Synergistic and residual pesticidal compositions containing plant essential oils with enzyme inhibitors
Synergistic and residual pesticidal compositions containing synergistic and residual mixtures of plant essential oils in admixture with enzyme inhibitors, with or without other compounds not previously used as active ingredients in pesticidal formulations. In addition, the present invention is directed to a method for controlling pests by applying a pesticidally-effective amount of the above synergistic and residual pesticidal compositions to a locus where pest control is desired.
1 .- 17 . (canceled)
18 . A pesticidal composition comprising:
an inert carrier and a pesticidally-effective active ingredient, wherein the active ingredient consists of piperonyl butoxide and at least one plant essential oil compound selected from the group consisting of thyme oil and thymol,
with the proviso that no other pesticidally active ingredient is present.
19 . The pesticidal composition of claim 18 , wherein the plant essential oil compound is thyme oil.
20 . The pesticidal composition of claim 18 wherein the plant essential oil compound is thymol.
21 . The pesticidal composition of claim 18 , wherein the piperonyl butoxide and plant essential oil compound are present in a ratio of about 1:2 parts by weight.
22 . A method for killing or controlling a pest, comprising:
applying a pesticidally effective amount of the composition of claim 18 to a locus where killing or control of pests is desired.
23 . The method of claim 22 , wherein the pest is a cockroach.
