Abstract

Abstract
Brown rot is one of the fungal disease in the north of Iran. Symptoms on infected fruit in the initiation of infection appear as small dusky spots resembling peteca. Then infected tissues were removed and cultured on the PARPH selective medium. Based on morphological characters, growth rates, growth patterns and cardinal temperatures for growth, P. parasitica as a causal agent for mandarin varieties and P. citrophhtora for sweet oranges were identified. In pathogenicity test Phytophthora spices (P. parasitica and P. citrophthora) respectively on fruit of mandarin varieties and sweet orange were found to be pathogenic.
