Die erfindungsgemäßen herbiziden Mittel können Menge hängt von mehreren Faktoren, z. B. dem
zwar als solche zur Bekämpfung von unerwünschtem 45 Bodentyp, der durchschnittlichen Regenmenge und
Pflanzenwachstum eingesetzt werden, doch ist es im dem Alter des Unkrauts, ferner von den Bestandteilen
allgemeinen günstiger, sie mit einem geeigneten Träger des herbiziden Mittels und ihrer mengenmäßigen Zuzu
verwenden. Sie können beispielsweise mit einem sammensetzung ab. Auf jeden Fall sollte sie für eine
inerten Feststoff, wie Talkum, Ton, Diatomeenerde, entsprechende Fläche bzw. zur Benetzung oder Be-Vermiculit,
Walnußschalenmehl, Calciumcarbonat so stäubung des Unkrauts ausreichen. Im allgemeinen
oder mit einer lösenden bzw. nichtlösenden inerten werden zur Erzielung einer geeigneten herbiziden
Flüssigkeit gestreckt werden. Auch Emulgatoren, Wirkung weniger als etwa 5,6 kg/ha bis nur 0,56 kg/ha
Netz- und/oder Dispergiermittel können zugesetzt oder 0,84 bis etwa 1,12 kg/ha ausreichen,
werden. Die Konzentration an aktivem herbizidem Es wurde festgestellt, daß die erfindungsgemäßen
Mittel in den aufgeführten Zusammensetzungen kann 55 herbiziden Mittel besonders wirksam gegen uner-0,1
bzw. 95 Gewichtsprozent betragen, wobei die wünschtes Pflanzenwachstum solcher botanischer Ar-Konzentration
von der mengenmäßigen Zusammen- ten sind, die gegen 3,5-Dibrom-4-hydroxy-benzonitril
setzung und den Bestandteilen des herbiziden Mittels und dessen Derivate resistent sind. Sie sind jedoch
abhängt. Vorzugsweise verwendet man etwa 0,5 bis allgemein anwendbar und erlauben eine gute bis
95 Gewichtsprozent des aktiven herbiziden Mittels. 60 hervorragende Unkrautkontrolle praktisch aller Un-Wäßrige
Zusammensetzungen werden vorzugsweise krautarten in Getreidefeldern,
mit einem Gehalt von bis zu 360 g aktiven Bestand- Die folgenden Beispiele erläutern die Wirkung verteilen
je Liter Lösung angesetzt. Zur Erleichterung von schiedener erfindungsgemäßer herbizider Mittel. Die
Transport und Handhabung ist es darüber hinaus erhaltenen Ergebnisse sind in einer Wertskala von
günstig, Konzentrate mit wenigstens 25 Gewichts- 65 0 bis 10 aufgeführt, wobei 0 keinen meßbaren Effekt,
prozent und vorteilhaft unter etwa 90 Gewichteprozent der Wert 1 einer 10%igen, der Wert 2 einer 20%igen
des herbiziden Mittels herzustellen. Die für die ge- Pflanzenvernichtung usw., der Wert 10 also einer
wünschte herbizide Wirkung jeweils anzuwendende 100%igen Vernichtung entspricht.The herbicidal compositions according to the invention can amount depends on several factors, e.g. B. which are used as such to combat undesirable 45 soil type, the average amount of rain and plant growth, but at the age of the weeds, it is generally more favorable to use them with a suitable carrier of the herbicidal agent and their quantitative addition . For example, you can start with a composition. In any case, it should for inert solids such as talc, clay, diatomaceous earth, corresponding area or for wetting or Be vermiculite, walnut shell, calcium carbonate so dusting the weeds is sufficient. Generally or with a solvent or non-solvent inert will be stretched to achieve a suitable herbicidal liquid. Emulsifiers, effect less than about 5.6 kg / ha to only 0.56 kg / ha, wetting and / or dispersing agents can be added or 0.84 to about 1.12 kg / ha can be sufficient,
will. The concentration of active herbicidal It was found that the agents according to the invention in the compositions listed can be 55 herbicidal agents particularly effective against un-0.1 or 95 percent by weight, the desired plant growth of such botanical Ar concentration depending on the quantitative total are, the settlement against 3,5-dibromo-4-hydroxy-benzonitrile and the components of the herbicidal agent and its derivatives are resistant. You are, however, dependent. Preferably, from about 0.5 to generally applicable is used and allows as good as 95 percent by weight of the active herbicidal composition. 60 excellent weed control of practically all non-aqueous compositions are preferably herb species in grain fields,
with a content of up to 360 g of active ingredient- The following examples explain the effect of distributing per liter of solution. To facilitate various herbicidal compositions according to the invention. The transport and handling is moreover obtained results are on a scale of favorable, concentrates with at least 25 weight 65 0 to 10 listed, where 0 no measurable effect, percent and advantageously below about 90 weight percent the value 1 of a 10%, the value 2 to produce a 20% strength of the herbicidal agent. The 100% destruction to be applied in each case for plant destruction etc., ie the value 10 corresponds to a desired herbicidal effect.
2,4-D = 2,4-Dichlorphenoxyessigsäure. 2,4-DP = 2,4-Dichlorphenoxypropionsäure. MCPA = 2-Methyl-4-chlor-phenoxyessigsäure.2,4-D = 2,4-dichlorophenoxyacetic acid. 2,4-DP = 2,4-dichlorophenoxypropionic acid. MCPA = 2-methyl-4-chlorophenoxyacetic acid.
