First report of Fusarium proliferatum causing rot of garlic bulbs in Spain

Abstract

In October of 2008, decayed garlic bulbs (Allium sativum cv. Blancomor de Vallelado) were received from a producer in Segovia, Spain. In November of 2009, similar symptoms were observed on stored bulbs (cultivars Blancomor de Vallelado and Garcua) from each of 30 municipalities in northwest Segovia and Valladolid. A minimum of one sample was collected from 12 localities. On the basis of morphological features and pathogenicity tests, the causal agent was identified as Fusarium proliferatum. F. proliferatum has been reported on garlic in the northwestern United States and Serbia. This is thought to be the first report of a Fusarium sp. in the section Liseola attacking garlic in Spain. The fungus seems to be well established on this host in Spai
