Their rapid degradation in the environment minimized harmful residues in soil and water, protecting ecosystems from the long-term damage associated with chemical pesticide use. This is especially important in regions like India, where water and soil quality are critical for sustainable agriculture. The study also found that biopesticides had minimal impact on non-target organisms, including beneficial insects, pollinators, and soil microbes, helping to maintain biodiversity and ecological balance in the treated areas (Bateman et al., 2021). Moreover, the use of biopesticides contributed to reducing greenhouse gas emissions in agricultural practices. Unlike the production and application of chemical pesticides, which are energy-intensive and emit significant amounts of carbon dioxide, biopesticides are produced through more sustainable processes. The lower carbon footprint of biopesticide use supports global efforts to mitigate climate change, aligning with sustainable agriculture goals and contributing to the development of eco-friendly farming practices (Gupta et al., 2023). 5.4 Lessons learned and future recommendations This study provided several key lessons regarding the integration of biopesticides into maize IPM systems. First, the timing of biopesticide application was crucial to their success. Given their slower action compared to chemical pesticides, farmers must carefully monitor pest populations and apply biopesticides at the optimal time to prevent pest outbreaks. Second, the study highlighted the importance of developing biopesticides that are more resilient to environmental conditions, particularly in regions with extreme climates. Future research should focus on improving the formulation and stability of biopesticides to enhance their effectiveness in a wider range of conditions (Hernandez-Tenorio et al., 2022). In addition to technological improvements, the study emphasized the need for farmer education programs to ensure the correct use of biopesticides. Training programs should focus on teaching farmers the best application methods and informing them of the long-term environmental and economic benefits of biopesticides. With better understanding, farmers are more likely to adopt biopesticides as part of their IPM strategies. Government policies also play a critical role in promoting biopesticide use. Financial incentives, such as subsidies and tax breaks, could help reduce the costs of biopesticides, making them more accessible to smallholder farmers (Bateman et al., 2018). In the future, we will further enhance the synergistic effects with other IPM technologies in the application of biopesticides, such as crop rotation and plant resistance enhancement, to achieve a more comprehensive and sustainable pest management plan. This can not only improve the long-term effectiveness of pest control, but also reduce the resistance of pests to a single control method, promoting sustainable agricultural development. 6 Future Directions and Innovations 6.1 Advances in biopesticide formulation and delivery Recent advancements in the formulation and delivery of biopesticides are aimed at enhancing their stability, effectiveness, and ease of application. A key challenge with biopesticides has been their sensitivity to environmental conditions like temperature and UV exposure, which can reduce their efficacy. Advances in encapsulation technologies, such as nanoencapsulation, have helped improve the stability of biopesticides by protecting the active ingredients from environmental degradation. Nanoencapsulation can also provide controlled-release capabilities, ensuring that the biopesticide is released over time to maintain longer-lasting protection against pests (Gupta et al., 2023). Another promising innovation is the development of dry powder formulations and seed treatments that simplify the application of biopesticides. These formulations allow farmers to apply biopesticides using conventional seed treatment or spraying equipment, reducing the labor and complexity associated with liquid biopesticide formulations. Dry formulations also improve shelf life, which is crucial for distribution in regions with limited cold storage facilities (Bateman et al., 2021). Additionally, researchers are exploring biopesticide combinations that include multiple microbial agents, each targeting different stages of a pest’s lifecycle. These synergistic formulations improve pest control effectiveness while minimizing the risk of pest resistance. As research continues, these innovations in biopesticide formulation and delivery are expected to further enhance their role in Integrated Pest Management (IPM) (Soetopo and Alouw, 2023).
