Abstract
Substituted azabicycloalkanes of the formula I ##EQU1## wherein R represents an alkyl radical which contains 2 or 3 carbon atoms and is substituted by chlorine or a straight-chain or branched alkenyl radical containing 3 or 4 carbon atoms, R.sub.1 and R.sub.2 represent hydrogen or the one represents methyl and the other represents hydrogen, and n is the number 1 or 2, may be used for influencing the growth of plants, preferably for combating weeds in rice-cultures.
Claims11
A herbicidal composition which comprises (1) a herbicidally effective amount of a compound of the formula ##EQU5## wherein R is chloroalkyl having 2 or 3 carbon atoms or a straight chain or branched alkenyl having 3 or 4 carbon atoms, one of R.sub.1 and R.sub.2 is hydrogen and the other is hydrogen or methyl, and n is the number 1 or 2 and (2) an inert carrier.
A method for combating weeds which comprises applying to said plants a herbicidally effective amount of a compound of the formula ##EQU6## wherein R is chloroalkyl having 2 or 3 carbon atoms or a straight chain or branched alkenyl having 3 or 4 carbon atoms, one of R.sub.1 and R.sub.2 is hydrogen and the other is hydrogen or methyl, and n is the number 1 or 2.
A method for controlling the growth of weeds in cultures of wheat, soya, cotton and maize which comprises applying thereto a herbicidally effective amount of a compound of the formula ##EQU7## wherein R is chloroalkyl having 2 or 3 carbon atoms or a straight chain or branched alkenyl having 3 or 4 carbon atoms, one of R.sub.1 and R.sub.2 is hydrogen and the other is hydrogen or methyl, and n is the number 1 or 2.
A method for controlling the growth of weeds in rice cultures which comprises applying thereto a herbicidally effective amount of a compound of the formula ##EQU8## wherein R is chloroalkyl having 2 or 3 carbon atoms or a straight chain or branched alkenyl having 3 or 4 carbon atoms, one of R.sub.1 and R.sub.2 is hydrogen and the other is hydrogen or methyl, and n is the number 1 or 2.
