Agrochemicals Manufacturer

With constantly growing population the amount of land available for food production is reducing. Consequently there is an increasing pressure to achieve higher yields from the same land. APL is one of the best Agrochemical manufacturer in India & the agrochemical industry focuses on developing active ingredients specifically designed to prevent weeds, fungi, pests and other sources destroying the agricultural yield, while ensuring that crop quality and consistency is maintained. At APL we develop products formulated with speciality additives and adjuvants that improve active delivery and performance. products containing our ingredients are more effective, safer, and more complex. Our Range of speciality Emulsifiers & Adjuvants are offered under the APSURF series for the following formulations :

Types of Pesticides Formulations



Adjuvants are agrochemicals added to crop protection products to enhance the efficacy of active ingredients and improve the overall performance of the product.

APL adjuvants modify the properties of the spray solution, which improves the ability of the active ingredient to target, penetrate or protect the target organism. Adjuvants can be incorporated into a formulation inbuilt or can be added separately into the spray tank along-with other agrochemical products as tank mix application.

Emulsifiable Concentrate (EC)

An emulsifiable concentrate (EC) formulation is a combination of an active ingredient dissolved in a water-immiscible solvent with emulsifiers.

ECs are still one of the most common formulation types for crop protection products worldwide. When EC formulations are diluted with water in the spray tank they form a spontaneous emulsion, with emulsion droplets in the size range of 0.1 to 1.0μm.

The emulsion can be achieved by selecting one or more surfactants based upon their compatibility with the solvent system, including the active ingredient, into water. When sprayed, the dilute emulsion gives a uniform and precise application of active ingredient on the crop, which is essential for effective pest control.

The role of a non-ionic emulsifier is to emulsify the oil when the EC formulation is diluted with water in the spray tank. It improves stability. Non-ionic surfactants are frequently used to balance the polarity requirements of the oil phase.

Suspension Concentrate (SC)

Suspension concentrate (SC) formulations are a solid active ingredient dispersed in water.

SCs have grown in popularity due to benefits such as absence of dust, ease of use and effectiveness when compared to formulation types such as emulsifiable concentrate (EC) and wettable powder (WP) formulations. To formulate a stable SC, the active ingredient must remain insoluble under all temperature conditions.

In SC formulations adjuvants may be incorporated to enhance the bioavailability of the active ingredient, also It is important to include a wetting agent as during the milling process which overcomes high viscosity and excessive thickening as it replaces air and prevents agglomeration, allowing dispersants to perform. Wetting agents can also provide some dispersion. The use of polymeric dispersants is also recommended.

APL Agrochemical manufactures in India has a specific range of emulsifiers for different types of SC formulations.

Flowable Concentrates for Seed Treatment (FS)

Flowable concentrate (FS) formulations are suspensions of solid active ingredients in water which are applied to seeds prior to planting.

FS formulations are a modification of suspension concentrates (SC) with supplemental additives for adhesion to the seed surface and colourants as safety markers to indicate that a seed has been treated with a product.

FS formulations are now the most popular type of seed treatment because they are concentrated formulations and are safer to apply as they are water based.

Micro Emulsions ( ME )

A microemulsion (ME) is defined as a system of oil, water and surfactants that forms a single, optically clear and thermodynamically stable emulsion.

MEs are water based formulations with a very small emulsified droplet size; this makes the formulation transparent.

They are thermodynamically stable over a wide temperature range due to this very fine droplet size, usually between 0.01 and 0.05 μm. Therefore in contrast to other emulsion systems, where the oil droplets can slowly coalesce causing phase separation, in ME formulations this does not occur.

Oil Dispersion (OD)

An oil dispersion (OD) formulation is a solid active ingredient dispersed in oil. Ideally the active ingredient is uniformly suspended in the oil phase.

ODs are an excellent delivery system for water sensitive active ingredients, they exhibit better spray retention, spreading and foliar uptake as the carrier oil often acts as an adjuvant.

Emulsifiers are necessary in order to emulsify the continuous oil phase into water when the OD formulation is diluted prior to being sprayed. Emulsifiers are selected based upon their ability to spontaneously form this emulsion. Their performance is primarily dictated by the nature of the surfactant and their collective effect on how they arrange themselves at the oil/water interface.

Suspoemulsion (SE)

Suspoemulsion (SE) formulations are used to combine two active ingredients with very different physical properties into one formulation. They are a combination of suspension concentrate (SC) and concentrated aqueous emulsion (EW) technologies.

The advantages are that it is possible to formulate multiple active ingredients together, broadening the spectrum of activity and eliminating the disadvantage of tank-mix incompatibility.

Water Dispersible Granule (WDG)

WDGs are a solid, non-dusty granular formulation which disperses or dissolves quickly when added to water in the spray tank to give a fine particle suspension.

They provide a system for delivering solid active ingredients to a target organism. They allow for the production of highly-concentrated formulations which are wettable and easily disintegrated on contact with water. WDGs are an attractive alternative to wettable powder (WP) formulations due to their reduction in dust production.

Wettable Powder (WP)

A WP is a powder formulation that forms a suspension when mixed with water prior to spraying.

WP formulations consist of one or more active ingredients which are blended and mixed with inerts, diluents and surfactants.

Wetting agents are used to facilitate the suspension of the particles in water. A dispersing agent is added to prevent any flocculation of the suspension before it is applied.

Granules ( G )

Granular formulations are similar to dust formulations, except that granular particles are larger & heavier. The active ingredient either coats the outside of the granules or is absorbed into them.

The amount of active content is usually low, ranging from 1 to 15 percent by weight.

Granular pesticides are most often used to apply chemicals to soil to control, weeds, nematodes or insects living in soil. Once applied granules release the active ingredient slowly.

Soluble Powders ( SP / WSP )

Soluble powder formulations look like wettable powders, however with mixed with water these readily dissolve and form a true solution. After they are mixed thoroughly no further agitation is required. The amount of active content in soluble powders ranges from 15 to 95 percent, usually it is more than 50%..
