Substituted phenylnitramines with plant growth regulating properties.

摘要

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: <CHEM> wherein R1 is halogen, C1-C4 alkyl, CN, CO2CH3, SO2CH3, SO2F, SO2CF3, C1-C3 haloalkyl, C1-C3 haloalkoxy or NO2; R3 is halogen, methyl or methoxy; R5 is halogen, CF3, methoxy or C1-C4 alkyl; with the proviso that not more than two of said R groups may represent fluorine, or an ammonium salt thereof.
