Leatherjacket Acelepryn Emergency Authorisation

Leatherjacket Acelepryn Emergency Authorisation: A new Emergency Authorisation (EA) for the use of the Syngenta insecticide, Acelepryn, has been approved to target leatherjackets for the 2021 season.

The EA permits use of Acelepryn on affected greens, tees and fairways, along with horse race courses, training gallops and airfields.

This season, the treatment period for leatherjackets is permitted up until 29 November 2021.

“The extended application period does allow a longer window of treatment to target larvae activity from later hatching crane fly at the most appropriate timing,” according to ICL Technical Manager, Henry Bechelet, who applied for the Emergency Authorisation on behalf of the industry.

New Syngenta research has been investigating the optimum application timing in challenging situations, particularly where larvae activity may be occurring later in the season. It has also looked at the role of integrated measures to mitigate against leatherjacket damage, including adapting aeration and renovation strategies.

Leatherjackets cause damage to turf through feeding on roots and leaves – typically resulting in pock-marked and uneven surfaces, which can be severe in localised patches, Mr Bechelet pointed out. Racecourses and horse gallops are especially prone to surface instability where root damage is caused by soil pests.

Furthermore, extensive damage can occur in all turf surfaces when badgers, birds and other foragers root through turf in search of leatherjackets. Flocks of birds attracted to feed on larvae are of particular concern on airfields.

Leatherjackets are the larvae of crane fly (daddy longs legs). Adults typically emerge from July, although hatching may be extended into the autumn depending on weather conditions.

“The extension of use to the end of November could prove extremely useful to target later emerging leatherjackets,” he added. Mr Bechelet reminded turf managers and agronomists that all orders must be received by ICL in time to to enable necessary stewardship records and delivery

Acelepryn users can submit online stewardship records of areas treated, via the ICL website.

The new leatherjacket EA supplements the chafer grub specific authorisation announced in earlier this year.

Syngenta Technical Manager, Glenn Kirby, advised the best results have been achieved with applications when young leatherjackets, at the 1st and 2nd instar stages, are actively feeding near the soil surface.

“It’s important to apply at higher water volumes, using the white O8 XC Nozzle to target the spray through to the soil surface,” he advised. “Irrigation where possible will help to move the spray into the target zone.”

The authorised label permits application at the rate of 0.6 litres per hectare, applied in 500-1000 l/ha water. Only one application per year is permitted on any given area.

Greenkeepers and turf managers are urged to report sightings of crane fly activity through the on-line Pest Tracker. The aim is to build a picture of pest activity across the UK and Ireland, to anticipate issues and aid application timing. Further information and pest identification guide is available on the Syngenta Turf UK  website.

Emergency Chafer Grub and Leatherjacket Summit

Emergency Chafer Grub and Leatherjacket Summit: An emergency summit is to be held with the aim of finding industry-led solutions to the threat of Chafer Grubs and Leatherjackets in the turf industry.

The Summit will take place on 9th May 2019 at Burton Albion Football, Staffordshire.

Emergency Chafer Grub and Leatherjacket Summit

Attendance at this industry summit is vital to those in the industry that want to develop a long-term preventative strategy for Chafer Grubs and Leatherjackets.

Now that many of the chemicals which were routinely used to keep golf courses and sports pitches free of pests have been withdrawn, we need to find alternatives. This Summit will explore the current challenges in sustaining turf quality in a chemical-free environment.

Without proper preparation and action prior to May this year, there is a high risk of increased attack by Chafer Grubs and Leatherjackets. Many grounds personnel are unaware of a problem until they see evidence – such as birds picking insect larvae by uprooting the dead grass.  However, prevention is better than a cure and scientifically-developed natural pest control solutions when applied in advance will help control the problem.

This event is supported by Bionema, Rigby Taylor, Maxstim, EcoSpray and E. Marker A/S and is held in association with the editors of BIGGA, IOG and Horticultural Week, leading industry magazines.

Dr Minshad A Ansari, Founder and CEO of Bionema, said:

“This summit is the first step in working together as an industry – pooling our knowledge and using all the tools we have in an integrated way to achieve control of these devastating pests”

This emergency Summit will include:

Welcome and Introduction Dr Minshad Ansari, CEO Bionema

Case study 1: Chafer Grub control at the Grove

Case study 2: Leatherjacket control at Neath golf club

Mark Tucker, Head Greenkeeper, Neath Golf Club, UK

The event will establish the true extent of the problem faced by the turf and amenity sector, offer a better understanding of the pests and the current controls available. It will culminate in an interactive debate, chaired by BIGGA, IOG, Horticultural Week editors to help plan the next steps for the industry to take to combat the pest threat. The Summit will conclude with an insight into research and development into the control of Chafer Grubs and Leatherjackets in turf and amenity sector by Dr Minshad Ansari from Bionema.
