Synthesis of silver nanoparticles employing Polyalthia longifolia leaf extract and their in vitro antifungal activity against phytopathogen

mycolabadmin

Scientists successfully created tiny silver particles using leaves from the Polyalthia longifolia plant, an evergreen tree native to India. These silver nanoparticles proved highly effective at stopping the growth of Alternaria alternata, a fungus that damages crops and causes leaf spot disease. The method is inexpensive, environmentally friendly, and the particles remain stable for months, making them a promising natural alternative to chemical fungicides for protecting plants.

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

mycolabadmin

Researchers identified a fungus called Didymella segeticola as the cause of a leaf spot disease affecting Chinese wild ginger, a valuable medicinal plant grown in northeastern China. The disease is causing significant crop losses, with up to 75% of fields affected. Scientists analyzed the fungus’s genes and identified 87 proteins that help it cause disease, which could help develop better ways to prevent the disease in the future.

Overview of the Genus Pseudocercospora on Vitaceous Plants in Korea with Introduction of Pseudocercospora neovitis sp. nov.

mycolabadmin

Researchers in Korea identified and characterized three fungal species that cause leaf spot diseases on grape plants and related vines. They discovered a new fungal species called Pseudocercospora neovitis on wild grapes (Vitis flexuosa) and found that a common grape leaf spot fungus (Ps. vitis) also infects the commercial grape variety Campbell Early in Korea. These findings help understand the diversity of fungal pathogens affecting grape production and related plants.
