Abstract: Herbicidal compositions contain N-phosphonomethyglycine and alkyl phenol polyoxyalkylene surfactant which contains from about 50 to about 90 weight percent of alkyl phenol polyoxyethylene carboxylic acid.

Abstract: A synergistic herbicidal composition with residual activity comprises cycloate and cyanazine in a weight ratio of about 2:1 to 4:1, plus preferably a thiocarbamate herbicide antidote.

Abstract: Herbicide combinations with improved residual activity comprising (a) compounds of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of lower alkyl having from 2 to 6 carbon atoms, haloalkyl, benzyl and substituted benzyl, phenethyl, pyridylmethyl, cycloalkyl having from 3 to 6 carbon atoms, and haloalkenyl having from 3 to 6 carbon atoms, and R.sub.2 and R.sub.3 are each independently selected from the group consisting of C.sub.2 -C.sub.6 alkyl, C.sub.2 -C.sub.6 alkenyl, and C.sub.3 -C.sub.8 cycloalkyl, provided further that R.sub.2 and R.sub.3 can join with the nitrogen to which they are attached to form a 5 to 6 carbon ring structure, and (b) an herbicidally effective amount of a chloroacetanilide having the formula ##STR2## in which R.sub.4 is a straight or branched chain lower alkyl group having from 1 to 6 carbon atoms; R.sub.5 is a straight or branched chain lower alkyl group having from 1 to 6 carbon atoms; and R.sub.6 is ##STR3## where R.sub.

Abstract: A method is disclosed for the pre-emergent control of undesirable weed pests which comprises applying to the locus where control is desired by pre-emergent application of a herbicidally effective amount of the trimethylsulfonium salt of N-phosphonomethylglycine.

Abstract: A herbicidal composition comprising(a) a herbicidally effective amount of a tetraaluminum salt of N-phosphonomethylglycine; and(b) from 0.5 to 50% by weight polyethoxylated amine surfactant of the formula ##STR1## where R is tallow oil having an average of 18 carbon atoms and x+y total 15.

Abstract: The present invention is directed to a class of novel 1-benzoyl-3-thiosemicarbazides which are useful as plant growth regulants. The present invention is also directed to methods and formulations for plant growth regulation.

Abstract: Wild oats are killed over a substantial period of growth from two-leaf through four-leaf stages by applying post-emergently to the oats plants an effective amount of a combination of one part of barban with from about two to five parts, preferably three to four parts of CIPC, a herbicide which is normally applied pre-emergently.

Abstract: Certain noxious weeds, particularly yellow foxtail (Setaria glanca) and beggarweed (Desmodium torguosum) are combated in a number of crops by preemergent application of a synergistic combination of preferably about two parts by weight of N-benzyl-N-isopropylpivalamide with one part by weight of 2-cyclopropanecarboxamide-5-(2-chloro-1,1-dimethylethyl)-1,3,4-thiadiazole . Synergistic interaction of the two compounds is graphically illustrated by isobole charts of application rates which produce severe injury to specific weeds.
