Rescue herbicide from Syngenta, is designed to allow greenkeepers and golf course managers to remove Ryegrass and some other coarse weed grasses, without affecting fine turf grasses.

Launched at St Andrews in Scotland, Rescue has been approved for the control of weed Ryegrass on all areas of the course, including greens, green surrounds, tees, fairways and roughs.

When applied during periods of active growth, the first visible effects of Rescue are typically seen on Ryegrass within 10 days. The whole process is usually then completed within three to four weeks.

It is recommended that the programme is started in the autumn, typically in September to October. This targets actively growing weed grasses and gives time for over sown seedlings to establish.

Syngenta UK Turf Manager, Simon Elsworth says: "Discussion with course managers has highlighted the beneficial potential to create thinner, more manageable roughs, which will make ball location easier and help to speed up play."
