DESC:FIELD OF INVENTION:
The present invention relates to a ternary herbicidal composition comprising: compound (A) Glufosinate, salts, esters and derivative or L-glufosinate, salts, esters and derivative; compound (B) at least one herbicide selected from class of sulfonylureas; and compound (C) at least one more herbicide is selected from class of nitrophenyl ether, imidazolinone, organophosphorous, dicarboximide, phenoxyacetic, pyridine, cyclohexene oxime, aryloxyphenoxypropionic, triazolone and uracil or combination thereof. The present invention also relates to process for preparing the formulation and its use as herbicide.

BACKGROUND OF THE INVENTION:
These days cultivation of crops and agriculture in general is cost intensive. Receiving a high yield from the cultivated crops is a key. Hence, to achieve higher yield, protecting crops from pests and diseases and weeds is vital. In earlier days man power was utilized to remove weeds. Due to research and development in the field of agriculture now a days chemicals are being used to kill or control the weeds.

It is desirable for the crop protection product to control the harmful plants effectively and, at the same time, to be tolerated by the useful plants in question. Thus selectivity of the crop protection product is essential to selectively kill the unwanted crops and saves the desired crop in the field.

The control of undesired vegetation is extremely important in order to achieve high crop efficiency. In many cases, herbicides have an effect against a spectrum of weeds; however, these herbicides may not be effective on certain type of other weeds, which may also be present in the crop to be protected. Therefore, there is a strong need for mixing two or more herbicides. Hence, the most effective way to control weeds is the application of herbicide in accordance with the appropriate management practices with proper formulation thereof. Treating plants with such a weedicide/herbicide(s) in appropriate formulation helps to control the weeds.

Glufosinate (also known as phosphinothricin and often sold as an ammonium salt) is a naturally occurring broad-spectrum herbicide produced by several species of Streptomyces soil bacteria. Glufosinate is a non-selective, contact herbicide, with some systemic action. Plants may also metabolize bialaphos and phosalacine, other naturally occurring herbicides, directly into glufosinate. The compound irreversibly inhibits glutamine synthetase, an enzyme necessary for the production of glutamine and for ammonia detoxification, giving it antibacterial, antifungal and herbicidal properties. Application of glufosinate to plants leads to reduced glutamine and elevated ammonia levels in tissues, halting photosynthesis and resulting in plant death.

Sulfonylureas are used as herbicides, because they can interfere with plant biosynthesis of certain amino acids. As herbicides sulfonylureas function by interfering with biosynthesis of the amino acids valine, isoleucine, and leucine, specifically via acetolactate synthase inhibition. Compounds in this class include amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, ethametsulfuron-methyl, cinosulfuron, ethoxysulfuron, flazasulfuron, flupyrsulfuron-methyl-sodium, imazosulfuron, metsulfuron-methyl, nicosulfuron,[2] oxasulfuron, primisulfuron-methyl, prosulfuron, pyrazosulfuron-ethyl, rimsulfuron, sulfometuron-methyl, sulfosulfuron, thifensulfuron-methyl, triasulfuron, tribenuron-methyl, and triflusulfuron-methyl. These are broad-spectrum herbicides that kill plants weeds or pests by inhibiting the enzyme acetolactate synthase. In the 1960s, more than 1 kg/ha (0.89 lb/acre) crop protection chemical was typically applied, while sulfonylureates allow as little as 1% as much material to achieve the same effect.

Various kinds of agrochemical formulations are developed based upon active ingredients and scope of application thereof. Herbicides for agriculture purpose are available both in the pure form and as well as incorporated into agrochemical formulations, which typically comprise one or more active ingredients (AIs) and additional excipients substances that enhance the effects and facilitate the application thereof, such as carriers, adjuvants or additives. These formulations can be directly applied after being diluted and the spray mixture formed. The formulation type to be used is primarily defined on the basis of physicochemical characteristics of the AI(s) and can be Capsule suspension (CS), Emulsifiable concentrate (EC), Micro-emulsion (ME), Oil dispersion (OD), Suspension concentrate (SC), Suspo-emulsion (SE), Water dispersible granule (WG or WDG).

Therefore there is further need and scope in the formulation development of comprising one or more active ingredients with better stability profile and increases the synergistic effect of the active ingredients, reduces the toxicity with less introduction of toxic material in environment, which may reduce the dose of the herbicides.

However, there remains a need for a composition that addresses the limitations of current formulations. Such a composition should effectively overcome existing issues while being amenable to straightforward and cost-effective manufacturing processes. This formulation should provide enhanced herbicidal activity through synergistic interactions among its compounds yet be simple to produce without requiring complex or resource-intensive production methods.

Biological Examples:
The synergistic pesticide action of the inventive mixtures can be demonstrated by the experiments below. A synergistic effect exists wherever the action of a combination (ready-mix) or tank mix of active ingredient is greater than the sum of the action of each of the components alone. Therefore, a synergistically effective amount or an effective amount of a synergistic composition or combination is an amount that exhibits greater pesticide activity than the sum of the pesticide activities of the individual components.

In the field of agriculture, it is often understood that the term “synergy” is as defined by Colby S.R. in an article entitled “Calculation of the synergistic and antagonistic responses of herbicide combinations” published in the journal Weeds, 1967, 15, p.20-22, incorporated herein by reference in its entirety. The action expected for a given combination of two or three active components can be calculated as follows:

The objective of the present studies was to study the efficacy, residual control, and synergism under field conditions.
Example 1: Total weed control in non-crop area.
Crop : Fallow land
Target weeds : All weeds (annual and perennial weeds)

Plot size : 10m x 10m= 100 sq.m.
Application time : Full grown weeds.
Application method : foliar spray with backpack sprayer attached flat fan nozzle.
Water volume : 500 liter per hectare
Observation Methods: Weed control (%): weed count recorded at 15, 30 and 45 DAA (Days after Application) by using 0.25 m2 (50 cm x 50 cm) quadrant, treatment wise in minimum five places randomly selected in the plot. The species wise weed count further grouped into Grasses and Broad Leaf weeds (BLW) and sedges. The data presented here as total weed control (grasses + broad leaf + sedges). The average of each variable was used together with the sum of all the variables per plot to calculate the percentage of control.

The field trial results shows the present compositions (T1) provides synergistic and residual control of total weeds up to 45 DAA (days after application). Initial visual observations show speed of kill of weeds was observed faster in with present compositions (T1) as compared with all prior art mixtures (T2 to T4) and solo treatments (T5 to T7). The level of control provided by T1 is much higher than all prior art mixtures (T2 to T4) and solo treatments (T5 to T7) on 45th day. Further the visual observations shows that effective residual control was observed > 60 days by controlling secondary weed flushes.
