  • bioremediation of contaminated soils

  • reclamation of wastelands

  • gene transfer in higher plants

  • Biological control of soil-borne plants pathogens

Answer

D.

Biological control of soil-borne plants pathogens

Some common fungal inhabitants of soil help to combat diseases caused by soil-borne fungi. Trichoderma lignorum and Gliocladium fimbriatum are found in damp soils. They have an inhibitory effect on the growth of the mycelium of pythium. They serve to suppress fungi causing damping off disease of the seedings and thereby influence favourably the growth of crops.
