摘要： 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. Also disclosed is a method for selectively controlling a population of target rodent pests.

摘要： A rodenticidal bait composition includes bromadiolone mainly in the form of the homostereoisomer of formula 3-[3-(4′-bromo-[1,1′-biphenyl]-4-yl)-3-hydroxy-1-phenylpropyl]-4-hydroxy-2H-1-benzopyran-2-one, where carbons 1 and 3 of the 3-hydroxy-1-phenylpropyl group have the same absolute configuration. A method for controlling rodent pests using the rodenticidal bait is also described.

摘要： Disclosed is to a composition including difethialone, containing a configurational stereoisomer of difethialone, referred to as a hetero-stereoisomer, of formula 3-(4′-bromobiphenyl-4-yl)-1-(4-hydroxythiocoumarin-3-yl)-1,2,3,4-tetrahydronaphthalene, in which the carbon atoms 1 and 3 of the 1,2,3,4-tetrahydronaphthalene group have different absolute configurations, the composition including an amount of a dextrorotatory enantiomer of the hetero-stereoisomer such that the ratio of this amount to the amount of difethialone in the composition is less than 10%; the amount of the dextrorotatory enantiomer of the hetero-stereoisomer of difethialone in the composition being different from the amount of levorotatory enantiomer of the hetero-stereoisomer of difethialone in the composition.
