Company chief executive officer Leo de Montaignac, told Horticulture Week that concerns over pesticides' health effects is prompting "progressive" companies to invest in the technology.
The increased interest also coincides with the publication this year of the UK's first integrated pest management guidance for amenity use - Weeds: Best Practice Guidance Notes for Integrated & Non-chemical Amenity Hard Surface Weed Control - which suggests how the industry can use fewer chemicals (HW, 17 April).
Quadron Services, for example, is using the foam-based product as part of its contract with the London Borough of Southwark.
De Montaignac said: "Southwark has had a lot of success using it in their parks and Quadron is considering using it for other councils it works with, such as Kensington & Chelsea and Medway."
He added that two national organisations in the landscaping sector are looking to take the technology and the firm, which is currently carrying out demonstrations in the UK for local authorities and contractors, is also working with LanGuard.
De Montaignac admitted that, per square metre, the product costs twice as much as herbicide but said the company has been working hard at reducing costs.
"One of the key issues is that we are an industry that's brand new but it will get cheaper every year as we develop the technology."
The company has, for example, adapted its MW-Series kit so that it now uses 40 per cent less Foamstream than it did previously.
