The aim of the field experiments carried out in 2011–2013 was to evaluate the usefulness of fungicides, natural products and a growth stimulator used in integrated protection against Alternaria leaf spot of Chinese cabbage (Alternaria spp.). The following products were evaluated: two fungicides – Amistar 250 SC and Signum 33 WG, the natural products – Timorex Gold 24 EC and a strawberry extract and a growth stimulator Huwa-San TR 50. The examined products showed high effectiveness in protection of Chinese cabbage against Alternaria leaf spot.

Celem przeprowadzonych w latach 2011–2013 badań polowych było określenie przydatności fungicydów, środków naturalnych i stymulatora wzrostu w integrowanej ochronie kapusty pekińskiej przed czernią krzyżowych (Alternaria spp.). Przedmiotem badań były następujące środki: dwa fungicydy – Amistar 250 SC i Signum 33 WG, środki pochodzenia naturalnego – Timorex Gold 24 EC i ekstrakt z truskawek oraz stymulator wzrostu Huwa-San TR 50. Badane środki wykazały wysoką efektywność w integrowanej ochronie kapusty pekińskiej przed czernią krzyżowych.
