Abstract: Compounds of formula (I): ##STR1## wherein: R.sup.1 is hydrogen, halogen or C.sub.1-4 alkoxy;X is oxygen; NR.sup.3 in which R.sup.3 is hydrogen, C.sub.1-4 alkyl, or -Y-R.sup.2 ; --C.dbd.O; or --CHOH;Y is --CH.sub.2 --CHOH, and when X is --C.dbd.O it may also be --CH.dbd.CH--; andR.sup.2 is C.sub.1-4 alkyl, one carbon atom of which is di- or tri-halogenated;or salts thereof, are useful in promoting growth of ruminants. Processes for their production, veterinary formulations and treatments are described.

Abstract: 2,3-Dichloro-7-hydroxy-1H-inden-1-one derivatives of the formula I ##STR1## wherein R.sub.1 is hydrogen or one of the groups ##STR2## R.sub.2 and R.sub.3 independently of one another are each hydrogen, fluorine, chlorine, bromine, C.sub.1 -C.sub.4 -alkyl, trifluoromethyl or nitro,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, andR.sub.5 is C.sub.1 -C.sub.6 -alkyl, C.sub.3 -C.sub.6 -cycloalkyl or C.sub.2 -C.sub.4 -alkenyl.These compounds exhibit a microbicidal action against in particular phytopathogenic fungi and bacteria.
