Abstract: This study investigates the efficacy of various storage treatments on the preservation of wheat (Triticum aestivum) and the control of the rice weevil (Sitophilus oryzae) using different plant-derived products. Conducted at the insect laboratory of the Department of Entomology, College of Agriculture, SHUATS, Prayagraj (UP), the research employed a Completely Randomized Design (CRD) with six treatments: untreated control, citrus leaves powder, Dhatura leaves powder, black pepper powder, eucalyptus oil, neem oil, and Coragen. The aim was to assess the mortality rates of rice weevils and the impact on wheat seed germination and vigor over periods of 30, 60, and 90 days. Results indicated significant differences in the effectiveness of treatments, with Coragen showing the highest mortality rates across various storage conditions, including metal containers, plastic bags, jute bags, and room heaps. Additionally, the study highlights the importance of integrating environmentally friendly plant-based products for pest control considering their biodegradability, low toxicity, and economic viability. The findings contribute to sustainable agricultural practices by offering viable alternatives to synthetic pesticides, thereby minimizing post-harvest losses and ensuring food security.
