METHOD OF CONTROLLING PLANT GROWTH WITH 3-SUBSTITUTED-PYRIDO {8 3,2-d{9 PYRIMIDINE-2,4-(1H,3H)-DIONES
Abstract
Abstract A method for controlling plant growth and compounds used in such method. The method includes the step of applying a composition comprising substituted pyrido(3,2-d) pyrimidine-2,4(1H,3H)-diones as herein described to the locus to be protected As new compositions of matter, 3-substitutedpyrido (3,2d)pyrimidine-2,4(1H,3H)-diones, where the 3-substituent is a member of the group consisting of alkyl groups having from 2 to 8 carbon atoms, dimethoxyethyl, aralkyl groups such as benzyl, chlorosubstituted benzyl, and lower alkyl and methoxy substituted benzyl, cycloalkyl groups having from 3 to 8 carbon atoms, pyridyl substituted alkyl groups having from 1 to 2 carbon atoms, alkenyl groups having not more than 8 carbon atoms, tetrahydrofurfuryl aryl, pyrrolidino, piperidino, homopiperdino, and septamethyleneimino, and 1,3-disubstituted analogues.
