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.
"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
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 that coincide with egg hatch and
initial larval activity.
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 0.6 litre containers. One
application per year is permitted, with the latest time of treatment being 30
September 2019.
This
season, an on-lineturf pest ID guide, to aid the identification of adult stages of key target
soil pests and target application timing, is now available on the Syngenta
GreenCast website, along with Best Use Guidelines and application advice.
Turf
managers or owners who believe they have suffered economically damaging effects
of chafer grubs and leatherjackets are advised to contact their ICL Area
Manager or BASIS-qualified agronomist/distributor in the first instance.
