Stop and Prevent Winter Fusarium

If there is one thing we can be certain of this season is that there will be increased disease pressures given the crazy weather we’ve been experiencing. As we come into winter one of the diseases that can be prevalent is Winter Fusarium.
 
The following conditions tend to lead to this disease:

  • More than 10 hours a day of foliar wetness for several consecutive days;
  • Cool temperatures; 0 - 10°C are most favourable
  • Soil high in nitrogen fertility and low phosphorous and potassium; and
  • Areas with slow growing conditions and heavy thatch.

One of the most economical and effective ways to prevent winter fusarium out of bentgrass and Poa annua greens is by using fungicides at the correct time and rates. An application of INSTRATA in early May at 18 L/ha will clean out and protect turf – it can halt existing infections immediately and prevent new ones from occurring, all in the one application via rapid systemic action and translaminar activity.

Following up with HEADWAY MAXX in early June at 9 L/ha will ensure turf is protected and any disease encroachment is stopped for up to four weeks. By rotating these two powerful fungicides you can ensure a robust defence against Winter Fusarium and peace of mind for 28 days after either product’s application. Additionally, the comprehensive range of Syngenta fungicides gives you the option to follow these initial applications with long-lasting MEDALLION in July and trusted HERITAGE MAXX in August. The ability of MEDALLION to bind to the leaf surface quickly allows the early curative window to be wider than is possible for other contact fungicides. As turf growth rates slow down and mowing descreases due to reduced soil temperatures, this unique mode will lead to even longer efficacy and control of Winter Fusarium making it a perfect option in July/August.
