Abstract
Aphelenchoides besseyi was detected as the causal agent of foliar dark spots on cowpea plants growing in the field, and its pathogenicity was confirmed. The identity of the nematode was determined through morphological, morphometric, and molecular characterization, using species-specific primers Abess_11F/Abess_11R targeting 28S rDNA, which amplified a fragment of 570 bp. This is the first report of A. besseyi parasitizing cowpea under field conditions in Brazil.
期刊介绍：
Australasian Plant Disease Notes is an international journal for publication of short reports from all countries which describe original research that transcends national boundaries. All aspects of plant pathology are covered including new geographical records of diseases or pathogens, new pathogens or pathogen strains, taxonomic papers, quarantine notes, disease management and diagnostic methods. Australasian Plant Disease Notes is a publication of the Australasian Plant Pathology Society.
