NemaTrident techniques to target chafer grub larvae

/in , /by

NemaTrident techniques to target chafer grub larvae: Chafer season has been slow to start this spring, but is now taking off with adult beetles emerging. Moist soils now make ideal conditions for egg laying, with warmer temperatures for larval hatch and feeding activity.

However, warm and moist soil conditions are also ideal for beneficial nematode action to target larvae in the early stages of the life cycle, advises Syngenta Technical Manager, Sean Loakes.

“Soil temperature consistently above 12⁰C for at least three hours a day are ideal for the NemaTrident B nematode species, Heterorhabditis bacteriophora, that has been specifically selected to effectively target chafer larvae.”

“NemaTrident B can provide highly effective control of chafer larvae. New trials have shown how we can now best harness the beneficial nematodes in effective Integrated Turf Management strategies.”

He points out that chafer control with nematodes is a numbers game, with the more nematodes applied in the optimum conditions, the greater the opportunity for sufficient parasitic worms to get into the active larvae.

“Chafer grubs are remarkably adept at avoiding nematode attacks, using their pseudo legs to wipe nematodes off their torso. However, if there are sufficient nematodes present they will overwhelm larvae, with potential for good results even on larger instar grubs.

“It’s important to select the most appropriate nematode for the target pest, and applying the maximum number in the best condition. Using a product with a mixed population of different nematodes species could result in too few of the required nematodes in the soil zone or inactive at lower soil temperatures,” he warns.

NemaTrident B nematodes are particularly active at seeking out chafer grubs in the soil. Once they penetrate into the larvae, they release a bacteria that kills it. Nematodes move through the soil in a film of moisture, so are best applied when soils are moist and ideally kept irrigated or moist for 14 days after application. Unirrigated sites pose a serious challenge for nematode use, where they should be applied in a period of rainfall.

“NemaTrident should be applied in conjunction with NemaSpreader, a bespoke blend of surfactants designed specifically to retain the conditions for optimum nematode movement in the soil.” Trials have shown up to 30% better soil pest control when NemaTrident is used in conjunction with NemaSpreader.

Sean advocates NemaTrident B application should be timed after the point of peak adult chafer activity and egg laying, to ensure the nematodes are in the soil profile as the larvae are emerging after three to four weeks; young larvae are the most effectively controlled.

Establishing which species of chafer beetle is the key target species will influence optimum application timing, as well as the population of larvae to be controlled, he highlights.

The most common garden chafer, for example, are typically most active egg laying through mid to late June and only have a one-year life cycle that can be especially well targeted for control; while the summer chafer is most active in July and August, as well as having two-year life cycle that is more difficult to control where older large grubs are present.

“That makes timing and application technique so important to get the optimum results. Nematodes are living organisms, and as such have to be treated carefully from delivery, through storage and to application that will ensure the maximum number are applied in the best condition.”

Seans Top Tips for success with nematodes include:

  • Store in the fridge at 4-7⁰C as soon as possible on delivery
  • Pre-mix in lukewarm water before adding to the spray tank
  • Remove filters from the sprayer and ensure it is clean
  • Apply in a water volume of 500 – 1000 litres/hectare
  • Use the Syngenta XC 08 Soil Nozzle
  • Always use NemaSpreader with NemaTrident applications
  • NemaTrident B should be applied at a rate of five billion nematodes per hectare

Syngenta trials have shown the most reliable and consistent chafer grub control with an integrated approach using NemaTrident B plus NemaSpreader, following an Acelepryn insecticide treatment.

Recent studies at Forest Pines Golf Course in Lincolnshire – using a well-timed application of Acelepryn at peak egg laying, followed by NemaTrident B – have confirmed that larger chafer larvae stressed or weakened by Acelepryn may prove more susceptible to nematode incursion, to deliver more effective and reliable overall control.

“Where chafer grubs are the primary target this two-pronged approach can give the optimum results,” reports Sean.

“However, turf mangers and agronomists must be aware that only one application of Acelepryn is permitted per season and with limited treatment area, so if leatherjackets are the greater issue the insecticide may be better utilised there, and NemaTrident B the key asset for chafer grub control.”

Navigating Unpredictable Weather and Its Impact on Lawns

Navigating Unpredictable Weather and Its Impact on Lawns: If there’s a saying about the UK’s weather, it should be: “The only thing predictable about the weather is how unpredictable it is.” Right now, we’re experiencing a bewildering mix of sunshine, rain, and everything in between. This unpredictability makes planning outdoor activities, including gardening, quite challenging.

Despite the billions spent on weather forecasting, the reality often feels like a joke: “Rain, with showers at times, drying up to become wet later.” This sentiment resonates with millions of gardeners across the UK, who are left wondering, “Where are the droughts we were warned about?”

Navigating Unpredictable Weather and Its Impact on Lawns

For lawn enthusiasts, especially those with native bent and fescue grasses, the current weather is less of a hassle. These grasses don’t require annual overseeding. However, for those using ryegrasses, the constant rainfall can be a real nuisance. Seeds can become too wet, get washed away, and by the time the lawn looks decent, autumn is already here. Ryegrass might be popular for sales, but it brings its own set of challenges.

So, what can lawn owners do right now to manage their lawns amidst such unpredictable weather? Surprisingly, the answer is: not much. The ever-changing weather means that a heatwave could be just around the corner, and soon enough, you might have to start watering.

At this time of year, the focus should be on protecting your lawn. The sun can cause significant damage, so maintaining healthy grass is crucial. Here are some simple yet effective tips:

1. Mow Regularly: Frequent mowing with sharp blades reduces stress on your lawn. Consider using a robotic mower that can handle daily mowing, allowing you to relax and enjoy your garden.
2. Use Organic Fertilisers: Opt for organic options like True Grass to avoid scorching and promote healthy growth.
3. Water Wisely: If watering is necessary, do it at night so the plants can absorb the moisture more effectively.
4. Enjoy Your Lawn: If you’re not enjoying your lawn by now, it might be time to rethink your approach for next year.

Remember, during extreme weather, simplicity is key. Overworking your lawn can lead to more harm than good. Keep these tips in mind, and you’ll be better prepared to handle whatever the weather throws your way.

Water Savings and wash-off

/in , /by

Water Savings and wash-off: Minchinhampton Golf Club has three exceptional golf courses, all of which are renowned for their year-round immaculate presentation and excellent drainage.

Keeping all courses in such condition involves a dedicated team of greenkeepers and an expanding fleet of machinery and kit. Course Manager, Adam Matthews, can be justifiably proud of his team’s achievements. However aware of the impact on the environment that washing off so many machines could have, his and the club’s attention focused to address the issue. Two matters were of important consideration: 1) The conservation of water and obligation to sustainability  and 2) Prevent pollution of the ground water ensuring compliance with current Groundwater Regulations. Adam believed that a new wash-off facility with water recycling was the only way forward and researched suitable solutions.

Water Savings and wash-off

A ClearWater washpad recycling system from Acumen Waste Services looked to be the ideal solution to him and a site meeting was arranged. Following this visit by the company, specifications were drawn up and a quotation provided.

As there is a rather large fleet to maintain, a larger dedicated washpad was agreed upon and, instead of a 5000-litre standard system, one of ClearWater’s 10,000 litre capacity recycling systems with a four-hose wash-off facility was agreed upon and an order was placed. ClearWater’s Matthew Mears explained: “With sustainability being a major factor in business thoughts and multiple machine washing at one time, ClearWater’s 10,000 litre (2640 gallon) capacity is more than adequate and also allows greater dwell-time for the biological treatment.” Minchinhampton chose a turnkey package quoted by Acumen ClearWater and all work was carried out within a week schedule.

So, what made ClearWater the choice for the club? The club takes their environmental responsibilities seriously and sustainability is a major concern, so a compliant washpad and water savings became a must. Adam Matthews said; “ClearWater fitted the bill! It’s great to ensure we are doing our bit for sustainability and efficient wash-off” ClearWater does provide certain advantages over other solutions however: The system is located adjacent to one of the fairways and, as ClearWater is a below ground system is most unobtrusive, just turret tops at ground level may be visible! There’s no noise either, all you will hear is the washwater jet leaving the water guns! Also, the system recycles treated water with very little loss, as the dedicated washpad with it low curb surround is constructed in such a way as the waste wash water is discharged through grass traps and into the underground tank by gravity for treatment. Naturally, some water loss will occur through evaporation, particularly in hot weather. However, the system is topped up by rainwater falling on the washpad (not an uncommon site these days!); sustainability at its best and at no cost!

Machinery wash-off for many has clearly demonstrated huge water consumption and wastage for many years at an ever-increasing cost, financially and environmentally. Water has become an increasingly valuable resource. Washpad water recycling is the way forward for those in the turfcare maintenance sector and other business needing wash off. With water savings in excess of 90% possible, sustainability really does then become a meaningful word!

Former Leyland Golf Club course manager joins BIGGA team

/in , /by

Former Leyland Golf Club course manager joins BIGGA team: The British & International Golf Greenkeepers Association (BIGGA) has appointed Scott Reeves as Head of Membership, overseeing the development of the association’s membership activities.

Scott, 53, was formerly the course manager at Leyland Golf Club, where he spent 17 years. He began his greenkeeping career at Wycombe Heights Golf Club, Buckinghamshire, followed by spells at Stock Brook Country Club in Essex and Chobham Golf Club in Surrey, before relocating to Lancashire in 2003. He spent three years at Preston Golf Club before a one-year stint with Saxon Industries in a sales role. He then returned to course management at Leyland Golf Club in 2007.

Scott has volunteered at every level of BIGGA, culminating in his appointment as chairperson of the association in 2019. The COVID pandemic hit during Scott’s term and he worked closely alongside BIGGA CEO Jim Croxton, the BIGGA staff and National Board as the association navigated the turbulence of that period, ensuring BIGGA was well-placed to offer support and guidance wherever required.

Following his term as chairperson, Scott retained an involvement with BIGGA and still lectures on the Golf Club Management Diploma, jointly run by the GCMA, PGA and BIGGA. He was also a part of the Committee for Golf Club Salaries for many years.

Following a recent restructure, the Head of Membership position has been created by BIGGA. Scott will be responsible for ensuring the development and implementation of the association’s membership strategy, as well as taking on a senior leadership role within the organisation. He will work closely with all BIGGA departments to ensure the association is fulfilling its responsibility to members, while seeking to evolve BIGGA’s activities and offering.

Scott said: “What attracted me to this job is it is such a huge opportunity. One of the things I really valued in my time as a greenkeeper volunteer with BIGGA was the chance to make the world a better place for greenkeepers, as we always say. With a little time away, focusing on my own job as a greenkeeper, it’s helped me see just what a valuable resource BIGGA is.

“What I’d say to BIGGA members is that another one of us has joined the association. I’m someone who understands you and understands your challenges as I’ve faced many of them myself. We’re here to help you, to serve you and to make sure that you can access everything BIGGA has to offer, to build a better career for yourself and a stronger industry for everyone.”

BIGGA CEO Jim Croxton said: “We worked hard to identify the correct candidate for this position and we put all the applicants through rigorous testing as the Head of Membership will play a key role in shaping the future of the association for years to come.

“We had some outstanding applications but Scott’s passion for greenkeeping and belief in the value BIGGA brings to the industry shone through. He has been involved with committee work at all levels, including chairing the association from 2019 to 2022, a period which included the COVID pandemic and was therefore one of the most challenging of any in our history.

“I’m excited that Scott has joined the Association and look forward to embarking on what I believe is the next chapter in BIGGA’s history.”

A video of Scott discussing his new role and ambitions for the future is available to watch online here.
