Epidemiology / Épidémiologie Spatial distribution of Rhizoctonia oryzae and rhizoctonia root rot in direct-seeded cereals
Rhizoctonia oryzae causes root rot and stunting of wheat, barley, and other small grains, and is widely distributed in eastern Washington State. The spatial distribution of both the pathogen and the disease were studied over two seasons in a 36-ha field north of Pullman, Wash. The field was direct seeded with spring barley in 2000, then divided and planted to winter wheat and spring wheat in 20...
متن کاملWide Variation in Virulence and Genetic Diversity of Binucleate Rhizoctonia Isolates Associated with Root Rot of Strawberry in Western Australia
Strawberry (Fragaria×ananassa) is one of the most important berry crops in the world. Root rot of strawberry caused by Rhizoctonia spp. is a serious threat to commercial strawberry production worldwide. However, there is no information on the genetic diversity and phylogenetic status of Rhizoctonia spp. associated with root rot of strawberry in Australia. To address this, a total of 96 Rhizocto...
متن کاملnew anastomosis group f (ag-f) of binucleate rhizoctonia causing root and stem rot of pistacia vera
a total of ten isolates of fungi with rhizoctonia-like mycelia were obtained from infected roots and stems of pistachio pistacia vera grown in a commercial nursery in rafsanjan, iran, during the autumn of 2011. the infected seedlings showed symptoms of chlorosis that later turned to necrosis. all of the isolates were identified as binucleate rhizoctonia on the basis of hyphal characteristics an...
متن کاملLeuconostoc spp. Associated with Root Rot in Sugar Beet and Their Interaction with Rhizoctonia solani.
Rhizoctonia root and crown rot is an important disease problem in sugar beet caused by Rhizoctonia solani and also shown to be associated with Leuconostoc spp. Initial Leuconostoc studies were conducted with only a few isolates and the relationship of Leuconostoc with R. solani is poorly understood; therefore, a more thorough investigation was conducted. In total, 203 Leuconostoc isolates were ...
متن کاملEffect of inoculum density and soil tillage on the development and severity of rhizoctonia root rot.
Rhizoctonia spp. cause substantial yield losses in direct-seeded cereal crops compared with conventional tillage. To investigate the mechanisms behind this increased disease, soils from tilled or direct-seeded fields were inoculated with Rhizoctonia spp. at population densities from 0.8 to 250 propagules per gram and planted with barley (Hordeum vulgare). The incidence and severity of disease d...
