This invention embodies a two-part herbicidal system comprised of an acylated 1,3-dicarbonyl herbicide compound corresponding to the formula ##STR1## and tautomeric forms thereof wherein R is an aromatic moiety, optionally substituted, and a non-phytotoxic antidotally effective amount of an antidote therefor selected from the group of amides of haloalkanoic acids, including oxazolidines and thiazolidines, aromatic oxime derivatives, thiazole carboxylic acids and derivatives, and 1,8-naphthalic anhydride.

Herbicidal compositions of acylated 1,3-dicarbonyl herbicides and

Novel S-benzyl thiolcarbamates are disclosed, having the formula ##STR1## in which R.sup.1 is selected from the group consisting of hydrogen and methoxy,

S-benzyl thiolcarbamates and their use in controlling weeds in rice

A method of increasing the yield of plants utilizing a compound of the formula ##STR1## wherein R is C.sub.3 -C.sub.14 alkyl or C.sub.3 -C.sub.6 alkenyl and R.sub.1 is hydrogen, C.sub.1 -C.sub.3 alkyl or phenyl.

Method of increasing the yield of plants utilizing

Novel phosphonium salts of N-phosphonomethylglycine are disclosed herein, having the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from the group consisting of C.sub.1 -C.sub.10 alkyl benzyl, phenyl, substituted phenyl and substituted benzyl wherein said substituents are independently selected from halogen, lower alkoxy, and lower alkyl; provided that at least one of R.sup.1, R.sup.2, R.sup.3, or R.sup.4 is benzyl, substituted benzyl, or substituted phenyl. The compounds are useful as herbicides and plant growth regulants.

Phosphonium salts of N-phosphonomethylglycine and their use as

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of --CH.sub.3, --C.sub.2 H.sub.5, --C.sub.3 H.sub.7 and --C.sub.4 H.sub.9, and R.sub.2 and R.sub.3 are independently selected from the group consisting of --OCH.sub.3, --OC.sub.2 H.sub.5 and --OC.sub.3 H.sub.7.

Method of increasing the yield of legumes utilizing O,O-dialkyl

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1## where R is chloromethyl or dichloromethyl; R.sup.1 is lower alkyl, vinyl or phenyl; R.sup.2 is hydrogen or lower alkyl and R.sup.3 is hydrogen or lower alkyl.

Method of increasing the yield of legumes utilizing

A method of increasing the yield of legumes (soybeans) utilizing a compound of the formula ##STR1## wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of --OCH.sub.3, --OC.sub.2 H.sub.5, --OC.sub.3 H.sub.7, and --OC.sub.4 H.sub.7.

Novel phosphonium salts of N-phosphonomethylglycine are disclosed herein, having the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from the group consisting of C.sub.1 -C.sub.10 alkyl and phenyl. The compounds are useful as herbicides and plant growth regulants.

The di-triethylamine salt of N,N'-bis-carboethoxymethyl-N,N'-bis-phosphonomethylurea is disclosed herein, having utility in regulating the natural growth or development of plants.

Di-triethylamine salt of

Novel amine salts of substituted N-phosphonomethylureas are disclosed herein, having the formula ##STR1## in which R, R', and R' are independently C.sub.1 -C.sub.4 alkyl;
