Wettable powder formulations of herbicides

Selective herbicidal composition

Herbicidal synergistic composition, and method of controlling weeds

Herbicidal synergistic composition and method of weed control

A herbicidal composition comprising, in addition to conventional inert formulation adjuvants, the compound of formula I

A herbicidal composition comprising a compound of formula A ##STR1## or an agrochemically acceptable salt thereof and at least one compound from the substance classes of formulae I-VII.

Herbicidal composition and method of weed control

A herbicidal synergistic composition, comprising, besides customary inert formulation auxiliaries, a compound of formula I ##STR1## and a synergistically active amount of at least one active ingredient selected from among the compounds of formula II ##STR2## and of formula III ##STR3## and of formula V ##STR4##

A herbicidal composition comprising, in addition to customary inert formulation adjuvants, as active ingredient a) an antagonistically active amount of at least one compound A selected from the group of compounds of formula A.sub.1 ##STR1## and compounds of formula A.sub.2 ##STR2## compounds of formula A.sub.3 ##STR3## b) a herbicidally effective amount of at least one compound G selected from the group of compounds, preferably having the 2R-configuration, of formula G.sub.1 ##STR4## compounds of formula G.sub.2 ##STR5## c) an acid the pK value of which is smaller than the pK values of compounds G and A.

Herbicidal composition and method of controlling weeds

A selective herbicidal composition for controlling grasses and weeds in crops of cultivated plants, comprising, in addition to inert carriers and adjuvants, as active component a mixture of a) a herbicidally effective mount of a N-phenylsulfonyl-N'-triazinylurea of formula I ##STR1## wherein the substituents are as defined in claim 1, and b) to antagonise the herbicide, an antidotally effective mount of a quinoline derivative of formula IIa ##STR2## wherein R.sub.10 is hydrogen, C.sub.1 -C.sub.8 alkyl or C.sub.1 -C.sub.8 alkyl which is substituted by C.sub.1 -C.sub.6 alkoxy or C.sub.3 -C.sub.6 alkenyloxy; and X.sub.2 is hydrogen or chloro; or of a 1-phenylazole-3-carboxylic acid derivative of formula IIb ##STR3## wherein E is nitrogen or methine; R.sub.11 is --CCl.sub.3, phenyl or halogen-substituted phenyl; R.sub.12 and R.sub.13 are each independently of the other hydrogen or halogen; and R.sub.14 is C.sub.1 -C.sub.4 alkyl.

Selective safened herbicidal composition

Compounds of the formula XI, wherein R, R.sub.4, R.sub.8 and R.sub.38 are as defined in claim 1, are useful as intermediates in the preparation of compounds of formula I. Mixtures of a herbicidally effective amount of a pyridylsulfonylurea of formula I, ##STR1## wherein R, R.sub.1, R.sub.2 and A are as defined in the specification and of a herbicide-antagonistically effective amount of a sulfamoylphenylurea of formula II, ##STR2## wherein R.sub.7 to R.sub.11 and A.sub.2 are as defined in the specification are very suitable for controlling weeds in crops of useful plants, especially maize and sugar cane.
