“…Sclerotium rolfsii is isolated from symptoms collected from the entire survey area using the tissue segmentation method, or sclerotia is picked from the symptom and cultured on a Petri plate containing PDA medium (Table.1). Rashmi et al (2017) reported that S. rolfsii infected symptoms collected from the field and that the pathogen was isolated by (tissue segmentation method) a small piece of the diseased portion placed in a PDA medium containing a Petri plate. And also, Chandra Sekhar et al (2017b) reported that S. rolfsii was isolated from the small tissue of an infected stem or roots on a PDA medium amended Petri plate.…”

Sclerotium rolfsii is a highly threatening pathogen,affecting more than 500 hosts worldwide. In the present study, ten different isolates of Sclerotium rolfsii were isolated from groundnut growing regions of Tamil Nadu, and their morphological characteristics were observed on potato dextrose agar (PDA) medium. The virulent isolate SR-8 produced pure white with thin mycelia growth, very fast growing mycelium, dark brown colored sclerotia, and the highest number of sclerotia /plate (538). The pathogenicity test was conducted on pot-cultured, grown groundnut plants. The virulent isolate SR-8, S. rolfsii, is infected at various stages of its growth and development in groundnut plants. Lipid peroxidation and pathogenicity are crucial to identify the virulent nature of the pathogen. The pathogenicity of the virulent isolate SR-8 that produced the highest disease incidence was 89.29 % and had a high amount of lipid peroxidation of 0.9589 μmol/g. The least virulent isolates produced the minimum amount of lipid peroxidation and disease incidence. All the ten isolates exhibited different cultural and morphological characteristics, lipid peroxidation rates, and various levels of disease incidence on groundnut.

“…In Tamil Nadu,major groundnut cultivating districts are Tiruvannamalai, Cuddalore, Kallakurichy, Villupuram, Vellore, Kanchipuram, Ariyalur, Thanjavur, Salem and Dharmapuri. Groundnut kernel is rich source of energy (567 calories per 100g), because of its oil content (44-48%), protein content (25-36%) and contain health benefiting nutrients, minerals, antioxidants and vitamins that are essential for growth and development (Rashmi et al, 2017). The groundnut roots are secreted the flavonoid compounds that increase the growth of symbiotic and non-symbiotic nitrogen fixing bacteria, root nodules and nitrogen uptake by plants (Solaiman et al, 2014).…”

Groundnut or peanut (Arachis hypogea L.) is an important oilseed and edible crops of the world. It is affected by many diseases, among which stem rot disease caused by Sclerotium rolfsii is major fungal disease that cause severe yield losses up to 80%. An experiment wasconducted in Tamil Nadu during 2019-2020, to study the cultural, morphological and pathogenicity of different isolates of S. rolfsii infecting groundnut in major cultivating areas of Tamil Nadu. The overall disease severity ranges from 9.82 to 36.83 percent. The highest disease incidence 36.83 per cent was noticed in the Kalpadai village and the least incidence 9.82 per cent was recorded in Pattukotttai village. All the isolates varied their ability to produce abundant mycelium and sclerotial production. The pathogenicity test was conducted to all the twenty isolates and the isolate Sr6 exhibited the maximum disease incidence and proved to be more virulent.
