“…Adandonon et al (2006) reported S. rolfsii as the causal organism of damping-off and stem rot diseases of cowpea, which results in the death of seedlings and yield reduction. Farooq et al (2011) and Paul et al (2021) reported S. rolfsii as the pathogen causing root rot disease in sugar beet leading to rapid collapse of the vascular tissue and death of infected plants. Le et al (2012) and Deepthi (2013) had established S. rolfsii as the inciting agent of stem rot disease in cultivated groundnut.…”

“…These enzymes in conjunction with the production of oxalic acid, an exogenous nonspecific metabolite, are important determinants of its pathogenicity status and carbohydrate metabolism (Cer & Morca, 2020). The soilborne fungus thrives in soil organic matter which increases the multiplication rate and disease development (Paul et al, 2021). Sclerotium rolfsii is difficult to control by physical and cultural practices due to its wide host range of over 500 plant species (Le et al, 2012;Yaqub & Shahzad, 2005) and production of resting spores known as sclerotia (Sennoi et al, 2010).The decay starts on the stem at above ground level with clearly visible mass of mycelium projecting into the soil organic matter and infection courts occur on the roots.…”

Sclerotium rolfsii is a soil-borne pathogen causing stem and root rot disease with concomitant reduction in growth and yield of cowpea. Therefore, this study evaluated pathogenicity of S. rolfsii isolates and the management of root and stem rot disease using Trichoderma species. The isolates were obtained from cowpea rhizosphere and pathogenicity was determined using a susceptible cowpea genotype ITI0K–815-5 in an experiment arranged in a completely randomized design with four replications. In vitro and in vivo trials of Trichoderma spp. against a selected virulent isolate Sclerotium rolfsii (SR06) were conducted in the laboratory and screenhouse, respectively. All nine S. rolfsii isolates were pathogenic to the cowpea genotype, while isolate SR 06 was the most virulent with 85.56% infectivity rate. Treatments with T. virens and T. atroviride application reduced the disease incidences to 22.2% and 25.3%, respectively, compared to synthetic funguforce fungicide. Plants that were inoculated and treated with T. atroviride had significantly higher yield of 435 kg/ha than other treatments (p<0.037). Findings from this research encourages the incorporation of Trichoderma species in the integrated management of S. rolfsii pathogen and the incidence of stem and root rot disease in cowpea.

“…The fungus produce abundant white mycelia and brown to black sclerotia near the infected portion of plant and soil surface (Mullen 2001). Warm and humid condition with a temperature ranging between 25-30°C is optimum for its growth and sclerotial germination (Punja 1985;Zape et al 2013;Paul et al 2021). Moreover, soil pH, water content, aeration, as well as soil texture in uence the growth and development of hypha and sclerotioia (Zape et al 2013, Ayed et al 2018.…”

Among the pathogen F. solani causes black root rot, R. solani causes wet root rot, however, Sclerotium rolfsii have been reported to causes mainly collar rot and to some extend root rot disease in faba bean (Singh and Singh 1990;Beniwal 1992;Kwon et al 2001;El-Mougy and Abdel-Kader 2008;Silva et al 2014;Paul et al 2021).…”

Faba bean (Vicia faba L.), a promising grain legume, widely grown in central and northern part of Bangladesh. Disease symptoms resembling to collar and root rot was observed in an experimental field of Bangladesh Agricultural University, Mymensingh, Bangladesh. Disease incidence was ranged between 11–19%. Water-soaked sunken lesions were appeared on the collar region followed by the expansion of rotten areas along with white mycelial mass. The associated pathogen was isolated and identified as Sclerotium rolfsii (Teleomorph: Athelia rolfsii) based on the morphological characteristics and sequence analysis of ITS regions. The isolates grew well in both PDA and OMA media but optimum radial growth (3.31 cm/day) was observed in PDA media. The optimum temperature and pH for radial growth were 30°C and 7.0, respectively. Host range assay revealed that S. rolfsii isolates were strongly virulent to several other important crops such as tomato, brinjal chili, pea and chick pea indicating its potential threat to future agricultural production. Although the isolates were sensitive to Amistar Top, Score and Provax fungicides but Provax was more effective to inhibit the mycelial growth of S. rolfsii at 10 ppm. To best of our knowledge, this is the first confirmed report of S. rolfsii causing collar rot of faba bean in Bangladesh and their in vitro chemical control.
