A Review Study on Bio Powder for Effective Control Against Storage Pest in Rice (Oryza sativa)

Abstract

Rice feeds nearly half of the global population as a staple food crop worldwide. However, rice is susceptible to various forms of deterioration during storage. Parboiled rice is relatively more resistant to spoilage, whereas non-parboiled rice deteriorates easily due to the presence of fat and its susceptibility to oxidative rancidity. One of the major challenges associated with rice is storage. Every year, about 30–50% of the total paddy production is stored by farmers, during which losses caused by storage pests pose a serious threat to rice quality and food security. To address this issue, organic methods using different plant extracts can effectively help control storage pests. Bio-powder is a plant-based formulation prepared from neem leaves (Azadirachta indica), tulsi (Ocimum sanctum), notchi (Vitex negundo), garlic bulbs (Allium sativum), and chilli fruits (Capsicum annuum). These botanicals were selected for their well-known insecticidal, repellent, and antifeedant properties. Although many studies are available on individual biorepellents derived from these plants, research on their combined use is still limited. Therefore, this review aims to create awareness among the scientific and farming communities about controlling storage pests in rice using naturally occurring plant products in the form of bio-powder.
