An organic farmer says genetically modified grasses should not be considered as a weapon to help farmers fight drought.
Agricultural organisations in New Zealand are researching drought tolerant GE ryegrasses and conducting field trials overseas.
Glenn Mead runs a 260 hectare sheep and beef farm in South Otago and is chair of the Organic Dairy and Pastoral Group.
Mr Mead believes the GE grasses should not be introduced here because, he says, there is a lack of independent research into the technologies, and export markets don't want them.
He said the lack of independent research on genetically modified crops and grasses means their potential effects on humans and stock are unkown.
Mr Mead said farmers should be thinking about the many natural options they can take to future-proof their land from drought, such as introducing a larger mix of grassland species and herbs, and planting more trees.
