Trichoderma harzianum has proved a useful micro-organism for
  1. bioremediation of contaminated soils
  2. reclamation of wastelands
  3. gene transfer in higher plants
  4. biological control of soil-borne plant pathogens

Solution

Some common fungal inhabitants of soil help to combat diseases caused by soil borne fungi. Trichoderna tignorum and Glocladium fimbriatum are found in damp soils. They have an inhibitory effect on the growth of the mycelium of pythium. They serve to supress fungi causing damping off disease of the seedlings and thereby influence favourably the growth of crops.
