Observations from the Trial Plots

SRF Alder

  • Caterpillars are stripping leaves from a couple of the Alder saplings (branches are now bare on a couple of branches).
  • All are alive – None have died.

SRF Black Locust ‘Turbo’

  • Weeds are under control after 2 sprays with Herbidome over the last 3 months.

SRF Black Locust ‘Turbo Obelisk’

  • The Black Locust ‘Turbo Obelisk’ is seeing plenty of healthy growth and multiple stems.

SRF Eucalyptus

  • The main shoots on some Eucalyptus nitens have snapped. They have broken over the tops of the tree guards in strong winds.
  • Weeds are under control after 2 sprays with the Herbidome 350 over the last 3 months.

SRF Poplar

  • Weeds are under control after 2 sprays with the Herbidome over the last 3 months.
  • Tree Guards are working well protecting the saplings from Glyphosate whilst using the Herbidome.

SRC Poplar

  • Weeds are under control after 2 sprays with the Herbidome over the last 3 months.
  • Tree Guards are working well protecting the saplings from Glyphosate whilst using the Herbidome.

0.5 ha Miscanthus Giganteus

  • Grass weeds were growing amongst the Miscanthus – We have been advised to wait until the crop is dormant in February/March 2024 then spray with 360 Glyphosate and flail/cut the Miscanthus just above the grassweed within 25 hours of application. This is to ensure that no Glyphosate finds its way into the Miscanthus Rhizome.

Sida

  • The Sida is growing well, with healthier rhizomes at the top of the plot
