3.  Bio Control Agents:-
 Bio Control Agents are efficient microorganisms
that controls plant pest . These are specific to the
plant insect and are co-friendly in nature. It also
induces systemic resistance in crop plants.
 Ex. Parasite , predator and parasitoid etc.
 Improving Efficiency of Bio-agent:-
 If it is manipulated in favour of bio-agent. It become
determinate to pest survival and its activity.
Biological control often fails due to lack of through
understanding between bio-agent pest host
environment interactions and their impact on
disease development.

4. Charcharstic of bio agents:-
 Good searching capacity at high and low
density.
 Self dispersing and propagating ability.
 Effective and well adopted to climatic condition.
 High reproductive capacity with short
generation.
 The bio control agent be resistance to
hyperparasitism and multiparasitism .

5. Improving Efficiency of bio agents:-
 Use of bio agents right time (evening time).
 Providing supplementary foods.
 Use right place ex. Trico cord in shade
lower surface of leaf because sensitive to
direct sunlight.
 Right combination with chemical having
spray.
 Should be apply right types of culture
practices in the field during presence of bio-
agent in the field.

6. Moisture &temperature :-
 Moist soil relative humidity is 60-80% for
survival of bio agents. Optimum
temperature range of bio agents 25-30ºC.
Limitation and future Thrusts:-
The effective amount of bio-agent needed to be
incorporated to contact the pest large quantity and
can not be achieved unless the antagonist
establish it self in the ecosystem and multiplies.

7.  There is a need to educate the dealers and
the growers on storage condition, shelf life
and mode of action of bio control.
 A grower who is tuned to a rapid results
obtained with chemical pesticide, need to
explained of slower but sustainable
response by the bio control agents besides
the environmental safety and other positive
effects of microbes on plant and soil.
