2-(Substituted phenylimino)imidazolidines of formula:
and their non-toxic salts in which R is C1-4 alkyl, C2-5 alkenyl, or halo, is hydrogen, C1-4 alkyl, or halo, is C1-4 alkanoyl, carboxy, (C1-3 alkoxy)carbonyl, C1-4 alkylthio, phenoxy, (C1-3 alkoxy)-phenoxy, halophenoxy, phenylthio, (C1-3 alkyl)-phenylthio, (C1-3 alkoxy)-phenylthio, halophenylthio, C1-4 hydroxyalkyl, (C1-3 alkoxy)-(C1-4 alkyl, di (C1-3 alkyl)amino-(C1-4 alkyl), C5-5 alkenyl, or di(C1-3 alkyl)amino are novel.
Compunds of formula:
and their non-toxic salts where R is defined above, each of R1 and R2 is independently a radical as defined for either of and or a nitro, amino, C1-3 alkylamino, di(C1-3 alkyl) amino, hydroxy, trifluormethylthio, C1-4 aminoalkyl or (C1- 3 alkyl)amino-(C1-4 alkyl) radical, are administered to poultry to delay the onset of egg production in young pullets and interrupt egg production in mature hens and are useful in producing an artificial moult. They are included in feeds, feed concentrates and additives for drinking water.
