Emergency Authorisation for Acelepryn reapproved for turf

Product Update
Chafer and leatherjacket grubs

The Emergency Authorisation for the use of the Syngenta insecticide, Acelepryn, for the control of chafer grubs and leatherjacket has been reapproved for the 2019 season. The request was applied for by ICL, on behalf of the amenity industry.

Chafer grubs and leatherjackets cause damage to turf through extensive feeding on roots, which can be severe in localised patches. Furthermore, extreme damage can occur when badgers, birds and other foragers root through turf in search of the grubs.

The Emergency Authorisation permits Acelepryn use in situations where there is an acknowledged instance of economic damage, or risk of bird strike on airfields, and where the product has been recommended by a BASIS qualified agronomist.

This season, ICL’s work has seen the authorisation extended to permit limited use on affected fairways, as well as greens, tees, horse race tracks and airfields.

Acelepryn can be applied up until 30 September 2019, to cover the key chafer grub and leatherjacket treatment timings - targeted to coincide with egg hatch and initial larval activity. 

 ‘”Since the withdrawal of effective insecticides, economic damage from chafer grubs and leatherjackets has been of major concern,” reported ICL Technical Manager, Henry Bechelet.

“Obtaining this Emergency Authorisation of Acelepryn enables us to manage the most damaging effects of these soil pests as part of an integrated turf management programme.”

The authorised label permits application at the rate of 0.6 litres per hectare, applied in 600-1000 l/ha water and, ideally, irrigated in after application.

Acelepryn is supplied through ICL in one litre and, new for 2019, 0.6 litre packs.

One application per year is permitted, with the latest time of treatment being 30 September 2019.
