Native Bacteria Are Effective Biocontrol Agents at a Wide Range of Temperatures of Neofusicoccum parvum, Associated with Botryosphaeria Dieback on Grapevine

mycolabadmin

Researchers from Chile identified native bacteria (specifically Pseudomonas strains) that effectively prevent a destructive fungal disease affecting grapevines. These bacteria can work across a wide range of temperatures and significantly reduce fungal growth both in laboratory tests and in actual vineyard conditions. This discovery offers an environmentally friendly alternative to chemical fungicides for protecting grapevines, particularly important as younger vines appear more vulnerable to infection.

Morphological and Molecular Characterization of Lasiodiplodia theobromae Causing Stem Gummosis Disease in Rubber Trees and Its Chemical Control Strategies

mycolabadmin

Rubber trees in China experienced a serious stem gummosis disease that caused bark cracking and latex leakage in 2023. Scientists identified the fungus Lasiodiplodia theobromae as the cause through laboratory and molecular tests. They successfully treated the disease using a combination of copper-based fungicides applied to tree trunks and roots, preventing further damage to the trees.

Draft genome sequence of Neofusicoccum caryigenum associated with pecan leaf dieback

mycolabadmin

Scientists have sequenced the genetic blueprint of a fungus causing pecan leaf dieback disease, an emerging problem in southeastern U.S. pecan orchards. The fungus, called Neofusicoccum caryigenum, causes pecan trees to lose their leaves and produce fewer nuts. This first-ever genetic map of the pathogen will help researchers understand how it works and develop better ways to manage the disease.

Draft genome sequences for four isolates of the hemp (Cannabis sativa) fungal pathogen Neofusicoccum parvum

mycolabadmin

Scientists sequenced the complete genomes of four samples of a fungal disease that infects hemp plants. This fungus, called Neofusicoccum parvum, causes dying branches and damage to hemp crops. By mapping out the genetic code of these fungal samples, researchers now have important tools to better understand how this pathogen works and potentially develop strategies to protect hemp plants.

Whole-genome sequencing of global forest pathogen Diplodia sapinea causing pine shoot blight

mycolabadmin

This study presents a detailed genetic map of Diplodia sapinea, a fungus that causes serious disease in pine trees worldwide. Researchers sequenced the complete genome of a strain from China and compared it with related fungi to better understand how the pathogen causes disease. The high-quality genetic information provides important tools for scientists to develop better ways to prevent and control pine shoot blight, protecting valuable forests and timber resources.

Vulnerability of Walnut Pruning Wounds to Fungal Trunk Pathogens and Seasonal Conidial Dynamics of Botryosphaeriaceae in the Maule Region, Chile

mycolabadmin

When walnut trees are pruned, the resulting wounds are exposed to dangerous fungi that can cause branch die-back and significantly reduce crop yield. This research found that freshly cut pruning wounds are most vulnerable to infection, especially from aggressive fungi like Diplodia mutila, but this vulnerability decreases over time. The fungi spread their spores mainly during wet winter months when rainfall and humidity are high, so timing pruning operations to avoid these periods and protecting wounds with fungicides could substantially reduce disease losses in walnut orchards.

Whole-genome sequencing of global forest pathogen Diplodia sapinea causing pine shoot blight

mycolabadmin

Scientists have sequenced the complete genome of Diplodia sapinea, a fungus that causes serious disease in pine trees worldwide. This fungus normally lives harmlessly inside healthy pine trees but becomes dangerous during stressful conditions like droughts or storms. The new genome information will help scientists understand how this pathogen works and develop better ways to prevent and control the disease in forests.

Development of a molecular genetics and cell biology toolbox for the filamentous fungus Diplodia sapinea

mycolabadmin

Scientists have developed new tools to study a fungus called Diplodia sapinea that damages pine trees around the world. They created a method to genetically modify this fungus and tag its cell nuclei with a red fluorescent marker so they can track the infection process. They also developed a simple way to test infections using young pine seedlings in the laboratory instead of large greenhouse setups. Using these new tools together, researchers can now watch in real-time how the fungus grows inside infected pine plants, which will help develop better ways to protect forests.

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.

Assessment of Chemical and Biological Fungicides for the Control of Diplodia mutila Causing Wood Necrosis in Hazelnut

mycolabadmin

This study tested different fungicides to control a fungus that causes wood damage and necrosis in hazelnut trees in Chile. Researchers evaluated 30 different products in laboratory tests, pot experiments, and field trials over two growing seasons. The results showed that certain chemical fungicides and beneficial bacteria can effectively reduce damage from this disease, with effectiveness varying based on temperature conditions. These findings provide farmers with practical options for protecting hazelnut orchards from this damaging fungal disease.
