Abstract: The traditional model of Economic Injury Level (EIL) does not allow to directly incorporate aspects of damage to quality and safety of a product (Dq) into the decision-making process to control a pest (pathogen, weed, arthropod, vertebrate). This work now attempts to generalize a concept of EIL by (i) separating damages to quality and safety (i.e. Dq and EILq) from quantitative (i.e. Dw and EILw) types of damage (D) in the traditional EIL-equation, and (ii) by establishing a new way of estimation of EILq based on the penalization of quality and/or safety damage. The importance to distinguish between the terms EIL, EILw and EILq is discussed, and a calculation of the new index (Z), enabling the comparison of the relative economic importance of qualitative and quantitative damage caused by a particular level of pest infestation or disease severity, is proposed.
