Is integrated pest management effective at large agricultural scales?

Who benefits most from IPM at large scales?

IPM works best on medium-scale farms, not the very largest. A 2023 study of mango farmers in Kenya found that all IPM practices—like using parasitoids, sanitation, and bait sprays—were profitable, but the highest returns went to medium-scale farmers (with 9–17 trees). Large-scale farmers with more than 320 trees saw little to no economic benefit [6]. The male annihilation technique was the most profitable practice overall, with a value-cost ratio of 36, meaning every dollar spent returned $36 in benefits [6]. This suggests that IPM's labor-intensive monitoring and targeted treatments become less cost-effective as farm size grows beyond a certain point.

For large-scale operations, IPM can still work if combined with modern tools. A 2024 review highlights that new biopesticides and targeted delivery systems, like nanoemulsions, can improve efficacy and reduce off-target impacts, making IPM more feasible for large farms [7]. Additionally, a 2025 study on biopesticides notes that branded formulations are more common on large-scale farms, which have the economic capacity to invest in them [4]. So, while IPM is not a one-size-fits-all solution, large farms can adopt it successfully by integrating advanced technologies.

What makes IPM work at scale?

Cooperative structures and social networks are key drivers. A 2026 study of kiwifruit growers in China found that farmers who joined new agricultural operating entities (like cooperatives) were significantly more likely to adopt IPM, thanks to price premiums, risk sharing, and quality supervision [3]. Similarly, a 2022 study on citrus growers in China showed that social capital within cooperatives—trust and shared knowledge—boosted IPM adoption, with over 51% of the effect coming from improved understanding of IPM [10]. This means that large-scale adoption often depends on collective action, not just individual farmer decisions.

Technology also bridges the gap. A 2025 review on biosurfactants and nanotechnology argues that integrating these innovations with IPM can improve biopesticide stability and targeted delivery, reducing the environmental footprint and making IPM more practical for large-scale deployment [1]. For example, baculoviruses—natural viruses that kill pests—have been used successfully on millions of hectares of soybeans in South America, with a new isolate showing superior potency against cotton leafworm, a major pest [2]. This demonstrates that biological control agents can be scaled up effectively when backed by research and infrastructure.

What are the caveats and limitations?

IPM is not always profitable for the largest farms. The Kenya mango study found that farmers with over 320 trees saw little economic benefit from IPM, and the reasons remain unclear—possibly due to higher labor costs or lower pest pressure per tree [6]. This means that very large operations may need to combine IPM with mechanization or precision agriculture to maintain profitability.

Large-scale farming can also increase carbon emissions. A 2023 study on Chinese agriculture found that both mechanization and large-scale operations initially increase carbon emissions, though large-scale farming reduces emissions in the long run [9]. This suggests that scaling up IPM must be paired with sustainable practices, like clean-energy machinery, to avoid environmental trade-offs.

Finally, adoption barriers remain. A 2022 review on bivalve aquaculture notes that IPM has not been broadly applied in aquaculture due to data gaps and lack of guiding frameworks, though principles from terrestrial agriculture offer a strong foundation [5]. Similarly, a 2023 review on agroecology stresses that large-scale adoption requires integrated policies and economic viability for farmers [8]. So, while IPM is effective, its success at scale depends on context, support systems, and ongoing innovation.
