New Bio Solution to Leatherjacket and Chafer problems in fine turf

Leatherjacket damage on bowling greens has been a huge problem already this year, so it is with a bit of relief that I am adding a new biological leatherjacket and chafer grub treatment to the shop today.

Introducing Harmonix® Tri-Nema™

Chafer grub and leather jacket infestations within your turf not only cause damage by their presence, but they also encourage further destruction by enticing predators like Crows and Starlings to their location, who in turn can cause untold losses to a healthy and vibrant surface whilst feeding.

This is why Bayer have helped to develop and patent Harmonix® Tri-Nema™, to give you 3 different modes of activity in one Nematode treatment.

Large infestations and presence of these predators can be a very costly experience within the environment of the turf you are caring for. From unsightly playing surfaces and course closures to potentially dangerous running surfaces, the potential for costly problems is always a large consideration.

Harmonix® Tri-Nema™ has three answers to the one question of how to effectively control these problems…
