The preparation of a novel nanoscale imazalil (IMZ)-based coordination polymer [Zn(HBTC)(IMZ)₂]_n (PDCP1) (H₃BTC = 1,3,5-benzenetricarboxylic acid), and its antifungal application within a sustainable delivery system was reported. The intermolecular interactions presented in the structure, and their contributions to crystal packing were studied by Hirshfeld, Fingerprint plot and Mayer bond order. The obtained PDCP1 had a relatively high loading rate of IMZ (68.5%). PDCP1 exhibited notable antifungal activities against Colletotrichum gloeosporioides, Magnaporthe Oryzae, and Alternaria Nees strains, with EC₅₀ values of 0.72, 0.92, and 0.56 µg/mL, respectively. The key benefits of the application of PDCP1 as a control release pesticide include high fungicide loading and offer nearly complete release, pH-responsive release, enhanced UV stability, exhibits favorable biosafety profiles. The remarkable inhibition of C. gloeosporioides growth by PDCP1 underscores a promising strategy for agrochemical material development, high loading of active ingredients and readily delivery fosters more efficient pesticides utilization in agricultural processes.
