Definitions

  • the present invention relates to a combination for the selective control of weeds. More particularly, the present invention relates to a combination of one or more triazinone herbicides with one or more safeners for the selective control of weeds.
  • Some very effective herbicides i.e. herbicides that exhibit highly effective weed control exhibit toxicity on the crop itself along with weeds. In other words, they exhibit non selective control of weeds to be eliminated. This is also the case with Triazinone herbicides such as Amibuzin, Hexazinone, Metamitron, Metribuzin, Isomethiozin, Ipfencarbazone and Ametridione that exhibit excellent weed control but at the cost of damage to crop itself. Sometimes this undesired effect on the crop can be so devastating that whole crop gets wiped out. In such cases, phytotoxicity is said to be 100%. Other instances of unwanted effects of herbicides on crops are lesser plant height or lesser number of plants standing after herbicidal treatments.
  • Triazinone herbicides cover herbicides that act by different modes of action.
  • Ipfencarbazone that acts by inhibiting very long-chain fatty acid (VLCFA) synthesis
  • Amibuzin Hexazinone, Metamitron, Metribuzin, Isomethiozin, and Ametridione that act by inhibiting photosynthesis II are examples of Triazinone herbicides.
  • Photosynthesis II inhibitors act by blocking electron transport and stopping CO2 fixation and production of energy and by causing lipid and protein membrane destruction.
  • VLCFA inhibitors cause preventing of emergence of shoot from the coleoptile or whorl of the grass and cause enlarged cotyledons, restricted growth of the true leaves, dark green color, and stunting of broadleaf plants.
  • IUPAC name of Amibuzin is 6-tert-butyl-3-dimethylamino-4-methyl- 1,2,4- triazin-5(4H)-one.
  • IUPAC name of Hexazinone is 3-cyclohexyl-6-dimethylamino-l-methyl- l,3,5-triazine-2,4(lH,3H)-dione.
  • IUPAC name of Metamitron is 4-amino-4,5-dihydro-3-methyl-6-phenyl- l,2,4-triazin-5-one.
  • IUPAC name of Metribuzin is 4-amino-6-tert-butyl-4,5-dihydro-3- methylthio- 1 ,2,4-triazin-5-one.
  • IUPAC name of Isomethiozin is 6-tert-butyl-4-isobutylideneamino-3- methylthio-l,2,4-triazin-5(4H)-one.
  • IUPAC name of Ipfencarbazone is l-(2,4-dichlorophenyl)-2',4'-difluoro- l,5-dihydro-N-isopropyl-5-oxo-4H-l,2,4-triazole-4-carboxanilide.
  • IUPAC name of Ametridione is l-amino-6-ethylthio-3-neopentyl-l,3,5- triazine-2,4(lH,3H)-dione.

Description

COMBINATIONS OF TRIAZINONE HERBICIDES WITH SAFENERS
Field of the Invention
[0001] The present invention relates to a combination for the selective control of weeds. More particularly, the present invention relates to a combination of one or more triazinone herbicides with one or more safeners for the selective control of weeds.
Background of the Invention
[0002] Some very effective herbicides i.e. herbicides that exhibit highly effective weed control exhibit toxicity on the crop itself along with weeds. In other words, they exhibit non selective control of weeds to be eliminated. This is also the case with Triazinone herbicides such as Amibuzin, Hexazinone, Metamitron, Metribuzin, Isomethiozin, Ipfencarbazone and Ametridione that exhibit excellent weed control but at the cost of damage to crop itself. Sometimes this undesired effect on the crop can be so devastating that whole crop gets wiped out. In such cases, phytotoxicity is said to be 100%. Other instances of unwanted effects of herbicides on crops are lesser plant height or lesser number of plants standing after herbicidal treatments.
[0003] Triazinone herbicides cover herbicides that act by different modes of action. Ipfencarbazone that acts by inhibiting very long-chain fatty acid (VLCFA) synthesis, Amibuzin, Hexazinone, Metamitron, Metribuzin, Isomethiozin, and Ametridione that act by inhibiting photosynthesis II are examples of Triazinone herbicides. Photosynthesis II inhibitors act by blocking electron transport and stopping CO2 fixation and production of energy and by causing lipid and protein membrane destruction. VLCFA inhibitors cause preventing of emergence of shoot from the coleoptile or whorl of the grass and cause enlarged cotyledons, restricted growth of the true leaves, dark green color, and stunting of broadleaf plants.
[0004] IUPAC name of Amibuzin is 6-tert-butyl-3-dimethylamino-4-methyl- 1,2,4- triazin-5(4H)-one.
[0005] IUPAC name of Hexazinone is 3-cyclohexyl-6-dimethylamino-l-methyl- l,3,5-triazine-2,4(lH,3H)-dione. [0006] IUPAC name of Metamitron is 4-amino-4,5-dihydro-3-methyl-6-phenyl- l,2,4-triazin-5-one.
[0007] IUPAC name of Metribuzin is 4-amino-6-tert-butyl-4,5-dihydro-3- methylthio- 1 ,2,4-triazin-5-one.
[0008] IUPAC name of Isomethiozin is 6-tert-butyl-4-isobutylideneamino-3- methylthio-l,2,4-triazin-5(4H)-one.
[0009] IUPAC name of Ipfencarbazone is l-(2,4-dichlorophenyl)-2',4'-difluoro- l,5-dihydro-N-isopropyl-5-oxo-4H-l,2,4-triazole-4-carboxanilide.
[0010] IUPAC name of Ametridione is l-amino-6-ethylthio-3-neopentyl-l,3,5- triazine-2,4(lH,3H)-dione.
[0011] Chemical agents called as safeners, when used with herbicides, act as their antidotes and make use of the herbicides safer. However, it is pertinent to note that not all the safeners work well with all the herbicides. Scientists are always faced with the challenge of finding safener herbicide combinations that work well.
[0012] There is therefore a need in the art for safener combinations with triazinone herbicides that reduce their phyto toxicity, result in increased plant height and/or increased number of plants standing after herbicidal treatment.

Detailed description of invention
[0031] As used herein, the term "control" includes controlling a pest, i.e. killing, also protecting a plant, or seed from attack or invasion by said pest.
[0032] It has surprisingly been found by the present inventors that combination of one or more triazinone herbicides with one or more safeners selectively controls weeds. Selective weed control was also accompanied by increased plant growth and increased number of plants standing after treatments. Treatments with one or more triazinone herbicides alone resulted in phyto toxicity, lesser plant height and lesser number of plants standing after treatments. Selective weed control, increased plant growth and increased number of plants stranding after treatments with combination of one or more triazinone herbicides with one or more safeners were unexpected.
