“…We applied the open-storage scenario to simulate the ratios of pesticide concentrations in the peel and medulla, which were compared with existing studies that measured concentrations after purchasing potatoes from markets. In addition to the organochlorine pesticides provided by Soliman, we also evaluated the model’s performance by comparing the simulated half-lives of pesticides in postharvest potatoes with reported values for current-use pesticides (e.g., the neonicotinoids, diarylamines, and pyrethroids). − …”

“…To further evaluate the performance of the proposed model, we compared the parametrized t 1/2,M P values (see eq 14) as well as the simulated t 1/2,M NP values (see eq 10) with field measurements (half-life, t 1/2 F ) for some pesticides that are currently used in potato fields. For example, imidacloprid, a systemic insecticide belonging to the neonicotinoids, is widely applied to control insects in agricultural fields, 38 and its residues are frequently detected in vegetables and tuber crops, 44 which can lead to a threat to food safety and public health. Yu et al measured the dissipation rate of imidacloprid in sweet potatoes, which yielded a t 1/2 F value of 3.2−5.5 days in postharvest sweet potatoes.…”

To evaluate pesticide distribution and dissipation patterns in postharvest tubers, a peel model under open-environment conditions was developed, which could specify the fate of pesticides in the peel and medulla (pulp) compartments. The simulated results for over 700 pesticides in potatoes indicated that the pesticide degradability in crop tissues contributed the most to the overall dissipation in the medulla compartment than other physiochemical properties. The dissipation process in potato medullas was diminished by the peel compartment, indicating that the peel acts as a protective layer, particularly for highly lipophilic pesticides with high peel-to-medulla concentration ratios at harvest. In addition, the simulated results showed that the peel-to-medulla pesticide concentration ratios decreased significantly immediately after potatoes were harvested (e.g., 1 or 3 days after harvest), which was consistent with the field observations, indicating that pesticide distribution in the peel and medulla compartments achieved steady state if the source of the pesticide was blocked (i.e., pesticide residues in soil). Furthermore, the simulated reduction factors of pesticides in potato medullas were parametrized using the nonpeel model, which helped derive the equivalent half-lives of pesticides in potato medullas after accounting for the peel effect. It was concluded that the tuber peel can act as a protective layer to reduce residue dissipation in medulla tissues, and the dissipation half-lives of pesticides in cold storage (e.g., 5 °C) can be over two times longer than those at room temperature. The present study provides a modeling perspective on pesticide dissipation kinetics in postharvest tuber crops, and the simulated results can be combined with other food processing factors to evaluate the fate of pesticide residues in the tuber food supply chain.

“…Many studies across the globe have attempted to reduce its impact on sustainable agricultural productivity [24][25][26]. Whitefly management (WFM) strategies can be grouped as traditional [27,28] , chemical [29,30] , herbal [31,32], biological [33,34], biotechnological [35,36], and IPM [37,38]. However, a robust, reliable, and cost-effective WFM strategy is still needed [39,40].…”

Whitefly (Bemisia tabaci) Management (WFM) Strategies for Sustainable Agriculture: A Review

et al. 2022

The whitefly (Bemisia tabaci Gennadius) is a notorious devastating sap-sucking insect pest that causes substantial crop damage and yield losses due to direct feeding by both nymphs and adults and also through transmission of viruses and diseases. Although the foliar application of synthetic pesticides is crucial for efficient control of B. tabaci, it has adverse effects such as environmental pollution, resistance and resurgence of the pest, toxicity to pollinators, and crop yield penalty. Thus, a suitable, safe, and robust strategy for the control of whiteflies in the agricultural field is needed. The reports on whitefly-resistant transgenic plants are scanty, non-reproducible, and/or need secondary trials and clearance from the Genetic Engineering Appraisal Committee (GEAC), the Ministry of Environment and Forests (MoEF), and the Environmental Protection Agency (EPA). The present review encompasses explicit information compiled from 364 articles on the traditional, mechanical, biological, biotechnological, and chemical strategies for whitefly management (WFM), IPM strategy, and future prospects of WFM for food and agriculture security.
