Identification and potential of the hyperparasite Acremonium persicinum as biocontrol agent against coffee leaf rust

Coffee farmers face major losses from rust disease, and traditional fungicide treatments have become less effective over time. Scientists in China discovered a microscopic fungus called Acremonium persicinum that naturally attacks and kills coffee rust pathogens. Laboratory tests showed this beneficial fungus could eliminate over 90% of rust spores and completely prevent rust infection on coffee leaves, offering a natural and environmentally-friendly solution for protecting coffee crops.

Scientists discovered 16 different species of Trichoderma fungi living in coffee plants and on coffee rust fungus in Africa, including four previously unknown species. These beneficial fungi show promise as natural pest controllers for coffee leaf rust, a major disease threatening coffee production worldwide. Interestingly, the same fungi were not found in coffee plants surveyed in Brazil, suggesting they may be unique to African coffee populations. This discovery could help farmers control this destructive disease without chemicals.
