Twenty-eight potential biocontrol organisms were tested for efficacy against Rhizoctonia solani on potato in a series of greenhouse trials. Organisms tested consisted of field isolates of Paenibacillus polymyxa, Pseudomonas fluorescens, Penicillium sp., Trichoderma sp., and Rhizoctonia zeae; known biocontrol isolates including Laetisaria arvalis, Verticillium biguttatum, Cladorrhinum foecundiss...

In August 2021, we surveyed diseases of wild vegetables grown in Taebaek, Gangwon Province, Korea. During the disease survey, observed severe damping-off symptoms young edible aster (<i>Aster scaber</i>) plants a vinyl greenhouse investigated. The incidence ranged from 5% to 20%. Diseased were collected greenhouse, and fungi isolated petiole lesions diseased plants. <i>Rhizoct...

Rhizoctonia solani causes economically important root and hypocotyl diseases in common bean throughout the world. Root health is a vital factor in plant development and root diseases would negatively influence water and nutrient uptake as well as cause direct stand reduction and root rot damage to the crop. An efficient common bean screening method to evaluate damping-off and early root/ hypoco...

Although many Plant growth promoting rhizobacteria (PGPR) are used commercially, there is a need to explore more biocontrol agents combat various pathogens and sustain the productivity of crops. PGPRs inhabit rhizosphere region plant effective in managing pathogens. In this study, twenty-six PGPR isolates were screened in-vitro against fungal phytopathogens Bacteriological Laboratory, Departmen...

cyanobacteria have been considered due to producuction of types of secondary metabolites and antimicrobial compounds. this research designated for optimization of bg11 culture medium to increase the antifungal activity of cyanobacterium sp. pgu1 against the plant pathogenic fungi, fusarium oxysporum f. sp lycopersici and rhizoctonia solaniag2-2-iiib. cyanobacterium was isolated from the persian...

This study tests the effect of glyphosate application on disease severity in glyphosate-resistant sugar beet, and examines whether the increase in disease is fungal or plant mediated. In greenhouse studies of glyphosate-resistant sugar beet, increased disease severity was observed following glyphosate application and inoculation with certain isolates of Rhizoctonia solani Kuhn and Fusarium oxys...

The present work was carried out to study the potential of plant rhizosphere associated bacteria for the biocontrol of potato black scurf disease caused by Rhizoctonia solani Khun AG-3. A total of twenty-eight bacteria isolated from diseased and healthy potato plants grown in the soil of Naran and Faisalabad, Pakistan were evaluated for their antagonistic potential. Nine bacterial strains were ...
