| Fungal diseases in cotton (Gossypium hirsutum), such as anthracnose caused by Colletotrichum gossypii and ramulose caused by C. gossypii var. cephalosporioides, are responsible for large yield losses. These pathogens are seed borne and morphologically similar although they induce different symptoms, which can lead to misdiagnosis using the blotter testing method. The present study was carried out to assess the viability of using Amplified Fragment Length Polymorphism (AFLP) markers to differentiate these pathogens. Five isolates, for each pathogen, were classified according to pathogenicity on cotton plants, and mycelial growth morphology. Conidial suspensions were sprayed on 30-day-old cotton plants and the symptoms assessed ten and 40 days after... |

| In 2003 and 2004, 32 isolates of Colletotrichum lindemuthianum obtained from the infected plants of field-grown common bean (Phaseolus vulgaris L.) in Santa Catarina state, Brazil were analyzed based on the virulence to 12 differential cultivars of Phaseolus vulgaris L.. Thirteen distinct races were identified, six of which had not been reported previously in Santa Catarina. This is the first report of the occurrence of 67, 83,101,103,105, and 581 races of C. lindemuthianum. Race 65 was most common (34%). All the isolates were compatible to the cultivars Michelite and Mexico 222. Some isolates infected not only differential cultivar of Mesoamerican origin, but also the ones of Andean origin. |

| Value for Cultivation and Use (VCU) trials are undertaken when evaluating improved common bean (Phaseolus vulgaris L.) lines, and knowledge of agronomic and market-related traits and disease reaction is instrumental in making cultivar recommendations. This study evaluates the yield, cooking time, grain color and reaction to anthracnose (Colletotrichum lindemuthianum), Fusarium wilt (Fusarium oxysporum f. sp. phaseoli) and Curtobacterium wilt (Curtobacterium flaccumfaciens pv. flaccumfaciens) of 25 common bean genotypes derived from the main common bean breeding programs in Brazil. Seventeen VCU trials were carried out in the rainy season, dry season and winter season from 2009 to 2011 in the state of São Paulo. Analyses of grain color and cooking time were... |

| The use of antibiotics in agriculture is limited when compared to their applications in human and veterinary medicine. On the other hand, the use of antimicrobials in agriculture contributes to the drug resistance of human pathogens and has stimulated the search for new antibiotics from natural products. Essential oils have been shown to exert several biological activities including antibacterial and antifungal actions. The aim of this study was to determine the activity of 28 essential oils from medicinal plants cultivated at CPMA (Medicinal and Aromatic Plants Collection), CPQBA/UNICAMP, against Colletotrichum gloeosporioides (Penz.) Sacc., the anthracnose agent in yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deg), as well as evaluating... |

| O presente trabalho teve como objetivo avaliar o controle de doenças do mamoeiro, utilizando extratos vegetais (alho, angico e manjericão), óleos naturais (urucum e algodão), indutores de resistência (Bion®, Ecolife® e Agro-mos®) e fungicida Mancozeb/Dithane. O Experimento I consistiu-se da avaliação dos tratamentos sobre o crescimento micelial de Colletotrichum gloeosporioides, in vitro; no Experimento II, efetuou-se a inoculação artificial do fungo sobre frutos sadios de mamão e avaliou-se a severidade da podridão peduncular, por meio de escala de notas e, no Experimento III, aplicaram-se os tratamentos em mudas de mamoeiro, inoculadas artificialmente com C. gloeosporioides, avaliando-se a antracnose com escala de notas. Os resultados obtidos... |

| Control of anthracnose in green pepper involves the use of resistant varieties and/or fungicides. The selection of varieties and efficient products demands great amounts of conidia as inoculum. It is thus necessary to optimize the production of Colletotrichum gloeosporioides conidia in the laboratory, establishing the best conditions for fungus development. The present study aimed at determining the most favorable culture media, temperature, and light conditions for the production of fungus inoculum. The fungus was isolated from green pepper fruits (Capsicum annuum L.) and transferred to four culture media (PDA, oat, filtered pepper extract, and autoclaved pepper extract), under different temperatures (15, 20, 25, 30, and 35ºC) and light conditions (24h... |

| A antracnose do milho causada pelo fungo Colletotrichum graminicola é uma das principais doenças da cultura no Brasil e no mundo, atacando praticamente todas as partes da planta. Neste trabalho foi avaliada a variabilidade genética de 95 isolados monospóricos de C. graminicola, provenientes dos estados brasileiros de Goiás, Minas Gerais, Santa Catarina, São Paulo, Paraná e Rio Grande do Sul. O DNA de cada isolado foi amplificado via PCR, utilizando-se 15 primers ISSR (do inglês, inter-simpled sequence repeat) como marcadores moleculares. Os fragmentos de DNA gerados pelo PCR-ISSR foram avaliados por eletroforese em gel de agarose com a visualização da posição das bandas formadas nos géis. Do total de 15, nove primers foram selecionados em função do maior... |

| Species of Colletotrichum are considered important plant pathogens, saprobes, and endophytes on a wide range of plant hosts. Several species are well-known on citrus, either as agents of pre- or post-harvest infections, such as anthracnose, postbloom fruit drop, tear stain and stem-end rot on fruit, or as wither-tip of twigs. In this study we explored the occurrence, diversity and pathogenicity of Colletotrichum spp. associated with Citrus and allied genera in European orchards, nurseries and gardens. Surveys were carried out during 2015 and 2016 in Greece, Italy, Malta, Portugal and Spain. A total of 174 Colletotrichum strains were isolated from symptomatic leaves, fruits, petals and twigs. A multi-locus phylogeny was established based on seven genomic... |

| The activities of the enzymes chalcone synthase (CHS) and phenylalanine ammonia-lyase (PAL) were measured in leaf extracts obtained from four cultivars of the common bean (AB 136, Rio Tibagi, Carioca and Macanudo). Two stages of plant development were examined: plantlets (V2) and the onset of blooming (R6). Initially, the plants were either treated with salicylic acid or inoculated with the delta race of Colletotrichum lindemuthianum (inductive fungus) and after three days they were evaluated for enzyme activity. Afterwards, all plants were inoculated (challenged) with the virulent pathotype 33/95 of C. lindemuthianum except for the water control. Five days later, the activities of PAL and CHS were evaluated. There were significant changes in the... |

| The cultivars, AB 136 and G 2333 both resistant to Colletotrichum lindemuthianum races 69 and 453, were crossed with the cultivars Michelite and Perry Marrow (susceptible to both races), with Dark Red Kidney and Cornell 49242 (resistant to both races) and F1 and F2 generations were obtained. Plants were inoculated using a spore suspension at 1.2 x 10(6) concentration. The reaction of F1 and F2 populations showed that Dark Red Kidney, Cornell 49242 and AB 136 cultivars had the dominant genes A (Co-1), Are (Co-2) and Co-6, respectively, was conferring resistance to races 69 and 453. The segregation data obtained from F2 populations indicated that G 2333 carried two dominant resistance genes Co-5 gene and another one Co-7 for 69 and 453 races. The dominant... |
