Insecticidal compositions

Abstract

The present invention relates to insecticidal mixtures of chloronicotinyl insecticides of the formula (I) in which R 1 represents C 1 -C 5 -alkyl, R 2 represents hydrogen or C 1 -C 5 -alkyl or R 1 and R 2 together represent —CH 2 —CH 2 —; —CH 2 —CH 2 —CH 2 — or X represents an NH group, NCH 3 group or represents sulphur, Y represents nitrogen or a CH group and Z represents cyano or nitro, with one or more of the synergists mentioned in the description.

1 - 6 . (canceled)  
     
     
         7 . An insecticidal mixture comprising synergistically effective amounts of the compound of formula (I)  
       
         
           
           
               
               
           
         
         wherein  
         R 1  represents C 1 -C 5 -alkyl,  
         R 2  represents hydrogen or C 1 -C 5 -alkyl  
         or  
         R 1  and R 2  together represent —CH 2 —CH 2 —; —CH 2 —CH 2 —CH 2 — or  
         
           
             
             
                 
                 
             
           
         
         X represents an NH group, NCH 3  group or represents sulfur,  
         Y represents nitrogen or a CH group and  
         Z represents cyano or nitro,  
         with  
         O-ethyl O-(4-bromo-2-chlorophenyl)-s-#N-propyl thiophosphate [Curacron].  
       
     
     
         8 . The insecticidal mixture of  claim 7  wherein the compound of the formula (I) is selected from the group consisting of the following:  
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
       
     
     
         9 . The insecticidal mixture of  claim 7  wherein the compound of the formula (I) is selected from the group consisting of the following:  
       
         
           
           
               
               
           
         
       
     
     
         10 . A process for preparing an insecticidal composition comprising mixing the insecticidal mixture of  claim 7  with at least one of extenders and surface-active agents.  
     
     
         11 . An insecticidal composition comprising the insecticidal mixture of  claim 7  and at least one of an extender and a surface active agent.  
     
     
         12 . An insecticidal composition comprising between 0.1 and 95 percent by weight of the insecticidal mixture of  claim 11 .  
     
     
         13 . A method of controlling at least one of insects, arachnids and nematodes comprising administering to the at least one of insects, arachnids and nematodes or to their locus a synergistic pesticidally effective amount of the mixture of  claim 11.
