Bacillus velezensis CNPMS-22 as biocontrol agent of pathogenic fungi and plant growth promoter

mycolabadmin

A bacterial strain called Bacillus velezensis CNPMS-22 shows promise as a natural pest control agent for crops. When applied to maize seeds, it reduced fungal diseases and increased plant productivity as effectively as chemical fungicides. The bacteria produces natural compounds that kill harmful fungi while also promoting plant growth, offering a safer, more environmentally friendly alternative to synthetic chemicals.

Integrated use of biochar, Cassia fistula, and Trichoderma for sustainable management of Sclerotium rolfsii in chickpea

mycolabadmin

Researchers tested a natural approach to protect chickpea crops from a harmful soil fungus called Sclerotium rolfsii. They combined three natural substances: charred rice husks (biochar), an extract from the Cassia fistula plant, and a beneficial fungus called Trichoderma harzianum. The results showed this combination significantly reduced disease by 45% while also making plants grow stronger and healthier, offering farmers an eco-friendly alternative to chemical fungicides.

Biocontrol Potential of Bacillus velezensis RS65 Against Phytophthora infestans: A Sustainable Strategy for Managing Tomato Late Blight

mycolabadmin

Researchers tested 30 soil bacteria from tomato roots to find natural disease fighters. They discovered that Bacillus velezensis RS65, a beneficial bacterium, effectively prevents tomato late blight by producing enzymes and toxins that kill the fungal pathogen. In greenhouse tests, plants treated with RS65 had half the disease severity compared to untreated plants, suggesting this bacteria could replace chemical fungicides in sustainable tomato farming.

The Structural and Functional Diversities of Bacteria Inhabiting Plant Woody Tissues and Their Interactions with Fungi

Bacteria living in tree wood work together with fungi to break down wood and nutrients, which is important for forest health. Some bacteria can protect trees from harmful fungi by fighting them off, making them useful for controlling plant diseases. Understanding how bacteria and fungi interact in wood can help us grow healthier plants, manage tree diseases better, and improve wood decomposition processes.

Biocontrol efficiency and mechanism of novel Streptomyces luomodiensis SCA4-21 against banana Fusarium wilt

mycolabadmin

A newly discovered bacterium called Streptomyces luomodiensis SCA4-21 offers a natural solution to banana Fusarium wilt, a serious disease that destroys banana crops globally. When applied to banana plants, this beneficial bacterium reduced disease occurrence by 59% while also promoting healthier plant growth. The bacterium works by producing antifungal compounds that kill the disease-causing fungus and by enriching the soil with other helpful microorganisms that protect the plant.

Mechanism Analysis of Amphotericin B Controlling Postharvest Gray Mold in Table Grapes

mycolabadmin

This research shows that amphotericin B, a natural compound produced by bacteria, can effectively prevent gray mold from spoiling table grapes after harvest. The compound works by damaging the mold’s cell membranes and also activates the grapes’ own defense systems. At a treatment level of 200 mg/L, it completely prevented mold growth on grapes over a three-day storage period, offering a safer, more environmentally friendly alternative to synthetic fungicides.

Mycobiome of low maintenance iconic landscape plant boxwood under repeated treatments of contact and systemic fungicides

mycolabadmin

This study examined how different fungicide treatments affect the beneficial and harmful fungi living on boxwood plants. Researchers found that repeated applications of chlorothalonil-based fungicides reduced many beneficial fungi while having minimal effect on harmful pathogens, and that fungi became less sensitive to the same fungicide over time. The findings suggest that choosing the right fungicide and application method is important for maintaining plant health and preventing fungicide resistance.

Identification of Trichoderma spp., Their Biomanagement Against Fusarium proliferatum, and Growth Promotion of Zea mays

mycolabadmin

Researchers isolated and tested special fungi called Trichoderma that can fight crop disease-causing fungi and promote plant growth. When applied to maize plants infected with disease-causing Fusarium, the Trichoderma fungi completely eliminated the disease and made the plants grow healthier and larger. This natural approach offers farmers a chemical-free alternative to protect crops while improving plant health.

Integrated use of biochar, Cassia fistula, and Trichoderma for sustainable management of Sclerotium rolfsii in chickpea

mycolabadmin

This study shows how combining three natural substances—rice husk biochar (a carbon-rich soil additive), Cassia fistula plant extract, and a beneficial fungus called Trichoderma harzianum—can effectively protect chickpea crops from a harmful soil disease called collar rot. The combination not only reduced disease occurrence from 64% to 35% but also improved plant growth and strengthened plants’ natural defense mechanisms. This eco-friendly approach offers farmers a sustainable alternative to chemical fungicides while improving soil health and crop productivity.

Biocontrol Potential of a Mango-Derived Weissella paramesenteroides and Its Application in Managing Strawberry Postharvest Disease

mycolabadmin

Researchers discovered a beneficial bacterium called Weissella paramesenteroides that naturally lives on mango fruit and can protect strawberries from fungal diseases during storage. The bacterium works by releasing special chemicals in the air called volatile organic compounds that prevent mold growth without direct contact. This provides a natural, food-safe alternative to synthetic fungicides for keeping fresh fruit fresher longer.
