Abstract

The present invention primarily relates to the use of specific herbicide combinations based on iodosulfuron or of a composition comprising said specific herbicide combinations for controlling harmful plants in teff (Eragrostis tef) plants. The present invention also relates to the use of specific herbicide combinations based on iodosulfuron or of a composition comprising said specific herbicide combinations as plant growth regulators for teff (Eragrostis tef) plants. Furthermore, the present invention relates to a corresponding method of controlling harmful plants in teff (Eragrostis tef) plants and to a corresponding method of regulating plant growth of teff (Eragrostis tef) plants.

First claim

The invention claimed is:

1. A method for controlling harmful plants in teff ( Eragrostis tef ) plants, and/or regulating plant growth in teff ( Eragrostis tef ) plants,
comprising applying a combination of (i) iodosulfuron, its esters and/or salts thereof, (ii) a second herbicide, and (iii) mefenpyr or its diethyl ester
onto the teff ( Eragrostis tef ) plants, seeds of the-teff ( Eragrostis tef ) plants, and/or the area where the teff ( Eragrostis tef ) plants grow,
wherein the second herbicide (ii) is selected from the group consisting of (ii-a) amidosulfuron, wherein the weight ratio of the total amount of constituent (ii-a) to the total amount of constituent (i) is 3:1 to 6:1, (ii-b) 2,4-D, its esters and/or salts thereof, wherein the weight ratio of the total amount of constituent (ii-b) to the total amount of constituent (i) is 15:1 to 40:1, (ii-c) mesosulfuron, its esters and/or salts thereof, wherein the weight ratio of the total amount of constituent (ii-c) to the total amount of constituent (i) is 3:1 to 8:1, and (ii-d) fenoxaprop, its esters and/or salts thereof, wherein the weight ratio of the total amount of constituent (ii-d) to the total amount of constituent (i) is 5:1 to 12:1; and
wherein the total amount of constituent (iii) to the total amount of constituent (i) is 2.5:1 to 20:1.

2. A method according to claim 1 , wherein constituent (i) comprises iodosulfuron-methyl and/or iodosulfuron-methyl-sodium.

3. A method according to claim 1 , wherein constituent (ii) is (ii-b) 2,4-D, its esters and/or salts thereof, and/or (ii-d) fenoxaprop, its esters and/or salts thereof.

4. A method according to claim 1 , wherein said combination comprises
(i) iodosulfuron-methyl and/or iodosulfuron-methyl-sodium,
one or more constituents (ii) selected from the group consisting of constituent (ii-b) 2,4-D-sodium, 2,4-D-ammonium salts, 2,4-D-C 2 -C 8 alkyl esters, constituent (ii-d) fenoxaprop-ethyl and fenoxaprop-P-ethyl
and
(iii) mefenpyr-diethyl.

5. A method according to claim 4 , wherein the combination does not include any other herbicides or safeners besides those recited.

6. A method according to claim 1 , wherein said combination comprises
(i) iodosulfuron-methyl and/or iodosulfuron-methyl-sodium,
one or more constituents (ii) selected from the group consisting of constituent (ii-b) 2,4-D-C 2 -C 8 alkyl esters, constituent (ii-d) fenoxaprop-ethyl, and fenoxaprop-P-ethyl,
and
(iii) mefenpyr-diethyl.

7. A method according to claim 6 , wherein the combination does not include any other herbicides or safeners besides those recited.

8. A method according to claim 1 , wherein the combination additionally comprises one or more further components selected from the group consisting of formulation auxiliaries, additives customary in crop protection, and further agrochemically active compounds.

9. A method according to claim 1 , wherein one, several or all harmful plants are controlled and are selected from the group consisting of Amaranthus spp., Argemone spp., Avena spp., Bidens spp., Bromus spp., Chenopodium spp., Chrysanthemum spp., Commelina spp., Convolvulus spp., Cyperus spp., Digitaria spp., Echinochloa spp., Eleusine spp., Eragrostis spp., Erucastrum spp., Euphorbia spp., Foenicum spp., Galinsoga spp., Guizotia spp., Leucas spp., Lolium spp., Nicandra spp., Oxygonum spp., Parthenium spp., Phalaris spp., Plantago spp., Portulaca spp., Raphanus spp., Setaria spp., Snowdenia spp., Solanum spp., Sorghum spp. and Xanthium spp.

10. A method according to claim 1 , wherein one, several or all harmful plants are controlled and are selected from the group consisting of Amaranthus hybridus, Amaranthus retroflexus, Amaranthus palmeri, Argemone ochroleuca, Avena fatua, Bidens pachyloma, Bidens pilosa, Bromus pectinatus, Chenopodium album, Chrysanthemum segetum, Commelina benghalensis, Convolvulus arvensis, Cyperus esculentus, Cyperus rotundus, Digitaria abyssinica, Echinochloa crus - galli, Eleusine indica, Eragrostis aspera, Erucastrum arabicum, Euphorbia schimperiana, Foenicum vulgare, Galinsoga parviflora, Guizotia scabra, Leucas martinicensis, Lolium temulentum, Nicandra physalodes, Oxygonum sinuatum, Parthenium hysterophorus, Phalaris paradoxa, Plantago lanceolata, Portulaca oleracea, Raphanus raphanistrum, Setaria pallidefusca, Setaria pumila, Setaria verticillata, Setaria viridis, Snowdenia polystachya, Solanum physalifolium, Sorghum arundinaceum and Xanthium strumarium.

11. The method according to claim 1 , wherein one, several, or all harmful plants are controlled.

12. The method according to claim 1 , wherein the teff ( Eragrostis tef ) plants are red teff ( Eragrostis tef ) plants or white teff ( Eragrostis tef ) plants.

13. The method according to claim 1 , wherein said combination is applied post-emergence to the harmful plants.

14. A method according to claim 1 , wherein harmful plants are controlled by treating the teff plants.

15. A method according to claim 1 , wherein the plant growth of the teff plants is regulated.

16. A method according to claim 1 , wherein the herbicides in the combination consist of) (i) iodosulfuron, its esters and/or salts thereof and one or more of (ii-a) amidosulfuron, (ii-b) 2,4-D, its esters and/or salts thereof, (ii-c) mesosulfuron, its esters and/or salts thereof, and/or (ii-d) fenoxaprop, its esters and/or salts thereof.
