Roles of arbuscular mycorrhizal fungi in plant growth and disease management for sustainable agriculture

mycolabadmin

Arbuscular mycorrhizal fungi are beneficial fungi that live in plant roots and form a mutually beneficial relationship with plants. These fungi help plants absorb more nutrients and water from the soil, strengthen their natural defenses against diseases and pests, and work together with other helpful soil bacteria to create disease-suppressive soil. This makes AMF a promising natural alternative to chemical pesticides and fertilizers for sustainable agriculture.

Pest categorisation of Pestalotiopsis microspora

mycolabadmin

Pestalotiopsis microspora is a fungus that causes diseases on many cultivated and wild plants including avocado, banana, and kiwi fruit. It has been found in tropical and subtropical regions worldwide and was recently detected in the Netherlands. The fungus can enter the EU through infected plants, fruits, and contaminated soil from other countries. European scientists have determined it meets criteria to be classified as a quarantine pest requiring special phytosanitary measures to prevent its introduction.

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

mycolabadmin

A newly identified fungal disease caused by Fusarium ipomoeae is harming Plumbago auriculata plants in China. Scientists identified the pathogen using genetic analysis and tested seven plant-based treatments. They found that osthole, a natural compound, effectively controls the disease with 88% success rate, offering an environmentally friendly solution for protecting ornamental plants.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four types of fungi living inside plants without causing harm, called endophytic fungi. These fungi belong to a genus called Diaporthe and were identified using DNA analysis and microscopic examination. The study helps us understand the hidden diversity of fungi living in Korean plants and could lead to discovering new medicines or ways to control plant diseases.

Morphological and Molecular Characterization of Lasiodiplodia theobromae Causing Stem Gummosis Disease in Rubber Trees and Its Chemical Control Strategies

mycolabadmin

Rubber trees in China experienced a serious stem gummosis disease that caused bark cracking and latex leakage in 2023. Scientists identified the fungus Lasiodiplodia theobromae as the cause through laboratory and molecular tests. They successfully treated the disease using a combination of copper-based fungicides applied to tree trunks and roots, preventing further damage to the trees.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four previously unknown species of Diaporthe fungi living inside plant tissues without causing visible damage. These fungi were identified using genetic analysis and compared to known species from around the world. The findings show that Korea has more fungal diversity than previously documented and suggest these fungi could potentially be used to develop new medicines or help control plant diseases.

Exploring Fungal Communication Mechanisms in the Rhizosphere Microbiome for a Sustainable Green Agriculture

mycolabadmin

Fungi in soil communicate with each other and plants through chemical signals, forming protective layers called biofilms that help them cooperate and survive. These fungal communication networks can be either beneficial, helping plants grow and fight diseases, or harmful, causing crop infections and producing toxins. By better understanding how fungi talk to each other, scientists can develop natural ways to improve agriculture and clean up polluted soils without using harmful chemicals.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four new species of endophytic fungi called Diaporthe living inside plant tissues without causing visible disease. Using genetic testing and microscopic examination, they identified D. caryae, D. phoenicicola, D. stewartii, and D. unshiuensis as previously unrecorded in Korea. These fungi can potentially produce compounds with medicinal properties or help manage plant diseases. This discovery helps scientists better understand the hidden fungal diversity in Korean ecosystems.

Application of Nanocomposites-Based Polymers on Managing Fungal Diseases in Crop Production

mycolabadmin

Scientists are developing tiny particles made from natural materials like chitosan to protect crops from fungal diseases. These nanoparticles work better than traditional fungicides and can be combined with metals or plant extracts to boost their effectiveness. The new approach is more environmentally friendly and can reduce crop loss caused by fungal infections while maintaining sustainable agricultural practices.

Comprehensive analysis of the mechanisms conferring resistance to phenamacril in the Fusarium species

mycolabadmin

Fusarium fungi cause serious diseases in crops like wheat, rice, and vegetables worldwide, leading to significant food losses and contamination with harmful toxins. Phenamacril is a modern fungicide designed to fight these fungi by targeting a specific protein called myosin-5. However, the fungi have developed resistance to this fungicide through genetic changes and other mechanisms, making it less effective over time. Farmers need to use multiple strategies including crop rotation and resistant plant varieties rather than relying only on fungicides to successfully manage these diseases.
