Consequently, the development of supramolecular drug carriers based on host–guest interactions, particularly cyclodextrins, has shown promise in precision agriculture due to their predictable and adjustable properties. In this study, a series of amphiphilic random copolymers incorporating hydrophilic acrylamide and hydrophobic benzotriazole were designed and synthesized through coprecipitation to form a supramolecular inclusion complex. The copolymer and inclusion complex demonstrated pH-responsive behavior, which enabled the controlled release of benzotriazole for the targeted control of <i>B. cinerea</i>, a destructive phytopathogen that causes gray mold disease. The antimicrobial activity of the complex was observed to be superior in targeting specific SF9 cells compared to HepG2 cells and exhibited favorable biosafety.

Control strategies currently include chemical and nonchemical means, but the implementation of digital systems able to support detection of outbreaks and promote optimization of interventions may concur to increase efficacy of management strategies. Thermography, based on the recording and analysis of thermal energy emitted by plant canopy in the infrared spectral range, is a well-known imaging technique able to monitor plants at both proximal and remote scales providing information on incipient plant stresses. In this work, wild rocket plants subjected to artificial infection with pathogen conidia performed by a dipping or flooding method were monitored during the pathogenesis by both passive and active thermographic approaches. Canopy temperature changes were compared with symptom severity indices measured by visual inspection on both inoculated and control plants. As key result of this study, depending on the inoculum concentration, passive thermography allowed classifying infected plants 30–48 h post inoculation (hpi) by dipping, and in coherence with the disease symptoms detection by visual inspection. Similar results were found in the case of the flooding inoculation, where infected plants were detected by thermography at 48 h.p.i. Active thermography revealed a decrease in leaf heat capacity attributable to the fungal infection and the subsequent tissue colonization over time. These findings constitute a solid base of knowledge about the thermal imaging applied to wild rocket affected by Fusarium wilting, and they can contribute to the development of new remote sensing systems for the detection of primary outbreaks.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"4 5","pages":"544–553"},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141000747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant growth and health were assessed by measuring the soybean biomass and chlorophyll content in both healthy and <i>Fusarium</i>-infected plants at harvest.

A single seed treatment of MSNs reduced disease severity by 30% and increased chlorophyll content in both healthy and infected plants by 12%. Based on greenhouse results, seed application was used in the follow-up field study and MSNs and CTS-MSNs reduced disease progression by 12 and 15%, respectively. A significant 32% increase was observed for chlorophyll content for plants treated with CTS-MSNs. Perhaps most importantly, nanoscale silica seed treatment significantly increased (23–68%) the micronutrient (Zn, Mn, Mg, K, B) content of soybean pods, suggesting a potential sustainable strategy for nano-enabled biofortification to address nutrition insecurity.
