use of chemical pesticides has led to the destruction of beneficial
organisms, resistance against pesticides, resurgence of treated
pests, pesticidal residues in food-chains, environmental pollution
and health disorders. In view of this, the current thrust is on
the Integrated Pest Management System (IPMS) as the main plank
of plant protection to make use of the resistant varieties, bio-control
agents and physical and cultural methods of pest control which
are more important in the context of sustainable agriculture.
IPMS encourages the use of bio-agents like predators, avoids
the use of broad-spectrum insecticides to conserve natural enemies
of insect-pests. IPMS is need-based with judicious use of pesticides
on the basis of economic threshold level (ETL) of major insect-pests
for sustainable farming.
