Anti-Therapeutic Action: phytotoxicity

A Comprehensive Review of the Diversity of Fungal Secondary Metabolites and Their Emerging Applications in Healthcare and Environment

mycolabadmin

Fungi naturally produce complex chemical compounds called secondary metabolites that have powerful effects against diseases and pests. These include well-known medicines like penicillin and compounds that can fight cancer, reduce inflammation, and lower cholesterol. Scientists are now using advanced genetic and biotechnology techniques to increase production of these fungal compounds, making them more available and affordable for medical, agricultural, and environmental applications. This research shows how fungi could be important sources of new medicines and sustainable alternatives to synthetic chemicals.

Production of the light-activated elsinochrome phytotoxin in the soybean pathogen Coniothyrium glycines hints at virulence factor

mycolabadmin

Researchers discovered that a fungus infecting soybean plants produces red toxins that become dangerous when exposed to light. These toxins generate reactive oxygen species that damage plant cells, causing leaf spots and disease. The study found that disease is worse under light conditions but can still occur in darkness, suggesting multiple attack mechanisms. Understanding this toxin production may help develop better disease management strategies for soybean crops, particularly in Africa where the disease is common.

In vitro antifungal activity of plant extracts against fungal pathogens of onion (Allium cepa L.) and red pepper (Capsicum annum L.) in selected districts of Western Hararghe, Ethiopia

mycolabadmin

Onion and pepper farmers in Ethiopia lose significant crops to fungal diseases, and chemical fungicides are expensive and harmful. This study tested plant extracts from garlic, neem, and African wintersweet against disease-causing fungi. Acokanthera schimperi (African wintersweet) was most effective at stopping fungal growth, offering farmers an affordable, natural, and environmentally safe alternative to chemical fungicides.

Impact of Various Essential Oils on the Development of Pathogens of the Fusarium Genus and on Health and Germination Parameters of Winter Wheat and Maize

mycolabadmin

Researchers tested four plant-based essential oils as natural alternatives to chemical fungicides for protecting wheat and maize seeds from harmful Fusarium fungi. Thyme oil proved most effective at preventing fungal infections and seedling disease, performing as well as synthetic fungicides. However, thyme oil at higher doses harmed seed germination and plant growth, suggesting careful dose selection is needed for practical use. The findings indicate essential oils could replace chemical pesticides while maintaining crop safety, though different oils must be tested for various crops.
