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.

Chitosan-mediated copper nanohybrid attenuates the virulence of a necrotrophic fungal pathogen Macrophomina phaseolina

mycolabadmin

Researchers developed tiny copper particles coated with chitosan (a natural compound from shellfish) that effectively kill a destructive fungus called Macrophomina phaseolina, which damages hundreds of plant species worldwide. When used at the right concentration, these nanoparticles completely stopped the fungus from growing while causing minimal damage to plants. This innovation offers a promising natural alternative to traditional chemical fungicides for protecting crops while being more environmentally friendly and sustainable.

Effects of Thifluzamide Treatment on the Production of Cell Wall Degrading Enzymes in Rhizoctonia solani and Phenylpropane Metabolism in Pear Fruit

mycolabadmin

A new fungicide called thifluzamide was tested on pear fruits infected with a fungus that causes rot. The fungicide works in two ways: it stops the fungus from producing enzymes that break down plant cell walls, and it boosts the pear’s natural defense system by increasing protective compounds like flavonoids and phenolic acids. This dual action makes thifluzamide a promising treatment for preventing fruit rot during storage and transport.

Cystobacter fuscus HM-E: a novel biocontrol agent against cotton Verticillium wilt

mycolabadmin

A naturally occurring bacterium called Cystobacter fuscus shows great promise as a biological control agent against a serious fungal disease that damages cotton plants. When formulated as a solid product and applied to soil, this microorganism was able to prevent disease in over 70% of cotton plants tested in greenhouse experiments. The bacteria work by attacking and breaking down the fungal pathogen while also promoting healthier plant growth, offering farmers an environmentally friendly alternative to chemical fungicides.

Analysis of the Differences in Rhizosphere Microbial Communities and Pathogen Adaptability in Chili Root Rot Disease Between Continuous Cropping and Rotation Cropping Systems

mycolabadmin

Rotating crops (chili with cotton) instead of continuously planting chili improves soil health by increasing helpful bacteria like Bacillus and reducing harmful fungi like Fusarium that cause root rot disease. Researchers studied how different cropping systems change the mix of microorganisms in soil around plant roots and identified two main disease-causing fungi. This research shows that crop rotation is a natural, chemical-free way to prevent chili disease and maintain productive farmland.

In vitro biocontrol potential of plant extract-based formulation against infection structures of Phytophthora infestans along with lower non-target effects

mycolabadmin

Researchers tested a plant extract-based treatment against late blight, a serious disease affecting potatoes and tomatoes caused by Phytophthora infestans. The formulated product was highly effective at very low concentrations, stopping the disease at multiple stages of infection. Importantly, it had minimal harmful effects on beneficial microorganisms, making it a promising eco-friendly alternative to synthetic fungicides.

A bibliometric analysis of fungal volatile organic compounds

mycolabadmin

Fungi release distinctive smells made up of volatile compounds that help them communicate with plants, bacteria, and other organisms. These fungal smell chemicals have grown from being studied mainly in wine fermentation to being explored for helping crops grow better, fighting plant diseases naturally, and creating food flavors without chemicals. This research shows that understanding how fungi use these smell chemicals could lead to more sustainable farming practices and natural alternatives to harmful pesticides.

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.

Functional analysis of a novel endo-β-1,6-glucanase MoGlu16 and its application in detecting cell wall β-1,6-glucan of Magnaporthe oryzae

mycolabadmin

Scientists discovered and studied a special enzyme called MoGlu16 from rice blast fungus that breaks down a key component of fungal cell walls called β-1,6-glucan. This enzyme can be used to visualize where this cell wall component is located in the fungus at different stages of its life cycle. When applied to fungus spores, the enzyme prevents them from sprouting and forming infection structures, making it a promising candidate for developing new ways to control rice blast disease.

Analysis of the Differences in Rhizosphere Microbial Communities and Pathogen Adaptability in Chili Root Rot Disease Between Continuous Cropping and Rotation Cropping Systems

mycolabadmin

This study shows that rotating chili crops with cotton significantly improves soil health and reduces chili root rot disease compared to continuous chili cultivation. By changing crops, beneficial bacteria like Bacillus increase while disease-causing fungi like Fusarium decrease in the soil. The research identifies the main pathogens causing chili root rot and their growth preferences, providing farmers with a scientific basis for using crop rotation as a natural, sustainable alternative to chemical pesticides.
