‘Tarda Vicoda’. European tarnished plant bug - Lygus rugulipennis damaged mostly fruits of ‘Elkat’, ‘Evita’, ‘Honeyoe’, ‘Kent’, ‘Marmolada’, ‘Selva’ and ‘Tarda Vicoda’, while cvs ‘Malling Pandora’, ‘Pegasus’ and ‘Senga Sengana’ suffered the least of all. | |
