Pesticide use is increasing in low- and middle-income countries (LMICs) including Costa Rica. This increase poses health risks to farm owners, workers, communities living near agricultural farms.We aimed examine the effects associated with occupational pesticide exposure owners workers from conventional organic smallholder farms Rica.We conducted a cross-sectional study involving 300 horticultural Zarcero County, During baseline visit, we administered structured, tablet-based questionnaire...
Abstract We here report of a conference about “Pesticides in Soil, Groundwater and Food Latin America as part One Health” that took place at the “IV Seminario Internacional de Sanidad Agropecuaria (SISA)” Varadero, Cuba, 8–12 May 2023. Researchers (Argentina, Brazil, Chile, Costa Rica, Colombia, Mexico) Switzerland (workshop initiator) held presentations occurrence effects pesticides on environment, human health, replacement highly hazardous (HHP) by agroecological alternatives agri-food...
El objetivo del presente trabajo fue realizar un diagnóstico de uso plaguicidas y otros agroquímicos, a los productores papa en Cartago, Costa Rica. Se emplearon cuestionarios campo entre años 2006 2009 la microcuenca las quebradas Plantón Pacayas. Cada productor como promedio utilizó 32,8 kilogramos ingrediente activo (i.a.) plaguicida por hectárea ciclo, rango 10,9 88,3. Como ponderado se calculó valor 42,6 kg i.a./ha/ciclo para 1879 fertilizante formulado/ciclo. grupo mayor lo...
Costa Rica es uno de los mayores importadores y usuarios plaguicidas a nivel centroamericano. El glifosato el herbicida mayor uso, tanto en mundo como Rica. Se utiliza la mayoría cultivos: anuales, perennes zonas no agrícolas. Por medio entrevistas sujetos productores agrícolas se conocieron las cantidades usadas principales cultivos. Las importaciones este iniciaron 1982 con 36 toneladas ingrediente activo (T i.a.), llegó importar 1 761 T i.a. 2013. calculó uso ponderado kg i.a./ha/ciclo....
Agricultural pesticides imported in Central America were analyzed, for period the 2005-2009 order to monitor health hazards. The methodology used has already been published analysis of 2000-2004 (Bravo et al., 2011). During 2005-2009, 353 active ingredients (ai) an average annual amount 39 000 ton ai. Fourteen ai quantities ≥ 2000 accounted 77% imports. biocidal actions most fungicides and herbicides. In these actions, chemical groups dithiocarbamates phenoxyacid fosfonoglicinas bipyridyls...
Abstract A small proportion of the thousands pesticides on market today are associated with a disproportionately high incidence severe acute pesticide poisoning and suicide. Paraquat stands out as one most lethal in common use, frequently involved fatal incidents due to suicides or accidental exposure. Even though paraquat has been banned over 67 countries, it is still widely used many others. Based literature review consultation process, this paper identifies options for replacing distils...

Durante los años 2012 y 2013 se estudió, en un invernadero Tambor de Alajuela, la respuesta biotipos Paspalumpaniculatum, una maleza poacea, al herbicida glifosato, con el objetivo determinar su nivel resistencia. Los zacate cabezón provenían fincas productoras palmito pejibaye, banano orgánico convencional provincia Limón, bordes caminos Guanacaste Heredia. A las plantas les aplicaron dosis crecientes glifosato midió peso fresco 21 días después. Se encontraron tres resistentes a (R), que...
