Bad weather is stalling maize harvest throughout the UK, but a new disease – K zeae – is killing affected crops at dramatic speed. The disease has struck Jeremy Wilsons 28ha (70 acre) maize crop in Elham Valley, Kent. Worst affected areas are on the highest ground at 180m (600ft). NIAB advice to harvest as quickly as possible will be heeded by Mr Wilson as soon the rain relents. "Vegetative die-back occurred at a frightening speed; it was like spraying with Reglone or having six frosts on the trot."
