- Deep ploughing during summer to expose the hibernating pupae to adverse weather conditions and natural enemies.
- Mixing of sorghum/maize seeds (250 g/ha) to function as live bird perches. These plants also help in conserving natural enemies.
- Installation of pheromone traps @ 5/ha.
- Application of HaNPV @ 250 LE/ha.
- Spraying of botanical insecticide – Neem 1500 ppm @ 2000 ml/ha.
- Manual picking/ collection of blister beetles using insect nets and destroys them.
- Spraying of synthetic pyrethroids, Cypermethrin @ 1ml/litre protects the crop from Beetle damage.
- Application of Spinosad or imidacloprid gives control upon pod bug damage.
- Spraying of quinalphos 25% EC @ is effective against pod fly and pod borer.
- Spray ovicide – Profenophos 50 EC @ 2000 ml/ ha.
- Spraying of effective molecule like Indoxacarb 14.5 SC % @ 300 ml/ha or Emamectin benzoate 5% SG @ 11 a.i gm/ha or Spinosad 45 SC @ 56-73 a.i gm/ha is effective against Pod borer complex.
