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.

The influence of intercropping Paris polyphylla with Polygonatum cyrtonema or Ganoderma lucidum on rhizosphere soil microbial community structure and quality of Paris polyphylla

mycolabadmin

Researchers studied how planting Paris polyphylla (a rare medicinal plant) together with other plants affects soil health and medicine quality. Growing P. polyphylla alone caused problems like soil nutrient depletion and harmful microorganism growth. When grown alongside Ganoderma lucidum mushrooms or Polygonatum cyrtonema plants, the soil became healthier with better nutrients and beneficial microorganisms. This resulted in higher yields and better quality medicinal compounds in the P. polyphylla.

Actinomycetes isolated from rhizosphere of wild Coffea arabica L. showed strong biocontrol activities against coffee wilt disease

mycolabadmin

Researchers discovered that certain bacteria called actinomycetes, particularly a strain called MUA26, can effectively fight coffee wilt disease, a serious fungal infection that damages coffee plants. These beneficial bacteria produce natural compounds that kill the disease-causing fungus and were tested on coffee seedlings in a greenhouse, showing 83% effectiveness at preventing the disease. This discovery offers coffee farmers an organic alternative to chemical pesticides, which are expensive and harmful to the environment.

Soil microorganism colonization influenced the growth and secondary metabolite accumulation of Bletilla striata (Thunb.) Rchb. F.

mycolabadmin

Chinese ground orchid (Bletilla striata) is a medicinal plant whose growth and medicinal compound production depend heavily on soil microorganisms. Researchers found that different soil types harbor different beneficial microbes: sandy loam soils boost plant growth, while sandy clay soils increase medicinal compound concentration. Specific microbes colonize different plant parts, with some promoting growth in roots and tubers, while others enhance the production of militarine, a compound with potential anti-aging and cognitive benefits.

Apple replant disease: unraveling the fungal enigma hidden in the rhizosphere

mycolabadmin

Apple orchards that are replanted in the same location often develop a disease that stunts growth and can kill young trees. Scientists discovered that harmful fungi, especially Fusarium species, grow excessively in the soil around diseased trees. These harmful fungi appear to be the main culprits behind the disease. The study identified specific fungicides that can control these pathogenic fungi, offering hope for preventing the disease in future plantings.

Streptomyces-Based Bioformulation to Control Wilt of Morchella sextelata Caused by Pestalotiopsis trachicarpicola

mycolabadmin

Researchers discovered two beneficial bacteria called Streptomyces that can protect morel mushrooms from a harmful fungus causing wilt disease. When applied to morel cultivation fields, these bacteria not only prevented disease but also increased mushroom yields by about 30% compared to untreated fields. This natural biocontrol approach offers farmers an eco-friendly alternative to chemical treatments while boosting their harvests.

Strain and contact-dependent metabolomic reprogramming reveals distinct interaction strategies between Laccaria bicolor and Trichoderma

mycolabadmin

This research explores how two types of soil fungi interact with each other through chemical signals. When Trichoderma (a beneficial biocontrol fungus) encounters Laccaria bicolor (a helpful fungus that aids plant growth), they communicate through airborne volatile compounds and secreted chemicals. The study found that these fungi employ different strategies depending on how close they are to each other, changing their chemical production to either compete or coexist, which has implications for improving agricultural biocontrol applications.

Phosphorus-solubilizing fungi improve growth and P nutrition in sorghum at variable salinity levels

mycolabadmin

Researchers discovered five types of salt-tolerant fungi that help plants absorb phosphorus even in salty soils. When these fungi were applied to sorghum plants grown in salt-affected soils, the plants grew better and absorbed more phosphorus. The most effective fungus, Penicillium oxalicum, worked by releasing organic acids and other compounds that made phosphorus more available to plants. This discovery offers a promising natural alternative to chemical fertilizers for farming in salt-affected regions.

Biocontrol Potential of Trichoderma Ghanense and Trichoderma Citrinoviride toward Pythium aphanidermatum

mycolabadmin

Researchers identified two native Trichoderma fungi species that can protect cucumber plants from a destructive soil disease caused by Pythium. In laboratory and greenhouse tests, these beneficial fungi blocked pathogen growth and significantly improved plant survival and growth compared to untreated plants. These findings suggest these natural fungi could replace harmful chemical fungicides for protecting cucumbers and other crops.

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.
