D. biological control of soil-borne plant pathogens
Step-by-step 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.
