“…In the case of corn crops, the incidence of pest infestations from germination to harvest, can compromise grain yield and quality, causing crop damage, with significant economic loss. The use of insecticides seed treatment is an alternative for minimizing the action of pests and preventing productivity losses, which is translated into an economic return (Grande & Rando, 2018). (Sapbamrera & Thammachaia, 2020).…”

Unsafe management practices and overuse of pesticides have led to environmental contamination and farmworkers poisoning. For this reason, the problem of pesticide exposure must be framed in the socio-cultural and environmental context of the affected communities, analyzing the factors that contribute to the greater risk of exposure of farmworkers and their families, in order to propose educational strategies and develop effective public health strategies. This study evaluated the knowledge, attitudes, and practices regarding local pesticides handling of farmworkers from Singuil town, Catamarca province, northwestern Argentina, and the possible impact of these behavioral patterns on Singuil River. Farmworkers from Singuil town participated through a cross-sectional, face-to-face survey. Subsequently, samples from Singuil River were taken for determination of pesticides residues. Approximately 83 % of those surveyed have worked with pesticides for more than 10 years. Although most workers prepare their pesticide formulations, 25 % of them never use any personal protective equipment, while the remaining 75 % usually use face masks and gloves to protect themselves. Post-spraying personal hygiene practices, such as changing clothes or showering, are often not applied. To reduce health risks, many respondents perform sprinkling at sunset (66.7 %) or early morning (50 %), and avoid it during windy and sunny weather. Besides, they usually burn (58.3 %) or stockpile (41.7 %) empty pesticide containers. In case of poisoning, 91.7 % of workers would go to hospital for medical attention. Glyphosate, mancozeb, and propamocarb are the most commonly used pesticides. Finally, no pesticide residues were detected in the water samples collected from Singuil River.

The present study aimed to evaluate insecticide toxicity to Doru luteipes (Scudder), a major predator of corn pests. Lethal (reduction in survival) and sublethal effects (prey consumption, adult tibia length and walking distance) of compounds were assessed on earwig nymphs and adults. Insects were exposed to the compounds through contact (exposure to insecticide residue on corn leaves) and ingestion (consumption of insecticide-treated prey) routes. Tested insecticides included a biopesticide (Spodoptera frugiperda multiple nucleopolyhedrovirus -SfMNPV), and modern ( ubendiamide and meta umizone) and older neurotoxins (imidacloprid + β-cy uthrin). The imidacloprid/β-cy uthrin mix was highly toxic (100% mortality) to the predator, regardless of the exposure route and predator stage. Meta umizone caused mortality superior to 95% and 45% of nymphs and adults, respectively. Flubendiamide and SfMNPV were the least toxic compounds, not differing from the untreated control in any of the assessed endpoints. Adult tibial length did not differ among treatments. Overall, the insecticides caused a more pronounced effect on D. luteipes nymphs than on adults and were more toxic by the contact route. From these ndings, ubendiamide and SfMNPV are safer for D. luteipes and should head insecticide choice in integrated pest management programs in corn.
