Efficacy of Hydrogen Peroxide on Root Rot Disease of Ginseng Sprouts

Abstract

Hydrogen peroxide is an eco-friendly oxidizing agent, which has exhibited a broad spectrum of antimicrobial activity without adverse environmental impact. This study was conducted to investigate the antifungal effect of hydrogen peroxide treatment against <i>Cylindrocarpon destructans</i>, and consequently to evaluate its control efficacy against root rot disease of 2-year-old ginseng plants. Hydrogen peroxide treatment strongly inhibited the viability of <i>C. destructans</i> conidia <i>in vitro</i>. The hydrogen peroxide at a concentration of 300 mg/l significantly reduced disease infection of the ginseng root when treated to spore suspension (10<sup>7</sup> conidia/ml). Spraying with 300 mg/l of hydrogen peroxide reduced the root rot disease of the ginseng sprouts by 15% compared to the untreated control at 14 days after the inoculation. However, 300 mg/l of hydrogen peroxide delayed the emergence of ginseng plants during sprouting under aeroponic conditions. Further works need to be done to provide an acceptable control efficacy of hydrogen peroxide against the disease and its good safety to ginseng plants.

A Comparative Analysis of Microbial Communities in the Rhizosphere Soil and Plant Roots of Healthy and Diseased Yuanyang Nanqi (Panax vietnamensis) with Root Rot

“…Meanwhile, in the root community, the bacterial genera unidentified_Cyanobacteria, Pseudomonas, Serratia, etc., constitute the largest proportion of the root communities, of which Pseudomonas is the dominant bacterial genus. Among the fungal genera, Fusarium, Saitozyma, Mortierella, Cylindrocarpon, Pseudosigmoidea, and Gibberella make up the largest proportion; Fusarium is the dominant fungal genus in the rhizosphere community, which is basically consistent with studies of the root communities of other ginseng plants [49][50][51][52]. This shows that the strains of these two genera have a greater impact on ginseng root rot.…”
