Monitor chafer beetle numbers now

Monitor chafer beetle numbers now: Now is the time to start monitoring chafer beetle numbers to allow effective control of their vulnerable offspring with entomopathogenic nematodes, advises an industry expert.

“Chafer grubs can be extremely damaging to golf courses and with limited chemical options available for controlling them, the use of entomopathogenic nematodes can be an effective and natural way to protect courses this season,” explains Dr Colin Mumford, technical manager at Bayer.

To get the application of nematodes right, Colin explains that timing is crucial.

“Over the past few years, we’ve seen that chafer beetles have been emerging six weeks later than normal, so it’s important to start monitoring for activity during May and continue to do this throughout the season,” he says.

“This can be achieved by simply looking for the beetles, but to get a more definitive measurement I would use pheromone traps,” says Colin.

“The beetles are usually active for a couple of weeks, so look for the point when their numbers start to decline in the traps. You should plan to apply the nematodes three-to-four weeks after this point, as the eggs they have laid would have hatched by then.

“By getting this timing right, the nematodes will be primed and ready to attack the chafer grubs at their most vulnerable stage, when they are newly hatched or juvenile,” he says.

Colin notes that it is also important to get the application process right as well as the timing.

“Pick an overcast day with a soil temperature above 12ºC to apply the nematodes, as direct sunlight will kill them and cold temperatures will limit their activity,” he says.

“Irrigate the area the day before to ensure there is adequate moisture for the nematodes, and it will help them move through the rootzone.

“Make sure to remove all filters from your sprayer and spray nozzle, as this can cause blockages,” adds Colin.

He also explains that it is important to use whole packs, if possible, as some will contain more than one species, that won’t be evenly distributed throughout the pack, so by using whole packs you’ll get a good mix of species.

“For example, Bayer’s nematode product, Harmonix Tri-Nema, contains three different species of nematode,” he says.

“This combination of nematodes provides better control of the grubs because each species tries to outcompete each other to become the dominant species, meaning they are far more aggressive than they would usually be.”

Colin adds that it is important to maintain good soil moisture for a couple of weeks after the application, but warns not to over irrigate, as you will either flush the nematodes through the rootzone and down the drain, or simply drown them.

“Nematodes can be a very good option for controlling chafer grubs, but it’s important to get the timing right to target the grubs when they are at their most vulnerable to maximise control,” he concludes.

SALTEX to reschedule to March 2021

SALTEX to reschedule to March 2021: In light of continued restrictions surrounding mass gatherings, combined with the unprecedented impact on all of us from Covid-19, the Grounds Management Association’s (GMA) Board of Directors has taken the unanimous decision to move SALTEX to early Spring 2021. This outcome has been guided by discussions with key industry bodies, as well as exhibitors.

Like everyone else, the GMA has continued to follow Government guidance, and the science involved, to guide its business during this unprecedented time. Despite early optimism, a decision has been made to move the exhibition to March 2021 – taking into account the best interests of all parties involved.

By acting now, it gives the sector an opportunity to re-group and recover ahead of the next trade show. SALTEX will be now held on 3 and 4 March 2021, and the GMA is also realigning the following year so that SALTEX runs in Spring 2022.

The GMA’s decision is based on ensuring the safety of everyone connected with such an event. The association believes this is the most responsible course of action – given current circumstances.

Speaking about the announcement David Carpenter, Independent Chair of the GMA stated: “We would like to reassure our community that personal wellbeing remains our top priority. It is a case of mixed concerns at the moment, but I am hugely optimistic because I believe that the rescheduling of SALTEX in November 2020 will result in a much stronger show in Spring 2021. The new date will enable even more people to visit and celebrate the innovation, technology and the passion that the grounds industry represents – including excellent networking opportunities, as well as focussing on new business needs.”

Geoff Webb, CEO at the GMA said: “This has been a difficult decision to make, and I hope all our exhibitors join forces with us to mark a return to more ordinary working conditions in the not too distant future. Professional and personal lives have been placed on hold, and that in turn will have a knock-on effect. We want to help ease that load at the moment.

“We’ve seen the grounds community come together and adapt during this challenging period, and we hope that exhibitors help us host something beyond a trade show – a celebration of what our industry can overcome when working together.”

The GMA also believes that holding the 75th SALTEX on 3 and 4 March 2021 will help all companies get the respite required to readjust to changing professional and personal circumstances. The organisation understands the impact of Covid-19 for many businesses and individuals within the grounds management industry.

Geoff Webb continues: “Next year, the event will provide a huge opportunity for our sector to regroup, reunite and celebrate. After this difficult period, the show will help to rekindle the economic activity of the industry. Until then, all our thoughts and support are with those facing the challenges posed by the spread of Coronavirus.”

GMA is pleased to be able to honour all existing bookings and has also secured the same halls at the NEC to minimise disruption for exhibitors. It is also in the process of contacting exhibitors with new payment terms, with later dates, and it is also working with companies that may require further assistance during this challenging period.

The GMA and its SALTEX partners are working closely together to assist businesses with the transition. The GMA can be contacted for further support via SALTEX@thegma.org.uk.
