Isolation and Characterization Plant Pathogenic Fungi of Citrus Plant

Citrus plants are one of the essential crops that have a high demand in industrial commerce, especially in the Mediterranean climatic region and East Asia, including Malaysia. It has the pros and cons of profit-making citrus products as it has limited commercial field in some countries due to the less efficiency of conventional plant stock production methods. Malaysia is one of the countries affected as it has less production of citrus plants and causing our country to import more citrus products from other regions which costs twice compared to self-production market price. This is because one of the constraints faced by us is diseases that infect citrus plants that are caused by pathogenic fungus. The goal of this research is to isolate and characterize pathogenic fungus from Citrus aurantifolia and Citrus limon. Pathogenic fungi were isolated from infected plant tissue by culturing it on agar media. The pathogenicity of the isolated pure culture was tested, and the expected result which are several different pathogenic fungi of Citrus were isolated and characterize upon successful completion of this study. As a result, various types of plant pathogens are found after being categorized by experimental techniques in the laboratory
