Flame weeding - Farmers using propane-gas flame weeders have reported higher yields per acre by using propane.
Pest control - Propane gas flamers can provide 70 percent to 90 percent control of wintering adult insects compared with 25 percent to 50 percent provided by chemical pesticides, and propane flamers cost three to five times less per acre than chemical controls.
Crop drying - Propane drying systems are widely used because of the simplicity of the required equipment, which contributes to low equipment, fuel and maintenance costs.
 Crop heating - Propane heaters operate efficiently for long periods while producing enough heat to prevent valuable crops from being ruined by unexpected cold spells. Propane is also used in heating greenhouses.
Dairy Heating - For barn and home applications-commercial water heat
Studies show that tractors fueled by propane can have lower major overhaul costs than gasoline-powered tractors, and sometimes, engine life is prolonged.
Some gasoline-powered tractors that are converted to propane have an increase in power. In a properly modified engine, farmers report the ability to pull larger equipment than before, because propane has a much higher octane rating than gasoline.
