“…In 518 samples from 20 diferent types of vegetables used in this investigation, a total of 32 pesticide residues were found, and the MRLs were exceeded by 7.7% of the observed pesticide residues [116]. For leafy, melon and fruit, and root vegetables, the percentages of residues that exceeded the MRLs were 11.2%, 5.1%, and 1.6%, respectively, and the percentage of samples that exceeded the MRLs for various vegetables did not vary by season [117].…”

In Ethiopia, using pesticides to manage pests in the growing of fruits and vegetables is a standard practice. Various classes of pesticides have been approved to combat pests, but the majority of those in use now are outdated broad-spectrum insecticides with significant residual effects on crops of freshly eaten fruits and vegetables. This review reveals that Ethiopia’s assessment of the residual pesticide level in fruits and vegetables has been lacking. According to the reviewed literature, crops that are often treated with pesticides in many countries have significant residual pesticide levels. However, Ethiopia has not adequately reported on this issue. Furthermore, due to a lack of knowledge regarding the impact of pesticide residues on human health, Ethiopians frequently use pesticides improperly to control pests in fruits and vegetables. The majority of consumers eat their fruits and vegetables unprocessed, without washing or cooking them first. To reduce the risk of pesticide residues in fruits and vegetables for consumer safety and to battle the health effects of toxic chemicals in humans, monitoring pesticide residues and raising awareness about the adverse effects of pesticides on humans are urgently needed. Before they may be registered and sold, pesticide residues in fruits and vegetables as well as in the environment must also undergo proper testing and evaluation. New pesticide generations that have fewer side effects on fruits and vegetables must also be developed. By washing, peeling, canning, or boiling fruits and vegetables before consumption, the detrimental effects of pesticide residues on human health can be minimized.

“…Machine Learning and Predictive Analytics: can predict outbreaks based on various factors such as weather patterns, past infestations, and cropping patterns, enabling preemptive measures [59]. Automated Pesticide Application: can ensure that pesticides are applied in the right amounts and only when necessary, reducing costs, environmental impact, and resistance buildup [60]. Beyond the traditional biological controls, new frontiers are being explored, driven by a deeper understanding of ecology and biotechnology.…”

Whitefly (Bemisia tabaci Gennadius) poses significant agricultural challenges due to its role as a vector for plant viral diseases, particularly the Chilli leaf curl disease (ChiLCD). This review discusses the multifaceted management strategies and elaborates on the future prospects and research directions to combat these threats. Precision agriculture is identified as a pivotal tool, with the utilization of drones, machine learning, and automated pesticide application offering early pest detection and targeted interventions. Exploration of novel biological controls, including RNA interference and microbiome manipulation, provide innovative avenues for sustainable pest management. A notable concern remains the development of resistance in pests. Genomic studies and an in-depth understanding of biochemical pathways have shed light on potential strategies to address resistance build-up mechanisms. Behavioral studies elucidate the adaptive changes in pests in response to pesticides. Effective management is not solely reliant on technological and biological advancements. Strengthening the linkages between farmers, extension services, and researchers is essential for the dissemination and practical application of research findings. Digital platforms, participatory research, and feedback mechanisms have emerged as beneficial in this context. While significant challenges persist in the management of Bemisia tabaci and ChiLCD, integrated approaches that combine advanced technology, innovative research, and robust stakeholder partnerships offer a promising pathway forward. This synthesis underscores the importance of interdisciplinary collaborations and continuous research in shaping sustainable agricultural practices.

“…Farajzadeh et al [ 27 ] developed a new, simple and efficient method based on evaporation of the sedimented organic phase obtained from DLLME for the analysis of multiclass pesticide residues from some fruit juice samples. Ju et al [ 28 ] applied deep eutectic solvent as the extractant, and the developed DLLME method displayed satisfactory extraction efficiency for the three neonicotinoid pesticides in edible oils, and coupled this with HPLC for the detection. However, this technology is only suitable for several compounds or a class of compounds, and the sample matrix is relatively limited and cannot meet the requirements of high throughput and automatic pretreatment.…”

Sample pretreatment is a vital step in the detection of mycotoxins, and traditional pretreatment methods are time-consuming, labor-intensive and generate much organic waste liquid. In this work, an automatic, high-throughput and environmentally friendly pretreatment method is proposed. Immunomagnetic beads technology and dispersive liquid–liquid microextraction technology are combined, and the zearalenone in corn oils is directly purified and concentrated under the solubilization effects of surfactant. The proposed pretreatment method allows for the batch pretreatment of samples without pre-extraction using organic reagents, and almost no organic waste liquid is produced. Coupled with UPLC-FLD, an effective and accurate quantitative detection method for zearalenone is established. The recovery of spiked zearalenone in corn oils at different concentrations ranges from 85.7 to 89.0%, and the relative standard deviation is below 2.9%. The proposed pretreatment method overcomes the shortcomings of traditional pretreatment methods and has broad application prospects.
