The selective growth of rice in paddies is promoted by applying thereto a composition comprising

Promoting selective growth of rice in paddies

4-CHLOROBENZYL-N,N-hexamethylenethiolcarbamate has been found to be uniquely active and selective in the control of weeds, particularly in crop cultivations such as rice paddies.

Herbicidal methods using 4-chlorobenzyl-N,N-hexamethylenethiolcarbamate

Certain thiolcarbamate compounds of the general formula ##STR1## wherein X is alkyl, e.g., lower alkyl, e.g., of from 1 to 4 carbon atoms, lower alkoxy of from, e.g., 1 to 3 carbon atoms, or halogen, e.g., chlorine or bromine, preferably chlorine. When n is greater than 1, the various radicals X may be the same or different, with provisos.

Benzyl N,N-hexamethylenethiolcarbamate compounds and herbicidal

Certain novel thiolcarbamate compounds of the general formula ##STR1## wherein X is alkyl, e.g., lower alkyl, e.g., of from 1 to 4 carbon atoms, lower alkoxy of from, e.g., 1 to 3 carbon atoms, or halogen, e.g., chlorine or bromine, preferably chlorine. When n is greater than 1, the various radicals X may be the same or different, with provisos.

P-Chlorobenzyl N,N-hexamethylenethiolcarbamate

Amidothionophosphonic acid ester compounds of the formula: ##STR1## in which R is alkyl of from 1 to 6 carbon atoms or lower cycloalkyl;

Novel amidoth ionophosphoric acid esters and their use as herbicides

Certain new cyclohexyl carbamates of the formula: ##EQU1## wherein X is hydrogen, halogen, lower alkyl or lower alkoxy,

Novel cyclohexyl carbamates and herbicidal and acaricidal compositions

Alkoxy-substituted benzyl dithiocarbamic acid esters, i.e. [(optionally mono- and di- alkyl, alkoxy, nitro, chloro and bromo substituted)-(alkoxy substituted)-benzyl]-dithiocarbamates, which possess herbicidal properties and which may be produced by conventional methods.

Alkoxy-substituted benzyl dithiocarbamic acid esters

Phosphoro-amido-thioates, i.e. O-alkyl-O-[2-nitro-4-(alkyl, alkoxy and chloro)-phenyl]-N-alkyl-phosphoro-amido-thioates and O-alkyl-O-[2-nitro-4-(optionally alkyl, alkoxy and chloro)-phenyl]-N-cycloalkyl-phosphoro-amido-thioates, or O-alkyl-O-[2-nitro-4-(alkyl, alkoxy and chloro)-phenyl]-N-alkyl-amido-thionophosphates and O-alkyl-O-[2-nitro-4-(optionally alkyl, alkoxy and chloro)-phenyl]-N-cycloalkyl-amido-thionophosphates, which possess herbicidal properties and which may be produced by conventional methods.
