First report of Fusarium chlamydosporum causing crown rot and dumping of on Durum wheat in Algeria
Several species of Fusarium infect durum wheat plants in the eastern part of Algeria. Endophytic fungus from random wheat seeds were sampled from fifty locations in eastern Algeria and shows the existence of Fusarium chlamydosporum regarding the macroscopic and microscopic characteristics. Molecular identification using EF1 and ITS1 primers were confirmed the presence of Fusarium chlamydosporum...
متن کاملEpidemiology / 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 کاملRelative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile
G. Guzmán, B.A. Latorre, R. Torres, and W.F. Wilcox. 2007. Relative susceptibility of peach rootstocks to crown gall and Phytophthora root and crown rot in Chile. Cien. Inv. Agr. 34(1):31-40. Crown gall (Agrobacterium tumefaciens) and Phytophthora root and crown rot (PRCR), caused by P. cryptogea, are two major limiting factors affecting peach (Prunus persica) production in Chile. At present, N...
متن کاملTemperature, moisture, and fungicide effects in managing Rhizoctonia root and crown rot of sugar beet.
Rhizoctonia solani AG-2-2 is the causal agent of Rhizoctonia root and crown rot in sugar beet; however, recent increases in disease incidence and severity were grounds to reevaluate this pathosystem. To assess the capacity at which other anastomosis groups (AGs) are able to infect sugar beet, 15 AGs and intraspecific groups (ISGs) were tested for pathogenicity on resistant ('FC708 CMS') and sus...
متن کاملMolecular Characterization of Rhizoctonia Solani Ag-7 Causing Root Rot on Cotton Crop in India
Rhizoctonia solani (Kuhn) is one of the most important cotton crop pathogens. Rhizoctonia solani anastomosis groups (AGs) 7 and 4 are proven to be the most common pathogenic fungal strains on cotton crop. AG-7 can cause root rot in plants while damping-off of seedlings is most frequently attributed to AG-4. Sequencing of the ITS (Internal Transcribed Spacer) region of ribosomal DNA was performe...
