English machine translation:

The disease was observed on grafted apple trees. The rootstocks were sourced from a nursery in Germany, and the grafting was carried out at a tree nursery in Germany.

The citrus concave gum associated virus (CCGaV), first described in Italy, has not yet been detected in Germany. It is not listed in the annexes of Regulation (EU) 2019/2072 or in the EPPO.
The virus infects apple and citrus trees.
It can be assumed that CCGaV can establish itself outdoors in Germany, at least in warmer regions, due to suitable climatic conditions, and that establishment in other EU member states, at least in Central and Southern Europe, is also possible.

According to current knowledge, CCGaV poses a low phytosanitary risk for Germany. For southern EU member states, the risk is probably higher, but can be significantly reduced through cultivation measures.

CCGaV is therefore not classified as a quarantine measure for organisms, Article 29 of Regulation (EU) 2016/2031 is therefore not applicable. However, it is recommended to use CCGaV-free starting material for the propagation of host plants.
