Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Guatemala

EFSA Journal, Volume 22, Issue 1, January 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both, regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Guatemala.
