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:
wherein R, is halogen, C1-C4 alkyl, CN, CO2CH3, SO2CH3, S02F, SO2CF3, C1-C3 haloalkyl, C1-C3 haloalkoxy or NO2; R3 is halogen, methyl or methoxy; R5 is halogen, CF,, 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.
本发明涉及具有植物生长调节特性的取代苯基硝胺,以及使用这些化合物控制禾本科作物、豆科作物和棉花的相对生长,特别是减少茎的相对生长和增加茎的硬度。植物生长调节苯基硝胺的化学式为
其中,R 是卤素、C1-C4 烷基、CN、CO2CH3、SO2CH3、S02F、SO2CF3、C1-C3 卤代烷基、C1-C3 卤代烷氧基或 NO2;R3 是卤素、甲基或甲氧基;R5 是卤素、CF、甲氧基或 C1-C4 烷基;但上述 R 基团中不得有两个以上代表氟或其铵盐。
