Plant-wearable sensors provide real-time information that enables pesticide inputs to be finely tuned and play critical roles in precision agriculture. However, tracking living plants remains a formidable challenge owing inadequate shape adaptabilities low in-field sensor sensitivities. In this study, plant-wearable hydrogel discs are designed by embedding dual-shelled upconversion-nanoparticles@zeolitic-imidazolate-framework@polydopamine (UCNPs@ZIF@PDA) composite double-network hydrogels deliver on-site pesticide-residue information. Benefiting from the enzyme-mimetic catalytic activity of ZIFs enzyme triggered-responsive property PDA shell, endowed with high sensing sensitivity toward 2,4-dichlorophenoxyacetic acid at nanogram per milliliter level via boosting fluorescence quenching efficiency. Notably, mounted on tomato exhibit sufficient adaptability profile dynamic degradation when used conjunction an ImageJ processing algorithm, which is practically applicable. Such form noninvasive low-cost toolkit for acquisition information, thereby contributing precise management health status plant judicious development
