Abstract

This invention provides a method of combating termites at a locus, which comprises treating the locus e.g. soil or timber with an acyl urea of the formula ##STR1## wherein one substituent X is a halogen atom or a merthyl group and the other is a halogen atom, a hydrogen atom or a methyl group, and each of R¹, R² and R³ independently represents a hydrogen or fluorine atom; the use of acyl ureas of formula I for combating termites; and compositions for protecting timber against termite attack.

Claims

1. A method of combating termites at a locus infested with termites, said method comprising treating said locus with a termiticidally effective amount of an acyl urea of the formula ##STR7##

2. The method of claim 1 wherein the locus comprises soil or timber infested with termites.

3. The method of claim 2 wherein said soil or timber is treated with said acyl urea by application of a composition comprising said acyl urea and a carrier.

4. A method of protecting a locus subject to termite attack against such attack, said method comprising treating said locus with an amount of acyl urea compound of the formula ##STR8##

5. The method of claim 4 wherein said locus comprises soil or timber.

6. The method of claim 5 wherein said soil or timber is treated with said acyl urea by application of a composition comprising said acyl urea and a carrier.

7. Timber impregnated at least at a surface with a termiticidally effective amount of a termiticidally effective acyl urea compound having the formula ##STR9##
