Claims
- 1. A method for killing insects which comprises applying to said insects an insecticidal amount of the compound of the formula ##STR10## wherein R and R.sup.1 individually are alkyl, alkenyl or alkynyl of up to 6 carbon atoms and R.sup.2 is haloalkyl of 1 to 18 carbon atoms and of 1 to 4 fluorine, chlorine or bromine atoms, R.sup.3 is hydrogen or alkyl of 1 to carbon atoms and Y is oxygen or sulfur.
- 2. The method of claim 1 wherein R and R.sup.1 are alkyl of 1 to 3 carbon atoms, R.sup.2 is haloalkyl of 1 to 3 carbon atoms and 1 to 2 fluorine, chlorine or bromine atoms, R.sup. 3 is hydrogen and Y is oxygen.
- 3. The method of claim 2 wherein R and R.sup.1 are methyl.
- 4. The method of claim 1 wherein R.sup.2 is haloalkyl of 1 to 11 carbon atoms and of 1 to 2 chlorine or bromine atoms, R.sup.3 is hydrogen and Y is oxygen.
- 5. The method of claim 4 wherein R.sup.2 is halomethyl of 1 to 2 chlorine or bromine atoms.
- 6. The method of claim 5 wherein R and R.sup.1 are methyl.
- 7. The method of claim 6 wherein R.sup.2 is chloromethyl, bromomethyl or dichloromethyl.
- 8. The method of claim 4 wherein R.sup.2 is 3-chloropropyl or 10-bromodecyl and R and R.sup.1 are methyl.
- 9. An insecticidal composition comprising an insecticidal amount of the compound defined in claim 1 and a biologically inert carrier therefor.
- 10. The composition of claim 9 wherein R and R.sup.1 are alkyl of 1 to 3 carbon atoms, R.sup.2 is haloalkyl of 1 to 3 carbon atoms and 1 to 2 fluorine, chlorine or bromine atoms, R.sup.3 is hydrogen, and Y is oxgyen.
- 11. The composition of claim 10 wherein R and R.sup.1 are methyl.
- 12. The composition of claim 11 wherein R.sup.2 is haloalkyl of 1 to 11 carbon atoms and of 1 to 2 chlorine or bromine atoms and Y is oxygen.
- 13. The composition of claim 12 wherein R.sup.2 is halomethyl of 1 to 2 chlorine or bromine atoms.
- 14. The composition of claim 13 wherein R and R.sup.1 are methyl.
- 15. The composition of claim 14 wherein R.sup.2 is chloromethyl, bromomethyl or dichloromethyl.
- 16. The composition of claim 12 wherein R.sup.2 is 3-chloropropyl or 10-bromodecyl and R and R.sup.1 are methyl.
