About
The Nebraska Flame Weeding Workshop will present results from 15+ years of research conducted by the teams of Stevan Knezevic, professor of agronomy and horticulture specializing in weed science, and George Gogos, professor of mechanical engineering. This work is also documented in over 20 scientific publications, 100+ abstracts presented at many regional, national and international meetings, and a patent for flaming equipment.
Participants will learn how to properly flame all major Midwestern weeds in eight agronomic crops – field corn, sweet corn, popcorn, soybean, sorghum, alfalfa, sunflower and wheat.
Propane fueled flame weeding is an acceptable method for weed and pest control in organic farming. It is also gaining interest among conventional producers due to the increase in weed resistance and costs of GMO crop seeds.
Propane doses for weed control and crop tolerance data will be presented. Four row flamers with patented hoods for broadcast and banded flaming will be demonstrated along with flaming treatments applied at several crop growth stages in corn and soybean.
Several local organic farmers will share their experience with flame weeding on their farms.
