Industrial Vegetation Management
Scrub, brush and woody weeds are a common sight in both urban and rural areas. These weeds can cause damage to private and public property if left uncontrolled, adversely affecting infrastructure, buildings and the biodiversity of the landscape.
Many of these weeds are extremely difficult to control, due to their hardiness and aggressive rates of growth. Not only do they require treatment at different times of the year, they may also require a variety of control methods in order to achieve optimum results.
The presence of woody weeds along railway lines lead to many safety problems. These include:
Motorway and Carriageway Embankments
Safety can also be compromised if weeds are left uncontrolled on roadsides.
Electricity Power Lines
The Key Weeds:
Ragwort, docks, thistles and other herbaceous weeds can be effectively controlled using SYNERO*, active ingredients floroxypyr and aminopyralid. Again, SYNERO is safe to grasses, making it the logical choice for motorway and railway embankments.
Woody Weed Species
Bramble, broom, gorse, rosebay willowherb, buddleia, Japanese knotweed and other woody weeds can be controlled using a managed approach with products containing the active ingredient triclopyr, as found in Garlon* 4 and Timbrel*. Woody species can be controlled with Timbrel and Garlon 4 using a variety of application methods at different times of the year. These include cut stump, winter shoot, basal bark and foliar treatments.
Where thistles are a problem in addition to woody weeds, Blaster*, containing triclopyr plus clopyralid, would be the product of choice.
Triclopyr degrades rapidly in the soil, allowing planting to take place from six weeks after application. In many situations where scrub, brush and woody weeds have to be controlled it is desirable to leave grass cover. Not only does this provide vital wildlife habitats, it also prevents soil erosion and enhances the appearance of treated areas. Blaster, Timbrel and Garlon 4 do not damage grasses and can be used with confidence where cover needs to be maintained.
Japanese Knotweed (Fallopia japonica), mugwort and other difficult to control species can be controlled with products containing the active ingredient picloram, such as Tordon* 22K. Picloram has both foliar and residual action, and is safe to grasses. The use of Tordon 22K to control Japanese knotweed can quickly lead to increased biodiversity, as native grass species recolonise treated areas as soon as the weeds have died back. Broad-leaved species of desirable plants can naturally recolonise treated areas in subsequent years after application.
