Abstract
Disclosed is a rodenticide bait including: difenacoum in the form of trans-difenacoum of formula 3-(biphenyl-4-yl)-1 -(4-hydroxycoumarin-3-yl)-1,2,3,4-tetrahydronaphthalene, in wherein carbons 1 and 3 of group 1,2,3,4-tetrahydronaphthalene of the trans-difenacoum have the same absolute configuration; and an edible excipient for target rodent pests. The bait includes trans-difenacoum at a concentration above a minimum trans-difenacoum concentration lethal to female adults of the target rodents, but below a minimum trans-difenacoum concentration lethal to adult males of the target rodents, the minimum concentration lethal to female adults being less than the minimum concentration lethal to male adults.
