- R.sub.4 is hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.4 -alkenyl, each of which is unsubstituted or substituted by halogen, or R.sub.4 is phenyl which is unsubstituted or is substituted by C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen, trifluoromethyl, cyano or nitro, or it is a C.sub.3 -C.sub.6 -cycloalkyl group.
- 2. A compound according to claim 1 wherein R.sub.2 is hydrogen, or in the 6-position it is nitro, fluorine, chlorine or bromine, or in the 5-position fluorine, chlorine or bromine; R.sub.3 is hydrogen, fluorine, chlorine, bromine or C.sub.1 -C.sub.4 -alkyl; and R.sub.4 is C.sub.1 -C.sub.4 -alkyl or C.sub.2 -C.sub.3 -alkenyl, each of which is unsubstituted or substituted by halogen.
- 3. A compound according to claim 2, wherein R.sub.2 is hydrogen, or in the 6-position it is nitro or halogen.
- 4. A compound according to claim 2 or 3, wherein in the formula I R.sub.4 is methyl or ethyl.
- 5. The compound 2,3-chloro-4-methyl-7-methylcarbamoyloxy-1H-inden-1-one.
- 6. A microbicidal composition containing as active ingredient an effective amount of a compound according to claim 1, together with suitable carriers.
- 7. A method for combatting microorganisms which comprises applying to said microorganisms or to the habitat thereof a pesticidally effective amount of a compound according to claim 1.
- 8. A method according to claim 7 wherein, in the compound,
- R.sub.2 is hydrogen; nitro, fluorine, chlorine or bromine in the 6-position; or fluorine, chlorine or bromine in the 5-position,
- R.sub.3 is hydrogen, fluorine, chlorine, bromine or C.sub.1 -C.sub.4 -alkyl, and
- R.sub.4 is C.sub.1 -C.sub.4 -alkyl or C.sub.2 -C.sub.3 -alkenyl, each of which is unsubstituted or substituted by halogen.
- 9. A method according to claim 8 in which, in the compound, R.sub.2 is hydrogen, or nitro or halogen in the 6-position.
- 10. A method according to claim 8 or 9 in which, in the compound, R.sub.4 is methyl or ethyl.
- 11. The method according to claim 10 in which the compound is 2,3-dichloro-4-methyl-7-methylcarbamoyloxy-1H-inden-1-one.
