Abstract

New herbicides contain as active substance a combination of (a) an alkyl ester of 9-hydroxyfluorene-9-carboxylic acid (fluorenol); (b) an alkyl ester of 4-chloro-2-methylphenoxyacetic acid (MCPA); (c) N-(3,4-dichlorophenyl)-propionamide (prpanil); and (d) 2,6-dinitro-N,N-dipropyl-4-trifluoromethyl-aniline (trifluralin) or N3,N3-diethyl-2,4-dinitro-6-trifluoromethyl-1,3-benenediamine (dinitramin) or S- (4-chlorophenyl)methyl -diethylcarbamothioate(bentiocarb); together with (e) usual adjuvants and carriers. Selective herbicides for use in rice crops. The combination is well tolerated by rice and has strong herbicidal activity against broadleaved and grassy weeds, e.g. Echinochloa, Eleusine, Digitaria, Ipomoea, Amaranthus and Portulaca.

Die Anwendung geschieht in Form üblicher Zubereitungen.They are used in the form of customary preparations.

Geeignete Mengen der Wirkstoffe können beispielsweise zu Suspensionspulvern oder Emulsionskonzentraten verarbeitet und dann mit Wasser zu einer Spritzbrühe geeigneter Konzentration vermischt werden (Gesamtgehalt an Wirkstoff in der Spritzbrühe zwischen 0,05 und 1,0 Gewichtsprozent).Suitable amounts of the active ingredients can be added to suspension powders, for example or emulsion concentrates and then mixed with water to form a spray mixture suitable concentration are mixed (total content of active ingredient in the spray mixture between 0.05 and 1.0 percent by weight).

Die Wirkstoffkombinationen können auch vorteilhaft in Form von Tankmischungen eingesetzt werden.The active ingredient combinations can also advantageously be in the form of tank mixes can be used.

Die Anwendung der erfindungsgemäßen Mittel erfolgt im Nachauflaufverfahren, bei bewässertem Reis nach dem Ablassen des Wassers.The agents according to the invention are used post-emergence, for irrigated rice after draining the water.
