Comparison of soil-pellet and sieving-floatation methods for enumeration of sugarbeet-root-rot fungus (Rhizoctonia solani AG 2-2).

Molecular 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...

Registration of Four Multigerm Sugarbeet Germplasms Resistant to Rhizoctonia Root Rot: FC716, FC717, FC718, and FC719

Sugarbeet (Beta vulgaris L.) germplasms FC716 through FC719 (Reg. no. GP-143 to GP-146, P1 574627 to P1574630) were developed by the USD A-ARS in cooperation with the Beet Sugar Development Foundation. Each of these germplasms was developed from genetically different and distinctive sources. These lines should provide resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kilhn and p...

Unconventional alternatives for control of tomato root rot caused by Rhizoctonia solani under greenhouse conditions

This study was done to assess the antifungal effect of some biocontrol agents effective microorganisms (EMs1), Pseudomonas fluorescens, and Bacillus pumilus, titanium dioxide (TiO2) nanoparticles, black cumin and wheat germ oils as well as the recommended fungicide (flutolanil) against root rot of tomato. Moreover, gas chromatography-mass spectrometry (GC-MS) examination was completed to identi...

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
