In traditional grain storage, farmers often mix grains with neem leaves to prevent:
Moisture absorption
Germination
Loss of nutrients
Insect infestation
Insect infestation
In traditional agriculture, farmers commonly blend dry neem leaves with stored food grains to prevent insect infestation. Neem (Azadirachta indica) possesses natural pest-repellent, antifungal, and insecticidal properties that deter storage pests like weevils and beetles without resorting to synthetic chemical pesticides.

Geography & Agriculture: Traditional Agricultural Practices and Botanical Pesticides (Neem compound: Azadirachtin)
Azadirachtin is the primary active limonoid compound in neem that acts as a potent antifeedant, repellent, and insect growth regulator.
Dried neem leaves are mixed with grains in air-tight containers or jute bags in traditional storage systems across India.
Using neem leaves is a traditional biological pest management technique that leaves no toxic chemical residue on food grains.
Neem (Azadirachta indica) belongs to the Meliaceae family and is widely acknowledged in Ayurveda for its antibacterial, antifungal, and pesticide properties.
Option A (Moisture absorption) is incorrect because dried leaves do not act as primary desiccant agents (like silica gel or sun-drying).
Option B (Germination) is incorrect because seed germination is controlled primarily by moisture and temperature levels, not neem leaves.
Option C (Loss of nutrients) is incorrect as nutrient loss during storage occurs due to humidity, fungal rot, or oxidation, not prevented directly by neem.
D is correct — Traditional storage uses dry neem leaves specifically to repel and prevent insect infestations in food grains.
Questions on eco-friendly pest control and traditional agricultural techniques frequently overlap with Biology (Biopesticides) and Environmental Studies in exams like RRB ALP, SSC, and State PSCs.
