Testing of varieties, mulch materials and biofungicides Supresivit (Trichoderma harzianum Rifai aggr.) and Polyversum (Pythium oligandrum Drechs.) in organic strawberries

Original language description

In 2008--2009 experimental plots with organically grown strawberries cv. Elsanta, Honeoye and Symphony were conducted in Southern Moravia in the Czech Republic. The effect of two mulch materials (wheat straw, PE plastic) and two biofungicides (Supresivit-- Trichoderma harzianum Rifai aggr., Polyversum -- Pythium oligandrum Drechs.) on yield and health condition were assessed. Elsanta reached the best yields, Symphony proved high resistance to root rots. Honeoye showed remarkable resistance to grey mould but it was quite susceptible to root rots as well as Elsanta. Biofungicides decreased the number of necrotic plants due to root rot complex and decreased the number of berries infected by grey mould, nevertheless the differences were not statisticallysignificant from untreated control. Application of Supresivit resulted in the highest marketable yields. Straw mulch significantly decreased the number of necrotic plants, but it increased grey mould occurrence on fruits.
