**4.8 Judicious insecticidal use**

Use of synthetic insecticides is the last option in IPM programs, while even the use of different botanicals and other bio pesticides are also avoided to spray in early cotton season, thus the beneficial insects could be conserved. But when the pest population exceeds to economic threshold level, then by relying and designing the appropriate time and schedule of applying sprays only with selective chemicals according to their minimal impact on non-target could help to conserve beneficial insects. Avoidance by blind sprays could also help in IPM program, because the spot treatments within field could conserve natural environment for beneficial insects.
