Evaluation of fungicides for Nordic golf courses
Summary
This project includes fungicide trials under the industrial partnership agreement between STERF and Syngenta. Information about new fungicides that have not yet reached the market is proprietary to Syngenta, but information about the optimal use and comparisons of products that are or have been on the market is published and presented by STERF researchers.
From October 2014 to May 2015 three new green trials and four new fairway trials were carried out according to two different protocols at NIBIO Apelsvoll and Arendal GC in Norway, Loimijoki GC in Finland and Österåker GC in Sweden. Major conclusions for Syngenta’s fungicides Banner Maxx (propiconazole; registered in Sweden) and Medallion (fludixonil; registered in Finland, Sweden and Norway) were:
• One application of the Banner Maxx in mid-October reduced microdochium patch in spring by on average 80% compared with the unsprayed control
• Subsequent applications of Medallion increased the control level, but it was more efficient against M. nivale if applied three instead of six weeks after Banner Maxx. Medallion was also better at enhancing spring green-up if applied no more than three weeks after Banner Maxx
• Four applications of Medallion as the only fungicide from Oct. to 1 Dec. provided complete control of turfgrass winter diseases and improved the visual quality in spring from 6.3 to 7.3 on a scale from 1-9. Despite this, we recommend use of Medallion after a systemic fungicide, as the repeated use of only one fungicide type may create a risk of fungicide resistance.
Three new green trials (NIBIO Landvik and Toten GC in Norway and Lepaa GC in Finland) and two new fairway trials (Toten and Lepaa) were started in October 2015.
