| A new weed-burning machine is being tested in the Esperance area to tackle herbicide resistance without using chemicals.
Herbicide resistance is one of the greatest problems continuous-cropping broadacre farmers face.
Precision Agronomics Australia this week trialled a prototype weed-burning machine, which aims to kill small weeds that have been placed in controlled traffic tramlines during harvest.
PAA agronomist Quenten Knight said the twin burners were fuelled by propane gas and reached a temperature of about 400C while travelling at a speed of about 3km/h to 5km/h.
A rig has been developed by PAA employee Nick Ross that can be mounted on the front or rear of tractors.
