Automatic classification of fungal-fungal interactions using deep learning models

mycolabadmin

Researchers developed a computer artificial intelligence system that can automatically analyze images of fungal interactions to identify strains that could help control harmful crop diseases. Instead of having humans manually examine thousands of fungal culture plates—a slow and subjective process—the AI system can now classify the interactions between beneficial fungi and plant pathogens with 95% accuracy. This breakthrough significantly speeds up the search for natural alternatives to synthetic pesticides, supporting sustainable agriculture and food security.

Bacillus subtilis ED24 Controls Fusarium culmorum in Wheat Through Bioactive Metabolite Secretion and Modulation of Rhizosphere Microbiome

mycolabadmin

A beneficial bacteria called Bacillus subtilis ED24 was found to effectively protect wheat plants from a destructive fungal disease called Fusarium culmorum. When applied to wheat seeds, this bacteria improved seed germination and plant growth better than a commercial chemical fungicide, while also promoting helpful microorganisms in the soil around the plant roots. The bacteria works by producing special chemical compounds that kill the harmful fungus and by enriching the soil microbiome with beneficial organisms.

Volatile Metabolome and Transcriptomic Analysis of Kosakonia cowanii Ch1 During Competitive Interaction with Sclerotium rolfsii Reveals New Biocontrol Insights

mycolabadmin

Researchers found that a bacterium called K. cowanii produces special gases (volatile organic compounds) that kill fungal plant diseases like those caused by Sclerotium rolfsii. When grown together with this fungus, the bacterium produces these toxic gases which inhibit fungal growth by up to 80%. The study identified specific genes the bacteria activate to produce these antifungal compounds, offering a natural alternative to chemical fungicides for protecting crops.

Antifungal Volatile Organic Compounds from Talaromyces purpureogenus CEF642N: Insights from One Strain Many Compounds (OSMAC) Strategy for Controlling Verticillium dahliae in Cotton

mycolabadmin

Scientists discovered that a beneficial fungus called Talaromyces purpureogenus can produce powerful antifungal compounds that kill cotton wilt disease. By growing this fungus on different nutrient media, researchers identified two main antifungal compounds: 3-octanol and 2-octenal. These natural compounds completely or nearly completely stopped the growth of the cotton wilt pathogen in laboratory tests, offering a promising green alternative to chemical pesticides for protecting cotton crops.

Isolation and Biological Control of Colletotrichum sp. Causing Anthracnosis in Theobroma cacao L. in Chiapas, Mexico

mycolabadmin

Cacao farmers in Mexico’s Chiapas region face serious crop losses from anthracnose, a fungal disease caused by Colletotrichum. Researchers found a beneficial bacterium called Paenibacillus sp. NMA1017 that can suppress this disease as effectively as commercial fungicide alternatives. By testing this natural biocontrol agent both in the laboratory and on actual cacao farms, they demonstrated it could reduce disease occurrence from 65% down to just 12-20%, offering farmers a sustainable alternative to chemical treatments.

Beauveria felina Accelerates Growth When Competing With Other Potential Endophytes

mycolabadmin

Scientists studied how Beauveria felina, a fungus used to fight crop pests, grows when competing with other fungi naturally found in plants. Surprisingly, B. felina grew faster when other fungi were present, making it an even stronger candidate for pest control. However, the researchers found complex interactions between the fungi that need more study before using B. felina widely in agriculture.

Impact of Oxalic Acid Consumption and pH on the In Vitro Biological Control of Oxalogenic Phytopathogen Sclerotinia sclerotiorum

mycolabadmin

This research shows how bacteria can protect crops from a destructive fungus called Sclerotinia sclerotiorum. While scientists previously thought the bacteria worked by eating the toxic acid produced by the fungus, this study reveals that the bacteria also make the environment more alkaline (less acidic), which the fungus cannot tolerate. The combination of both effects—consuming the acid and changing the pH—is what actually stops the fungus from growing and damaging crops.

The Impact of Sugar Beet Seed Pelletization on the Proliferation of Nematophagous Fungi

mycolabadmin

Sugar beet seeds are often coated with protective chemicals to improve planting. This study found that these chemical coatings significantly inhibit the growth of beneficial fungi that naturally attack plant-damaging nematodes. While these fungi can still be applied to fields separately as a biological pest control, they should not be added directly to the seed coating because the chemicals would kill them. Farmers could use a combination approach by applying the fungi to soil separately while using treated seeds.

Biocontrol of Root-Knot Nematodes via siRNA-Loaded Extracellular Vesicles From a Nematophagous Fungus Arthrobotrys oligospora

mycolabadmin

Scientists developed a new way to control harmful root-knot nematodes that damage crops by using natural containers called extracellular vesicles from a fungus. These vesicles carry small RNA molecules that silence genes essential for nematode survival and reproduction. When tested on tomato plants, this fungal-based treatment reduced nematode damage by about 60% while promoting healthier plant growth, offering an eco-friendly alternative to chemical pesticides.

Green Synthesized Copper-Oxide Nanoparticles Exhibit Antifungal Activity Against Botrytis cinerea, the Causal Agent of the Gray Mold Disease

mycolabadmin

Scientists developed tiny copper oxide particles using fungi to create a natural fungicide that fights gray mold, a disease that damages grapes and other crops worldwide. These bio-based nanoparticles work better than conventional copper fungicides, offering farmers a more environmentally friendly option. However, the particles showed some toxicity to human cells in laboratory tests, suggesting they need careful handling before field use.
