Pesticidal formulations.

Abstract

This invention relates to an animal pour-on pesticidal formulation which comprises at least one pesticide selected from the group consisting of the synthetic pyrethroids, preferably cypermethrin, the organophosphates and the amidines, and at least one vegetable oil consisting of glycerides of carboxylic acids with carbon chain lengths of more than 14 carbon atoms e.g. sunflower oil, as carrier for the pesticide which carrier constitutes at least 70% m/v of the formulation. The formulation may optionally further include a synergist, preferably piperonylbutoxide and solvents such as diacetone alcohol and dibutylphthalate.

12 claims: 4 independent, 8 dependent

  1. 1
    An animal pour-on pesticidal formulation which comprises at least one pesticide selected from the group consisting of the synthetic pyrethroids, the organophosphates and the amidines, and at least one vegetable oil consisting of glycerides of carboxylic acids with carbon chain lengths of more than 14 carbon atoms as carrier for the pesticide which carrier constitutes at least 70% m/v of the formulation.
  2. 7
    The pesticial formulation of cliam 5 wherein the synthetic pyrethroid is cypermethrin enriched as to the (1R cis)S and (1S cisR) enantiomer isomer pair of alpha-cyano-3-phenoxybenzyl-3-(2,2-­dichlorovinyl)-2,2-dimethyl cyclopropane carboxylate.
  3. 10
    The pesticidal formulation of any one of claims 5 to 9 wherein the solvent is a mixture of dibutylphthalate and diacetonealcohol which are both present in the formulation in an m/v percentage of between 0,1 and 10%.
  4. 12
    A method of combatting ectoparasite infestation on an animal host comprising the steps of applying to a localised region of the host an ectoparasiti­cidally effective amount of formulation of any one of claims 1 to 11.
