Syngenta business manager Daniel Lightfoot, a former course manager and master greenkeeper is advising use of Heritage Maxx.
Said Lightfoot: "The combination of early summer warmth and wet – from rain or irrigation – can quickly lead to damaging outbreaks of Fusarium on soft leaf tissue, which has already been widely reported this season.
"Any short periods of stress can see disease flare up. Whilst disease infection will grow out, the unacceptable effects of scar damage on playing surface quality could persist for weeks - especially with many club competitions coming up over the summer."
With turf actively growing, systemic movement was crucial, since contact or local penetrant fungicide treatment would quickly grow up the leaf and be mown off; a 3mm leaf growing at 0.4mm a day would see contact fungicide retention halved in just four days.
"With Heritage Maxx, the active continues to be taken up by the crown and roots and moved up through the turf to the growing leaf. That ensures sufficient fungicide active remains in the leaf to prevent disease for longer," he said.
"The continual recycling and redistribution of the active can give prolonged protection."
The activity of Heritage Maxx on soil-borne pathogens has been shown to further help with protection against summer Fairy Ring outbreaks and positively reduce the damaging effects of Take-all.
Syngenta application research has shown optimum results to target soil-borne pathogens can be achieved by spraying at a relatively low water volume, of just 200 to 300l/ha, and irrigating with 2mm to 5mm of water as soon as possible to move the Heritage Maxx into the root zone. Spiking or aeration prior to application did not see a significant advantage.
