Three New Records of Pathogens Causing Stem Blight on Vaccinium corymbosum in China

mycolabadmin

Researchers in China identified three new fungal species causing stem blight disease in blueberry crops. These fungi infect blueberry stems, causing brown lesions that kill the shoots and leaves. Laboratory tests confirmed all three fungi can cause the disease, with one species being particularly aggressive. This research helps farmers understand and manage this economically important disease that damages 10-25% of China’s blueberry crops.

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.

Complete genome sequence of Diaporthe vaccinii Shear, a fungal isolated from blueberry

mycolabadmin

Scientists have sequenced the complete genetic blueprint of a fungus called Diaporthe vaccinii that causes serious disease in blueberry plants. Using advanced DNA sequencing technology, they created a high-quality map of the fungus’s 60.2 million base pair genome. This genetic information will help researchers understand how the fungus causes disease and potentially develop better ways to protect blueberry crops from this costly plant pathogen.

Characterization of Fungal Pathogens Causing Blueberry Fruit Rot Disease in China

mycolabadmin

Researchers in China identified seven different fungi causing blueberry fruit rot disease from samples collected in Guizhou and Fujian provinces. Three of these fungi were found on blueberries for the first time. The study showed that blueberries can suffer from multiple fungal infections at once, both during growth and after harvest, causing significant crop losses. Understanding these different pathogens helps farmers develop better strategies to prevent and manage blueberry diseases.
