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

mycolabadmin

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.

The yeast Wickerhamomyces anomalus acts as a predator of the olive anthracnose-causing fungi, Colletotrichum nymphaeae, C. godetiae, and C. gloeosporioides

mycolabadmin

Researchers discovered that a yeast called Wickerhamomyces anomalus can effectively control olive anthracnose, a fungal disease that damages olive crops. The yeast acts like a predator, sticking to the fungal hyphae, wrapping them in a sticky substance, and draining their contents. This finding offers a greener alternative to chemical fungicides for protecting olive trees before harvest.

Abscisic Acid Metabolizing Rhodococcus sp. Counteracts Phytopathogenic Effects of Abscisic Acid Producing Botrytis sp. on Sunflower Seedlings

mycolabadmin

Researchers discovered that a beneficial soil bacterium (Rhodococcus sp.) can protect sunflower plants from a harmful fungus (Botrytis sp.) by breaking down a plant stress hormone (ABA) that the fungus produces to weaken plant defenses. Unlike other protection methods that kill the fungus or boost immune responses, this bacterium works by removing the fungus’s chemical weapon. This discovery suggests new ways to protect crops from diseases.

Biocontrol of Fusarium oxysporum f. sp. cepae on Indonesian Local Garlic Plants (Lumbu Hijau) Using a Consortium of Bacillus amyloliquefaciens B1 and Arbuscular Mycorrhizal Fungi

mycolabadmin

Researchers in Indonesia developed a natural way to protect garlic plants from a serious fungal disease using a combination of beneficial bacteria (Bacillus amyloliquefaciens) and fungi (arbuscular mycorrhizal fungi). When applied together, these microorganisms reduced disease by 84% while also making the garlic plants grow taller and produce more biomass. This provides farmers with an environmentally friendly alternative to chemical fungicides.
