“…The performance of smart pesticide delivery systems is critically linked to gated materials, which include two subunits: porous carriers to load drugs and gatekeepers for drug release control from the pores . Hollow mesoporous silica nanoparticles (HMSNs) are a developed pesticide carrier that has been widely used in gated system design because of their large drug loading capacity, customized mesoporous structure, biocompatibility, and capacity for drug delivery through flexible surface functionalization. − Compared to HMSNs, hollow mesoporous organosilica nanoparticles (HMONs), with enhanced biodegradability and glutathione (GSH)-responsive properties to release pesticides specifically in response to GSH in insects, have been used as nanocarriers to control Panonychus citri (McGregor) but have rarely been selected as nanocarriers to control plant diseases until now.…”

An intelligent delivery nanoformulation could enhance the utilization efficacy, uptake, and translocation of pesticides in plants. Herein, a redox/pH-triggered and fluorescent smart delivery nanoformulation was designed and constructed by using hollow mesoporous organosilica nanoparticles (HMONs) and ZnO quantum dots as the nanocarrier and capping agent, respectively. Boscalid was further loaded to generate Boscalid@ HMONs@ZnO with a loading rate of 9.8% for controlling Botrytis cinerea (B. cinerea). The quantity of boscalid released by Boscalid@ HMONs@ZnO in a glutathione environment or at pH 3.0 was 1.3fold and 1.9-fold higher than that in a neutral condition. Boscalid@ HMONs@ZnO has 1.7-fold the toxicity index of boscalid technical against B. cinerea in antifungal experiments. Pot experiments revealed that the efficacy of Boscalid@HMONs@ZnO was significantly enhanced more than 1.27-fold compared to commercially available water-dispersible granules of boscalid. Due to the fluorescence properties of Boscalid@HMONs@ZnO, pesticide transport's real-time monitoring of pesticide translocation in tomato plants could be observed by confocal laser scanning microscopy. Fluorescence images revealed that HMONs@ZnO had been effectively transported via treated leaves or roots in tomato plants. This research showed the successful application of HMONs@ZnO as a nanocarrier for controlling disease and offered an effective avenue to explore the real-time tracking of pesticide translocation in plants.

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.
