“…The spiked recoveries of the water samples ranged from 91.1% to 108%, 114% to 118%, and 92.5% to 97.4%, respectively, and the relative standard deviations were all less than 6%. This shows that the molecularly imprinted sensor can meet the requirements of rapid detection of cyromazine in tomato and cowpea and water samples [ 22 ].…”

Cyromazine is an insect growth regulator insecticide with high selectivity and is widely used in the production and cultivation of fruits and vegetables. In recent years, incidents of excessive cyromazine residues in food have occurred frequently, and it is urgent to establish an accurate, fast, and convenient method for the detection of cyromazine residues to ensure the safety of edible agricultural products. To achieve rapid detection of cyromazine residues, we prepared a molecularly imprinted electrochemical sensor for the detection of cyromazine residues in agricultural products. Samples of tomato (Lycopersicon esculentum Miller), cowpea (Vigna unguiculata), and water were tested for the recovery rate of cyromazine. The results showed that the concentration of cyromazine showed a good linear relationship with the peak response current of the sensor developed in this study. The lower limit of detection for cyromazine was 0.5 µmol/L, and the sensor also had good reproducibility and interference resistance. This paper can be used as a basis for the study of methods for the detection of cyromazine residues in edible agricultural products.

“…However, in Mexico the application of pesticides is excessive, even are applied some products that are prohibited or not allowed in other countries. For example, according to the Food and Agriculture Organization of the United Nations (FAO), during 2013-2017 the average use of pesticides was estimates in 2 kg/ha (Calderon et al, 2022), peaking in 2014 at 3.85 kg ha 1 (López-Gálvez, Wagoner, Beamer, de Zapien, & Rosales, 2018). Besides, although Mexico participates in different international agreements dealing with pesticides, continues to be using pesticides prohibited in other countries such as paraquat, endosulfan, lindane, methyl bromide, parathion, and malathion (Anket Sharma et al, 2019).…”

Objective: To perform a literature review of the presence of pesticides in edible insects, main pesticides used in Mexico and to discuss the potential risk of contaminated edible insects for human consumption. Design/methodology/approach: Concise analysis of the main research topics related with the impact of pesticides on insects, through a wide review of specialized journals on insects’ field. Results: The majority of edible insects are considered as a common plague in some crop varieties, causing a decrease in their production yield. As a result, farmers use mainly chemical insecticides to control this plague. Besides, farmers use also chemical herbicides and fungicides to control weeds and fungi. However, those pesticides have a negative impact on edible insects because they can be contaminated. These contaminated edible insects can be collected from different crop varieties for their use as food. Limitations on study/implications: To conduct further research to identify and determine the pesticide levels in edible insects consumed in Mexico. Findings/conclusions: Edible insects may represent a potential risk to human health, especially when insects are wild harvested because can be contaminated with pesticides, particularly insecticides, herbicides, and fungicides.

“…The production of vegetables in Chile is characterized by improper and excessive use of pesticides resulting in environmental pollution and human health risk (Elgueta et al, 2020;Calderon et al, 2022). Elgueta (2020) found that tomatoes and lettuce produced in the Metropolitan Region contained residue levels considerably exceeding maxima allowed in Chile.…”

“…The majority of the farmers in developing and emerging economies operate with intermediaries or wholesalers rather than with lead firms (Guarín, 2013;Mariyono et al, 2020), and only a limited number of farmers use SAPs (Elgueta et al, 2020;Calderon et al, 2022). There is a lack of knowledge on the relationships of farmers with other buyers and SAP adoption.…”

A value chain perspective towards sustainable agricultural practices: the case of vegetables in Chile

Vegetable production is highly dependent on chemical fertilisers and pesticides, but the intensive use of these inputs negatively impacts the environment and human health. Ecological Intensification (EI) has the potential to counter the adverse effects of agricultural intensification and improve sustainability. Despite the potential benefits of EI for the environment, the adoption rate of EI in vegetable production is low.Moreover, most studies on EI adoption focus on implementing a single farming practice or a single production stage. This article aims to empirically analyse what factors influence the simultaneous adoption of various EI practices in different vegetable crop production stages by farmers in the context of an emerging economy such as Chile. Further, since the literature on EI practices adoption mainly analyses these factors as separate from each other, we aim to explore the interactions between factors and how these jointly impact the application of EI practices. We collected data via a survey to vegetable growers in the central zone in Chile. First, we measure EI practices adoption through a farm-level index that reflects the sustainability of farming practices in five production stages. Second, we identify which factors affect EI practices adoption through multiple linear regressions. Third, based on the results of the previous steps, we carried out a literature review to see how the factors predicting the adoption of EI could interact. This analysis was performed using structural equation modelling. Our results show that being a woman, receiving training on EI practices, and being pro-environment are positively related to EI practices adoption. Contrarily, obstacles include the perception of risk and barriers, better access to credit and higher income from farm activities, all of which are negatively related to EI practices adoption. With reference to the interaction among the factors, we found that economic resources, trust and training are the main correlated factors to the perception of risk and barriers amongst Chilean farmers when it comes to adopting EI practices. Embracing a broad perspective, including different farming practices and production stages, allowed us to offer insights into the complex processes of adopting EI practices.Identifying which factors are important and how these factors interact with each other, contributes to the debate on what policymakers and scholars need to focus in order to increase the use rate of EI practices.
