Description

NOVEL COMBINATIONS OF DEFOLIANTS
FIELD OF THE INVENTION:
The présent invention relates to combinations of défoliants. More specifically, the 5 présent invention relates to synergistic combinations of défoliants for the purpose of eliminating weeds and/or acting as a défoliant and/or a herbicide.
BACKGROUND OF THE INVENTION:
The presence of excessive foliage and weeds at the end of the crops cycle can 10 be a major hindrance during harvesting. Excessive foliage can also mean using more herbicide to clear the way for the next crop. The removal of foliage and some weeds from commercially important crops such as cotton, soybean, legumes, potato etc. is essential for a good harvest. In certain crops, défoliation and no presence of weeds are important specially if hand harvested, since it makes it 15 easier to, for example harvest the fruit, or pick bolls of cotton.
Défoliation is also important for mechanical pickers or harvesters, since the defoliated plants are free from leaves and weeds which could clog spindles of mechanical pickers or add to the trash generated, which must be separated from 20 the desired plant portion being harvested. In addition, défoliation gives a better view to the operator of the mechanical picker allowing better maneuverability to position the picker more easily.
I
Défoliation also prevents the spread of disease in crops such as beans, where the 25 fungal disease on the foliar part .could spread to the beans, thereby decreasing the quality and quantity of harvested produce. Many fungal diseases such as Rust, Bacterial blight, Bean common mosaic virus, Bronzing and sunscald, Alternaria leaf spot, Angular leaf spot, Anthracnose etc. may be controlled in this manner.
) 2
The idéal time to apply a défoliant is when a plant reaches maturity. The main objective is to strip the plant of its leaves, but leave the fruits intact. It is also important that application of the défoliant prevent regrowth of the foliage. Défoliants are generally applied to crop plants when crop is about to reach the 5 harvesting stage.
A good défoliant is one that causes minimal damage to the fruit whilst stripping the foliage away from the plant. A number of compounds, are known to be défoliants, such as pentachlorophenol, sodium chlorate, magnésium chlorate, 10 magnésium chlorate hexahydrate, calcium cyanamide, sodium 3, 6endoxohexahydrophthalate, etc.
Magnésium chlorate is a potent défoliant. It is currently sold as magnésium chlorate hexahydrate and as magnésium chloride-sodium chlorate, which are mixed together 15 in aqueous solution, to form magnésium chlorate hexahydrate.
Very few combinations of Magnésium chlorate are known in the art. CN106259438A (Zhang Xudong) teaches combinations of magnésium chlorate and thidiazuron. However, this combination only teaches use on cotton with limited success and 20 high dosage.
There is therefore a need in the art for combinations that hâve advantageous properties such as a défoliant combinatiorl that is synergistic, helps in défoliation, shows minimal to zéro damage to the fruit, improves yield, reduces dosage of 25 défoliant, thus causing minimal damage to the environment.
Embodiments of the présent invention may therefore ameliorate one or more of the above mentioned problems:
Objects of the invention:
Therefore, one object of the présent invention is to provide a synergistic défoliant combination.
Therefore, one object of the présent invention is to provide a synergistic herbicidal combination.
Another object of the présent invention is to provide a synergistic combination of défoliants that improve yield of the crop.

Another object of the présent invention is to provide a method of controlling weeds at a locus by application of a synergistic herbicidal/defoliant combination.
Another object of the présent invention is to provide a composition comprising a synergistic herbicidal/defoliant combination.
Some or ail these and other objects of the invention can be achieved by way of the invention described hereinafter.

Detailed Description of the invention:
Surprisingly, it has been found by the présent inventors that the combination of spécifie herbicides, with a métal chlorate results in a synergistic défoliation at the locus of the désirable crop plants.
The term herbicide, as used herein, shall mean an active ingrédient that kills, Controls or otherwise adversely modifies the growth of undesirable plants. As used herein, a herbicidally effective or végétation controlling amount is an amount of active ingrédient that causes a “herbicidal effect,” i.e., an adversely modifying effect and includes déviations from natural development, killing, régulation, desiccation, retardation. The terms “plants” and “végétation” include, but are not limited to, germinant seeds, emerging seedlings, plants emerging from végétative propagules, and established végétation. The term “locus” as used herein shall dénoté the vicinity of a desired crop in which weed control, typically sélective weed control is desired. The locus includes the vicinity of desired crop plants wherein the weed infestation has either emerged or is yet to emerge. The term crop shall include a multitude of desired crop plants or an individual crop plant growing at a locus.

In an aspect, the présent invention may provide a synergistic combination of défoliants comprising: .
(a) magnésium chlorate;
(b) a co-herbicide selected from at least one herbicide selected from glutamine synthetase inhibitor herbicides, EPSP synthase inhibitor herbicides, protoporphyrinogen oxidase-inhibiting herbicides, photosystem-ll inhibitor herbicides; and (c) at least one acetyl CoA carboxylase inhibitor herbicide.
Thus, in an embodiment the présent invention may provide synergistic combinations of défoliants comprising:

The présent synergistic défoliant composition of the présent invention exerts an excellent herbicidal effect on weeds at the pre- plant burndown stage. Therefore, for effective exertion of the herbicidal activity, the composition is applied to plots to be planted with useful plants before planting or post-harvest land, fallow fields, ridges, farm roads, water channels, developed pasture land, cemeteries, parks, roads, playgrounds, clear spaces surrounding buildings, reclaimed land, sides of railway tracks, forests, etc. In this case, treatment before the early post-emergence I stage of weeds is the most economically effectile, but the time of treatment is not limited thereto, and it is also possible to control weeds at the growing stage.
j Thus, in an aspect, the présent invention may Drovide a method of controlling weeds and plants in pre plant burndown, said method comprising applying to the locus of the weeds and plants, a synergistic combination comprising a métal chlorate and a co-herbicide selected from glutamine synthetase inhibitor herbicides,
EPSP synthase inhibitor herbicides, protoporphyrinogen oxidase-inhibiting herbicides, photosystem-ll inhibitor herbicides, acetyl CoA carboxylase inhibitor herbicides and mixtures thereof.
in an aspect weeds are selected from ipomoea grandifolia (IAQGR); Cenchrus echinatus (CCHEC); Euphorbia heterophylla (EPHHL), Brachiaria plantaginea (BRAPL), Conyza canadensis (ERICA), Commelina benghalensis (COMBE), and/or Digitaria insularis (DIGIN).
The method of control of the présent invention may be carried out by spraying the suggested tank mixes, or the individual herbicides may be formulated as a kitof-parts containing various components that may be mixed as instructed prior to spraying.
Thus, an embodiment the présent invention may provide a kit of parts comprising a métal chlorate and a co-herbicide in a co-pack that can then be tank mixed before application.
Surprisingly, it has been found by the présent inventors that the métal chlorate and co-herbicides when applied individually, was ineffective in the défoliation, but demonstrated excellent synergistic control when applied together. The combination of a métal chlorate and a co-herbicide synergistically provided effective défoliation at particular locus, without loss of yield. The current invention therefore provides advantLgeous methods of défoliation. The présent methoJ also provides a broader spectrum for défoliants, thus providing a broader spectrum of control at lower use rates.
EXAMPLES:
SYNERGY STUDIES ·
Studies were conducted to compare the desiccation/ défoliation activity of the combination of magnésium chlorate, with herbicides selected from classes of glutamine synthetase inhibitor herbicides, EPSP synthase inhibitor herbicides, protoporphyrinogen oxidase-inhibiting herbicides, photosystem-ll inhibitor herbicides; and acetyl CoA carboxylase inhibitor herbicide and compare its observed efficacy with the “expected” efficacy when magnésium chlorate and coherbicide were applied separately. Any différence between the observed and “expected” efficacy could be attributed to synergy between the two compounds in the défoliation of plants. The expected efficacy of a combination of magnésium chlorate and co-herbicide was calculated using the well-established Colby method.
In the Colby method, the expected (or predicted) response of a combination of herbicides is calculated by taking the product of the observed response for each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of the observed response for each component when applied alone. An unexpected enhancement in efficacy of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed response of each individual component alone. If the observed response of the combination is greater than the expected (or predicted) response, or stated conversely, if the différence between the observed and expected response is greater than zéro, then the combination is said to be synergistic or unexpectedly effective. (Colby,S. R., Weeds, 1967(15), p. 20-22) The Colby method requires only a single dose of each herbicide applied alone and the mixture of both doses. The formula used tp calculate the expected efficacy (EE) which was compared with the observed efficacy (OE) to détermine the efficacy of the présent invention is explained hereinbelow:
EE= (B efficacy +A efficacy- (B efficacy x A efficacy)/100)
The présent inventors hâve adopted the Coby method to calculate synergy of the combination of défoliants. The % défoliation of individual défoliants was calculated and compared to the expected and observed défoliation efficacy.
