GDD Calculator aids more accurate decisions

GDD Calculator aids more accurate decisions: A new Syngenta GreenCast Growing Degree Day calculator is set to provide turf managers with a more accurate tool to help make better decisions on timing for Primo Maxx II applications and other actions.

The GreenCast GDD Calculator will automatically generate a predictive email notification when a user defined Growing Degree Day (GDD) target is approaching – in time for greenkeepers to assess local conditions and to decide what actions to take.

GDD Calculator aids more accurate decisions

Commenting on the live launch of the GDD Calculator on GreenCast this week (11 May 2020), Syngenta Technical Manager, Glenn Kirby, said: “We know that GDD can be a useful guide to many turf management actions.

“However, from my own and other greenkeepers’ experience, the challenge in a busy working schedule is finding the time to regularly record the temperature information and the reliability of that weather data source.

“The GDD Calculator does that all autonomously, and provides easy to interpret information in time to use for every day decision making.”

Advancing GDD to a new level, the GreenCast calculator utilises immense data processing capability to compute figures from hourly temperatures throughout the 24-hour period, compared to a simplistic daily high and low temperature conventionally used in GDD calculation.

“That better reflects the duration of growing conditions through the day, for a more accurate assessment of how turf will actually perform,” advised Glenn.

Evaluation compared to conventional GDD calculation has highlighted it is more responsive to assess onset of true growing conditions, particularly through early spring, and as growth declines in the autumn.

Users can set their own target GDD figure, or multiple targets if GDD is being used to aid decisions on different aspects of turf management, such as Primo Maxx II intervals, fertiliser programmes or pest risks, for example.

Glenn highlights Growing Degree Days have been shown to be an extremely useful guide for timing of turf management decisions. But he cautions that much of the research and many of the models have been based on US trials, under different conditions and with different grass species seen in the UK.

“The Syngenta GDD Calculator gives far greater flexibility to be able to utilise and interpret a wide range of information resources. But they do all need to be validated against an individual course’s specific conditions to see how they can be applied.

Uniquely, the Syngenta calculator allows users to adjust the base temperature used in calculations. Whilst a normal base for the UK is 6°C, which reflects the onset of consistent turf growth, Glenn suggests, many US models work from a base of 10°C – which generates hugely different cumulative GDD figures.

“It is crucial to understand how recommendations have been calculated and the information on which they are based, and then use the GDD Calculator to interpret how that will work on your course,” he advocated.

Whilst a GDD of 150 may be appropriate for Primo Maxx II intervals on one specific course, for example, he points out another course with a different management style, turf species or soil types, may find they get better results by repeating applications at a GDD of 140.

The GDD calculator is now being used at STRI in Yorkshire, as part of a new initiative assessing Primo Maxx II applications and intervals to aid turf management under lower intensity lockdown management.

“For the first time, there will be scientifically assessed GDD data for cool season grasses under UK growing conditions, to enable turf managers to better interpret existing turf growth models for their own individual situations,” added Glenn.

”It is free and easy to use, so would urge anyone to start gathering the data and assess how it correlates to their own decision making process now, to be able to further integrate GDD in the future,”

The Syngenta GDD Calculator is available for all UK turf managers, agronomists and researchers registered on the GreenCast website.

AH75 the solution to excessive first cuts

May 11, 2020/in Machinery, News, Press Release/by Lucy Nicholls

AH75 the solution to excessive first cuts: With the impending difficulty some green space professionals will soon be experiencing from a delayed first cut, many are turning to the Etesia Attila AH75 brushcutter as a solution.

The Etesia Attila AH75 brushcutter offers ride-on performance in a pedestrian machine and has been designed to work in the toughest of conditions. This powerful workhorse effectively deals with clearing vegetation from a wide variety of sites – long grass, weeds, bracken and brambles on woodland paths or orchards. Ease of operation and manoeuvrability ensure total efficiency and high output.

AH75 the solution to excessive first cuts

At a time when many will be facing excessive first cuts, green space professionals – particularly those working for local authorities and landscape contractors, will find the Etesia Attila AH75 a cost-effective solution. At just £3,200 plus VAT, this reliable and powerful machine has been proven to outperform many of its counterparts at a fraction of the price.

The Attila AH75 is powered by the Honda GXV 390 engine and fitted with a T3 transmission combining differential lock and front wheel locking system with a simple height of cut adjustment from the new handle bar design which allows movement into offset for use on slopes.

Efficiency

Heavy-duty brush cutting (up to Ø30)
Mowing on the most difficult slopes (up to 20°) thanks to the hydraulic transmission with a differential lock
Two idlers that can be locked without a tool for improved stability on slopes
Possibility to fit two wider rear wheels as an option
Cutting height adjustment with three positions from the new handle bar design
Handle offset control from the operating position with three working positions and one transport position

Comfort

High manoeuvrability thanks to the hydraulic transmission – three forward speeds and one reverse speed
Differential lock can be engaged without interrupting movement
All operating controls are available from the operating position for convenience and safety
Central handle bar that allows easier access to low controls (parking brake, forward transmission bypass, engine starter), with full protection for cables
Parking brake for safe immobilisation
Anti-vibration rubber handles

Ruggedness

Machine can be moved into vertical position to gain access to the cutter blade for maintenance and cleaning
Maintenance-free hydrostatic transmission with forced-air cooling, integrated expansion vessel
Flail blades: reversible, protect the blade transmission system, low maintenance costs
Rugged and reliable engine: Engine crank shaft mounted on bearings.

A full two-year commercial warranty comes as standard.
