Technical Field

The present invention relates to combinations of defoliants. More particularly, the present invention relates to synergistic combinations of defoliants to eliminate weeds and/or act as defoliants and/or herbicides.

Background

Excessive foliage and weeds at the end of the crop cycle may be a major obstacle during harvesting. Too many leaves may also mean that more herbicide needs to be used to clear the way for the next crop. The removal of leaves and some weeds from commercially important crops such as cotton, soybeans, beans, potatoes, etc. is essential for good harvest. In certain crops, defoliation and the absence of weeds are particularly important, especially in manual harvesting, as this can make it easier to harvest the fruit, or pick cotton, for example.

Defoliation is also important for mechanical pickers or harvesters because the defoliated plants are free of leaves and weeds that can clog the mandrel of the mechanical picker or add to the waste produced which must be separated from the desired plant parts to be harvested. Furthermore, the defoliation provides a better view for the operator of the mechanical picking machine, and thus a better manoeuvrability, allowing the picking machine to be placed more easily.

Defoliation also prevents the spread of disease in crops such as kidney beans, where fungal disease on the leaf portion can spread to the bean, thereby reducing the quality and quantity of the harvested product. Many fungal diseases such as Rust (Rust), bacterial leaf blight (bacillalbight), Bean common mosaic virus (Bean common mosaic virus), Bronzing and sunscald (sunscald), leaf spot (Alternaria leaf spot), Angular leaf spot (Angular leaf spot), Anthracnose (Anthracnose), and the like can be controlled in this manner.

The ideal time for applying the defoliant is when the plant reaches maturity. The main purpose is to peel off the leaves of the plant, but leave the fruit intact. It is also important to apply defoliants to prevent regrowth of the leaves. Defoliants are typically applied to crop plants when the crop is about to reach the harvest stage.

A good defoliant is one that causes minimal damage to the fruit while the leaves are stripped from the plant. Many compounds are known as defoliants, such as pentachlorophenol (pentachlorophenol), sodium chlorate, magnesium chlorate hexahydrate, calcium cyanamide (calcium cyanamide), sodium 3, 6-endohexahydrophthalate (sodium 3, 6-endohexahydrophthalate), and the like.

Magnesium chlorate is an effective defoliant. Currently sold as magnesium chlorate hexahydrate and magnesium chloride-sodium chlorate, are mixed together in an aqueous solution to form magnesium chlorate hexahydrate.

Very few combinations of magnesium chlorate are known in the art. CN 106259438A (zhang asahi east) teaches a combination of magnesium chlorate and thidiazuron. However, this combination is only taught for use on cotton with limited success and high use rates.

Thus, there is a need in the art for combinations of defoliants that have advantageous properties, such as synergistic effects, aid in defoliant, exhibit minimal to zero damage to the fruit, increase yield, reduce defoliant usage, and thereby cause minimal damage to the environment.

Accordingly, embodiments of the present invention may ameliorate one or more of the above problems:

objects of the invention

It is therefore an object of the present invention to provide synergistic defoliant combinations.

It is therefore an object of the present invention to provide a synergistic herbicidal combination.

It is another object of the present invention to provide a synergistic combination of defoliants that increases crop yield.

It is another object of the present invention to provide a method for increasing crop yield by applying a synergistic combination of defoliant combinations.

Detailed Description

Surprisingly, the present inventors have found that the combination of a specific herbicide with a metal chlorate results in synergistic defoliation at the locus of the desired crop plant.

As used herein, the term herbicide shall refer to an active ingredient that kills, controls, or otherwise adversely alters the growth of undesirable plants. As used herein, an herbicidally effective or vegetation controlling amount is an amount of active ingredient that causes a "herbicidal effect," i.e., an adversely altering effect and includes deviations from natural development, killing, regulation, desiccation, retardation. The terms "plant" and "vegetation" include, but are not limited to, germinating seeds, germinating seedlings, plants germinating from vegetative propagules and established vegetation. The term "locus" as used herein shall mean the vicinity of a desired crop where weed control, typically selective weed control, is desired. The locus includes the vicinity of the desired crop plant where weed infestation has or has not occurred. The term crop shall include a large number of desired crop plants or individual crop plants grown at a certain locus. The term "defoliant" shall mean a compound that when applied at the site of a plant, causes only the leaves of the plant to shed or fall off.

Typically, the metal chlorate and the co-herbicide may be applied at levels sufficient to defoliate the plant or inhibit regrowth of the plant. In one embodiment, the weight ratio of the amount of metal chlorate applied to the plant to the amount of co-herbicide applied to the plant is from about 1: 200 to about 200: 1. In one embodiment, the weight ratio is from about 1: 80 to about 80: 1, preferably from about 1 to about 50: 0.05 to about 50. In another embodiment, the weight ratio is from about 1 to about 10: 0.05 to about 10, preferably from about 1 to about 5: 0.05 to about 5.

In one embodiment, the metal chlorate is applied at a rate of from about 0.03 to about 0.5, preferably from about 0.06 to about 0.25 pounds per acre (lb/acre). The application rate of the combination herbicide is from about 0.005 to about 10 pounds/acre, from about 0.005 to about 5 pounds/acre, from about 0.01 to about 5 pounds/acre, or from about 0.01 to about 1 pound/acre.

The application time of the synergistic defoliant composition of the present invention may vary to some extent with weather conditions and the growth conditions of the crop, but is typically the time at which vegetative growth of the crop plants to be treated is complete and the maturation period is about to begin. This time may vary from crop to crop.

In one aspect, the present invention may provide a synergistic combination of defoliants comprising:

(a) magnesium chlorate;

(b) a co-herbicide selected from at least one herbicide selected from the group consisting of glutamine synthetase inhibitor herbicides, EPSP synthetase inhibitor herbicides, protoporphyrinogen oxidase inhibitor herbicides, photosystem II inhibitor herbicides; and

(c) at least one acetyl-coa carboxylase inhibitor herbicide.

Thus, in one embodiment, the present invention may provide a synergistic combination of defoliants comprising:

(a) magnesium chlorate;

(b) a co-herbicide selected from at least one herbicide selected from the group consisting of glutamine synthetase inhibitor herbicides, EPSP synthetase inhibitor herbicides, protoporphyrinogen oxidase inhibitor herbicides, photosystem II inhibitor herbicides; and

(c) haloxyfop-methyl.

In one embodiment, the combined component defoliants of the present invention may be prepared by mixing magnesium chlorate, the co-herbicide and the acetyl-CoA carboxylase inhibitor herbicide in the ratio of (1-80) to (1-80), respectively.

In one aspect, the present invention may provide a method of drying/defoliating a plant in proximity to harvest comprising applying to the locus of the plant a synergistic combination comprising a metal chlorate and at least one co-herbicide.

In one aspect, the invention may provide a method of desiccating/defoliating a plant in proximity to harvest comprising applying to the locus of the plant a synergistic combination comprising magnesium chlorate and a co-herbicide selected from the group consisting of glutamine synthetase inhibitor herbicides, EPSP synthetase inhibitor herbicides, protoporphyrinogen oxidase inhibitor herbicides, photosystem II inhibitor herbicides, acetyl-coa carboxylase inhibitor herbicides and mixtures thereof.

The synergistic defoliant composition of the present invention exerts an excellent herbicidal effect on weeds at the pre-burn stage of plants. Therefore, in order to effectively exert herbicidal activity, the composition is applied to a land mass on which useful plants are to be planted, on a land before or after planting, a fallow land, a ridge land, a farm road, a ditch, a developed pasture, a graveyard, a park, a road, a playground, an open space around a building, a reclaimed land, both sides of a railway, a forest and the like. In this case, the treatment before the initial stage after emergence of the weeds is most economically effective, but the treatment time is not limited thereto, and the weeds can also be controlled at the growth stage.

Thus, in one aspect, the invention may provide a method of controlling weeds and plants prior to burn off of the plants, the method comprising applying to the locus of the weeds and plants a synergistic combination comprising a synergistic combination of a metal chlorate and a co-herbicide selected from the group consisting of glutamine synthetase inhibitor herbicides, EPSP synthetase inhibitor herbicides, protoporphyrinogen oxidase enzyme inhibitor herbicides, photosystem II inhibitor herbicides, acetyl-coa carboxylase inhibitor herbicides and mixtures thereof.

In one aspect, the weeds are selected from sweet potatoes (Ipomoea grandifolia, IAQGR); tribulus terrestris (Cenchrus echinatus, CCHEC); scarlet caterpiller fungus (EPHHL), Plantago asiatica (BRACHIARIA PLANTINEA, BRAPL), Conyza canadensis (ERICA), Dicladium amabilis (COMBE), and/or Gymnema sylvestre (DIGIN).

The control method of the present invention can be carried out by spraying the suggested tank mix, or individual herbicides can be formulated into a kit of parts containing the respective components that can be mixed as instructed prior to spraying.

Thus, one embodiment of the present invention may provide a kit of parts comprising metal chlorate and a co-herbicide in a co-package, which kit of parts may then be tank mixed prior to application.

Surprisingly, the present inventors have found that metal chlorate and co-herbicides are not effective in defoliation when applied alone, but show excellent synergistic control when applied together. The combination of metal chlorate and co-herbicide synergistically provides effective defoliation at a particular locus without yield loss. Thus, the present invention provides an advantageous method of defoliation. The present method also provides a wider range for the defoliant, and thus a wider range of control at lower rates of use.
