rhizobacteria are naturally occurring bacteria found in the root environment of plants. They form a symbiotic relationship with the plant, aiding in nutrient uptake and enhancing overall plant health. Trichoderma, on the other hand, is a fungus that often grows from plant roots. It's known for its ability to protect plants from harmful pathogens and promote root growth.
