Abstract

A pesticide comprising an active ingredient combination consisting of

a) tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione of the formula ##STR1## and b) O-(O-ethyl-S-n-propylphosphoryl)-O-(N-methylcarbamoyl)pyrocatechol of the formula ##STR2## and/or c) O-ethyl S,S-dipropyl phosphorodithioate of the formula ##STR3## and/or d) 2-methyl-2-methylthiopropionaldehyde O-methylcarbamoyloxime of the formula ##STR4## and/or e) N,N-dimethyl-2-methylcarbamoyloximino-2-methylthioacetamide of the formula ##STR5## and/or f) ethyl-4-methylthio-m-tolylisopropylphosphoramide of the formula ##STR6## and/or g) (RS)-S-sec-butyl O-ethyl 2-oxo-1,3-thiazolidin-3-ylphosphono-thioate of the formula ##STR7## and/or h) 2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate of the formula ##STR8## and/or i) S-tert-butylthiomethyl O,O-diethyl phosphorodithioate of the formula ##STR9## and/or j) S,S-di-sec-butyl O-ethyl phosphorodithioate of the formula ##STR10## and/or k) (RS)-O-1-(4-chlorophenyl)pyrazol-4-yl O-ethyl S-propyl phosphorothioate of the formula ##STR11## and its use as a pesticide are described.

Claims

1. A pesticidal composition, comprising

a) tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione of the formula I ##STR23## and at least one further active ingredient selected from the group consisting of

b) O-(O-ethyl-S-n-propylphosphoryl)-O-(N-methylcarbamoyl)-pyrocatechol of the formula II ##STR24## c) O-ethyl S,S-dipropyl phosphorodithioate of the formula III ##STR25## d) (RS)-S-sec-butyl O-ethyl 2-oxo-1,3-thiazolidin-3-yl-phosphonothioate of the formula VII ##STR26## e) S-tert-butylthiomethyl O,O-diethyl phosphorodithioate of the formula IX ##STR27## f) S,S-di-sec-butyl O-ethyl phosphorodithioate of the formula X ##STR28## and g) (RS)-O-1-(4-chlorophenyl)pyrazol-4-yl O-ethyl S-propyl phosphorothioate of the formula XI ##STR29## in a synergistically active amount.

2. The composition defined in claim 1, further comprising customary carriers.

3. The composition defined in claim 1, wherein the further active ingredient is O-(O-ethyl-S-n-propylphosphoryl)-O-(N-methylcarbamoyl)-pyrocatechol of the formula II.

4. The composition defined in claim 3, further comprising customary carriers.

5. The composition defined in claim 4, which contains from 0.1 to 99% by weight of the thiadiazine-2-thione of the formula I and the further active ingredient.

6. The composition defined in claim 3, wherein the weight ratio of the thiadiazine-2-thione of the formula I to the further active ingredient is from 1,000:

1 to 0.1;

1.

7. The composition defined in claim 2, which contains from 0.1 to 99% by weight of the thiadiazine-2-thione of the formula I and the further active ingredient.

8. The composition defined in claim 1, wherein the weight ratio of the thiadiazine-2-thione of the formula I to the further active ingredient is from 1,000:

1 to 0.1;

1.

9. A method of controlling pests, which comprises treating the pests or the areas or spaces to be kept free from pests with a pest-active, synergistically effective amount of the thiadiazine-2-thione of the formula I as defined in claim 1 and the further active ingredient as defined in claim 1.

10. A method of soil disinfection, which comprises treating the soil with an active, synergistically effective amount of the thiadiazine-2-thione of the formula I as defined in claim 1 and the further active ingredient as defined in claim 1.

11. A method of controlling nematodes, harmful soil fungi and soil insects, which comprises treating the ground with an active, synergistically effective amount of the thiadiazine-2-thione of the formula I as defined in claim 1 and the further active ingredient as defined in claim 1.

12. The method of claim 9, wherein the further active ingredient is O-(O-ethyl-S-n-propylphosphoryl)-O-(N-methylcarbamoyl)-pyrocatechol of the formula II.

13. The method of claim 10, wherein the further active ingredient is O-(O-ethyl-S-n-propylphosphoryl)-O-(N-methylcarbamoyl)-pyrocatechol of the formula II.

14. The method of claim 11, wherein the further active ingredient is O-(O-ethyl-S-n-propylphosphoryl)-O-(N-methylcarbamoyl)-pyrocatechol of the formula II.
