Abstract
ARREGUI, M.C; GRENON, D; SANCHEZ, D and GHIONE, J. Evaluación del riesgo de impacto ambiental de plaguicidas en cultivos anuales del centro de Santa Fe. FAVE. Secc. Cienc. agrar. [online]. 2013, vol.12, n.1, pp.13-20. ISSN 1666-7719.
Assessment of pesticide environmental risks in annual crops in center of Santa Fe Pesticides are essential tools to achieve productivity and sustainability in agricultural crops when they are applied minimizing undesirable effects. Pesticide environmental impact is related to toxicity and time of exposure. Several indicators allow the calculation of this impact: GUS, IPEST and Relative Pesticide Index. Our aim was the evaluation of pesticide environmental impact on soil and water in agricultural fields of Central Santa Fe with those three indicators. All pesticide treatments applied in soybean, wheat and corn in 25 farms were recorded from 2007 and 2011, also with soil properties and pesticide characteristics. Indicators were calculated and the results were compared. Corn has the highest risk of pesticide contamination in soil and water, related to the frequent use of atrazine. Wheat and soybean had less environmental impact. The application of indicators may be helpful for considering the use of new active ingredients and their relationship with sustainable systems.
