Olive green velvety spots on my apple leaves and fruit cracking (seb)

Olive green to dark, velvety spots on the leaves and fruit that later turn corky and cause the fruit to crack and deform are the signs of apple scab, a fungal disease that is most damaging in cool wet springs. The fungus survives the winter on fallen infected leaves, and spores released in spring rains infect the new leaves and fruit, so weather and leaf litter drive it. Confirm with your KVK, but the velvety spots leading to corky cracking are typical. The most important cultural step is to remove or break down the fallen leaves on the orchard floor in autumn or early spring, since they are the main source of next year's infection. Prune for an open airy canopy that dries quickly. Spray timing is critical and is tied to the spring infection periods, often from the green tip and pink bud stages through early fruit, using KVK-recommended protective and systemic fungicides with typical actives such as mancozeb, dodine, captan or specific scab fungicides, applied before and around rain events and rotated by mode of action to avoid resistance. Follow the label, the pre-harvest interval, and residue and MRL limits. Plan the spray calendar with your horticulture department around your spring weather, since mistimed sprays waste money.
