Alternaria dauci causes leaf spots and leaf blight of coriander (Coriandrum sativum) in Brazil

Abstract

Alternaria dauci is fully confirmed to cause leaf spots and leaf blight of coriander (Coriandrum sativum) in Brazil based on observations made of blighted plants at a demonstration plot (Infectarium) at Viçosa (state of Minas Gerais) Brazil. Identification was supported by a combination of morphological, cultural and molecular features. A representative herbarium sample and an isolate were deposited in public collections as well as DNA sequences. Pathogenicity tests were conducted and Koch’s postulates were fulfilled.
