| Colletotrichum lindemuthianum (teleomorfo Glomerella cingulata f. sp. phaseoli) apresenta ampla variabilidade genética, demonstrada por suas características morfológicas. Com este trabalho, objetivou-se caracterizar, por meio de marcadores morfológicos, diferentes isolados de C. lindemuthianum e identificar marcadores morfológicos com uso potencial em análises genéticas. Foram avaliados os seguintes caracteres morfológicos e culturais: cor e textura das colônias, compatibilidade vegetativa e sexual, índice de velocidade de crescimento micelial (IVCM), diâmetro colonial (DC), capacidade de esporulação (CE), dimensões e formas conidiais, dimensões dos ascósporos, formação de estruturas reprodutivas e formação de anastomoses entre hifas e conídios.

| Pseudocercospora griseola, the etiologic agent of angular leaf spot of common bean (Phaseolus vulgaris), is an important disease in all bean-producing regions worldwide and may cause extremely high yield losses. The control of this disease is made more difficult by the pathogen's genetic variability and the inefficiency of fungicides. In this study, of 26 essential oils tested at different concentrations, 25 demonstrated efficiency in affecting the germination of strains 63-31 and 63-63 of the pathogen, reaching inhibition levels of between 80% and 100%. Cymbopogon citratus and Cymbopogon martinii inhibited conidia germination at all concentrations; Eugenia caryophyllata, Cinnamomum sp., Thymus vulgaris, Matricaria recutita, Cordia verbenacea, Origanum... |

| ABSTRACT: Early blight is one of the most important fungal diseases of potato. The objective of this study was to evaluate the in vitro reaction of potato genotypes to the severity of early blight and compare the species Alternaria solani and Alternaria grandis , etiologic agents of disease, through the evaluation of physiological characteristics. Twenty-two genotypes of the Potato Breeding Program at UFLA, two cultivars, Aracy and Bintje, patterns of resistance and susceptibility, respectively were evaluated. For inoculation, three isolates of A. grandis and two isolates of A. solani were used. Plantlets obtained in vitro were inoculated with a 5mm diameter mycelial disk of isolates Alternaria spp. of. These were incubated in severity and classified... |
