Abstract

Anticoagulant rodenticides were studied under shelf storage con­ditions using chemical and biological assessment. The obtained results showed that storage periods significantly affected on bait acceptance, efficiency and stability of the tested anticoagulants and the effect dif­fered according to bait type, chemical structure of the anticoagulant and period of storage . The attractiveness of Final and "T.R.C" compounds to the albino rats, Rattus contagious, was less than storm. Regarding the efficiency of the three tested compounds to albino rat, it was clear that the three anticoagulants completely killed tested animals during all periods of storage, while average consumed bait (gr/ kg b.w) and active ingredient (mg /kg b.w.) increased with the prolonga­tion of the storage period. On the other hand, the chemical assay of the three anticoagu­lants during the different periods of storage revealed that their active in­gredient slightly decreased with the increasing of storage periods.
