Green synthesis of silver nanoparticles by sweet cherry and its application against cherry spot disease

mycolabadmin

Researchers developed a natural, eco-friendly method to fight a fungal disease that damages sweet cherries after harvest. Using tiny silver particles created from cherry fruit extracts, they successfully stopped the growth of harmful Alternaria fungi. This approach offers farmers an environmentally safe alternative to traditional chemical fungicides while protecting cherry crops from rot.

Corrigendum: Active substances of myxobacteria against plant diseases and their action mechanisms

mycolabadmin

Myxobacteria are tiny soil organisms that can attack and destroy disease-causing fungi, bacteria, and water molds that harm plants. These bacteria produce natural enzymes and chemical compounds that break down pathogen cell walls and stop them from growing. This makes myxobacteria promising candidates for environmentally friendly pest control in farming.

Nanomaterials for Plant Disease Diagnosis and Treatment: A Review

mycolabadmin

Scientists are developing tiny particles called nanomaterials to fight plant diseases caused by bacteria, fungi, viruses, and worms. These nanoparticles can detect infections quickly and treat diseases more effectively than traditional pesticides, while reducing harmful environmental impacts. The technology shows promise for safer, more sustainable farming that could help feed a growing global population.

Biocontrol effects of Bacillus velezensis and Bacillus subtilis against strawberry root rot caused by Neopestalotiopsis clavispora

mycolabadmin

Researchers isolated three beneficial bacteria (two Bacillus velezensis strains and one Bacillus subtilis strain) that effectively fight strawberry root rot disease. These bacteria work by both directly killing the disease-causing fungus and boosting the strawberry plant’s natural immune system. The bacteria can live inside the strawberry plant and soil, providing long-lasting protection. This offers farmers an eco-friendly alternative to chemical fungicides for protecting their strawberry crops.

Nanoemulsion formulation of lemongrass essential oil using Pseudomonas-derived rhamnolipids for targeted phytopathogen suppression

mycolabadmin

This study developed a nano-sized formulation of lemongrass oil stabilized with naturally-derived rhamnolipid surfactant to fight plant fungal diseases. The formulation successfully inhibited the growth of three major plant pathogens and remained stable during storage. This bio-based approach offers farmers an environmentally-friendly alternative to synthetic chemical fungicides for protecting crops.

Emerging Role of Arbuscular Mycorrhizal Fungi in Sustainable Agriculture: From Biology to Field Application

mycolabadmin

Arbuscular mycorrhizal fungi are microscopic fungi that naturally partner with plant roots to help them grow stronger and healthier. These fungi can improve crop productivity without chemical fertilizers by helping plants absorb water and nutrients, resist drought and salty soils, and fight off diseases. Scientists are now developing commercial products containing these beneficial fungi to help farmers grow crops more sustainably and organically.

Molecular and Biological Characterization of an Isolate of Fusarium graminearum dsRNA mycovirus 4 (FgV4) from a New Host Fusarium pseudograminearum

mycolabadmin

Scientists discovered a virus that infects the fungus responsible for wheat crown rot disease. When this virus infects the fungus, it slows down the fungus’s growth and reduces its ability to cause disease in wheat plants. This finding suggests the virus could potentially be used as a natural biological control method to protect wheat crops from crown rot disease, offering an environmentally friendly alternative to chemical fungicides.

The Biological Product Agricultural Jiaosu Enhances Tomato Resistance to Botrytis cinerea

mycolabadmin

Agricultural Jiaosu is a fermented product made from plant waste that effectively controls gray mold disease in tomatoes through two mechanisms: it directly kills the fungus with organic acids, and it strengthens the plant’s natural defenses. When applied as a spray to tomato leaves once a week, it reduced disease by 55%, made plants grow taller and stronger, and boosted the plants’ protective enzymes. This natural alternative to chemical fungicides offers a sustainable and safe way to protect tomato crops while maintaining environmental health.

Dual benefits of Lysinibacillus xylanilyticus strain GIC41 in mitigating Pythium root rot and enhancing plant growth across cultivation systems

mycolabadmin

Scientists tested a bacteria strain called Lysinibacillus xylanilyticus (GIC41) to fight a destructive plant disease called Pythium root rot. In both soil and water-based growing systems, this bacteria significantly reduced disease symptoms in spinach and tomato plants while also making the plants grow bigger and stronger. The bacteria works by producing enzymes and possibly triggering the plant’s natural defenses, without directly poisoning the disease-causing pathogen.

SsMet1 is a critical gene in methionine biosynthesis in Sclerotinia sclerotiorum

mycolabadmin

Sclerotinia sclerotiorum is a destructive plant pathogen causing white mold and other crop diseases. This study identified and deleted the SsMet1 gene, which is essential for methionine production in this fungus. Fungi lacking this gene could not grow properly, form survival structures called sclerotia, or infect plants. These findings suggest that blocking methionine biosynthesis could be a new way to develop fungicides against this important crop pathogen.
