attributes.value: Pathogens were isolated from the collected samples using a conventional tissue isolation method [16]. For each sample, approximately 5 x 5 x 5 mm segments of peel-containing root tissue and an equivalent volume of internal tissue were excised. The segments were surface-sterilized by immersion in a 10% sodium hypochlorite solution for 60 s, followed by immersion in 75% ethanol for 30 s, and subsequently rinsed three times with sterile water. The treated segments were then placed on Potato Dextrose Agar (PDA) medium and incubated at 25 degrees Celsius.
