The protection of parsley seedlings (Petroselinum sativum Hoffm. ssp. microcarpum) against damping-off.
The experiment was carried out in the years 2003 and 2004 on parsley cultivar: 'Berlinska', 'Cukrowa', 'Vistula' and 'Kinga'. Mycological analysis of parsley seeds showed, that the most common inhabitans were fungi from genus Alternaria (mainly A. alternata and A. radicina) and Fusarium, especially F. avenaceum and F. oxysporum. The two-year study on the effectiveness of 5 substances--biopreparate Biochikol 020 PC (polymer of chitosol) and Biosept 33 SL (extract of grape-fruit); and fungicides: Amistar 250 SC (BAS azoxystrobin), Dithane M-45 80WP (mancozeb) and Zaprawa Funaben T (carbendazim+thiram) used against parsley damping-off was conducted in glasshouse and field conditions. Seeds of parsley were treated one of tested substances before sowing. The results of glasshouse experiments showed, that the best efficacy exibited Amistar and Zaprawa Funaben T for seedlings cultivar 'Berlińska' and 'Cukrowa' and Biochikol for 'Kinga'. During field experiments Zaprawa Funaben T showed the best efficacy for seedlings 'Berlińska' and 'Vistula'. Preparate Amistar was the best seed dressing for parsley cultivar 'Cukrowa' and 'Kinga'. During glasshouse experiments in control the highest number of decaying seedlings had cultivar 'Berlinska', in field experiments 'Kinga'.
