Pesticides, a love story : America's enduring embrace of dangerous chemicals
\"A provocative cultural history of pesticides and their controversial use and depiction in the United States. Mart contends that--despite the sharp concerns raised by environmentalists and others since the appearance of Rachel Carson's Silent Spring--Americans have not only never resolved the inherent tension between costs and benefits presented by these chemicals, but have actually grown ever more attached to them with the passage of time\"-- Provided by publisher.

Food Systems in an Unequal World
Pesticides, a short-term aid for farmers, can often be harmful, undermining the long-term health of agriculture, ecosystems, and people. The United States and other industrialized countries import food from Costa Rica and other regions. To safeguard the public health, importers now regulate the level and types of pesticides used in the exporters' food production, which creates \"regulatory risk\" for the export farmers. Although farmers respond to export regulations by trying to avoid illegal pesticide residues, the food produced for their domestic market lacks similar regulation, creating a double standard of pesticide use.Food Systems in an Unequal Worldexamines the agrochemical-dependent agriculture of Costa Rica and how its uneven regulation in export versus domestic markets affects Costa Rican vegetable farmers. Examining pesticide-dependent vegetable production within two food systems, the author shows that pesticide use is shaped by three main forces: agrarian capitalism, the governance of food systems throughout the commodity chain, and ecological dynamics driving local food production. Those processes produce unequal outcomes that disadvantage less powerful producers who have more limited choices than larger farmers, who usually have access to better growing environments and thereby can reduce pesticide use and production costs.
Despite the rise of alternative food networks, Galt says, persistent problems remain in the conventional food system, including widespread and intensive pesticide use. Facing domestic price squeezes, vegetable farmers in Costa Rica are more likely to supply the national market with produce containing residues of highly toxic pesticides, while using less toxic pesticides on exported vegetables. In seeking solutions, Galt argues for improved governance and research into alternative pest control but emphasizes that the process must be rooted in farmers' economic well-being.

Economic Impact of Chemical Pesticide Ban on Mealybug Management in Commercial Banana Farms in Cameroon Highlights the Need for Policy Initiatives on Sustainable Alternatives
Banana ( Musa spp.) production is source of food, income and foreign exchange, but banana mealybug ( Pseudococcus elisae ) infestation is a major production constraint that was only highlighted in 2007 following rejection of banana from Cameroon Development Cooperation (CDC) in international markets. Increased banana rejection with the ban on chlorpyrifos insecticide‐treated bags in 2019, requires insights on the current status of banana rejection and relevant policies. In order to advance evidence‐based debates on policy implications of chlorpyrifos ban on banana trade, we explored secondary data from CDC at prechlorpyrifos ban (PreCB; 2014–2016) and postchlorpyrifos ban (PostCB; 2020–2022). Thereby, providing situational insights on impacts of mealybug infestation at CDC farms on market rejection of banana and financial losses in PreCB and PostCB. This will facilitate relevant policy formulations that can enable adaptation to current and future shocks on pesticide use and banana trade. Findings revealed no banana rejection due to mealybug infestation in at least 2 months of PreCB years, whereas banana was rejected in all 12 months of PostCB years. Rejection of banana bunches due to mealybug infestation increased by 6–folds in PostCB with the highest in February 2021 and January 2022. Monthly financial loss resulting from mealybug infestation differed significantly ( p < 0.029) between PreCB (∼US $3100) and PostCB (∼US$ 7600). Besides market rejection of banana and economic losses due to mealybug infestation, business rating and reputation of CDC are downgraded, highlighting the urgent need for policy initiatives to reduce dependence on chemical pesticides, and promote sustainable alternative management options.

Dissipation Kinetics and Risk Assessment of Diniconazole, Dinotefuran, Metconazole, and Tebuconazole in IRaphanus sativus/I L
This study investigated the degradation characteristics and conducted a risk assessment of four pesticides (Diniconazole, Dinotefuran, Metconazole, and Tebuconazole) in the leaves and roots of radish. Radish was cultivated in two greenhouse fields, and samples were collected at 0, 1, 2, 3, 5, 7, and 10 days after pesticide application. Sample analysis was performed using LC-MS/MS, and the recovery rates ranged from 70.1% to 118.6%. The biological half-life of Diniconazole was found to be 6.2 days (leaf and root), Dinotefuran was 5.3 days (leaf) and 4.6 days (root), Metconazole was 9.3 days (leaf) and 3.2 days (root), and Tebuconazole was 8.0 days (leaf) and 5.1 days (root). After comparing the maximum residue limits (MRL) of each pesticide in Korea with the residues during the pre-harvest interval (PHI), Diniconazole showed a Hazard quotient (HQ) exceeding 1, indicating potential risks for true consumers. Furthermore, Tebuconazole showed an HQ of 0.3 or higher, indicating a significant level of risk.

Microbial pesticides – challenges and future perspectives for testing and safety assessment with respect to human health
Plant protection measures are necessary to prevent pests and diseases from attacking and destroying crop plants and to meet consumer demands for agricultural produce. In the last decades the use of chemical pesticides has largely increased. Farmers are looking for alternatives. Biopesticides should be considered a sustainable solution. They may be less toxic than chemical pesticides, be very specific to the target pest, decompose quickly, and be less likely to cause resistance. On the other hand, lower efficacy and higher costs are two disadvantages of many biopesticides. Biopesticides include macroorganisms, natural compounds and microorganisms. Microbial pesticides are the most widely used and studied class of biopesticides. The greatest difference between microbial and chemical pesticides is the ability of the former to potentially multiply in the environment and on the crop plant after application. The data requirements for the European Union and the United States Environmental Protection Agency are highlighted, as these regulatory processes are the most followed in regions where local regulations for biopesticide products are not available or vague. New Approach Methods already proposed or harmonized for chemical pesticides are presented and discussed with respect to their use in evaluating microbial pesticide formulations. Evaluating the microbials themselves is not as simple as using the same validated New Approach Methods as for synthetic pesticides. Therefore, the authors suggest considering New Approach Method strategies specifically for microbials and global harmonization with acceptability with the advancements of such approaches. Further discussion is needed and greatly appreciated by the experts.

Pesticide Use and Degradation Strategies: Food Safety, Challenges and Perspectives
While recognizing the gaps in pesticide regulations that impact consumer safety, public health concerns associated with pesticide contamination of foods are pointed out. The strategies and research directions proposed to prevent and/or reduce pesticide adverse effects on human health and the environment are discussed. Special attention is paid to organophosphate pesticides, as widely applied insecticides in agriculture, veterinary practices, and urban areas. Biotic and abiotic strategies for organophosphate pesticide degradation are discussed from a food safety perspective, indicating associated challenges and potential for further improvements. As food systems are endangered globally by unprecedented challenges, there is an urgent need to globally harmonize pesticide regulations and improve methodologies in the area of food safety to protect human health.

Pesticides and environmental injustice in the USA: root causes, current regulatory reinforcement and a path forward
Many environmental pollutants are known to have disproportionate effects on Black, Indigenous and People of Color (BIPOC) as well as communities of low-income and wealth. The reasons for these disproportionate effects are complex and involve hundreds of years of systematic oppression kept in place through structural racism and classism in the USA. Here we analyze the available literature and existing datasets to determine the extent to which disparities in exposure and harm exist for one of the most widespread pollutants in the world – pesticides. Our objective was to identify and discuss not only the historical injustices that have led to these disparities, but also the current laws, policies and regulatory practices that perpetuate them to this day with the ultimate goal of proposing achievable solutions. Disparities in exposures and harms from pesticides are widespread, impacting BIPOC and low-income communities in both rural and urban settings and occurring throughout the entire lifecycle of the pesticide from production to end-use. These disparities are being perpetuated by current laws and regulations through 1) a pesticide safety double standard, 2) inadequate worker protections, and 3) export of dangerous pesticides to developing countries. Racial, ethnic and income disparities are also maintained through policies and regulatory practices that 4) fail to implement environmental justice Executive Orders, 5) fail to account for unintended pesticide use or provide adequate training and support, 6) fail to effectively monitor and follow-up with vulnerable communities post-approval, and 7) fail to implement essential protections for children. Here we’ve identified federal laws, regulations, policies, and practices that allow for disparities in pesticide exposure and harm to remain entrenched in everyday life for environmental justice communities. This is not simply a pesticides issue, but a broader public health and civil rights issue. The true fix is to shift the USA to a more just system based on the Precautionary Principle to prevent harmful pollution exposure to everyone, regardless of skin tone or income. However, there are actions that can be taken within our existing framework in the short term to make our unjust regulatory system work better for everyone.

Special Collection: World-Scale Ecology and Management of Fall Armyworm
Insecticides and genetically modified Bt crops are the main tools for control of the fall armyworm, Spodoptera frugiperda (J.E. Smith). Since its invasion of Africa, the Far East, and Australia where Bt crops are largely absent, insecticide use has increased and reduced susceptibility to several insecticides used for decades in its native distribution area have been reported. Poor efficacy at field-level is sometimes incorrectly ascribed to pest resistance, while numerous other factors influence efficacy at field-level. In this paper, we review the history of insecticide resistance in S. frugiperda and discuss the influence that life history traits, migration ecology, and chemical control practices may have on control efficacy and resistance evolution. The indirect role that poor national policies have on pesticide use practices, and indirectly on control efficacy and selection pressure is discussed. Evidence shows that local selection for resistance drives resistance evolution. Integrated pest management, rather than reliance on a single tactic, is the best way to suppress S. frugiperda numbers and the over-use of insecticides which selects for resistance. Key words: invasive pest, insecticide resistance management, pest management

Assessment of pesticide use and pesticide residues in vegetables from two provinces in Central Vietnam
Pesticide residue in food, especially in vegetables, is one of the important parameters to assess food safety. This study evaluates the pesticide use in vegetables from two provinces in Central Vietnamand and present data on pesticides detected in vegetables sampled from the sites. The potential health risk associated with the contamination of four commonly used pesticides in different vegetables is also discussed. Both household surveys and monitoring campaigns were conducted. The survey showed that improper pesticide application, storage, and waste disposal prevailed at the study sites. Only 20% of the respondent were aware of pesticide toxicity. As a result, pesticides were detected in 81% out of 290 vegetable samples collected at harvesting time. Up to 23% of samples had pesticide residues above the Maximum Residue Limit values. The highest total pesticide concentration quantified in vegetables in Thua Thien Hue was 11.9 mg/kg (green onions), and in Quang Binh was 38.6 mg/kg (mustard greens). Median residue levels of individual pesticides in vegetables ranged from 0.007 to 0.037 mg/kg. Among the ten target pesticides, cypermethrin, difenoconazole, and fenobucarb were detected at the highest frequencies (72%, 41%, and 37%, respectively). Pesticide residues varied between seasons at both study provinces. Pesticide contamination in the wet season was significantly higher than in the dry season. This study also discovered a potential health risk associated with fipronil residues in vegetables in Thua Thien Hue province. The paper provides recommendations for mitigation measures (both technological and social) in reducing potential health risks linked to pesticide use in vegetables in the region.
