Trichoderma spp. are fungi that are present in nearly all soils and other diverse habitats. Trichoderma are known for their production of several lytic enzymes and , among them T. viride and T. harzianum are commercialized. used Phosphobacteria is Bacillus megaterium.
Trichoderma fungus is well known for disease and nematode control of crop plants. Trichoderma controls diseases by the production of several lytic enzymes and controlling disease causing microbes.
Trichoderma controls nematode infestation by feeding on infective nematodes.
These fungi compete with other disease causing microbes for nutrients and space.These fungi increase the rate of plant growth and development, by developing more robust roots. These deep roots cause crops, such as corn, and ornamental plants, to become more resistant to drought.
Trichoderma also solubilizes phosphates and micronutrients.
Trichoderma harzianum produces enzymes such as protease which controls Botrytis cinerea. Trichoderma are also helpful in solubilization and sequestration of inorganic nutrients.
