The Phytophthora (Phyt) ELISA test system is specifically designed to detect the presence of Phytophthora pathogens in plant samples that display symptoms indicative of infection, such as wilting, root rot, or dieback. It is also applicable for testing fungal culture samples to confirm the presence of Phytophthora in laboratory settings. The test employs antibodies that recognize common antigens shared among Phytophthora species, allowing it to identify the genus broadly. However, it does not have the capability to differentiate between individual species within the genus, such as P. infestans or P. ramorum, which may require more specific molecular techniques like PCR for precise identification. The ELISA method offers a rapid, sensitive, and relatively straightforward approach for screening large numbers of samples, aiding in early detection and management of Phytophthora-related plant diseases.
