["Spring oat mildew ratings\nThe RL 2021/22 sees the spring oat mildew disease rating slope reset, using a similar approach to that described for winter wheat yellow rust (see 'winter wheat RL 2021/22'). The aim is to make the ratings more representative of what is seen in the field. This has contributed to a relatively large drop in ratings for some varieties, compared to the 2020/21 RL. This is not due changes in spring oat susceptibility to mildew or changes in the virulence of mildew."]
