Abstract
Description
[0001] A STABLE AGROCHEMICAL COMPOSITION
[0002] FIELD OF THE INVENTION
[0003] The present disclosure relates to an agrochemical composition of a triazolone herbicide and a triketone herbicide. The present disclosure more particularly relates to an agrochemical composition of triazolone herbicide and a triketone herbicide in the form of water dispersible granules.
[0004] BACKGROUND
[0005] Agrochemical formulations are generally formulated as liquid formulations and applied by spraying. To meet the demand for a reduction in the risk to the end user, solid formulations are attractive because the active agrochemical in a solid formulation is immobilised, and solid formulations are of higher density than liquid formulations.
[0006] Granules being solid formulations, are produced to enhance the uniformity of the active ingredient in the final product, to increase the density of the blend so that it occupies less volume per unit weight for better storage and shipment, to facilitate metering or volumetric dispensing, to reduce dust during granulation process, to reduce toxic exposure and process- related hazards, and to improve the appearance of the product. Consequently, the ideal characteristics of granules include narrow particle size distribution for content uniformity and volumetric dispensing, sufficient fines to fill void spaces between granules for better compaction and compression characteristics, and adequate moisture and hardness to prevent breaking.
[0007] Widely acceptable granular formulations, water dispersible granules (WDGs) are wettable powders that have been aggregated into uniform granules size for easier handling and to eliminate respirable particles. They are dispersed in the spray tank and applied as dilute suspensions in the same way as wettable powders. WDGs incorporate the same ingredients as wettable powders, including dispersants and clay, although generally with a higher level of active and less diluent. The granules must be strong enough to resist crumbling into powder, yet readily and completely disintegrate and disperse in the spray tank. This avoids nozzle clogging and ensures the finest particle size of the active ingredient for optimum efficacy.
[0008] Typically, the granules are made by mixing the formulation components including sufficient water to form a paste having suitable rheology for granulation, forming granules from the mixture, and then drying the granules. Several methods are used to prepare WDGs from the starting powder blend. These include pan granulation, fluid bed granulation, spray drying, high speed mixer agglomeration and extrusion granulation. Powder granular formulations can be converted into granules of larger particle size by such processing methods or by adding moderate amount of water to the powder and mixing the powder to agglomerate to form larger granules.
[0009] In extrusion granulation, the formulation will usually be made up as a pasty material that can be readily extruded typically to give spaghetti like strands which are usually subsequently broken up into granules e.g., during drying.
[0010] In fluidized bed granulation, a mixture of the powdered components is fluidized in a fluidized bed and the mixture is sprayed with an aqueous mixture or solution of the liquid components. The particles agglomerate in the bed to form granules which are dried in the bed.
[0011] In pan granulation, the solids are tumbled in a rotating inclined vessel and the liquid components are sprayed on the particles which agglomerate to form granules which are dried either in the vessel or subsequently, for example in a fluidized bed drier. In spray drying, a flowable slurry or a solution of all the components of the formulation is made and passed to a spray drier where the slurry or solution is atomised and dried. If necessary, a desired size range of particles is selected from the spray dried product and / or the product can be agglomerated for example in a fluidized bed, to form a granulate of the desired particle size range.
[0012] Extrusion granulation is generally preferred on the basis of safety, versatility and economy. They are becoming more popular because of their convenience in packaging and use, capable of high active ingredient loading (50 - 90%), being non-dusty, free flowing that disperse quickly when added to water in the spray tank.
[0013] It is also desirable that the water dispersible granule form of the agrochemical formulation to have good dispersibility as well as suspensibility. To obtain desirable dispersibility and suspensibility of WDG formulation upon dilution, choice of surfactants and fillers play a critical role.
[0014] Surfactants play several roles during the preparation of the formulation and condition the final performances of the granules. Their roles include to: (a) help the blending and the extrusion by reducing the friction forces (binding and lubricant effect); (b) provide wettability to the particles of the active ingredient; (c) decreases the interfacial tension between the solid active ingredient (which is mostly hydrophobic) and water; and (d) provide stabilization by giving cohesion to the system.
[0015] Similarly, fillers or inert carriers have a role to adjust the composition and to improve its performances. Such materials may be added as porous carriers, as moisture inhibition agents, to aid binding or agglomeration properties of a formulation or simply to fill a formulation to a convenient weight. Examples of such fillers may include natural silicates such as diatomaceous earth, synthetic precipitated silicas, clays such as kaolin, attapulgites and bentonites, zeolites, titanium dioxide, iron oxides and hydroxides, aluminium oxides and hydroxides, and organic materials such as bagasse, charcoal, and synthetic organic polymers.
[0016] Although attempts have been made in the prior art to prepare triazolone herbicides based granular formulations but there still exists a need for stable granular compositions based on combinations of triazolone herbicides and triketone herbicides with excellent suspensibility and dispersibility.

[0213] Example-1: Amicarbazone 140 g / kg + Sulcotrione 252 g / kg WG
[0214] Table 1
[0215] Amicarbazone, sulcotrione, blend of sodium dodecyl sulfate, sodium decyl sulfate, sodium tetradecyl sulfate, alkyl naphthalene formaldehyde sulfonate, silicone oil based antifoaming agent and kaolin were charged in above mentioned quantities and blended in a vessel for 30- 45 minutes to obtain blend. The blend was further milled. The milled mix was then blended for 40-50 min to obtain homogeneous mixture. The homogeneous mixture along with water was subject to pan granulation in a pan granulator which was set at a specific pan peed and pan angle. The pan granulated granules were passed through sieve to obtain uniformly sized granules. Undersized and oversized granules were separated from the uniformly sized granules and recycled back. The uniformly sized granules were dried to obtain finished granules. Finished granules were packed in a suitable packaging.
