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

mycolabadmin

Researchers discovered a serious fungal disease affecting buckwheat crops in China caused by Colletotrichum kahawae, a fungus that ranks among the world’s most damaging plant pathogens. Through laboratory tests, they identified the fungus and determined its optimal growth conditions and which other crops it can infect, including wheat, oats, potatoes, and maize. This is the first time this particular fungus has been reported on buckwheat, and the findings will help farmers develop strategies to prevent and manage the disease.

Aspergillus latus: A cryptic causative agent of aspergillosis emerging in Japan

mycolabadmin

Researchers in Japan discovered that a dangerous fungus called Aspergillus latus, previously unknown in the country, has been causing infections since at least 2013. This fungus is difficult to identify because it looks similar to other related species and is actually a hybrid created from two different Aspergillus species. The study found seven cases of this fungus in clinical samples and discovered that it is resistant to some common antifungal medications, making accurate identification crucial for proper patient treatment.

Postharvest Disease Management of ‘Akizuki’ Pear in China: Identification of Fungal Pathogens and Control Efficacy of Chlorine Dioxide

‘Akizuki’ pears are a popular fruit in China but often develop rot diseases during storage, causing significant economic losses. Researchers identified four types of fungi responsible for this rot and tested chlorine dioxide gas as a treatment. The study found that chlorine dioxide effectively kills these fungi by damaging their cell membranes and works as well as commercial fungicides, offering a safer alternative for preserving pears without harmful chemical residues.

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

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.

Isolation, Identification, and In Vitro Fungicide Screening of the Pathogen Associated with Pear Dry Blight

mycolabadmin

Pear dry blight is a serious fungal disease affecting pear orchards in China. Researchers identified the fungus Diaporthe fukushii as the cause and tested various fungicides to find the most effective treatments. The study found that thiophanate-methyl and difenoconazole mixed with propiconazole work best, while some other fungicides are less effective. The research provides farmers with evidence-based strategies to manage this devastating disease.

Postharvest Disease Management of ‘Akizuki’ Pear in China: Identification of Fungal Pathogens and Control Efficacy of Chlorine Dioxide

mycolabadmin

Researchers identified four types of fungi that cause rot in ‘Akizuki’ pears during storage: Alternaria alternata, Diaporthe eres, and two types of Penicillium. They tested chlorine dioxide gas as a treatment and found it effectively stopped the fungi from growing without harming the fruit. This discovery offers a safer, more environmentally friendly alternative to traditional fungicide chemicals for keeping stored pears fresh longer.

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

mycolabadmin

Researchers identified a fungal pathogen (Fusarium ipomoeae) causing a serious disease in Plumbago auriculata ornamental plants in China. They tested seven biological fungicides and found that osthole was the most effective at preventing the disease. The study provides gardeners and farmers with an environmentally friendly solution to control this plant disease using a natural compound.

Ventilator-associated pneumonia caused by a new-found opportunistic fungal pathogen—Myceliophthora heterothallica: a case report

mycolabadmin

A 67-year-old woman suffered cardiac arrest and required a breathing machine to survive. While on the ventilator, doctors discovered an unusual fungal infection in her lungs caused by Myceliophthora heterothallica, which had never been documented as a human pathogen before. With standard bacterial antibiotics and supportive care, the patient recovered and was discharged after four weeks, suggesting this fungus may be less dangerous than related species.

Diversity of Fungal Genera Associated with Shot-Hole Disease in Cherry Blossoms Across Korea

mycolabadmin

Cherry blossom trees in Korea are commonly affected by shot-hole disease, which causes holes in leaves and reduces flowering. Researchers found that four different fungi cause this disease, not just one as previously thought: Alternaria, Diaporthe, Epicoccum, and Botryosphaeria. The types of fungi vary by region and between urban and rural areas, suggesting different management strategies may be needed in different locations.

Biological and Genomic Insights into Fusarium acuminatum Causing Needle Blight in Pinus tabuliformis

mycolabadmin

Researchers identified a fungus called Fusarium acuminatum as the cause of needle blight disease affecting Chinese pine trees in northern China. They studied how this fungus grows and sequenced its entire genome to understand how it damages the trees. The findings help explain the disease and provide tools to develop better ways to protect and treat infected pine trees.
