While attempts to control weeds in row crops using flaming alone normally have resulted m lower yields than when weeds were controlled by mechanical and/ or chemical methods, this probably was due both to thermal damage to the crops and to inadequate weed control. The specific objectives of this project were to determine:

• If the air-curtain method of flaming improves on previous flaming techniques

• If flaming as the principal means of weed control needs supplementary weed control measures

• If flaming gives better weed control than conventional chemical methods.
