RESUMO:

Rust fungi are among the most destructive plant pathogens worldwide, and their management still relies heavily on chemical fungicides. Hyperparasitic fungi offer a promising, environmentally sustainable alternative, yet their diversity, ecology, and functional roles remain underexplored. This review synthesizes current knowledge on rust-associated hyperparasites, highlighting key biocontrol candidates in genera such as Sphaerellopsis, Cladosporium, Akanthomyces, and Simplicillium. By reducing pathogen virulence, survival, sporulation, viability, and dispersal, hyperparasites shape disease dynamics across natural and agricultural ecosystems. Despite numerous reports of rust-associated hyperparasites, major knowledge gaps persist regarding their true diversity, mechanisms of interaction, host specificity, and ecological significance. Recent advances in molecular taxonomy and high-throughput sequencing are expanding our understanding of rust-associated fungal diversity, revealing previously overlooked taxa and complex multitrophic interactions. However, practical application of hyperparasitic fungi remains constrained by challenges in isolation, identification, host specificity, environmental dependence, variable field performance, mass production, formulation, and regulatory approval. Consequently, commercial hyperparasite-based products remain scarce. We argue that integrating ecological, taxonomic, molecular, and biotechnological frameworks is essential to fully harness these organisms for rust disease management. Driven by the demand for sustainable agriculture and biotechnological progress, hyperparasitic fungi can become key components of integrated disease management, natural regulating rust pathogen populations to support resilient agroecosystems.
