Description of Challenge
To replace herbicides with a safer natural method of weed controlUnwanted plants are eradicated with hot water blanketed with a natural foam
Solution
Botanists have known for a long time that boiling water kills weeds. The problem with making thermal technology available on a commercial basis has been finding a way to keep the heat on the plant long enough to kill it. Hot water alone doesn’t work well enough.
Foamstream, a biodegradable foam made from natural and renewable plant oils and sugars can be precisely applied to weeds with hot water and the combination effectively eradicates weeds.
Heat is applied to the weed in the form of foam and hot water
The foam acts as a blanket, keeping the heat on the weed long enough to kill it
A wetting agent in the foam speeds up the transfer of heat into the weed’s cell walls
The weed dies within minutes
Repeated applications can reach tap roots where their eradication is required
