Streptomyces-Based Bioformulation to Control Wilt of Morchella sextelata Caused by Pestalotiopsis trachicarpicola

mycolabadmin

Morels are valuable mushrooms threatened by fungal wilt disease in China. Researchers isolated two beneficial bacteria (Streptomyces) from morel soil that naturally fight the fungal disease. When applied to morel fields, these bacteria reduced disease and increased mushroom yield by 30% compared to untreated fields. This represents a natural, eco-friendly solution to protect morel crops and boost production without chemical fungicides.

Pathogen identification and biological fungicides screening for Plumbago auriculata blight in China

mycolabadmin

Researchers in China identified a fungal disease affecting Plumbago auriculata (cape leadwort), a popular ornamental plant. The disease was caused by Fusarium ipomoeae, a fungus that causes yellowing and death of plant tissue. Scientists tested seven biological pesticides and found that osthole, a natural compound, was most effective at controlling the fungus and preventing disease.

Detection of Pestalotiopsis abbreviata sp. nov., the Causal Agent of Pestalotiopsis Leaf Blight on Camellia japonica Based on Metagenomic Analysis

mycolabadmin

Researchers discovered a new fungal species called Pestalotiopsis abbreviata that causes leaf disease on Camellia japonica, an ornamental tree popular in Korea. Instead of using traditional time-consuming laboratory methods, they used advanced genetic sequencing (metagenomic analysis) to quickly identify the fungus among hundreds of other microbes living on the tree leaves. This new approach is faster and more accurate than old methods, making it easier to monitor and manage plant diseases in the future.

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 identified on buckwheat in China. Scientists studied how the fungus grows and found it prefers temperatures around 25°C and neutral pH levels. The fungus can also infect other important crops like wheat, corn, potatoes, and oats, which could pose a significant threat to agriculture in the region.

The Novel Disease Vicia unijuga Caused by Colletotrichum tofieldiae in China: Implications for Host Growth, Photosynthesis, and Nutritional Quality

mycolabadmin

Scientists in China discovered that a fungus called Colletotrichum tofieldiae causes a disease called anthracnose in perennial vetch (Vicia unijuga), an important forage crop used for animal feed. When plants get infected with this fungus, they become weak, their ability to photosynthesize decreases, and the nutritional quality of the plant drops significantly, reducing its value as animal feed. The fungus can also infect other legume crops like alfalfa and clover, showing it has a broad range of potential host plants.

Exploring fungal pathogens to control the plant invasive Rubus niveus on Galapagos Island San Cristobal

mycolabadmin

Hill raspberry is a highly invasive plant that has taken over approximately 30,000 hectares of the Galapagos Islands, threatening native plant species. Traditional control methods like manual removal and herbicide spraying are expensive and ineffective. Researchers identified five species of fungal pathogens that naturally occur on infected Hill raspberry plants and can cause disease on healthy plants, offering promise as biological control agents to suppress this invasive species.

Schizophyllum radiatum: An uncommon culprit of invasive fungal rhinosinusitis in an immunocompetent patient – A case report from India

mycolabadmin

A 32-year-old healthy woman in India developed a serious fungal infection in her sinuses caused by an unusually rare fungus called Schizophyllum radiatum. Doctors removed the infected material through surgery and identified the fungus using genetic sequencing when standard methods failed. Treatment with antifungal medication successfully cleared the infection, and the patient fully recovered.

Mediastinal cryptococcoma as part of disseminated cryptococcosis in HIV-negative pregnant woman with Myasthenia Gravis: Autopsy case report

mycolabadmin

A 29-year-old pregnant woman with myasthenia gravis died from a widespread fungal infection caused by Cryptococcus, which formed a large mass in her chest. Although she tested negative for HIV, her use of immunosuppressive medications to treat her muscle disease, combined with pregnancy’s natural effects on immune function, made her vulnerable to this serious fungal infection. The infection was initially misdiagnosed as tuberculosis, and the diagnosis was only confirmed after her death during autopsy, highlighting the importance of testing for fungal infections even in patients without HIV.

Inhibitory Effects of Origanum vulgare Essential Oil on Mycogone perniciosa Growth in Agaricus bisporus Cultivation

mycolabadmin

A new study shows that oregano essential oil can effectively prevent and treat wet bubble disease in button mushrooms, a fungal infection that costs farmers millions in crop losses. The oil works better than conventional chemical fungicides and contains powerful antifungal compounds like carvacrol and thymol. When applied at the right time, oregano oil completely stopped the disease from developing while maintaining healthy mushroom yields. This natural solution could help organic mushroom farmers reduce their reliance on synthetic chemicals.

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.
