Thermal weeding

UK farmers and growers are to be first to benefit from an innovative weeding technology that is said to provide a cost-effective, natural alternative to time-consuming weeding for high-value crops.

Designed and manufactured in the UK by Weeding Technologies, the AW Series, powered by Foamstream, was developed in response to increasing legislation. It combines thermal weeding technology and precision engineering.

Precision nozzles apply at a rate of up to 10 litres per minute with tractor speed typically around 3kmph. Tank capacity is 600 litres - an hour's use. Cost savings for the horticultural grower average 33 per cent compared with traditional weeding methods and there are significantly reduced carbon dioxide emissions.

Foamstream employs a mix of boiling water, steam and a foaming agent derived from natural ingredients. It is designed to treat all types of weeds, the steam transferring the heat to the plant cells and the foam acting as a thermal blanket to prevent heat loss. The cells are heated to the point where they rupture and the plant dies.
