Description
  • In 2011 and 2012 three commercial products Alginure (seaweed extract), Myco-SinVIN (sulfuric acid clay with yeast and plant extracts) and Polyversum (spores of Pythium oligandrum) were tested in field experiment with strawberry cv. 'Induka' under the conditions of organic growing system. The aim of the study was to determine the effect of the preparations on yield, fruit quality and diseases control. The preparations were applied five times during flowering. We assessed total yield, marketable and unmarketable yields, average fruit weight, grey mould incidence on fruits caused by Botrytis cinerea and leaf spot severity caused by Mycosphaerella fragariae. Efficacy (%) of preparations was calculated. Preparations did not show positive effect on yields parameters. Total and marketable yields were not significantly different to untreated control in both years. Nevertheless considerable increase of yields from 2011 to 2012 was observed in strawberries treated by biofungicide Polyversum. Preparations did not significantly reduce the incidence of grey mould. Alginure showed the best results by efficacy 39.6 % and 57.4 %, respectively. All preparations provided very low, less than 10% efficacy to control leaf spot severity.
