उत्तर
- Let the grain dry in the sunlight. The harsh sunlight does not allow eggs and caterpillars to grow in the grain.
- Keep dried neem leaves in the container in which the grains are stored. Neem acts as a repellent for insects.
- Grains like beans are smeared with mud. The mud particles keep the weevils away from infesting the grains.
- The place where grain is stored should be cool and dry. It should be airy. The chances of insect infestations are less in such storage places.
