Royal Ascot Golf Club trials robot mowers

/in , , /by

Royal Ascot Golf Club trials robot mowers: A fleet of robotic mowers which reduces carbon emissions and enhances greenkeeping capabilities is being trialled at Royal Ascot Golf Club as part of its development strategy.

The Winkfield Road venue introduced BigMow technology to its 150 acre wooded Crown land course this week with a view to further enhancing the playing quality and experience of members and visitors alike.

Each mower is capable of cutting rough, semi-rough and fairway patches of ground for two hours using GPS technology, can operate in all weather conditions and will save an estimated five tonnes of carbon emissions each year – the equivalent of a return journey by plane from London Heathrow to Perth.

It is hoped the move will streamline tasks currently delegated to the club’s team of eight greenkeeping staff who will be able to invest more resource into green preparation, aeration, top dressing and overall presentation.

The demo will help the club to better understand how technology can be used to its advantage in the long-term with a fleet exchange planned for 2027.

Benefits of BigMow technology

Ian Hockley, Course Manager at Royal Ascot Golf Club, said: “The benefits of BigMow technology to the club are fourfold.

“Mowing is typically a greenkeeper’s most laboursome task, and although we always aim to be out on the course during quieter hours the occasional disruption to play is inevitable.

“Robotic mowers operate with minimal intrusion and are efficient at providing the best playing surface on areas of rough and semi-rough ground plus our fairways. This allows our existing greenkeeping team to prioritise tasks elsewhere on the course which will be a huge asset for us.

“There’s the environment impact too and due to the weight of each robot we can confidently send them out on the course when conditions wouldn’t be suitable for heavier, more traditional, machinery.

“We’re excited about the benefits this can bring to the aesthetics and playing quality of our course which we take great pride in.”

The trial is taking place after Royal Ascot Golf Club’s senior leadership team attended this year’s BTME Exhibition in Harrogate, Europe’s leading greenkeeping and turf management show.

The exhibition allowed the club to explore the latest equipment, learn about sustainable practices and attend a series of seminars.

Stephen Nicholson, General Manager at Royal Ascot Golf Club, added: “We’re continually exploring how we can remain at the forefront of greens maintenance to continue providing an enviable course in the years to come.

“Ensuring our through the door and playing experiences for members and guests alike are at the highest levels possible is a key priority for the team.

“Trialling BigMow technology forms part of this process and we’re grateful to AMS Robotics for their insights into how we can best utilise the technology while retaining our existing greenkeeping team.”

Diamond Green – Continuation of Product Trials

/in , /by

Diamond Green – Continuation of Product Trials: Indigrow developed Diamond Green as a liquid fertiliser based on potassium, calcium and magnesium. It contains essential plant oils to enhance plant health and increase disease resistance in turf grass. The combination of nutrients in Diamond Green improves the plants natural resistance to many known pathogens.

After the successful development the additive formulation, trials of Diamond Green at different application rates were carried out to assess its impact on the spread of Fusarium and Red Thread. It was tested three different application rates to assess it’s effectiveness.

Diamond Green – Continuation of Product Trials

Diamond Green – Continuation of Product Trials

Diseased turf cores were harvested from infected areas of turf on a parkland golf course. The cores were harvested in late Summer 2021 when these diseases were very active. Disease levels were consistent across each core at the time of harvest.

Throughout the trials, our aim was to find our the effectiveness Diamond Green had of different turf grass diseases without killing the fungus. As Diamond Green is a fertiliser with additives, it was important for us to show how this formulation would prevent the spread of the fungus within the cores taken from the parkland golf course.

Treatments

The following treatments were tested for their potential to reduce disease spread in already infected turf stands:

Number               Treatment                                                                                                           Rate

1                              Water:                                                                                                                  Untreated

2                              Fungicide (Tebuconazole 200 g/lt + Trifloxystrobin 100 g/lt):         1 lt/ha

3                              Diamond Green:                                                                                              10 lt/ha

4                              Diamond Green:                                                                                              20 lt/ha

5                              Diamond Green:                                                                                              40 lt/ha

Methods

The turf cores were harvested for each treatment, one infected with Fusarium Patch and one infected with Red Thread. The cores were then sprayed with each treatment until the turf surface was fully covered. The treated turf was then sealed in clear boxes to provide the humidity conducive to active disease spread. The development of the disease and the health of the turf was then monitored over the next 4-5 days.

Fusarium – Observations 4 Days After Treatment

Over a period of 4 days, the active Fusarium had spread freely on the untreated turf core and white, active mycelium was observed. The fungicide treatment has suppressed the spread of Fusarium, but there is still a small amount of active mycelium present.

Number               Treatment                                                                                                           Estimated Disease

Spread (%)

1                              Water:                                                                                                                  47%

2                              Fungicide (Tebuconazole 200 g/lt + Trifloxystrobin 100 g/lt):         14%

3                              Diamond Green:                                                                                              19%

4                              Diamond Green:                                                                                              8%

5                              Diamond Green:                                                                                              3%

At 10 lt/ha, Diamond Green has supressed the spread of Fusarium, but like the fungicide there is still a small amount of active mycelium present.

At both 20 and 40 lt/ha, Diamond Green has not only supressed the spread of Fusarium but allowed the turf to start to fill in disease scarred areas of turf. There is only a very small amount of active mycelium present on the turf

Red Thread – Observations 5 Days after Treatment

Over a period of 5 days, the active Red Thread has spread freely on the untreated turf core and active red areas can be observed.

At only 10 lt/ha, Diamond Green has had a limited impact on disease spread. However, at 20 lt/ha, the Red Thread has been almost completely suppressed and the turf has had a noticeable green up response and there is an obvious increase in growth rate.

Effect on Disease

It is important to state that Diamond Green is not a fungicide, it is a fertiliser with additives. We trialled both the fertiliser formulation without additives alongside the full Diamond Green formulation with additives. We found that when treated in isolation, the fungal growth is the same for just the fertiliser component as it is for the finished formulation containing the additives.

This confirms that it is the systemic acquired resistance within the plant that stops the spread of the disease.

Figure 2 – Diamond Green Final Formulation Fertiliser component + additives

Other Diseases

As Diamond Green acts as a trigger to the plants natural defences, rather than having a direct effect on the fungus itself, it is safe to assume that the activity shown here on Fusarium and Red Thread would be similar on other turf grass diseases including: Anthracnose, Dollar Spot, Snow Moulds and Leaf Spot.

Conclusions

The applications of Diamond Green have been successful in reducing the spread of Red Thread and Fusarium and the higher the application rate of Diamond Green, the stronger the effect is on disease.

At higher application rates of Diamond Green, the treatment also produces a strong growth response, with turf able to quickly ‘fill in’ previously diseased/scarred areas. Although this trial was only observational, we have a strong indication that Diamond Green can play a vital role as part of an integrated disease management strategy. With the benefits to turf health (shown by increased growth response and improved colour), we predict that turf treated with Diamond Green will have improved resistance to future disease attack.

Preventative Treatments Impress In STRI Trials

/in , , /by

Preventative Treatments Impress In STRI Trials: It has been proven in recent STRI research trials that preventative disease control programmes outperform curative options when analysed for turf quality, colour and presence of Microdochium Patch.

STRI research manager, Mark Ferguson, explains these results and stresses the importance of preventative programmes in light of the recent loss of curative active ingredient iprodione.

Preventative Treatments Impress In STRI Trials

“When measuring disease presence, the STRI team looked specifically at the level of Microdochium Patch cover on the plots. As expected, the preventative treatments performed significantly better than the curative ones.

“The trials ran over the course of eight months, comparing nine preventative and three curative programmes, as well as one untreated plot.

“The first three programmes used purely preventative fungicides from Bayer. The rest of the preventative plots used a combination from Rigby Taylor and Headland Amenity teamed with plant health products to reflect a more realistic approach,” says Mark.

In general, preventative programmes five to seven showed the most consistent results across turf colour, quality and Microdochium Patch presence by using an integrated approach with both fungicides and plant health products.

Preventative Treatments Impress In STRI Trials

“The fungicides within the curative programmes (11 -13) were applied as and when disease developed to an unacceptable level, mimicking traditional control strategies.

“It’s important to note that none of the trial plots had any cultural controls or biological practices applied prior to or during the trial, other than mowing and switching, which was carried out when necessary,” adds Mark.

Bayer technical manager, Dr Colin Mumford, says the trial results show that even the most ‘bullet-proof’ curative programme was significantly outperformed by the preventative options.

“The disease control landscape has changed and it’s more important than ever before that greenkeepers don’t wait for disease to appear as they may have done in the past,” he says.

Disease Management Trials

/in , /by

Disease Management Trials: This year’s STRI Research event will see Bayer continuing its study into disease prevention in pursuit of the best programme for tackling Microdochium Patch in light of recent losses to curative chemistry.

Dr Colin Mumford, Bayer technical manager, explains that the new research will build on results from last season’s set of trials, that showed preventative options outshone curatives.

Disease Management Trials

“This year the aim is to reinforce these findings and see how we can improve on current disease management programmes, with alternative and new products, as well as different application rates and timings.

“A variety of different fungicides will be put to the test, including Exteris® Stressgard® and Dedicate®, alongside a number of plant health promoting products, from two of our main distributors, Headland Amenity and Rigby Taylor,” he says.

“Once again, we’ll be testing the Microdochium Patch cover, colour and quality of the turf, with a variety of programmes including preventative fungicides, plant health products, and the last remaining curative options that mimic a more traditional approach.”

He points out that the conditions this year could be quite different to the low disease threat experienced by the STRI last season. “The turf has taken a bashing this summer, with prolonged periods of high temperatures and strong sunlight, so it’ll be very interesting to see how the turf fairs with a stressful start to the disease season.”

The trials are due to start in late August, to pre-condition the turf for improved health, and should run until spring 2019, to see if there is any effect on green-up ahead of the key playing season.

Colin explains that during the event, along with representatives from Headland Amenity and Rigby Taylor, the Bayer team will present on each of the combinations being applied to the plots, their regularity and the expected outcomes.
