प्रश्न
Describe the various methods of controlling pests attacking stored grains.
उत्तर
The following two methods are used to control pest attack on the stored food grains:
1. Chemical control: The pesticide solution is sprayed over the gunny bags containing food grains by using a manual sprayer or a mechanical sprayer.
2. Fumigation: Fumigants (pesticides that destroy insects) react with moisture of the air forming poisonous fumes that kill the pests. This is the most effective method of destroying insects in stored food grains.
