Trichoderma or Green Mold is a soil dwelling fungi found all over the world that causes problems in sterile mushroom farms. If a mushroom block has green mold growing on it, it’s not a loss. It actually benefits plants in the following ways:
Root Development: Trichoderma produces growth-promoting hormones like indole acetic acid (IAA), which stimulate root growth, leading to a more extensive and healthy root system. This allows trees to access more water and nutrients.
Enhanced Nutrient Uptake: Trichoderma forms a symbiotic relationship with tree roots, enhancing the absorption of nutrients, especially nitrogen, phosphorus, and essential micronutrients. This promotes better tree growth and vigor.
Disease Suppression: Trichoderma helps trees fight off pathogens by parasitizing harmful fungi and secreting enzymes that break down pathogen cell walls. This protects the tree from diseases, allowing it to grow without stress.
Stress Resistance: It boosts the tree's ability to withstand abiotic stresses like drought and salinity by producing compounds that enhance the plant’s stress tolerance mechanisms.
Soil Health: Trichoderma improves soil structure and fertility by breaking down organic matter and promoting microbial diversity, creating a better growing environment for trees.
