Electric Weeding Demonstrations

In conjunction with Kazel Cass at Hotgrass, we have a couple of electric weeding demonstrations coming up. So if you’re interested in non-herbicide non-mechanical weeding, get along for a personal encounter.

Option 1: Gisborne
  • 9am – 10 am
    Wednesday 6 December
  • At first car park going up Queens Drive, Titirangi Domain
    (Kaiti Hill), Gisborne

Hotgrass uses the RootWaveTM Pro Electrothermal Weeder technology designed and manufactured by RootWave in the UK. They suggest this is:

  •  Sustainable, using a generator it uses a fraction of fuel required for thermal (steam, hot water) weed control.
  • Organic, the only input is electricity.  No need to carry tonnes of water, or toxic agri-chemicals
  • Effective, trials in the UK show it is effective against some of the toughest weeds because it gets down to the root of the problem.  It is able to control weeds that are resistant to herbicides
  • Manoeuvrable, because the device has a small footprint, and doesn’t require any water, it can be loaded onto small utility vehicles

Charles Merfield, head of the BHU Future Farming Centre, has reviewed electric weeding. His very detailed review is here. Worth your time reading too.

Sustainable Weed Management Workshop

Approaches to the non-chemical / sustainable management of weeds

Full House at Weed Control Workshop.

With the increasing and well know issues surrounding herbicides, such as resistant weeds, ‘resistant’ consumers and increased regulation, non-chemical/herbicide weed management is becoming increasingly important. 

Growers are well aware of the limitations of current weed management tools and practices. They recognise simple chemical solutions are increasingly limited and more sophisticated management is essential.

In response to this need, the BHU Future Farming Centre, NZ’s leading specialist sustainable agriculture research centre, and LandWISE with its focus on sustainable production through technology ran a non-chemical weed management workshop to give attendees the knowledge and tools they need to make significant enhancements to the long-term sustainability of their on-farm weed management practices. 

Topics covered included the context of weed management, essential weed biology and ecology, integrated weed management plus detailed coverage of field operations and machinery.   Full information can be found at www.bhu.org.nz/future-farming-centre/events/one-day-seminar-workshop-on-non-chemical-weed-management

Dr Charles Merfield, Head of the Future Farming Centre, said “the aim of this practically focused course was to give attendees a sound overview of the whole of non-chemical weed management as well as providing practical details about how to implement the ideas once they get back to the farm.” 

The feedback from attendees was very positive and we anticipate running this again next winter. We already have a wait list so contact us if you are keen info@landwise.org.nz
