Specific phytohormone combinations regulate plant growth and responses to environmental stimuli. Monitoring their distribution is key for understanding signaling cross-talk detecting stress early. However, typical means of monitoring these chemicals are often laborious, destructive, or limited model plants. In this study, we present an amperometric minimally invasive sensing platform that can be attached leaves the simultaneous detection two phytohormones, auxin [indole-3-acetic acid (IAA)] salicylic (SA). The incorporates magnetized microneedles coated with superparamagnetic Fe 3 O 4 intercalated into a scaffold multiwalled carbon nanotubes (MWCNTs). It achieves limits 1.41 μM (IAA) 1.15 (SA) strong correlation ( R 2 ≥ 0.7) ultrahigh-performance liquid chromatography–tandem mass spectrometry measurements. Furthermore, implementing cyclical cleaning extends sensor lifespan by preventing electrode passivation. Last, sensor’s capability monitor real-time several stressors validated, showcasing its potential phytodiagnostics precision farming.
