Programmes to beat turf disease Syngenta Technical Manager, Simon Barnaby, reports
Turf diseases are becoming more aggressive – hitting earlier and going on for longer. Yet players’ demand is for ever higher quality turf, all year round. Both turf and turf managers are under increasing pressure to deliver.
Turf managers need to adopt new strategies to cope with disease, incorporating the latest new products and the most up to date technology to achieve the
best possible results.
Fungicide selection Turf fungicides work in a variety of ways; targeting disease at different points in their life cycle and with different modes of action. Syngenta fungicide programmes are designed to select the optimum choice for any disease, at any stage in the season.

Preventative fungicides, such as Heritage and Banner MAXX, have proven most effective in maintaining turf quality when applied just after disease infection has taken place, but before any symptoms are visible.
Where disease symptoms are already present, a fungicide with a powerful curative and eradicant activity, such as Daconil Weather Stik, must be used.
Well-timed preventative fungicide applications, using risk forecasts on
www.greencast.ie, can deliver the longest protection from effective products – with a reduced number of applications and lower cost.
