Could this biodegradable foam replace glyphosate?

摘要

A foam made from plant oils and sugar is being mooted as an alternative to herbicides such as glyphosate in the battle against weeds. Lucinda Dann reports.An organic, biodegradable, alternative to glyphosate may be available to growers in the near future, as a foam-based weed solution is being developed for agricultural purposes.Foamstream uses hot water to break down a plant's waxy outer layer, allowing it to travel down the stem and kill the roots.
