A previously undescribed leaf spot of pepper (Capsicum annuum) in the Sultanate of Oman was found to be caused by Cladosporium oxysporum. Symptoms included irregular, brown leaf spots, 1–4 mm in diameter. The causal fungus was isolated and shown to be pathogenic by inoculation of attached and detached leaves of pepper under controlled conditions. Most cultivars tested were susceptible to the new leaf spot.
