therapeutic action: promotion of plant growth

Microsclerotia formation of the biocontrol fungus Cordyceps javanica IF-1106 and evaluation of its stress tolerance and pathogenicity

mycolabadmin

Researchers studied a fungus called Cordyceps javanica that can be used to control harmful soil nematodes that damage crop roots. The fungus produces special dormant structures called microsclerotia that can survive extreme heat and UV radiation for extended periods. These microsclerotia showed excellent effectiveness at controlling root-knot nematodes on cucumber plants while also promoting plant growth, making them a promising natural alternative to chemical pesticides.

Biocontrol efficacy of Pochonia chlamydosporia against root-knot nematode Meloidogyne javanica in eggplant and its impact on plant growth

mycolabadmin

This study shows that a beneficial fungus called Pochonia chlamydosporia can effectively control harmful root-knot nematodes that damage eggplant crops. When applied to soil, this fungus directly attacks nematode eggs and parasitizes the parasitic juveniles, while also boosting the plant’s natural defense systems. Not only does the fungus reduce nematode populations by over 55%, but it also helps eggplant plants grow better with increased height, weight, and chlorophyll content, providing a promising eco-friendly alternative to chemical pesticides.

Biocontrol of Root-Knot Nematodes via siRNA-Loaded Extracellular Vesicles From a Nematophagous Fungus Arthrobotrys oligospora

mycolabadmin

Scientists developed a new way to control harmful root-knot nematodes that damage crops by using natural containers called extracellular vesicles from a fungus. These vesicles carry small RNA molecules that silence genes essential for nematode survival and reproduction. When tested on tomato plants, this fungal-based treatment reduced nematode damage by about 60% while promoting healthier plant growth, offering an eco-friendly alternative to chemical pesticides.

Inhibition of RNase to Attenuate Fungal-Manipulated Rhizosphere Microbiome and Diseases

mycolabadmin

A fungal pathogen that causes root rot in soybeans and other crops uses a toxic protein called Fg12 to kill beneficial bacteria in the soil that would otherwise protect plants. Scientists discovered that guanosine monophosphate (GMP), a simple chemical compound, can block this toxic protein. When applied to soil, GMP protects plants by allowing beneficial bacteria to survive and fight the fungal infection.

Inhibition of RNase to Attenuate Fungal-Manipulated Rhizosphere Microbiome and Diseases

mycolabadmin

Fusarium fungi cause devastating crop diseases by producing a protein called Fg12 that acts like a molecular weapon to kill beneficial bacteria in the soil around plant roots. Scientists discovered that a simple compound called GMP can block this fungal weapon, preventing the pathogen from suppressing protective bacteria. By treating seeds or soil with GMP, farmers can significantly reduce root rot in soybeans and alfalfa while promoting plant growth.

Identification of a Novel Pathogen of Peanut Root Rot, Ceratobasidium sp. AG-A, and the Potential of Selected Bacterial Biocontrol Agents

mycolabadmin

Scientists in China discovered a new fungal disease causing peanut root rot, identified as Ceratobasidium sp. AG-A. They tested three types of beneficial bacteria as natural pest control agents and found they effectively inhibited the disease-causing fungus while promoting peanut plant growth. These findings offer farmers an environmentally friendly alternative to chemical fungicides for managing this newly identified threat to peanut crops.
