Antifungal Effect of Cinnamon Bark Extract on the Phytopathogenic Fungus Fusarium sporotrichioides

mycolabadmin

This study tested whether cinnamon bark extract could stop the growth of a harmful fungus called Fusarium sporotrichioides that damages crops and produces toxins. Researchers used a water-based cinnamon extract at different concentrations on fungal cultures and found that the highest concentration significantly reduced fungal growth and caused visible damage to fungal structures. The cinnamon extract contains natural compounds with antifungal properties that could potentially be used as an eco-friendly alternative to synthetic fungicides in agriculture.

Development of Biphasic Culture System for an Entomopathogenic Fungus Beauveria bassiana PfBb Strain and Its Virulence on a Defoliating Moth Phauda flammans (Walker)

mycolabadmin

Researchers developed an efficient two-stage fermentation process to mass-produce Beauveria bassiana PfBb, a fungus that kills defoliating moths damaging Ficus trees. The first stage grows the fungus in liquid to produce active spores, which are then transferred to solid substrates to produce hardy, long-lasting conidia. The optimized process produces high quantities of effective fungal spores that can be stored at refrigerator temperature for over a year while maintaining their pest-killing ability.

Identification and Biological Characteristics of Alternaria gossypina as a Promising Biocontrol Agent for the Control of Mikania micrantha

mycolabadmin

Scientists discovered that a fungus called Alternaria gossypina can effectively kill an invasive weed called Mikania micrantha that threatens ecosystems worldwide. Through laboratory testing, they identified optimal conditions for growing this fungus and confirmed it can infect and damage the weed’s leaves. This discovery offers a promising natural and environmentally-friendly alternative to chemical herbicides for controlling this problematic invasive plant species.

Development of a granular bioformulation of Achromobacter xylosoxidans AX77 16S for sustainable onion white rot management and growth enhancement

mycolabadmin

Scientists discovered a beneficial bacterium living inside onion seeds that can fight a serious fungal disease called white rot and help seeds grow better. They turned this bacterium into an easy-to-use granular product that lasts up to a year, offering farmers an environmentally friendly alternative to chemical fungicides. The product not only prevents the fungal disease but also improves seed germination and plant growth, making it a promising sustainable solution for onion farming.

Impact of Oxalic Acid Consumption and pH on the In Vitro Biological Control of Oxalogenic Phytopathogen Sclerotinia sclerotiorum

mycolabadmin

Scientists studied how bacteria that eat oxalic acid can control a destructive plant fungus called Sclerotinia sclerotiorum. The fungus produces oxalic acid to damage crops, but when special bacteria consume this acid, they change the soil pH to become more alkaline, which the fungus cannot tolerate. This research shows that pH changes are just as important as removing the acid itself for controlling this pathogenic fungus in agriculture.
