Riesgo ambiental por el uso de fitosanitarios en cultivos anuales de la cuenca del arroyo Ludueña, Santa Fe

Abstract

The objective of this work was to evaluate the environmental risk caused by the application of pesticides products in annual crops in a rural basin in the south of Santa Fe. In four landscape units six types of annual agricultural uses were selected. In each combination the environmental risk was evaluated by the application of pesticides products through an index of integration. The pesticides management guidelines related to the type of active principle, dosage and application technology were determined. The index considered weather, soil and application site information. Landscape units with better natural conditions have low risk due to the use of pesticides products for all sequences of annual crops. Regarding the indicators that make up the index, the presence of the active ingredient was the highest in all landscape units, with air being the lowest risk in general. The one of superficial water was low for the six uses in the best landscape units and high in those of worse natural characteristics, the one of underground water did not show a clear association between types of uses and units of landscape. The index of integration used was useful to discriminate the environmental risks derived from the application of pesticides products in annual agricultural crops in different sectors of the basin.
