Abstract
Plant growth regulating compounds are N-substituted-P-(2-chloroethyl)-phosphonamidic esters of the formula: ##EQU1## wherein R is cycloalkyl, R.sub.1 is hydrogen or cycloalkyl or R and R.sub.1 together form a heterocyclic ring such as morpholine, piperidine or pyrrolidine and R.sub.2 is alkyl or haloalkyl. They are prepared by the reaction of 2-chloroethylphosphonohalidic esters with the appropriate secondary amine.
Claims5
The method for stimulating plant growth which comprises contacting the plants to be treated with an effective amount of a substituted 2-chloroethyl phosphonamidic ester of the following formula:
- ##EQU16## wherein R is cycloalkyl of three to eight carbon atoms, R.sub.1 is hydrogen or cycloalkyl of three to eight carbon atoms and R.sub.2 is alkyl of one to seven carbon atoms or haloalkyl wherein alkyl contains one to seven carbon atoms, as active ingredient, in admixture with a suitable plant growth regulating carrier.
