Cultivos leñosos en Aragón: evaluación económica de una eventual prohibición del glifosato

Conservation agriculture systems are linked to glyphosate as the main herbicide in tree crops. The recent debate on possible negative effects over human health has increased the farmers’ concern about an eventual prohibition of glyphosate in the future. The aim of this paper is to estimate the costs associated with an eventual prohibition of glyphosate in tree crops of Aragon. The costs of different alternative strategies were calculated: substitution of glyphosate in chemical control, minimum tillage, and natural or planted vegetal covers.
