Sorghum is very susceptible to damage by storage pests, the main ones being greater grain weevils, in particular the rice weevil (Sitophilus oryzae), the flour beetle (Tribolium castaneum) and the grain moth (Sitotroga cerealella).
Heavily attacked grain loses much of its content and become unfit for sale and consumption.
What to do:
- Damage can be minimised by drying grain adequately before storage. Cultivars with hard grain also suffer less damage.
