In vitro and in vivo inhibitory effects and transcriptional reactions of graphene oxide on Verticillium dahliae

mycolabadmin

Graphene oxide, a nanomaterial derived from graphene, effectively inhibits the growth of Verticillium dahliae, a fungus that causes devastating wilt disease in cotton and many other plants. The study shows that graphene oxide damages the fungal cell membrane and disrupts key metabolic processes, preventing the fungus from growing and infecting plants. When applied to cotton plants, graphene oxide treatment significantly reduced wilt disease symptoms, suggesting it could be a promising alternative to chemical fungicides for controlling this important agricultural disease.

Botryosphaeriaceae Species Causing Stem Blight and Dieback of Blueberries in Serbia

mycolabadmin

Researchers in Serbia studied fungal diseases affecting blueberry plants and identified four different disease-causing fungi. They found that Lasiodiplodia iraniensis, a fungus previously unknown on blueberries worldwide, is now infecting Serbian blueberry orchards. The study shows that the ‘Duke’ blueberry variety is more susceptible to infection than other varieties, and that the disease likely spreads through infected planting materials used to establish new orchards.

Biological characterization and in vitro fungicide screening of a new pathogen of basal stem rot of Schisandra chinensis in Jilin Province, China

mycolabadmin

Researchers discovered that a fungus called Ilyonectria robusta is causing a serious disease in Schisandra chinensis plants grown in northern China. This plant is used to make traditional Chinese medicine. The disease causes the base of the plant stems to rot and die. Scientists tested seven different fungicides (medicines that kill fungi) and found that fluazinam was the most effective at stopping this fungus from growing.

Comparative Antagonistic Activities of Endolichenic Fungi Isolated from the Fruticose Lichens Ramalina and Usnea

Researchers studied fungi living inside lichen plants from the Philippines to see if they could help fight crop diseases. They tested 40 different fungi against three harmful pathogens that destroy important crops. The results showed that these lichen-dwelling fungi were effective at stopping pathogen growth, with fungi from Ramalina lichens performing better than those from Usnea lichens. This discovery suggests a natural, eco-friendly way to protect crops without harsh chemicals.

Identification and virulence factors prediction of Didymella segeticola causing leaf spot disease in Asarum heterotropoides in China

mycolabadmin

This research identifies a fungal disease causing serious damage to Chinese wild ginger crops in northeastern China. Scientists found that the fungus Didymella segeticola causes leaf spot disease and identified 87 proteins that help the fungus harm the plants. The study provides important information for developing strategies to prevent this disease and protect this valuable medicinal herb crop.

2-Nonanol produced by Bacillus velezensis EM-1: a new biocontrol agent against tobacco brown spot

mycolabadmin

Researchers discovered that a beneficial bacterium called Bacillus velezensis produces a natural compound called 2-nonanol that effectively kills the fungus causing brown spots on tobacco leaves. This compound works by disrupting the fungus’s ability to obtain energy and handle stress. Testing on tobacco leaves showed that 2-nonanol could significantly reduce disease development. This discovery offers a promising environmentally-friendly alternative to chemical fungicides for protecting tobacco crops.

Integrated use of biochar, Cassia fistula, and Trichoderma for sustainable management of Sclerotium rolfsii in chickpea

mycolabadmin

This study shows how combining three natural substances—rice husk biochar (a carbon-rich soil additive), Cassia fistula plant extract, and a beneficial fungus called Trichoderma harzianum—can effectively protect chickpea crops from a harmful soil disease called collar rot. The combination not only reduced disease occurrence from 64% to 35% but also improved plant growth and strengthened plants’ natural defense mechanisms. This eco-friendly approach offers farmers a sustainable alternative to chemical fungicides while improving soil health and crop productivity.

Identifying Key Pathogens and Effective Control Agents for Astragalus membranaceus var. mongholicus Root Rot

mycolabadmin

Astragalus root, a valued traditional Chinese medicine, suffers from a serious fungal disease caused primarily by two Fusarium species. Researchers tested eight fungicides and nine beneficial bacteria to find the most effective treatments. The chemical fungicide carbendazim and a beneficial bacterium called KRS006 proved most effective, offering promise for developing better disease management strategies that combine both chemical and biological approaches.

Polyherbal nanoformulation: a potent antifungal agent on fungal pathogens of Coffea arabica

mycolabadmin

Researchers developed an eco-friendly nano-formulation from Triphala to fight fungal diseases that harm coffee plants. The treatment effectively stopped the growth of five different harmful fungi that infect coffee leaves. This green nanotechnology approach offers farmers a safer, environmentally friendly alternative to chemical fungicides that can pollute the environment and harm human health.
