Disease: coffee leaf rust (CLR)

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

mycolabadmin

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.

Coffee leaf rust is a major disease that destroys coffee crops and costs the global coffee industry billions of dollars annually. Researchers in China discovered that a fungus called Acremonium persicinum naturally parasitizes the rust-causing fungus and can prevent coffee leaves from being infected. When this beneficial fungus was applied to infected coffee leaves, it completely stopped the rust fungus from growing and spreading. This discovery offers farmers an environmentally friendly alternative to chemical pesticides for protecting their 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.

Coffee plants are severely damaged by a fungal disease called coffee leaf rust that destroys leaves and can reduce harvests by over 70%. Scientists in China discovered a beneficial fungus called Acremonium persicinum that acts as a natural enemy to the rust-causing fungus, essentially eating and destroying it. Laboratory tests showed this beneficial fungus prevented rust infection in 91% of cases and completely stopped the disease from spreading when applied to infected coffee leaves. This natural biological control offers an environmentally friendly alternative to chemical pesticides for protecting coffee crops.

Coffee leaf rust is a major disease threatening coffee production worldwide. Researchers in China identified a naturally occurring fungus called Acremonium persicinum that parasitizes the rust fungus, effectively killing it. This biocontrol agent showed 91% inhibition of rust spore germination and completely prevented rust infection when applied together with the rust, offering a promising chemical-free solution for protecting coffee crops.
