Although agrochemical practices can enhance agricultural productivity, their intensive application has resulted in the deterioration of ecosystems. Therefore, it is necessary to develop more efficient and less toxic methods against pests infections while improving crop productivity. Moving toward sustainable development, this work, we originally described preparation a composite (ZIF-8@HA) consisting coating zeolitic-like metal-organic framework (MOF) ZIF-8 (based on Zn, an essential micronutrient plants with antibacterial, antifungal, antifouling properties) hydroxyapatite (HA) nanoparticles (i.e., nanofertilizer). The interaction between HA been characterized through combination techniques, such as microscopic where presence demonstrated; or by analysis surface charge dramatic change Z-potential (from +18.7 ± 0.8 -27.6 0.7 mV for ZIF-8@HA, respectively). Interestingly, delays MOF degradation 4 h pristine 168 HA-coated material), providing slower gradual release zinc. After comprehensive characterization, potential combined fertilizer bactericidal effect ZIF-8@HA was investigated wheat (Triticum aestivum) seeds Pseudomonas syringae (Ps). (7.3 ppm) demonstrated great effect, increasing shoot (9.4 %) root length (27.1 after 11 days at 25 °C under dark conditions, results obtained HA, ZIF-8, ZnSO4 even physically mixed constituents (HA + ZIF-8). It also effective growth inhibition (>80 % inhibition) Ps, vegetal pathogen causing considerable decline. work demonstrates MOF@HA composites paves way promising improved antibacterial properties.
