Synergistic and residual pesticidal compositions containing plant essential oils with enzyme inhibitors

Abstract

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.

23 . A method for killing or controlling a pest, comprising:
 applying to a locus where killing or control of pests is desired a pesticidally-effective amount of a composition comprising:   
       pesticidally-acceptable carrier and a pesticidally-effective active ingredient, wherein the pesticidally-active ingredient comprises piperonyl butoxide and at least one plant essential oil compound selected from the group consisting of cinnamaldehyde, cinnamic alcohol and amyl cinnamic aldehyde,
 with the proviso that no other pesticidally-effective active ingredient is present. 
 
     
     
         24 . The method of  claim 23 , wherein the pest is a cockroach. 
     
     
         25 . The method of  claim 23 , wherein the plant essential oil compound is cinnamaldehyde. 
     
     
         26 . The method of  claim 23  wherein the plant essential oil compound is cinnamic alcohol. 
     
     
         27 . The method of  claim 23  wherein the plant essential oil compound is amyl cinnamic aldehyde. 
     
     
         28 . The method of  claim 23 , wherein the piperonyl butoxide and plant essential oil compound are present in a ratio of about 1:2 parts by weight.
