Abstract:
Herbicidal compositions, containing as an active ingredient herbicidally effective amounts of phosphinotricine derivatives of the formula ##STR1## in combination with simazin wherein the proportion by weight of the phosphinotricine derivative and simazin is in the range of from 1:1.5 to 1:4, exhibit a synergistic herbicidal effect.
Abstract:
Compositions containing (I) chlorophenoxy-phenoxy-.alpha.-propionic acid (esters) and (II) 3-methoxy-carbonylaminophenyl-N-(3'-methylphenyl)-carbamate as active ingredients are used as synergistic herbicides against grassy and broad-leaf weeds.
Abstract:
Optically active enantiomers of the formula I ##STR1## where R is a group of the formulae ##STR2## R.sub.1 and R.sub.2, among others, are halogen or CF.sub.3 and Z is a carboxyl, carboxylate, carboxylic acid ester, thioester, carbonamide, carboxylic acid anilide, carbohydrazide or thioamide group, are interesting herbicides the effect of which is considerably superior to that of the optically inactive racemates.
