Abstract Myrtle rust (MR) caused by Austropuccinia psidii is one of the most important diseases affecting eucalypt ( Eucalyptus ) plantations in Brazil. Over years, selection and planting MR‐resistant clones has been primary strategy for MR management. In May 2013, young trees GG100 hybrid E . grandis × E. urophylla clone—widely planted Brazil previously classified as resistant to MR—were infected A. Minas Gerais, this study, artificial inoculations a clone set with differential reactions...
Abstract Teratosphaeria nubilosa is the predominant causal agent of leaf disease (TLD) in experimental plantations E. globulus Brazil. It exhibits slow vegetative growth and lack sporulation vitro culture, making it difficult to obtain enough ascospores for mass inoculation. This study aimed establish an inoculation method based on ascospore ejection from naturally infected leaves use assess response T. eucalypt species interspecific hybrids. First, optimal temperature incubation time were...
Abstract In April 2019, Samanea tubulosa seedlings were observed with typical anthracnose symptoms in a forest nursery São João Evangelista, Minas Gerais, Brazil. Based on morphological characteristics and phylogenetic analyses of ITS (5.8 S ribosomal RNA the flanking internal transcribed spacer regions), act (actin), cal (calmodulin) gapdh (glyceraldehyde‐3‐phosphate dehydrogenase) sequences, fungus was identified as Colletotrichum karstii . Inoculation healthy showed similar to those under...
Schinus terebinthifolia Raddi, popularly known in Brazil as pink pepper or aroeira, has become a new source of agricultural exploitation for some farmers, notably located the north state Espírito Santo, largest producing region world. Once it was species that been historically exploited an extractive manner, where only what nature offers is explored, need generation scientific knowledge to understand its genetic potential all agronomic areas evident, starting with large spread scale this...
