Dr Kioumars Ghamkhar: AgResearch expert on the new Map and Zap technology that kills weeds with AI - The Sunday Session with Francesca Rudkin

New technology using AI and lasers is helping growers to safely tackle weeds without resorting to harmful chemicals.

Map and Zap detects weeds and kills them with a laser - leaving no chemical residue in the soil and not releasing additional carbon.

AgResearch expert Dr Kioumars Ghamkhar says the trials have been successful so far.

"In vineyards, you don't kill all weeds. You want to keep clover, for instance, because it fixes nitrogen and it's good for the soil. That gave us the option to kill other weeds... but clovers were kept alive."
