Abstract

Herbicidal preparations and procedures for the eradication of unwanted or harmful plants.

Description

The invention relates to new herbicidal preparations, which both show a rapid initial effect as well as an excellent permanent effect and a very broad spectrum of effects; the invention further relates to a new method for the eradication of unwanted and harmful plants.

In order to obtain a herbicide preparation with a quick initial effect and a good permanent effect, preparations are usually used which on the one hand contain water-soluble herbicidal active substances, whose effect occurs shortly after the plant treatment and on the other hand contain herbicidal active substances with low water solubility, such as e.g. s-triazine derivatives, the effect of which is only visible rather late.

The effect of such mixtures is usually predictable and, admittedly, it is mostly equal to the sum of the effect of each of the individual active components.

Such preparations are particularly mentioned in South African patent application no. 69/6446 and in Indian patent no. 7350.

They contain a quaternary bipyridylium salt such as lj^-dimethyl-^ir-bipyridylium dichloride (PARAQUAT DICHLORIDE), as well as a herbicidally active substance that inhibits the plants' photosynthesis, e.g. an s-triazine derivative such as 2-chloro-4,6-bis-ethylamino-s-triazine (SIMAZIN) and also possibly a hormone such as e.g. the salt of a halogenated carboxylic acid.

The herbicidal effect of these known preparations is always equal to the sum of the effect of the individual herbicidal components in the mixture.

The task of the invention is to provide herbicidal preparations with improved effect, especially with the advantage that the herbicidal effect is visible against the most diverse weeds (both monocotyledonous and dicotyledonous plants) already a few days after application and is maintained to a practically full extent over several months .

It has been found that a herbicide preparation containing (A) approx. 10 to 80 parts by weight of 2,2'-ethylene-1,1'-. bipyridylium dibromide (DIQUAT. DIBROMIDE) with, formula

and (B) 100 parts by weight of 2-chloro-4-ethylamino-6-t-butylamino-s-triazine (TERBUTYLAZINE) with formula as well as possibly complementary acting herbicides (C) and/or additives (D), all parts by weight referring to the weight of the pure active substances (A) and (B), has a much faster initial effect than what was expected from the sum of the effects of the two individual components. The preparation according to the invention contains: (A) Ga. 0.1 to 65 parts by weight DIQUAT-DIBROMIDE (1005g-ig active substance). (B) Approx. 0.1 to 80 parts by weight TERBUTYLAZINE (lOOjK-ig active substance). (C) 0 to approx. 30 parts by weight of one or more complementary acting herbicides and (D) approx. 5 to 98.9 parts by weight of one or more additives.

Preferably, the preparations according to the invention contain:

(A) Approx. 10 to 20 parts by weight DIQUAT DIBROMIDE.

(B) Approx. 30 to 60 parts by weight TERBUTYLAZINE.

(C) Approx. 0 to 10 parts by weight of one or more complementary acting herbicides. (D) Approx. 10 to 60 parts by weight of one or more additives.

The mixture.*v& v TERBUTYLAZINE and DIQUAT DIBROMIDE .

thus has an unexpectedly high synergistic herbicidal effect, which none of the previously known similar mixtures have.

The invention further relates to a new method for exterminating grass and unwanted or harmful plants, the method being characterized in that on each m<2>surface that is overgrown with plants to be eradicated an amount of approx. 0.1 to 100 g, preferably from 0.35 to 91 g of an above-mentioned herbicidal preparation.

Preferably, the amount of the mixture of the components (A) + (B), which is used in the method according to the invention, amounts to 0.3 to 1 g/m of the surface covered with weeds.

The preparations' according to the invention can be used

in the form of emulsions, oily or aqueous suspensions or in the form of organic solutions, e.g. in the usual spraying or atomizing devices, especially pressure containers (Aerosol containers). The preparations according to the invention can also be used in the form of granules or water-dispersible powders. If the preparations according to the invention are diluted before use in water, then 0.5 to 3 g of this is added to 0.1 to 2 liters of water.

Preferably, the preparations according to the invention are used for the complete eradication of all on specific surfaces, such as e.g. on squares, streets, roads, tracks, etc. plants present, i.e. as a total herbicide.

The preparations according to the invention can also be used for the eradication of randomly occurring plants on relatively limited surfaces, such as in avenues, footpaths, fences, garden beds, etc. In this case, it is particularly advantageous to use the preparations according to the invention by means of atomizing wax and to use them locally at the plants that you want to suppress.

Such a method has the advantage that very little herbicide is needed, an advantage in economic and ecological terms.

In addition to the substances (A) and (B), the preparations according to the invention may also contain other herbicidally active compounds (C), especially those with complementary herbicidal effects in comparison to (A) and (B).

The most diverse additives (D) are also possible without a herbicidal effect. Alongside other additives that can be used as herbicides, agents against animal pests, e.g. nematocides and insecticides. However, particularly suitable for use are (1) organic or inorganic compounds, which are solvents or diluents for the components (A),

(B) and (C),

(2) emulsifier,

(3) corrosion inhibitors,

(4) dyes, as well as where applicable

(5) propellant and/or

wherein X means 1 to 4 chlorine atoms and/or bromine atoms and R means a hydrogen atom, a methoxy or a methyl group, m is equal to 0 or 1 and n is equal to 1, 2 or J>.

The esters formed with the acids of formula III preferably originate from a primary or secondary alkanol with 1 to 12 carbon atoms or an alkoxyalkanol with a total of 3 to

As indicated, however, the presence of a further

■herbicide' (C) not necessary for a good and persistent effect, thus compositions containing only the mentioned herbicides

(A) and (B), in many cases are preferred.

As additives (D), it can e.g. are used

the following compounds:

(1) Volatile, liquid organic or mineral compounds that serve as solvents or diluents for the other compounds present in the preparations

(A) and'(B) and especially for the complementary-acting herbicides (C) or non-volatile or low-volatile liquids which then especially

serves to retain the active substances for the plants that are intended for extinction..

(2) Emulsifiers, which are added with water

non-miscible preparations according to the invention, in order to use these to produce aqueous diluted emulsions or (3) corrosion inhibitors which can be added to reduce or avoid the corrosion effect of the preparations according to the invention on packages or devices or equipment used for their production or application or (4) colorants that serve to lighten the characteristics of treated plants or surfaces and/or as warning colors;

(5) propellants which are added in an aerosol container to the preparations according to the invention and which make it possible to distribute the preparations according to the invention on the plants in the form of a

aerosol; (6) solid powdered or granulated diluents which serve as carriers and enable the compositions according to the invention to be used as spray powders or granules; (7) denaturants can be used in the preparations according to the invention such as e.g. sulfur-containing or nitrogen-containing, especially heterocyclic compounds such as skatole, indole or benzyldiethyl-(2,6-xylylcarbamoylmethyl)-ammonium benzoate.

Among the volatile compounds from group (1), the following are particularly applicable: Water, lower alcohols such as methyl alcohol, ethyl alcohol and isopropyl alcohol, ketones such as acetone, methyl ethyl ketone and cyclohexanone, aromatic hydrocarbons such as tetrahydronaphthalene, alkylated derivatives of naphthalene, benzene, toluene and xylene, non-halogenated aliphatic hydrocarbons such as kerosene, halogenated, especially chlorinated hydrocarbons such as dichloromethane, trichloromethane, trichloroethylene and perchloroethylene, oxygen-containing heterocyclic compounds such as dioxane, aliphatic carboxylic acid amides such as dioxane, aliphatic carboxylic acid amides such as dimethylformamide and dimethylacetamide as well as esters, which are formed from alkanecarboxylic acid and alkanols and which together have between 3 and 15 carbon atoms, such as methyl acetate, ethyl acetate, butyl acetate, amyl acetate, ethyl propionate, ethyl butyrate, ethyl heptanoate, butyl heptanoate, heptyl heptanoate, ethyl caprylate, methyl caprine, ethyl caprine, methyl laurate, ethyl laurate, isopropyl laurate and methyl myristate. Of group (1), mention can also be made of dimethylsulfoxide.

The vapor pressure of these compounds at 20°C is 0.02 mbar or higher.

As low or non-volatile liquids from group 1, those whose vapor pressure at 20°C is less than 0.02 mbar and especially those whose vapor pressure is less than 0.002 mbar are preferred above all.

These are, for example, mineral oil, vegetable oil, animal oil and liquids, which are usually used for plasticizing polymeric resins, such as in particular chlorohexadecane, chlorooctadecane, dioctyl adipate, dibutyl sebasate, dioctyl sebasate, dioctyl azelate, dibutyl phthalate, dioctyl phthalate, didecyl phthalate, diphenyl phthalate, dicresyl phthalate, dicyclohexy phthalate, dibenzyl sebasate, triphenyl phosphate, tricresyl phosphate and trioctyl phosphate.

The emulsifiers (2) which can be used in the preparations according to the invention are particularly cationic and/or non-ionic and/or ampholytic surfactants (surfactants).

Cationic surfactants belong to e.g. to the following classes: quaternary ammonium salts, e.g., bis-quaternary ammonium salts, amines, amine salts, long-chain imidazolines, imidazolium salts, pyridinium, morpholinium, quinolinium salts and their ethoxylated derivatives.

Such cation-active surfactants are in particular the alkyltrimethyl, dialkyldimethyl and alkyldimethylbenzylammonium salts, whose alkyl groups contain 8 to 22, preferably 12 to 18, hydrocarbon atoms such as e.g. tetradecyltrimethylammonium bromide, hexadecyltrimethylammonium bromide, cetyltrimethylammonium chloride, octadecyltrimethylammonium chloride, an alkylItr-methylammonium chloride, the alkyl residues of which correspond to the alkyl residues of coconut fatty acids; ethyl1-dodecyl-dimethylammonium bromide, disteary1-dimethylammonium chloride, lauryldimethylbenzylammonium chloride; hexadecyltrimethylamine; octadecylpyridinium chloride, tetradecylpyridinium iodide; polyethoxylated stearyl amine diethanol ammonium chloride, cetyl ethyl morpholinium methosulfate.

Furthermore, ampholytic surfactants, long-chain N-alkylated 8-aminopropionic acids, glycines, betaines, sulfated imidazoline derivatives and condensates of sulforaic acid esters with taurine may also be suitable as emulsifier (2).

These ampholytic compounds include e.g. the sodium salt of N-cocofatty acid-3-aminopropionic acid, N-lauryl-6-aminopropionic acid, N-laurylmyristyl-B-aminopropionic acid and the tri-ethanolamine salt of N-laurylmyristyl-3-aminopropionic acid and its glycines and betaines.

The corrosion inhibitors (3) are added to the preparations according to the invention, especially when the latter are stored in pressure vessels or in metallic packaging.

Such inhibitors are especially long-chain aliphatic acids and their salts, morpholine derivatives, etc. as long as these additives are compatible with DIQUAT DIBROMIDE.

The propellants (5) used in the preparations according to the invention are e.g. butane, isobutane, propane, carbon dioxide, trichlorofluoromethane, dichlorodifluoromethane, 1,2-dichloro-1,1,2,2-tetrafluoroethane, tetrafluoromethane and/or octafluorocyclobutane..

The following examples of preparations according to the invention and with the experiments carried out serve to explain the invention in more detail, as the quantities are everywhere stated in parts by weight of pure active substance.

Coverage rate in % means:

Ground surfaces covered by weeds in % of the total ground surface.

Evaluation form by efficiency with rating numbers 1-9:

Experiment A.

Several plots, which were covered with different species of Gramineen and dicotyledonous plants, were treated with the following active substances:

(A) DIQUAT DIBROMIDE (a)

(B) TERBUTYLAZINE (b)

• (C1) AMETRYNE (c)

(C2) SIMAZINE (d)

(a) 2,2'-ethylene-1,1'-bipyridylium dibromide; (b) 2-chloro-4-ethylamino-6-t-butylamino-s.triazine; (c) 2-chloro-4-isopropylamino-6-ethylamino-s.triazine;

(d) 2-chloro-4,6-diethylamino-s.triazine.

The effect of the mixture of the preparations according to the invention containing the compound (A) + (B) compared to the effect of each of the single active substances (A) and (B).

The results were determined in time intervals of 2,

5, 15 and 19 days and each result assessed on a scale from 1 to 9, with 9 meaning no herbicidal effect and 1 meaning a complete eradication of the plant growth.

One parcel was not treated for control and comparison.

The preparations compared were prepared from the following aqueous concentrates 1 to 10 by diluting one part by weight of the concentrate in 50 - 1000 parts by weight of water, all percentages referring to the total weight of the concentrate.

The results of the experiment are listed in the following tables II and III.

The results of these tests show that the most effective mixtures (A) + (B) are obtained when approx. 4-8 parts by weight. DIQUAT-DIBROMIDE is mixed with approx. 1 part by weight of TERBULAZIN and when the thus formed mixture is distributed in an amount from 0.3 to 2 g/m<2>and preferably from 0.3 to 1 g/m 2on the soil covered with weeds.

Moreover, these results show that no synergistic herbicidal effect occurs when TERBUTYLAZINE is replaced with AMETRYN.

In the following tables IV and V further trials are described, as the same scale of herbicidal effect was used as when determining the results stated in the first tables.

The results shown in Tables IV to V showed very clearly that the initial effect of the preparations according to the invention is a synergistic effect.

However, this synergistic effect is no longer observed when SIMAZINE is used instead of TERBUTYLAZINE.
