19 fire crews working on it
Devon and Somerset Fire and Rescue says it has 19 fire engines on the scene of an outdoor blaze in a cornfield near Brixton in South Devon.
A combine harvester is also involved.
They say they are fighting the fire using: hose reel jets, main jets, breathing apparatus, a water bowser, multiple beaters and, as you might expect on a farm, pitchforks.
Fire crews are involved from Bovey Tracey, Brixham, Dartmouth, Kingsbridge, Moretonhampstead, Danes Castle, Crediton, Honiton, Plympton, Camels Head, Greenbank, Plymstock, Ivybridge, Princetown, Yelverton and Clyst St George.
