Rhizoctonia blight is a common and serious disease of many turfgrass species. The most widespread causal agent, Thanatephorus cucumeris (anamorph: R. solani), consists of several genetically different subpopulations. In addition, Waitea circinata varieties zeae, oryzae and circinata (anamorph: Rhizoctonia spp.) also can cause the disease. Accurate identification of the causal pathogen is import...

Chia (Salvia hispanica L.) is one of the most important medicinal plants recently introduced to Egyptian cultivation and has significant multiusing in human curing. Fusarium oxysporum, F. roseum, semitectum, solani, Macrophomina phaseolina, Pythium ultimum, Rhizoctonia solani Sclerotinia sclerotiorum were isolated from infected plants, showing root stem rot symptoms collected different localiti...

Field burning of residue is a traditional management tool for irrigated wheat (Triticum aestivum L.) production in the Inland Pacific Northwest of the United States (PNW) that can result in reduced air quality. A 6-year no-till field experiment to evaluate two complete cycles of a 3-year irrigated crop rotation of winter wheat–spring barley (Hordeum vulgare L.)–winter canola (Brassica napus L.)...

many fungi cause sugar beet root rot during various stages of the plant growth. among them rhizoctonia spp. induce crown rot, dry rot and violet root rot on sugar beet (whitney and duffos,1986). root rot caused by phytophthora drechsleri has been observed in fields with excessive moisture (habibi,1975). pythium aphanidermatum has been recognized as one of the causal agents of sugar beet, dampin...

The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely fungicides to protect in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied in-furrow and foliar sprays manage solani, but repeated use of QoI pose risks fungicide resistance. Penthiopyrad is a novel with the succinate dehydrogenase (SD...
