If weeds go brown immediately after treatment, this could
indicate that forward speed is too slow and excessive heat
is being applied.

In general, annual weeds are easier to kill than biennial or
perennial ones. Weed species that originate from desert or
semi-arid regions are more heat tolerant and will need a
slightly prolonged treatment period compared to other
species.
Biennial or perennial weeds usually have parts protected
against heat (especially regenerative parts under the soil,
the Rhizome). Foamstream is a contact application, it will
kill foliage but many perennial and biennial plants will
regenerate. The number of repeat treatments required to
completely kill weeds depends on the species and their size.
4.3 Caution – poisonous weeds
Some poisonous weeds, such as common ragweed ( Senecio
jacobaea) may still be attractive to animals after treatment
with Foamstream. When treating any area where animals
are likely to graze after treatment with Foamstream, check
for the presence of such potentially toxic weeds and remove
them or keep out of reach of animals that are at risk.
4.4 The effect of the system on plants
The M1200 has been designed to operate in an urban
environment and control weed growth on both hard surfaces
and cultivated land. These weeds may be in, at, or around
kerbs and channels, footpath edges, driveways, boundaries,
obstacles etc.
Within these environments there are various plant species
that need to be controlled. These species may vary in type
and growth patterns depending on the specific geographic
location.
The system, through its unique operation, delivers a plant
kill based on thermal activity penetrating and breaking down
the cell structure of the plant.
With varying plants in the target area it is important for the
operator have some knowledge of the weed types, sizes and
