Summary
To identify the level of susceptibility of peach cultivars, it is recommended to do the observation once or twice in spring in the period when most of the cultivars are showing symptoms of curled, red-coloured leaves, before the attacked leaves start falling.
The pictures, the description and the scale in table 1 should guide users in the correct and harmonized ranking of the susceptibility level of cultivars, based on the visual assessment of percentage of leaves showing typical symptoms.

| What problem does the tool address?: | Leaf curl (Taphrina d.) is the most important challenge in organic peach & nectarine cultivation. Infested trees have a reduced photosynthesis during spring, which might result in lower productivity. |
| What solution does the tool offer?: | Based on an earlier validated protocol, the InnOBreed peach working group, including experts from various institu-tions and countries, has developed a practical guideline to assist in the identification of the onset and field evolution of this disease on cultivars. |
