Andrew Griffiths is leading work identifying genetic markers of herbicide resistance. The broad aim is developing tests that allow the quick assessment of weed tissue that shows a plant is resistant to herbicide.

Currently plants are gown to maturity, seeds harvested, sown, grown and treated with varting rates of herbicides. This is a slow and costly process. The genetic marker tests could give answers in days.

Andrew is a Senior Scientist at AgResearch where he has worked extensively on forage improvement, including researching the genetics of grasses and clovers.
