Comparative Antagonistic Activities of Endolichenic Fungi Isolated from the Fruticose Lichens Ramalina and Usnea

mycolabadmin

Researchers studied fungi living inside lichen plants from the Philippines to see if they could help fight crop diseases. They tested 40 different fungi against three harmful pathogens that destroy important crops. The results showed that these lichen-dwelling fungi were effective at stopping pathogen growth, with fungi from Ramalina lichens performing better than those from Usnea lichens. This discovery suggests a natural, eco-friendly way to protect crops without harsh chemicals.

The Biocontrol and Growth-Promoting Potential of Penicillium spp. and Trichoderma spp. in Sustainable Agriculture

mycolabadmin

This review explores how two common fungi, Penicillium and Trichoderma, can help crops grow better and resist diseases naturally. These beneficial fungi live in plant roots and soil, providing nutrients, protecting against harmful pathogens, and helping plants cope with environmental stress. They offer an environmentally friendly alternative to chemical pesticides and fertilizers, making them valuable for sustainable agriculture.

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.

Effect of Pseudomonas protegens EMM-1 Against Rhizopus oryzae in Interactions with Mexican Autochthonous Red Maize

mycolabadmin

Mexican red maize, an important traditional crop, is threatened by a fungus called Rhizopus oryzae that causes root damage and wilting. Researchers found that a beneficial bacterium, Pseudomonas protegens EMM-1, can effectively stop this fungal infection and help maize plants grow better. Tests showed the bacterium reduced fungal growth by over 80% and improved plant root development when grown together with the fungus.

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.

Volatile Semiochemicals Emitted by Beauveria bassiana Modulate Larval Feeding Behavior and Food Choice Preference in Spodoptera frugiperda (Lepidoptera: Noctuidae)

mycolabadmin

Researchers discovered that a beneficial fungus called Beauveria bassiana produces odorous chemicals that can discourage pest insects from eating crops. When certain strains of this fungus release their characteristic smell (particularly a compound called 3-methylbutanol), larvae of the fall armyworm pest eat less and avoid treated plants. Interestingly, the plants themselves respond by producing defensive compounds when exposed to these fungal odors. This finding suggests a new approach to pest control that harnesses the natural chemical communication between fungi, plants, and insects.

2-Nonanol produced by Bacillus velezensis EM-1: a new biocontrol agent against tobacco brown spot

mycolabadmin

Researchers discovered that a beneficial bacterium called Bacillus velezensis produces a natural compound called 2-nonanol that effectively kills the fungus causing brown spots on tobacco leaves. This compound works by disrupting the fungus’s ability to obtain energy and handle stress. Testing on tobacco leaves showed that 2-nonanol could significantly reduce disease development. This discovery offers a promising environmentally-friendly alternative to chemical fungicides for protecting tobacco crops.

Antifungal Volatile Organic Compounds from Talaromyces purpureogenus CEF642N: Insights from One Strain Many Compounds (OSMAC) Strategy for Controlling Verticillium dahliae in Cotton

mycolabadmin

Scientists discovered that a beneficial fungus called Talaromyces purpureogenus produces natural antifungal compounds that effectively control cotton wilt disease caused by the harmful fungus Verticillium dahliae. The study identified two main compounds, 3-octanol and 2-octenal, that showed strong antifungal activity without synthetic chemicals. This research offers a promising green alternative for protecting cotton crops from one of agriculture’s major diseases while being environmentally friendly.

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.

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.
