Key Points
- The yield response of fescue to Moddus varied between cultivars with a greater yield response in Advance compared with Vulcan
- The yield of Advance increased with an increase in Moddus rate (560 to 1420kg/ha)
- The yield of Vulcan also increased as the rate increased but the yield increase was only 200kg/ha and there was no difference between the different rates of Moddus
- Timing of application was important with yields 18% higher from the GS32 application in Advance than a GS39 application
- Adding Opus increased seed yield at 400mls but not at 800mls/ha. Adding ammonium sulphate did not impact on seed yield
- Increasing the rate of Moddus both delayed and reduced lodging. Adding ammonium sulphate enhanced activity in reducing lodging
- Overseas, Apogee has performed well as a PGR in fescue
