Bioinspired nano-architected chitosan-β-glucan nanocomposite as an elicitor for disease management sustainably

mycolabadmin

Scientists created tiny engineered particles made from chitosan and β-glucan that act like alarm signals to boost plants’ natural defenses against a destructive soil fungus called Sclerotium rolfsii. These nano-particles are extremely effective at just 220-240 parts per million, far more powerful than conventional fungicides which require 2000 ppm. The particles work by damaging the fungus’s cells directly while also triggering the plant’s immune system, offering farmers a sustainable alternative to chemical pesticides.

Roles of arbuscular mycorrhizal fungi in plant growth and disease management for sustainable agriculture

mycolabadmin

Arbuscular mycorrhizal fungi are beneficial fungi that live in plant roots and form a mutually beneficial relationship with plants. These fungi help plants absorb more nutrients and water from the soil, strengthen their natural defenses against diseases and pests, and work together with other helpful soil bacteria to create disease-suppressive soil. This makes AMF a promising natural alternative to chemical pesticides and fertilizers for sustainable agriculture.

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.

Evaluation of Streptomyces sporoverrucosus B-1662 for biological control of red pepper anthracnose and apple bitter rot diseases in Korea

mycolabadmin

This research evaluated a naturally occurring bacterium called Streptomyces sporoverrucosus B-1662 as a biological alternative to chemical fungicides for controlling fungal diseases on red peppers and apples. Laboratory and field tests demonstrated that this bacterium can reduce disease symptoms by over 90%, making it a promising option for organic farmers seeking to protect their crops without synthetic chemicals. The study identified the specific compound responsible for the bacterium’s effectiveness and provided detailed information about its genetic makeup.

Luobuma Leaf Spot Disease Caused by Alternaria tenuissima in China

mycolabadmin

Researchers in China identified a serious fungal disease affecting Luobuma plants (used for tea, medicine, and textiles) caused by the fungus Alternaria tenuissima. The disease caused leaf spots that spread rapidly, with infection rates reaching 95% in some plants. Testing showed that a fungicide called hymexazol was effective at controlling the disease, offering farmers a practical solution for protecting their 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.

Synergistic curative effects of Trichoderma hamatum and Rumex dentatus against Alternaria alternata, the causal agent of tomato leaf spot disease

mycolabadmin

This research discovered that combining a beneficial fungus called Trichoderma hamatum with an extract from Rumex dentatus plant effectively controls tomato leaf spot disease. When used together, these natural treatments reduced disease by over 88% and even outperformed commercial fungicides. The combined treatment also boosted plant health by increasing growth and natural defense mechanisms, offering farmers an affordable and environmentally safe alternative to chemical pesticides.

Antifungal activities of Rosmarinus extracts against Fusarium oxysporum, the pathogenic fungus of Anoectochilus stem rot

mycolabadmin

Researchers found that extracts from rosemary plants can effectively fight a fungus that causes stem rot disease in Anoectochilus, a valuable medicinal herb. The rosemary extracts worked both in laboratory tests and when applied to infected plants, reducing disease symptoms and boosting the plant’s natural defense mechanisms. These findings suggest rosemary extracts could be developed as a natural, safer alternative to synthetic chemical fungicides that harm the environment.

Bacterial community shifts in Fusarium-induced avocado root rot and the antagonistic potential of Bacillus siamensis NB92

mycolabadmin

Avocado plants are threatened by a fungal disease called root rot that damages roots and reduces fruit production. Researchers discovered that when avocado roots become diseased, the beneficial bacteria in the soil around the roots decrease significantly. They isolated a beneficial bacterium called Bacillus siamensis NB92 from healthy avocado soil that can fight against the disease-causing fungus by producing special compounds. When applied to diseased soil, this bacterium reduced the fungal pathogen and protected avocado stems from damage, offering a natural alternative to chemical treatments.

Bioprospecting and mechanistic insights of Trichoderma spp. for suppression of Ganoderma-induced basal stem rot in oil palm

mycolabadmin

Scientists discovered that a fungus called Trichoderma afroharzianum can effectively fight a serious disease in oil palm trees caused by another fungus, Ganoderma. This beneficial fungus works by producing natural chemicals and enzymes that kill the harmful pathogen and also helps the plants grow better. The research shows this could be used as an eco-friendly alternative to chemical pesticides for protecting oil palm plantations, especially as climate changes and farming conditions vary.
