Why does identification of species matter?
- Winter wild-oat is generally considered the more challenging species to control, requiring more robust strategies
- Seedling emergence patterns and winter hardiness differ between the two species so correct identification can help determine the best herbicide timing and non-chemical control strategy.
- Although herbicide resistance has been found in both species, it is relatively more common in winter wild-oat – the first cases of resistance in the UK were all found in this species.
A separate two-page detailed identification guide has been produced recently.
