Conteúdo: |
Wilting and crown-rot symptoms were observed in sweet pepper (Capsicum an-nuum) plants in field surveys carried out in 2021 across major vegetable-producing areas of three municipalities of Guatemala. Phytophthora capsici (Peronosporales, Peronosporaceae) isolates were identified in association with these symptoms based upon morphological and phylogenetic analyses using nucleotide sequence informa-tion of the Cox2 mitochondrial DNA (mtDNA) region. Biological tests confirmed P. capsici mating type A1 isolates as the causal agents of the disease. Symptoms similar to those observed in the field were obtained after controlled inoculation of C. annuum‘Tico’ seedlings. Solanum habrochaites ‘LA 404’ and C. annuum ‘Crioll de Morelos’displayed strong resistance reaction against all Guatemalan isolates. Even though P. capsici is a cosmopolitan pathogen, this is the first molecular confirmation of this path-ogen infecting C. annuum in Guatemala. |
