Abstract
Post-harvest losses caused by insect pests and
microorganisms represent a major challenge to global food security,
particularly in developing countries where traditional storage systems are
prevalent. It is estimated that 20–30% of harvested grains are lost annually
during storage due to insect infestation, microbial spoilage, and poor storage
infrastructure. Traditional storage structures such as earthen bins, clay pots,
bamboo containers, and underground pits play an important role in enhancing the
effectiveness of botanical protectants by maintaining favorable storage
conditions. The efficacy of herbal materials largely depends on factors such as
grain moisture content, storage duration, environmental conditions, and the
form in which botanicals are applied. Botanical protectants offer multiple
advantages over synthetic pesticides, including biodegradability, reduced
health risks, and minimal impact on non-target organisms. However, issues
related to standardization, consistency, and large-scale application remain
challenges for their widespread adoption. Overall, the integration of
traditional herbal knowledge with improved storage practices provides a
promising and sustainable approach for reducing post-harvest losses and
ensuring long-term food security. The use of plant-derived materials and herbs
for stored grain protection is a time-tested, eco-friendly alternative to
synthetic pesticides. Traditional storage practices incorporate botanical
materials such as neem, turmeric, garlic, sweet flag, tulsi, bay leaf, and
plant oils, which exhibit insecticidal, repellent, antifeedant, antifungal, and
antibacterial properties. This review synthesizes existing literature on
traditional grain storage systems, herbal pest management strategies, and the
modes of action of botanical protectants against stored grain pests and
associated microorganisms.
