For survival and quality of life, human society has sought more productive, precise, and sustainable agriculture. Agrochemistry, which solves farming issues in a chemical manner, is the core engine that drives the evolution of modern agriculture. To date, agrochemistry has utilized chemical technologies in the form of pesticides, fertilizers, veterinary drugs and various functional materials to meet fundamental demands from human society, while increasing the socio-ecological consequences due to inefficient use. Thus, more useful, precise, and designable scaffolding materials are required to support sustainable agrochemistry. Reticular chemistry, which weaves molecular units into frameworks, has been applied in many fields based on two cutting-edge porous framework materials, namely metal–organic frameworks (MOFs) and covalent-organic frameworks (COFs). With flexibility in composition, structure, and pore chemistry, MOFs and COFs have shown increasing functionalities associated with agrochemistry in the last decade, potentially introducing reticular chemistry as a highly accessible chemical toolbox into agrochemical technologies. In this critical review, we will demonstrate how reticular chemistry shapes the future of agrochemistry in the fields of farm sensing, agro-ecological preservation and reutilization, agrochemical formulations, smart indoor farming, agrobiotechnology, and beyond.

Herein, we introduce our recent finding that a copper selenide submicron particulate film supported on an underlying Cu foam (Cu2Se SPs/CF) via an in situ facile chemical vapor deposition process could be well utilized for glucose sensing. This monolithic electrode shows excellent catalytic activity toward glucose with an ultrahigh sensitivity (18 660 μA mM−1 cm−2), a low determination limit (LOD) of 0.25 μM, a fast response time of 3 s and good selectivity, which is much superior to almost all reported Cu-based sensors. It also shows good reproducibility and feasibility in glucose detection in diluted human serum samples. This good performance could be attributed to the overall good catalytic activity of both the Cu2Se phase and Cu foam, the high surface area provided by the unique submicron particulate-formed Cu2Se film, and good conductivity of the integral Cu2Se SPs/CF.
