Rust fungi, part of the Basidiomycota phylum, are crucial plant pathogens affecting crops globally. With over 7,000 species, they exhibit complex life cycles involving up to five spore stages and often require two different hosts. Management strategies include crop rotation, resistant varieties, and fungicides. Understanding these fungi is vital for crop protection and ecological balance.
