Abstract

Smart nutrient management is emerging as a cornerstone of integrated pest and disease control in tropical fruit crops such as papaya and banana. This review aims to explore how nutrient imbalances, particularly excessive nitrogen, influence pest outbreaks and plant resilience. Drawing on Mulder’s chart (Martín-Cardoso & San Segundo, 2025) of nutrient interactions, we examine the antagonistic effects of surplus nitrates on potassium uptake. The paper synthesizes data from recent studies and field-based insights, highlighting smart pest control strategies including real-time nutrient diagnostics and intelligent monitoring systems. These approaches offer practical tools for growers in northern Australia and support sustainable farming practices. The role of AI technologies in shaping future pest management is also discussed.

    This paper has the following pros and cons:

    Pros

    • Highlights the link between nutrient management and pest/disease susceptibility in tropical fruit crops.

    • Strong emphasis on sustainability and reducing chemical dependency.

    • Integrates advanced technologies (AI, sensors, deep learning) with agronomy practices.

    • Provides practical case studies (papaya, banana) relevant to tropical agriculture.

    • Promotes climate-smart pest management frameworks in line with global sustainability goals.

    • Acknowledges both biological control and agroecological approaches as complements to smart technologies.

    Cons

    • Heavy reliance on secondary literature rather than new experimental data.

    • Strong focus on Australian context, which may limit broader applicability.

    • Adoption challenges (cost, accessibility, farmer training) not deeply addressed.

    • Limited discussion of economic feasibility for smallholder farmers.

    • Technological optimism may overlook infrastructural and policy barriers.
