Flaming as an alternative weed control method for agronomic crops in organic and conventional production

Abstract:

Organic producers are interested in testing propane flaming as part of an integrated weed management program for organic crop production. Field experiments were conducted at the Haskell Agricultural Laboratory of the University of Nebraska, Concord, NE in 2007–2008 and 2008–2009 utilizing several doses of propane applied at different plant growth stages depending on the crop and the weed species evaluated. The response of plant species to propane doses was described by log-logistic models based on visual estimates of injury and plant dry weight. Grass weed species were more tolerant than broadleaf species. A propane dose of about 76 to 85 kg/ha provided a 90% dry matter reduction at 14 days after treatment in grasses compared to 40 to 68 kg/ha broadleaf species.
