Definitions

  • the present invention relates to herbicide combinations, stable herbicide compositions and to a method of preparing said herbicide composition.
  • the present invention further relates to a method of controlling weeds.
  • Acetyl CoA carboxylase (ACC’ase) inhibitor herbicides are primarily used for postemergence grass control in broadleaf crops. They are absorbed through foliage and translocated in the phloem to the growing point, where they inhibit meristematic activity.
  • ACC’ase inhibitors include herbicides belonging to aryloxyphenoxypropionate (FOPs), cyclohexanedione (DIMs), and phenylpyrazolin (DENs) chemistries.
  • FOPs aryloxyphenoxypropionate
  • DIMs cyclohexanedione
  • DENs phenylpyrazolin
  • Members of aryloxyphenoxypropionate herbicides act by inhibiting ACC’ase in chloroplasts of sensitive plants.
  • aryloxyphenoxypropionate herbicides are known as fops and are a subgroup of the acetyl-CoA inhibitor group. They control a wide range of annual and perennial grasses in cool and warm temperate regions when applied postemergence but have much less activity when applied to the soil before emergence of the weed. Many of the major fops, including fluazifop, quizalofop, and haloxyfop, are used for grass control.
  • the ACC’ase inhibitors herbicides inhibit ACC’ase, which catalyze the first step in fatty acid synthesis and is important for membrane synthesis. Broadleaf species are naturally resistant to FOPs, DIMs, and DENs herbicides because of a less sensitive ACC’ase enzyme. Natural tolerance of grasses is due to a less sensitive ACC’ase enzyme or a higher rate of metabolic degradation of the ACC’ase inhibitor herbicide.
  • QPE ethyl(R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy] propionate
  • AOPP aryloxyphenoxypropionate
  • QPE is a selective post-emergence herbicide that is registered for use in the control of annual and perennial grass weeds in crops of potatoes, soya bean, sugar beets, peanuts, oilseed rape, sunflowers, vegetables, cotton, flax, and other broad-leafed plants.
  • acetyl CoA carboxylase As a systemic herbicide that inhibits acetyl CoA carboxylase, QPE is absorbed from the leaf surface and translocated throughout the plant via the xylem and phloem, from the treated foliage to the root system, and accumulates in the meristematic tissue, thus inhibiting fatty acid biosynthesis.
  • the acetolactate synthase (ALS) inhibiting herbicides have a broad spectrum of selectivity and are used at low rates as soil-applied or postemergence treatments in many cropping systems, trees and vines, roadsides, range and pasture, turf, and vegetation management.
  • Herbicides which inhibit ALS, belong to the structurally diverse five chemical classes: sulfonylureas, imidazolinones, triazolop yrimidines, pyrimidinylthio(or oxy)- benzoates and sulfonylamino-carbonyltriazolinones.
  • Sulfonylureas are a well-known and important class of herbicides comprising more than 30 active ingredients that are widely used for controlling a range of annual and perennial broadleaved weeds and grasses in a wide variety of agricultural and horticultural crops, as well as in turf, pastures, and non-crop areas.
  • Trifloxysulfuron an acetolactate synthase-inhibitor herbicide can be used to control many broadleaf weeds and nutsedges in cotton production.
  • Trifloxysulfuron sodium salt is a sulfonylurea bro ad- spectrum herbicide, developed for weed control in sugarcane, citrus and cotton.
  • sulfonylurea herbicides including trifloxysulfuron are known to be unstable and tend to hydrolyse via cleavage at the sulfonylurea bridge. While this instability is sometimes considered favourable in terms of achieving low soil residues of these compounds, it poses serious problems commercially with respect to the storage stability of the formulated products. Furthermore, some sulfonylurea herbicides are also prone to degradation due to chemical incompatibilities when other herbicidal ingredients are incorporated in the formulation. This makes the development of liquid formulations that comprise sulfonylurea herbicides and additional herbicidal ingredients even more challenging.
  • quizalofop is observed to be greatly reduced due to its antagonism when used for postemergence control of grasses by the acetolactate synthase inhibitors (sulfonylureas, imidazolinones, pyrimidine thiobenzoates).
  • It is an object of the present invention to provide a herbicide combination comprising an acetyl CoA carboxylase (ACC’ase) inhibitor herbicide and an acetolactate synthase (ALS) inhibitor herbicide such that the combined application of the said herbicides does not result in antagonism between the two herbicides and provides for significant reduction in weed growth.

Description

TITLE: HERBICIDE COMBINATIONS, COMPOSITION AND METHOD FOR
CONTROLLING HARMFUL PLANTS
Technical field
The present invention relates to herbicide combinations, stable herbicide compositions and to a method of preparing said herbicide composition. The present invention further relates to a method of controlling weeds.
Background
Acetyl CoA carboxylase (ACC’ase) inhibitor herbicides are primarily used for postemergence grass control in broadleaf crops. They are absorbed through foliage and translocated in the phloem to the growing point, where they inhibit meristematic activity. ACC’ase inhibitors include herbicides belonging to aryloxyphenoxypropionate (FOPs), cyclohexanedione (DIMs), and phenylpyrazolin (DENs) chemistries. Members of aryloxyphenoxypropionate herbicides act by inhibiting ACC’ase in chloroplasts of sensitive plants. The aryloxyphenoxypropionate herbicides are known as fops and are a subgroup of the acetyl-CoA inhibitor group. They control a wide range of annual and perennial grasses in cool and warm temperate regions when applied postemergence but have much less activity when applied to the soil before emergence of the weed. Many of the major fops, including fluazifop, quizalofop, and haloxyfop, are used for grass control.
The ACC’ase inhibitors herbicides inhibit ACC’ase, which catalyze the first step in fatty acid synthesis and is important for membrane synthesis. Broadleaf species are naturally resistant to FOPs, DIMs, and DENs herbicides because of a less sensitive ACC’ase enzyme. Natural tolerance of grasses is due to a less sensitive ACC’ase enzyme or a higher rate of metabolic degradation of the ACC’ase inhibitor herbicide.
Quizalofop-p-ethyl (QPE; ethyl(R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy] propionate) is a member of the aryloxyphenoxypropionate (AOPP) group of herbicides. QPE is a selective post-emergence herbicide that is registered for use in the control of annual and perennial grass weeds in crops of potatoes, soya bean, sugar beets, peanuts, oilseed rape, sunflowers, vegetables, cotton, flax, and other broad-leafed plants. As a systemic herbicide that inhibits acetyl CoA carboxylase, QPE is absorbed from the leaf surface and translocated throughout the plant via the xylem and phloem, from the treated foliage to the root system, and accumulates in the meristematic tissue, thus inhibiting fatty acid biosynthesis. The acetolactate synthase (ALS) inhibiting herbicides have a broad spectrum of selectivity and are used at low rates as soil-applied or postemergence treatments in many cropping systems, trees and vines, roadsides, range and pasture, turf, and vegetation management. Herbicides, which inhibit ALS, belong to the structurally diverse five chemical classes: sulfonylureas, imidazolinones, triazolop yrimidines, pyrimidinylthio(or oxy)- benzoates and sulfonylamino-carbonyltriazolinones.
Sulfonylureas are a well-known and important class of herbicides comprising more than 30 active ingredients that are widely used for controlling a range of annual and perennial broadleaved weeds and grasses in a wide variety of agricultural and horticultural crops, as well as in turf, pastures, and non-crop areas. Trifloxysulfuron, an acetolactate synthase-inhibitor herbicide can be used to control many broadleaf weeds and nutsedges in cotton production. Trifloxysulfuron sodium salt is a sulfonylurea bro ad- spectrum herbicide, developed for weed control in sugarcane, citrus and cotton. However, sulfonylurea herbicides including trifloxysulfuron are known to be unstable and tend to hydrolyse via cleavage at the sulfonylurea bridge. While this instability is sometimes considered favourable in terms of achieving low soil residues of these compounds, it poses serious problems commercially with respect to the storage stability of the formulated products. Furthermore, some sulfonylurea herbicides are also prone to degradation due to chemical incompatibilities when other herbicidal ingredients are incorporated in the formulation. This makes the development of liquid formulations that comprise sulfonylurea herbicides and additional herbicidal ingredients even more challenging.
The antagonism of graminicides (aryloxyphenoxypropionic acids, cyclohexanediones) used for postemergence control of grasses by the acetolactate synthase inhibitors (sulfonylureas, imidazolinones, pyrimidine thiobenzoates) is well documented by Roger. J. Baerg in Weed Science, 1996. Volume 44:461-468. Combining the two classes of herbicides as a tank mix would provide a broader spectrum of weed control that cannot be obtained with either herbicide alone. However, when these herbicides are mixed, the efficacy of the aryloxyphenoxy propionate herbicide, i.e. quizalofop is observed to be greatly reduced due to its antagonism when used for postemergence control of grasses by the acetolactate synthase inhibitors (sulfonylureas, imidazolinones, pyrimidine thiobenzoates).
Issues relating to antagonism of arylophenoxy propanoates by sulfonyl urea herbicides have been discussed in length by Leslie A. Bjelk and Thomas J. Monaco in Weed Science, Vol. 40, No. 1 (Jan. - Mar., 1992), pp. 1-6. Field trials with chlorimuron and quizalofop applied as a tank mix showed various levels of antagonism toward several annual monocotyledonous weeds with greatest antagonism on broadleaf signal grass. Further studies have showed that absorption and translocation of quizalofop in broadleaf signal grass was reduced by the said sulfonyl urea herbicide.
Research based on illustrating the antagonism between ACC’ase and ALS’s have revealed that tribenuron reduced basipetal movement of diclofop in wild oat (Avena fatua L.). A similar study found that the ALS -inhibiting herbicide pyrithiobac- sodium reduced the translocation of 14C fluazifop-P out of the treated leaf in large crabgrass [Digitaria sanguinalis (L.) Scop.].
Currently, a method to avoid antagonism between ACC’ases (aryloxyphenoxy propionic acids and cyclohexanediones) and ALS’s sulfonylureas is to apply the herbicides separately. However, separate herbicide applications are a less economical means for obtaining broad- spectrum weed control. Another major disadvantage of split application of herbicides is that it typically involves an increase in herbicide used, thus increasing costs.
Therefore, there is a need in the art to provide a stable herbicide composition including aryloxyphenoxy propionic acid herbicide and a sulfonylurea herbicide to obtain a broadspectrum weed control, accompanied by an absence of antagonism.

Issues relating to antagonism of Group 1 herbicides, i.e. acetyl CoA carboxylase inhibitor herbicides and Group 2 herbicides, i.e. acetolactate synthase inhibitor (ALS) herbicides are prevalent and cause considerable issues when applied as a tank-mix and while formulating composition consisting the said ingredients. Various solutions have been proposed to stabilize formulations including an aryloxyphenoxy propionate herbicide such as quizalofop, clodinafop, cyhalofop, fluazifop and haloxyfop and sulfonyl urea herbicides, in particular formulations including quizalofop and trifloxysulfuron. The presence of adjuvant materials, surfactants, and even water, for example, can lead to significant chemical degradation of an aryloxyphenoxy propionate herbicide in an herbicidal composition. Moreover, herbicide antagonism is also observed with reduction in control of certain weeds as a result of applying tank-mixes of herbicide combinations or mixtures of two or more herbicides of an aryloxyphenoxy propionate herbicide and a sulfonyl urea herbicide. For example, a dense emergence of weeds in cotton plantations at the 45th DAA of the treatment consisting of quizalofop-p-tefuryl at a concentration of 25.2g/ha and trifloxysulfuron- sodium at a concentration of 9.9g/ha as represented in Figure 1. This significant weed growth or undesirable vegetation is indicative of the antagonism between the said herbicides at the selected concentration.
The present inventors have found that the combination of an acetyl CoA carboxylase inhibitor (ACC’ase) and an acetolactate synthase inhibitor (ALS), when used at specific application amounts, results in the reduction of antagonism between the herbicides and controls weeds efficiently. More specifically, the present inventors have unexpectedly found that the combination of the aryloxyphenoxy propionate herbicide and the sulfonyl urea herbicide, when both are used at predetermined dosages, results in the reduction of antagonism between the herbicides and yield better control of weeds.
However, there also remains a need to develop a stable herbicidal composition comprising an aryloxyphenoxy propionate herbicide, i.e. quizalofop or salts, esters, isomers, stereoisomers, including mixtures thereof in all ratios, derivatives thereof and a sulfonyl urea herbicide, i.e. trifloxysulfuron, such the rate of degradation of the actives is controlled over an extended period of time and the said herbicides are not antagonistic to each other. The present inventors have provided such a composition to overcome stability issues and the said composition has helped reduce antagonism issues.
