Abstract
⺠Overall response to flaming varied among species, growth stage and propane dose ⺠Broadleaf weeds were more susceptible to flaming than the grass regardless of the growth stage ⺠The tolerance of both grassy and broadleaf weed species to broadcast flaming increased with increase in plant size ⺠A dose of 76 kg/ha of propane was needed to obtain 90%\ dry matter reduction for 7-leaf (L) barnyardgrass compared to much lower doses of 40, 49, 55, 56 and 51 kg/ha propane for 8-L bindweed, 6-L kochia, 10-L morning glory, 7-L velvetleaf and 5-L Venice mallow, respectively ⺠Broadcast flaming has potential for control or suppression of weeds in organic farming.
