utility of fungicides for controlling rhizoctonia solani on sugar beet
rhizoctonia solani is the most serious problem on sugar beet beta vulgaris l. grown in north dakota and minnesota. picoxystrobin, a quinone outside inhibitor, and penthiopyrad, a succinate dehydrogenase inhibitor, were used alone and in combinations for controlling r. solani ag 2-2 iiib on sugar beet under greenhouse conditions of 22 ± 2 °c and a 12-h photoperiod. fungicides were applied in-fur...
متن کاملEvaluation of yield potential and resistance to rhizoctonia (Rhizoctonia solani) disease of new sugar beet (Beta vulgaris L.) hybrids
Rhizoctonia root rot disease is considered as one of the important diseases in sugar beet. Using resistant cultivars decreses production costs, especially application of fungicides and increases the efficiency in controlling of root rot disease. Therefore, growing of resistant cultivars is considered the best approach for disease control. To achieve this goal and to determine yield potential of...
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 کاملNuclear magnetic resonance: a tool for imaging belowground damage caused by Heterodera schachtii and Rhizoctonia solani on sugar beet
Belowground symptoms of sugar beet caused by the beet cyst nematode (BCN) Heterodera schachtii include the development of compensatory secondary roots and beet deformity, which, thus far, could only be assessed by destructively removing the entire root systems from the soil. Similarly, the symptoms of Rhizoctonia crown and root rot (RCRR) caused by infections of the soil-borne basidiomycete Rhi...
