Operator Safety

MERIT® TURF is a NON-anticholinesterase/ organophosphorous compound. It offers very low risk to operators and non-target organisms. MERIT® TURF has been registered in the US under the same name since 1994 as a low risk insecticide.

Mode of Action

MERIT® TURF works in the following ways:

-	Insects that have ingested or absorbed the imidacloprid stop what they are doing or suspend normal behaviour.
-	Insects stop feeding immediately and do not survive.
-	The grubs will either be affected by eating the turf roots (where the product has been transported systemically) or by absorption through their outer body.

Application Timing

Applications should be made prior to anticipated pest infection to achieve optimum levels of control (prior to egg hatch), normally from middle of May to middle of June. Alternatively when identification of damage to turf is seen. This period can normally be anticipated when you see the beetle eggs in the soil. One application per year is needed for chafer grub and leatherjacket control with an application made in late spring/early summer.

Merit® Turf Trials

In trials that have run in the UK over a two year period, MERIT® TURF on many sites achieved 100% control at 4.5 months (135 days) and continued this success at 11 months after treatment. These sites often had populations of chafer grubs of over 1,000 per m2 . Out of the many trials put down an average efficiency of over 80% was seen after 4.5 months.

Other Benefits

The active ingredient imidacloprid also produced a 50% increased greening effect and increased the grass vigour by up to 90% in treated areas.
