Liquid Termiticide Compositions of Pyrethroids and Neonicitinoids

Abstract

The present invention relates to liquid termiticide compositions comprising a pyrethroid and a neonicotinoid selected from the group consisting of imidacloprid, nithiazine, thiamethoxam, dinotefuran, nitenpyram, thiacloprid and clothianadin, these compositions result in an increase in termite mortality at low application rates and a continuous chemical barrier of a termiticide in soil surrounding and beneath a structure in a locus where termites are suspected or known to exist.

         28 . A method for controlling termites comprising applying a termiticidally effective amount of a termite composition dispersed in an aqueous medium to a locus where termite control is needed or expected to be needed, wherein said locus is selected from a termite-infested structure, a structure that is expected to be termite-infested, or a location adjacent to said structures, and wherein:
 (a) the termiticide consists of a mixture of
 (i) a pyrethroid selected from the group consisting of: cypermethrin, zeta cypermethrin, lambdacyhalothrin, betacyhalothrin, alphacypermethrin, tralomethrin, deltamethrin, cyfluthrin, beta-cyfluthrin, esfenvalerate, fluvalinate, etofenprox and permethrin; and 
 (ii) a neonicotinoid selected from the group consisting of imidacloprid, nithiazine, thiamethoxam, dinotefuran, nitenpyram, thiacloprid and clothianadin; 
   (b) the amount of pyrethroid is equal to from 0.0005% by weight to 0.50% by weight of all components in the composition; and,   (c) the amount of neonicotinoid is equal to from 0.0005% by weight to 0.50% by weight of all components in the composition.   
     
     
         29 . The method of  claim 28  wherein the weight ratio of pyrethroid:neonicotinoid is between 1:2 and 1:20. 
     
     
         30 . The method of  claim 28  wherein the amount of pyrethrin is equal to from 0.001% by weight to 0.005% by weight of all components in the composition and the amount of neonicotinoid is equal to from 0.01% by weight to 0.02% by weight of all components in the composition. 
     
     
         31 . The method of  claim 28  wherein such termites are of the species  Reticulitermes flavipes.
