Invasive plants

Managing invasive plants is essential to reduce ecological, economic, and health issues they cause due to their challenging growth patterns. However, because of how they grow, this can be very difficult.

There are two main types of invasive plants:

UK native invasive weeds – e.g. Field horsetail
Invasive Non-Native Plants (INNPs) from other parts of the world – e.g. Himalayan balsam

While Invasive Non-Native Plants (INNPs) and UK native invasive weeds can grow and spread quickly, INNPs introduced to the UK from other ecosystems are much more of a problem, as they don’t have their natural predators and diseases to keep them in check. As a result, they displace native plants (reducing native biodiversity), spread quickly along rivers and roadsides, and because they can grow very large and quickly, they can cause damage to property. In short, INNPs have few obvious benefits for the UK environment, society and economy, while they create many proven negative impacts.

In contrast, many difficult to manage UK native invasive weeds cause problems when people disturb and modify habitats – these plants are good at occupying the gaps that we create (admittedly, INNPs are also good at this!). Consequently, where we change our cultural practices, we can reduce the impact of many UK native invasive weeds without resorting to control measures. Also, UK native invasive weeds do have benefits, particularly with respect to the UK environment.

For example, Spear thistle seeds provide food for farmland birds such as Goldfinches, as well as thistledown which is used for nesting material. It is also a source of nectar for butterflies and a range of invertebrates overwinter in the stems.

Making this distinction between INNPs and UK native invasive weeds is important from an ecological perspective and understanding why targeted, long-term and effective (sustainable) management of INNPs is essential for the UK environment, society and economy.

Amenity Glyphosate XL is a foliar applied translocated herbicide for the control of emerged weeds in industrial and amenity situations, in forestry and on hard surfaces.

Product details

Ecoplug Max is a plug treatment for tree stumps that releases glyphosate into the stumps to minimise root and stump sprouting.

Product details

Icade quickly translocate throughout the target plant and is effective against a wide range of tough and invasive weeds - including Japanese knotweed, Hogweed and Buddleia.

Product details

LockStar is a total herbicide for the pre-emergence and early post-emergence control of annual and perennial weeds on natural surfaces not intended to bear vegetation, permeable surfaces overlying soil, and hard surfaces (railway ballast only).

Product details

The quality of the water used in spray solutions can have a signiﬁcant impact on the performance of the pesticide or foliar nutrition being used. NupHix is a specialist water conditioner that adjusts spray tank water to an optimum pH level of 4.0 - 5.0. NupHix contains chemical water conditioners that dissolve the carbonates in the spray solution to reduce their ability to react with pesticides or foliar feeds. NupHix also contains an indicator dye which turns pink when the water has achieved the ideal pH range.

Product details

Roundup ProActive is a foliar applied translocated herbicide for the control of annual and perennial grass and broad-leaved weeds.

Product details

Roundup ProVantage is a foliar applied translocated herbicide for the control of emerged weeds in industrial and amenity situations, in grassland, orchards, forestry and in aquatic areas.

Product details

Speedway Total is a spray adjuvant that contains a blend of surfactants and spreaders. It is designed to enhance the effect of glyphosate and other total and/ or non-selective herbicide treatments. Speedway Total assists herbicide penetration into the leaf cuticle by dissolving the waxy leaf coating. The surfactants and spreaders also aid the treatment spreading properties, reduce the risk of wash-off and increase the herbicidal uptake.

Product details

Synero is designed for the control of a wide range of deep rooted perennial and herbaceous weeds on non-crop land such as motorway and railway embankments, roadsides, grassland of no agricultural interest and industrial areas (excluding airfields). Synero quickly and effectively combats invasive, difficult-to-kill weeds, and is ideal to use as part of an vegetation management programme.
