Exo-metabolome profiling of soybean endophytes: a road map of antagonism against Fusarium oxysporum

mycolabadmin

Scientists discovered that certain beneficial bacteria living inside soybean roots can protect the plant from a harmful fungus that causes root rot and reduces crop yield. By analyzing the chemical compounds these bacteria produce, researchers identified specific antifungal substances that kill or inhibit the pathogenic fungus. These findings suggest that instead of using harmful chemical fungicides, farmers could use these beneficial bacteria as a natural, environmentally-friendly way to protect soybean crops and improve agricultural sustainability.

The dark side of avocados: a review of anthracnose and stem-end rot in postharvest fruit

mycolabadmin

Avocados are a valuable global fruit crop, but two fungal diseases—anthracnose and stem-end rot—cause major economic losses by making fruit unmarketable. These fungi infect avocados in the orchard but remain hidden until the fruit ripens, making them difficult to detect and control. Recent advances in detection technology and disease management strategies, including biological controls and natural treatments, offer promising solutions to reduce losses and keep avocados fresh from farm to table.

Transmission of apple stem grooving virus (Capillovirus mali) to apple from the soil-borne fungus Fusarium solani

mycolabadmin

Researchers discovered that a common soil fungus called Fusarium solani can carry and transmit apple viruses to healthy apple trees through their roots. This fungus spreads the virus both to other fungal colonies and to apple plants, explaining how viruses naturally spread in apple orchards. This finding has important implications for protecting apple orchards and managing orchard soil health.

High temperature enhances the ability of Trichoderma asperellum to infect Pleurotus ostreatus mycelia

mycolabadmin

Researchers discovered that summer heat makes oyster mushroom crops more vulnerable to green mold disease caused by a fungus called Trichoderma asperellum. When exposed to high temperatures (36°C), the pathogenic fungus becomes more aggressive by producing more spores, germinating faster, and generating molecules like hydrogen peroxide that damage the mushroom mycelia. Meanwhile, the oyster mushroom itself becomes more susceptible to infection at these higher temperatures, explaining why green mold outbreaks are so common during hot summer months in mushroom farms.

Identification of Pseudocercospora mori as the causal agent of grey leaf spot disease in mulberry (Morus atropurpurea) from various localities in Guangdong Province, China

mycolabadmin

This study identifies the fungus Pseudocercospora mori as the cause of a serious disease affecting mulberry leaves in southern China. Researchers used microscopy, genetic testing, and laboratory experiments to confirm that this pathogen damages mulberry plants and reduces the quality of leaves used in silk production. The study provides practical diagnostic tools to help farmers detect and manage this disease in their mulberry orchards.

Twenty-nine new host records of powdery mildew fungi (Erysiphaceae) in Taiwan with an updated checklist

mycolabadmin

Scientists in Taiwan have updated a comprehensive list of powdery mildew fungi that infect plants, adding 29 new host plant records. They identified 13 different species of these fungi using both traditional microscopy and modern DNA sequencing techniques. This updated list is important for farmers and gardeners to identify and manage powdery mildew diseases on their crops and plants.

The Biocontrol and Growth-Promoting Potential of Penicillium spp. and Trichoderma spp. in Sustainable Agriculture

mycolabadmin

This review examines how two types of beneficial fungi, Penicillium and Trichoderma, can improve crop growth and protect plants from diseases without using chemical pesticides. These fungi work by colonizing plant roots, producing natural compounds that boost plant health, and fighting harmful pathogens. They are affordable, safe, and environmentally friendly alternatives for sustainable farming that can increase yields while reducing the need for synthetic fertilizers and fungicides.

Antifungal mechanism of nanosilver biosynthesized with Trichoderma longibrachiatum and its potential to control muskmelon Fusarium wilt

mycolabadmin

Researchers created tiny silver particles using a beneficial fungus to fight a serious disease that damages muskmelon plants. At low doses, these silver nanoparticles killed the disease-causing fungus while actually helping the melon plants grow better and germinate faster. The silver particles work by damaging the fungus’s cell structure and triggering harmful reactive oxygen species inside fungal cells, ultimately destroying them.

First Report of Colletotrichum kahawae Causing Anthracnose on Buckwheat (Fagopyrum tataricum) in China and Biological Characterization of the Pathogen

mycolabadmin

Researchers in China discovered that a fungus called Colletotrichum kahawae is causing a serious disease called anthracnose on buckwheat crops in Yunnan Province. This is the first time this particular fungus has been found on buckwheat, though it’s already known for causing disease on coffee plants worldwide. The scientists characterized how this fungus grows best under certain conditions and tested whether it could infect other important crops like corn, wheat, and potatoes, finding it could potentially harm these crops too.

Biology and Application of Chaetomium globosum as a Biocontrol Agent: Current Status and Future Prospects

mycolabadmin

Chaetomium globosum is a fungus that can protect crops from various plant diseases by producing toxic compounds and parasitizing harmful pathogens. It also helps plants defend themselves naturally and improves soil health by promoting beneficial microorganisms. This makes it a promising alternative to chemical pesticides for sustainable farming, though more research is needed to optimize its effectiveness in real field conditions.
