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...

HIGHLIGHTS Trichoderma inoculation increased the total biomass, seedling height, root length, area, diameter, number of tips, and growth potential seedlings. increases resistance bean plant to Rhizoctonia pathogen. Among improved isolates Trichoderma, ChBD13 ChBD15 showed better performance in terms growth.

in vitro antifungal activity of silver nanoparticles, at concentrations of 6, 8, 10, 12, 14 and 16 ppm, was studied on five phytopathogenic fungi, and a biocontrol agent. then effect of silver nanoparticle at 6 ppm (optimum concentration) was evaluated on macrophomina phaseolina in greenhouse. for in vitro experiment, the fungal isolates were grown on potato dextrose agar medium amended with si...

Here we present a metabolic profiling strategy employing direct infusion Orbitrap mass spectrometry (MS) and gas chromatography-mass spectrometry (GC/MS) for the monitoring of soybean's (Glycine max L.) global metabolism regulation in response to Rhizoctonia solani infection in a time-course. Key elements in the approach are the construction of a comprehensive metabolite library for soybean, wh...

ABSTRACT Systematic studies were conducted to elucidate the role of different soil microbial groups in the development of apple replant disease. Populations of targeted microorganisms were reduced by the application of semiselective biocides and soil pasteurization. Bacteria were not implicated in the disease, because application of the antibiotic chloramphenicol reduced soil populations of bac...
