EFFECTIVENESS OF BIOFUNGICIDES BIOCZOS S AND POLYVERSUM USED TO SOAK STRAWBERRY CUTTINGS IN VERTICILLIUM WILT DISEASE CONTROL

摘要

The objective of the work was to assess the effectiveness of biofungicides Bioczos S and Polyversum applied by soaking cuttings prior to planting to control Verticillium wilt in strawberry. Studies included two strawberry cultivars (Honeoye and Elvira) with different resistance to Verticillium wilt. An experiment was established in a Verticillium wilt infected field.Strawberry cv. Elvira was more resistant to Verticillium wilt than Honeoye. It was found that the preparations applied in the experiment did not provide sufficient protection of both strawberry cultivars tested against Verticillium wilt. For Honeoye all the fungicides, in particular Previcur 607 SL and Bioczos S supplemented with humic acids, assured better survival of mother plants compared with the control. This cultivar was also characterized by higher yields obtained following application of fungicide Previcur 607 SL. No impact of either preparation on the number of runner plants was found.
