Herbicidal sulphonylimino-azinlyheteroazoles of the formula
Herbicidal sulphonylimino-azinlyheteroazoles of the formula
Description
The invention relates to new sulphonylimino-azinylheteroazoles, a process and new intermediates for their preparation and their uce as herbicides.
It is known that 3-amino-1,2,4-triazole (amitrol) can be used as a herbicide (compare Science 145 (1964), 97). However, the action of this compound is not satis-factory in all matters.
The new sulphonylimino-azinylheteroazoles of the general formula (I) z~y ~ 2 :~

The new sulphonylimino-azinylheteroazoles of *he general formula (I) are characterized by strong her-bicidal activity. These compounds represent a chemically novel class of herbicides.
Surprisingly, the new compounds of the formula (I) show considerably better herbicidal action than the structurally similar known herbicide aminotriazole (amitrol).
The invention preferably relates to compounds of the formula (I), in which A represents nitrogen or the grouping C-A1, in which A1 represents hydroqen, fluorine, chlorine, bromine, iodine, cyano or nitro, or represents 1 4 Y 1 C4 alkoxy, C1 C4-alkylthio, Cl-C4-alkylsulphinyl, Cl-C4-alkylsulphonyl, C1-C4-alkylamino or di-(Cl-C4)-alkyl-amino in each case optionally substituted by fluorine and/or chlorine or Cl-C4-alkoxy, or represents phenyl optionally substituted by fluorine, chlorine, bromine, Cl-C4-alkyl, Cl-C2-fluoro- and/or chloro-alkyl, C1-C4-alkoxy and/or C1-C2-fluoro-and/or -chloro-alkoxy, D represents nitrogen or the grouping C-D1, in which D1 represents hydrogen, fluorine, chlorine, ~ bromine, iodine, cyano or nitro, or represents Cl-C4-alkyl, Cl-C4-alkoxy, Cl-C4-alkylthio, Cl-.~.

Surprisingly, some mixtures also show a synergistic action.
Mixtures with other known active compounds, such : as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil ~tructure, are also possible.
The active compounds can be used as auch, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutioNs, suspensions, emulsions, powders, pastes and Le A 26 727 - 44 -201064~
granules. They are used in the cuctomary manner, for example by watering, spraying, atomizing or scattering.
The active compounds according to the invention can be applied either before or after emergence of the plants.
They can also be incorporated into the soil before sowing.
The amount of active compound used can vary within a substantial range. It depends essentially on the nature of the desired effect. In general, the amounts used are between 0.005 and 5 kg of active compound per hectare of soil surface, preferably between 0.01 and 3 kg per ha.
The preparation and use of the active compounds according to the invention can be seen from the following examples.

2.99 g (0.01 mol) of 2-(2-methoxycarbonyl-phenyl-S sulphonylamino)-1,3,4-thiadiazole are dissolved in 100 ml of tetrahydrofuran and 1.12 g (0.01 mol) of potassium tert-butoxide are added at 25C. After stirring for 30 minutes, 2.24 g (0.011 mol) of 2-chloro-4,6-diethoxy-s-triazine are added and the reaction mixture is ~oiled under reflux for 20 hours. The mixture is then concentra-¦~ ted in a water ~et vacuum, the residue is shaken with methylene chloride/water, and the organic phase is separated off, dried using sodium sulphate and filtered.
~ The solvent is distilled off from the filtrate in a water -`~ 15 ~et vacuum, the residue is stirred with diethyl ether and the product obtained crystalline in this way is isolated by filtering with suction.
1.4 g (30% of theory) of 2-(2-methoxycarbonyl-~ phenylsulphonylimino)-3-(4,6-diethoxy-triazin-2-yl)-2,3--~ 20 dihydro-1,3,4-thiadiazole of melting point 97C are obtained.
