A new concept of economic injury level that includes penalization of damage to quality and safety of agricultural productsDiscussion
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.
