Row Crop Flaming FAQs


What is the average fuel consumption per acre?

You can expect an average of 5 gallons or 19 liters per acre.

How fast can I travel while flaming?

Around 3-5 miles per hour.

How does flaming kill the weeds but not hurt the crop plant?

As long as the weeds are smaller than the crop, flaming will kill weeds without damaging the crop. The flames from the staggered torches are directed under the crop leaves and through the crop row. The flame will not affect the hearty stalks but will apply intense heat to the weed leaves and grass in the row causing damage to cell structure. This in turn destroys the photosynthesis process which kills the weeds.

How many times will I have to flame?

Once or twice is common, but it varies depending upon weed pressure and field conditions. We recommend flaming before planting to kill weeds and weed seeds. Many crops can be flamed a second time when the crop emerges as a flush of weeds emerge at the same time. The crops like corn, soybeans, sunflowers and tomatoes can be flamed a third time if needed when the crop is tall enough to flame under the canopy of leaves.
