“…The infrared spectra of ZIF-8, ZIF-8@PMMA, and ZIF-8@PMMA/zein were recorded in Figure a. The peaks at 1585 and 2929 cm –1 were assigned to the CN and C–H stretching vibrations of imidazole, respectively, and the peaks that appeared at 1417 and 985 cm –1 were attributed to the stretching of C–N bond. , In the spectrum of ZIF-8@PMMA, a new adsorption peak at 1731 cm –1 was ascribed to the stretching vibration of carbonyl (−CO) groups in PMMA . After the coating of zein, the characteristic peak of the amide group (−CONH−) appeared at 1660 cm –1 .…”

“…The supernatant (5 mL) was collected at designated intervals and replenished with the same PBS solution. The cumulative release percentage (CRP %) of DNF or Zn 2+ was calculated as the following eq where V total was the total volume of the phosphate buffered saline solution, V t and C t were the volume and concentration of pesticide or Zn 2+ at time t , respectively. m 0 (mg) was the weight of DNF or Zn 2+ in the MOF hybrid.…”

Advanced intelligent systems for delivery of pesticides or fertilizers require formulations that allow for long-term efficacy. In this work, a metal–organic framework (MOF) hybrid was developed for long-term pest management and micronutrient supply. Zeolitic imidazolate framework-8 was fabricated for crop micronutrients (Zn2+) supply and insecticide dinotefuran (DNF) encapsulation. Polymethylmethacrylate was polymerized in situ to impart the MOF hybrid with sustained cargo delivery. Then, zein was introduced to facilitate protease-triggered cargo release associated with the microenvironment of pests and targeted release. The resulting MOF hybrid exhibited stimulus-responsive, slow-release behaviors. Sustained DNF delivery was achieved over a period of at least 32 days in soil. Compared with that of free DNF, the UV resistance of DNF in the MOF hybrid increased by nearly 10 times, and the insecticidal efficiency increased 33.3% with leaching treatment and 40.1% after incubating in a greenhouse for 14 days. This MOF hybrid provides a controlled, targeted, and sustained delivery formulation for long-term pest management and crop micronutrient supply and has huge application prospects in sustainable agriculture.

“…Excessive use of pesticides and chemical fertilizers has already caused dramatic damages to the ecological environment, yet some pests and plant diseases are still not completely controlled and prevented. Thus, extensive attentions have recently been paid on biological control approaches ( Ma et al, 2021 ; Peng et al, 2021 ). Biological control approaches are highly effective to prevent plant diseases and increase the crop yields.…”

Small RNAs (sRNAs) encoded by plant genomes have received widespread attention because they can affect multiple biological processes. Different sRNAs that are synthesized in plant cells can move throughout the plants, transport to plant pathogens via extracellular vesicles (EVs), and transfer to mammals via food. Small RNAs function at the target sites through DNA methylation, RNA interference, and translational repression. In this article, we reviewed the systematic processes of sRNA biogenesis, trafficking, and the underlying mechanisms of its functions.

Controlled release and nanotechnology techniques hold promising potential for propelling the pesticide industry toward the goals of green revolution. This study introduces the concept of atom economy into the multifunctionality of controlled‐release formulations (CRFs) of pesticides from both economic and sustainable perspectives. In addition to their core function of controlling the release of active ingredient, carriers also provide additional benefits, including enhanced foliar adhesion and pesticide translocation, nutritional function, synergistic bioactivity, safety for nontarget organisms, crop stress alleviation, reduced soil leaching, soil remediation, and fluorescence visualization. These additional functions are highlighted and taken seriously. Through ingenious excogitation, the multifunctional CRFs of pesticides can achieve multiple objectives, enhancing input efficiency while minimizing environmental impacts. We tentatively blazed a trail by reviewing the recent advances in multifunctional CRFs of pesticides from the perspective of green chemistry. Additionally, potential development and implementation barriers of CRFs were discussed, emphasizing the necessity for robust field trials and comprehensive systems‐level efficacy/biosafety evaluations to substantially boost the technical readiness and performance of multifunctional CRFs of pesticides. Our goal is to expand the multifunctional concept for pesticide formulations, thereby accelerating the development of global sustainable agrochemical products.
