Fungal pathogens are responsible for Three major bacterial diseases and seven fungal diseases are most often seen in Ficus production. Rust: This fungal disease earned its name from the rust-orange pustules that form on the undersides of leaves.The fungus grows and spreads, upper leaf surfaces discolor, and leaves eventually fall from the plant. Many plant pathogens are fungi that cause tissue decay and eventual death of the host. Fungi live outdoors in soil and on plants and trees as well as on many indoor surfaces and on human skin. Nowadays diseases has becoming a worldwide problem and becoming highly concerning factor. While plants are naturally immune to the vast majority of potential bacterial and fungal pathogens, the few that manage to establish disease can be extremely problematic and cause economic losses. can be functionally expressed in plants to control fungal plant diseases without adverse effects on plant growth and development.
