The invention relates to herbicidal compositions containing a glyphosate type herbicide and a phenoxybenzoic type herbicide, preferably acifluorfen-sodium, the ratio by weight of phenoxybenzoic type herbicide:glyphosate type herbicide ranging between about 1:12 and about 1:80. The compositions are relatively fast-acting and resistant to being washed out during rainfall occurring shortly after application. The invention also relates to a method of weed control employing the compositions.

Herbicidal compositions based on a glyphosate herbicide and acifluorfen

Sulphonylurea-type herbicides

Herbicidal compounds of the formula: ##STR1## in which R.sup.1 denotes an optionally substituted hydrocarbon radical, R denotes the hydrogen atom or has one of the meanings given for R.sup.1, R.sup.2 and R.sup.3 denote the hydrogen atom or are such that OR.sup.2 and OR.sup.3 are hydrolyzable groups; R.sup.4 denotes a hydrogen atom or a hydrogenolyzable group, and the agriculturally acceptable salts of these compounds.

N-sulphonyl-N-(N'-phosphonomethylglycyl)amine

Herbicidal compounds of formula: ##STR1## in which R.sup.1 denotes an optionally halogenated alkyl radical containing from 1 to 4 carbon atoms,

2-Methylenesuccinamic acid compounds are useful plant growth regulants, e.g., are useful in regulating the growth of soya crops.

2-Methylenesuccinamic acid compounds as plant growth regulants

The invention relates to new 2,3-dihydro-4-pyrone derivatives. These compounds correspond to the formula: ##STR1## in which R.sub.2 represents an alkyl radical (C.sub.2 -C.sub.3) and R.sub.3 represents and alkyl radical (C.sub.1 -C.sub.4), an alkenyl radical (C.sub.3 -C.sub.5) or an alkynyl radical (C.sub.3 -C.sub.5). They can be used for destroying weeds in crops, in particular sunflower and cotton crops.
