Otterbine diffuses the situation

July 1, 2020/in News, Press Release/by Rosie Duckworth

Otterbine diffuses the situation: May was the sunniest calendar month on record and with the way things are going it may well not hold that title for long! So, this year more than any other year, water management specialist Otterbine is advising greenkeepers to be pre-emptive to the challenges hot weather can throw at lakes and ponds.

Water left unattended for long periods of time can very quickly deteriorate, especially as the weather warms up and as it’s predicted this summer will be a hot one – some say reminiscent to that of 2018 – it cannot be underestimated how important it will be to manage water quality.

Otterbine diffuses the situation

Warm water, plentiful sunlight and an excess of nutrients is a combination that, without a proper water management system in place, can leave lakes and ponds with problems such as algae, aquatic weeds and odours.

Simon Powell, Otterbine business development manager at distributor Reesink Turfcare, explains why it’s vital to implement preventative measures now, he says: “Oxygen depletion or stress situations occur for different reasons, but many lake management issues are related to both the light and heat generated by the summer sun. We understand that for some, water management may not be top of the to-do priority list, but it really does pay dividends to act now before the problems take hold.

“Once a lake has lost its ecological balance and goes into crisis, the costs of restoring the lake increase dramatically. As well as often being more expensive to implement, reactive solutions tend to be less friendly to the environment too.”

Low oxygen levels, combined with minimal circulation, prematurely ages water and throws the natural ecosystem out of balance. Only then do symptoms of poor water quality begin to appear, which as well as algae, weeds and odours, include sludge build up and aquatic life struggles or is killed off.

Simon says: “By increasing oxygen levels and circulating oxygen rich water throughout a lake, water quality can remain high, inhibiting algae, aquatic weeds and unpleasant odours. The most natural water quality management solution is to introduce aeration into a pond or lake to eliminate stagnant water. That’s where Otterbine’s aeration systems can help.”

With Otterbine’s aerating fountains, industrial aerators and diffused air systems and their proven high oxygen transfer rates, you can easily increase the dissolved oxygen levels in your lake or pond, preventing or curing stagnant water, algae build up and bad smells for clean, clear, healthy water. And with Otterbine’s decorative range you can make your lake or pond an appealing beauty spot at the same time.

Leatherjackets target for new Acelepryn Emergency Authorisation

July 1, 2020/in Press Release, Technical/by Mark Sanderson

Leatherjackets target for new Acelepryn Emergency Authorisation: A further new Emergency Authorisation (EA) for the use of the Syngenta insecticide, Acelepryn, has been reapproved to target leatherjackets for the 2020 season.

The new leatherjacket specific authorisation supplements the summer chafer grub EA announced in May.

“Two individual EA’s allow a longer window of application to target the specific pests at the most appropriate timing for each- which coincide with the pests’ egg hatch and initial larval activity,” according to ICL Technical Manager, Henry Bechelet, who applied for the Emergency Authorisation on behalf of the industry.

The EA permits use of Acelepryn on affected greens, tees and fairways, along with horse race courses and airfields. The treatment period for leatherjackets is up until 31 October 2020.

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, he 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 in late July to the end of September, although hatching may be further extended into the autumn depending on weather conditions. Crane fly start to lay eggs almost immediately, depositing up to 400 eggs each in 80-100 batches.

The eggs hatch after approximately 14 days, when larvae start to feed on organic matter and roots, along with leaves on the surface around their holes. Optimum results have been seen from application targeted during peak egg laying, to target larvae soon after egg hatch.

“The extension of use to the 31 October could prove extremely useful to target later emerging leatherjackets. However, all orders must be received by ICL by 27 October, to enable necessary stewardship records and delivery,” added Mr Bechelet.

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, for the first time, Acelepryn users will be able to submit online stewardship records of areas treated, via the ICL website: https://bit.ly/AceleprynStewardshipForm2020

Syngenta Technical Manager, Glenn Kirby, advised the best results have been achieved with applications when young leatherjackets, at the 1^st and 2^nd 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 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 GreenCast website.
