The 2024/25 ‘Dog book’ is now available online, with hard copies coming next month.
This eBulletin summarises the major changes compared with the previous version. The CropLife Resistance management strategies for fungicides will be updated in July. This means that the current strategies have been retained for now from the 2023/24 edition, but the updated strategies will be included in the printed booklet and updated online as soon as they are available in July.
