| Components of resistance were evaluated in seven Musa genotypes artificially inoculated with mycelia fragment suspensions of Mycosphaerella fijiensis Morelet (strain CCIBP-Pf80). Incubation period, number and area of necrotic lesions, infection index, area under the disease progress curve, asexual latent period, and number of spermogonia were evaluated in the genotype leaves to dissect the infective cycle of the fungus under greenhouse conditions. Incubation period in the inoculated leaves began at 14-21 days post infection, and significant differences were detected in the response of the different genotypes. Necrotic lesions were only observed in Grande naine, Pisang Awak, and significantly less in Pisang lilin. Grande naine reached the highest percentage... |

| O uso de fungicidas sintéticos é uma das estratégias de manejo de doenças mais utilizadas na agricultura, porém, busca-se manejos que sejam mais sustentáveis. Dessa forma, objetivou-se avaliar o potencial de óleos essenciais de Cedrela fissilis e Mentha spicata no controle, in vitro, do crescimento micelial do patógeno Corynespora cassiicola. O trabalho foi desenvolvido no Laboratório de Fitossanidade da Universidade Estadual do Mato Grosso do Sul (UEMS), Unidade Universitária de Cassilândia-MS. Os óleos essenciais, Cedro (Cedrela fissilis) e Hortelã (Mentha spicata) foram adquiridos comercialmente. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 2 categorias de óleos essenciais (hortelã e cedro) x 5 concentrações... |

| ABSTRACT This study presents the description of Phaeosphaeria deschampsii, which was found in plant communities from Half Moon Island, South Shetland Archipelago, Antarctica, in February 2014. Many patches of Deschampsia antarctica (Poaceae), the only indigenous Poaceae specie in Antarctic, were found dead, parasitized by a fungi pathogen. Based on the shape of its perithecia, with oblique neck, erumpent in the grass tissues, ascospore form and septation, the specie was identified as new to science. |

| ABSTRACT tenocarpella maydis is one of the main fungi associated with maize seeds, being a causative agent of stalk and ear rot, a disease which causes considerable losses for crop-producing regions in Brazil. The organism is considered to be a pest, subject to sanitary standardisation in current programs of seed certification in the country. The aim of this study was to evaluate the transmission rate of the fungus from infected maize seeds. Seeds were inoculated with two isolates using a method of physiological conditioning, in which the seeds are kept in contact with colonies of the fungus for 24 (P1), 48 (P2), 72 (P3) and 96 (P4) hours. Two cultivars were used, one susceptible (C1) and one moderately resistant (C2), and the trial carried out at two... |
