- Pathogenicity and aggressiveness of Colletotrichum gloeosporioides isolates in ornamental pepper Neilton Antonio Fiusa Araújo Joana D ́arc Mendes Vieira Marlene da Rocha Moura Wagner Rogério Leocádio Soares Pessoa Beatriz Meireles Barguil Agrociencias anthracnose Capsicum frutescens phytopathogenic fungi Anthracnose, a disease caused by fungi of the Colletotrichum genus, affects many crops, including ornamental plants. This study aimed at evaluating the pathogenicity and aggressiveness of the Colletotrichum gloeosporioides Penz. (Sacc.) isolates Cg 1 (papaya), Cg 2 (guava) and Cg 3 (mango) in the ornamental pepper varieties Stromboli, Etna and Pirâmide, during two different periods (July/August and November/December 2013). The fungi pathogenicity and the severity of plant symptoms were assessed using a grading scale. The three C. gloeosporioides isolates were pathogenic to the three ornamental pepper varieties studied, exhibiting different levels of aggressiveness among them. The environmental conditions influenced the isolates aggressiveness, with the most severe symptoms observed in the second assessment period. 2016 artículo científico 1517-6398 https://www.redalyc.org/articulo.oa?id=253046880013 en http://www.redalyc.org/revista.oa?id=2530 Pesquisa Agropecuária Tropical application/pdf Universidade Federal de Goiás Pesquisa Agropecuária Tropical (Brasil) Num.3 Vol.46
