HERBICIDE
The present ir.vantion relates to a herbicide comprising a
composition of active in~redients. It is known that benzothia-
diazinone dioxides and substituted urea derivatives have a
herbicidal action. However, this actior. is not always satis-
factory.
We have now fourd that a compositior. of
a) a compound of the formula
o
Rl
,S2
H
where Rl denotes lower alkyl, or a sal~ thereof,
and
b) a urea derivative selected from the group consisting
of N-3-chloro-4-isopropylphenyl-N~-methyl-N~-methoxy-
urea, 1~'-3-methyl-4-bromophenyl-NI,N~-dimethylurea,
N- [4-(4'-chlorophenoxy)-pher.yl~ ',N'-dimethylurea,
N-3-methyl-4-chlorophenyl-N',N'-dimathylurea ard

has a better herbicidal actior. than its components.
The compositions may contain one or more compounds of the
formula a and of the formula b.
The ratio oP the active ingredients to each other may be
selected at will, fro~ 0.1 to 10 ~arls bv wei~ht of a to 1
part by weight of b, and preferably from 0.3 to
3 parts by weight of a to 1 part by weight of b.
The amour.t usad of tha agents according to the ir-.vention
may vary and depends in esser.ce on the typa Or effect to be
achieved; it is generally from 0.1 to ~0 (ar.d more), prefer-
ably from 0.2 to ~, kg per hectare of active ingrediert. The
agents according to the invention may be used once or several
times ba~ore or after planting, before sowing, and before,
during or after emargence of the crop plants and ur.wanted
plants.
The compositions are selective ir. Triticum aestivum, Hor-
deum vulgare, Secale cereale, Zea mays, Sorghum spp., Glycine
max., Pisum sativum, Solanum tuberosum, and other crops.
The compositions may also be used as total herbicides on
ditches, aquatic areas, railroad tracks, and barren or waste
land, etc.
Applica~ion may be effected for instance in the form of
directly sprayable solutions, powders, suspensions, disper-
sions, emulsions, oil dispersions, pastes, dusts, broadcast-
ing agents, or granules by spraying, atomizing, dustir.g,
broadcasting or watering. The forms of application depend en-
tirely on the purpose for which the agents are bair.g used, in
any case they should er.sure a fine distribution of the active
ingredient.

For the preparation of solution~, emulsion~, pastes and
oil dispersions to be sprayed direct, mineral oil fractions of
medium to high boiling point, such as kerosene or die~el oil,
further coal-tar oils, etc. and oils of vsgetable or mineral
origin, aliphatic, cyclic and aromatic hydrocarbons such a~
benzene, toluene, xylene, paraffin, tetrahydronaphthalene,
alkylated naphthalenes and their derivatives such as methanol,
ethanol, propanol, butanol, chloroform, carbon tetrachloride,
cyclohexanol, cyclohexanone, chlorobenzene, isophorone, etc.,
and strongly polar solvents such as dimethylformamide, dimethyl
sulfoxide, N-methylpyrrolidone, water, etc. are suitable.
Aqueous formulations may be prepared from emulsion con-
centrates, pastes, oil dispersions or wettable powders by
adding water. To prepare emulsions, pastes and oil dispersions
the ingredients as such or dissolved in an oil or solvent may
be homogenized in water by means of wetting or dispersing
agents, adherents or emulsifiers. Concentrate~ which are
suitable for dilution with water may be prepared from active
ingredient, wetting agent, adherent, emulsifying or dispersing
agent and possibly solvent or oil.
Examples of surfactants are: alkali metal, alkaline
earth metal and ammonium salts of ligninsulfonic acid, naph-
thalenesulfonic acids, phenolsulfonic acids, alkylaryl sul-
fonates, alkyl sulfates, and alkyl sulfonates, alkali metal
and alkaline earth metal salts of dibutylnaphthalenesulfonic
acid, lauryl ether sulfate, fatty alcohol sulfates, alkali
metal and a~kaline earth metal salts of fatty acids, salts
of sulfated hexadecanols, heptadecanols, and octadecanols,
salts of sulfated fatty alcohol glycol ether, condensation

products of sulfonated naphthalena and naphthale-re derivati-
ves with formaldehyde, condensation products of naphthaler.e
or naphthalenesulfonic acids with phenol and formaldehyde,
polyoxyethylene octylphenol ethers, ethoxylated isooctyl-
phenol, ethoxylated octylphenol and ethoxylated nonylphenol,
alkylphenol polyglycol ethers, tributylphenyl polyglycol
ethers, alkylaryl polyether alcohols, isotridecyl alcohol,
fatty alcohol ethylene oxide condensates, ethoxylated castor
oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropyl-
ene, lauryl alcohol polyglycol ether acetal, sorbitol esters,lignin, sulfite waste liquors and methyl cellulose.
~ owders, dusts and ~roadcasting agents may be prepared
by mixing or grinding the active ingredients wlth a solid
carrier.
Granules, e.g., coated, impregnated or homogeneous gra-
nules, may be prepared by bonding the active ingredients to
solid carriers. Example~ of solid carriers are mineral earths
such as silica gel, silicic acid, silica gels, silicates,
talc, kaolin, Attaclay, limestone, lime, chalk, bole, loess, ~ -
clay, dolomite, diatomaceous earth, calcium sulfate, magne-
sium sulfate, magnesium oxide, ground plastics, fertilizers
such as ammonium sulfate, ammonium phosphate, ammonium nitra-
te, and ureas~ and vegetable products such as grain flours,
bark meal, wood meal, and nutshell meal, cellulosic powders,
etc.
The formulations contain from 0.1 to 95, and preferably
0.5 to 9r % by weight of active ingredient. --
There may ~e added to the compositions or individual
active ingredients (if desired, immediately before use (tank-

The last-mentioned herbicidal compounds may also be ap-
plied before or after the active ingredients or compositions
thereof according to the invention.
TheRe agents may be added to the herbicides according to
the invention in a ratio by weight of from 1:10 to 10:1. The
same applies to oils, fungicides, nematocides, insecticides,
bactericides, antidotes and growth regulators.
The new compo~ition~ have a strong herbicidal action and
may therefore be used as weedkillers or for controlling the
growth of unwanted plants. Whether the new active ingredients
are used as total or selective agents depends in essence on
the amount of ingredient used per unit area.
By weeds and unwanted plant growth are meant all mono-
cotyledonou~ and dicotyledonous plants which grow in loci
where they are not desired.
The agents according to the invention may therefore be
used for controlling for instance
Gramineae, such as
Cynodon spp. Dactylis spp.

I+VI and II+VI each at a rata of 1+2 kg/ha.
After 2 to 3 weeks it was ascertained that the compositions
I~V, II+V, III~V and IV+V had better crop plant compatibility
than VI and the compositions I+VI and II+VI, combined with the ~ -

EXAMPLE 4
In the greenhouse, various plants ware treated at a
height of from 4 to 20 cm with the following amounts of the
following individual active ingredients and compositions thereof
as aqueous solutions or dispersior.s:
I 3-isopropyl-2,1,3-benzothiadiazinone-(4)-2,2-dioxide
III 3-isopropyl-2,1,3-benzothiadiazinone-(4)-2,2-dioxide,
sodium salt
III N- [4-~4'-chlorophenoxy)-pheny~ -N',N'-dimethylurea
each at rates of 1, 1.5, 2 and 3 kg/ha;
I+III and II~III each at rates of ~+1, 1~2-and 1.5+1.5 kg/ha-
After 12 to 17 days it was ascertainad that the
compositions had a better herbicidal action than their
components, combined with the same crop plant compatibility.
