The invention relates to substituted phenylnitramins with plant growth regulating properties, and to the use of these compounds for the control of relative growth of graminaceous crops, leguminous crops and cotton, especially for reducing the relative stem growth and increasing stem stiffness. The plant growth regulating phenylnitramines have the formula:n wherein R, is halogen, C 1 -C 4 alkyl, CN, CO 2 CH 3 , SO 2 CH 3 , S0 2 F, SO 2 CF 3 , C 1 -C 3 haloalkyl, C 1 -C 3 haloalkoxy or NO 2 ; R 3 is halogen, methyl or methoxy; R 5 is halogen, CF,, methoxy or C 1 -C 4 alkyl; with the proviso that not more than two of said R groups may represent fluorine, or an ammonium salt thereof. |
