Description

The present invention relates to a herbicide which contains a mixture of active ingredients.

It is known that benzothiadiazinone dioxides (DT-PS 1 542 836) and substituted phenoxyacrylates (Derwent Central Patent Index, Section G, AGDOC, 1971, 4θ. Week, paper no.

64 4915-C, and Patent Quick Report Part B, Presentation B 32-278 / 68) have a herbicidal effect. Your herbicidal

However, effect is bad. · ·

It has been found that a mixture of a) compound of the formula

in which R is hydrogen and R. is lower alkyl and its salts and

b) a compound of the formula

-0-CH = CH-COO-R

in which R is a cycloalkyl radical optionally substituted by halogen or methyl with J> up to 12 carbon atoms, X denotes identical or different substituents from the groups halogen, methyl and methoxy and η = 0 to J5,

has a better herbicidal effect than the individual active ingredients. ^672/73 5.09830 / 0935 " ² "

The mixtures can contain one or more compounds of the formula a and compounds of the formula b.

The mixing ratios can be chosen as desired. The mixing ratio of the active ingredients a to b is for example 0.1 to 10 parts by weight of a to 1 part by weight of b, preferably 0.3 to 3 parts by weight of a to 1 part by weight of b.

The agents according to the invention can vary in the amount used. The amount used mainly depends on the type of effect you want. The application rate is generally between 0.1 and 30 or more, preferably 0.2 up to 6 kg of active ingredient per hectare. The agents according to the invention can be used, inter alia, in pre-planting, post-planting, pre-sowing, Pre-emergence, post-emergence or during emergence the cultivated or unwanted plants are applied one or more times.

The mixtures are suitable for use in useful plants, e.g. Oryza sativa, Triticum spp., Hordeum vulgare, sea eagles cereale, Zea mays, Sorghum spp., Glycine max, Solanum tuberosum, Cucumis satlvus, Pisum sativum, Allium cepa, Trifolium spp., Festuca spp., Poa spp. In addition, the mixtures can be used as a total mean on ditches, bodies of water, track systems, on bare areas, Wasteland etc. are applied.

The application takes place e.g. in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, grit, granules by spraying, misting, dusting, scattering or To water. The forms of application depend entirely on the intended use; in any case, they should ensure the finest possible distribution of the active ingredients according to the invention.

Medium-sized mineral oil fractions are used for the production of directly sprayable solutions, emulsions, pastes and oil dispersions to a high boiling point, such as kerosene or diesel oil, also coal rite oil etc. and oils of vegetable or animal origin

Powder, grit and dust can be mixed or mixed together Milling of the active substances with a solid carrier.

Granules, e.g. coating, impregnation and homogeneous granules, can be produced by binding the active ingredients to solid carriers. Solid carriers are e.g. mineral earth, such as silica gel, silicas, silica gels, silicates, talc, kaolin, attaclay, limestone, lime, chalk, talc, Bolus, loess, clay, dolomite, diatomaceous earth, calcium and magnesium sulfate, Magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, Urea and vegetable products such as cereal flours, tree bark, wood and nut shell flour, cellulose powder and others solid carriers.

if necessary, only added immediately before use (tank mix). The last-mentioned herbicidal compounds can also be used before or after the individual active ingredients or mixtures according to the invention will.

The admixture of these agents with the herbicides according to the invention can be in a weight ratio of 1:10 to 10; 1 take place. The same applies to oils, fungicides, nematocides, insecticides, Bactericides, antidotes and growth regulators.

The compositions have a strong herbicidal effect and can therefore be used as weed killers or for control unwanted vegetation can be used. Whether the remedies act as total or selective remedies depends mainly on the amount of active ingredient per unit area.
