As interest in organic agriculture grows, so does the popularity of flame weeding. By using intense heat to rupture the plant cells, weeds wither and die. This environmentally-friendly practice can replace traditional herbicide applications, and according to the Organic Farming Research Foundation, can be just as effective. Here are a few reasons farmers are using propane for weed control:
Versatile & flexible
- Flame weed control can be practiced in a variety of growth stages and weather conditions – even on a windy day or when the soil is wet.
- Flame weeding allows producers to return to the field immediately after treatment as it does not leave chemical residues.
- Flame weeding more than doubles the level of weed control obtained using only cultivation.
Sustainable & affordable
- Flame weed control does not damage soil microbes, reduce tillage, or cause moisture loss.
- With the low cost of propane, flame weed control is a financially competitive alternative to using herbicides.
- Flame weeding uses 4-10 gallons of propane per acre per treatment. Most producers who use this practice typically apply two treatments per year.
