摘要:
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-SUBSTITUTED-PYRIDO (3,2-D)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, DIMTHOXYETHYL, 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, HOMOPIPERIDINO, AND SEPTAMETHYLENEIMINO, AND 1,3-DISUBSTITUTED ANALOGUES.
