Pesticides come in different formulations. One of them is Suspension concentrate (SC) formulation with a solid active ingredient dispersed in water. When EC formulations are diluted with water in the spray tank they form a spontaneous emulsion, with emulsion dr Pesticides come in different formulations.
What is the difference between SCSC and EC?
SCs have grown in popularity due to benefits such as absence of dust, ease of use and effectiveness. EC is emulsifiable concentrate ( EC) which is still one of the most common formulation types for crop protection products worldwide.
What is an emulsifiable concentrate (EC)?
An emulsifiable concentrate (EC) is a liquid formulation which contains technical material, one or more organic water-immiscible solvents and an emulsifier (such as a surfactant). When EC formulations are diluted with water in a spray tank they form a spontaneous emulsion.

When EC formulations are diluted with water in the spray tank they form a spontaneous emulsion, with emulsion dr Pesticides come in different formulations. Click to see full answer. Thereof, what is the meaning of EC in insecticide?
What is the difference between ECS and EWS?
In an EW the continuous phase is water (as opposed to an organic solvent for ECs) which offers the benefit of lower phytotoxicity, no flashpoint concern, ease of handling, and a lower environmental impact. EW formulations are physically stabilised by specifically identified polymeric surfactants incorporated at an appropriate level.
What is EC and SC formulation?
Suspension concentrate (SC) formulations consist of having 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 other formulation types such as emulsifiable concentrate (EC) and wettable powder (WP).

What is DF formulation?
Dry flowable (DF) formulations are similar to wettable powders except they are formulated as small granules that produce less dust when measured or mixed as compared to wettable powders. Dry flowable formulations are mixed with liquid materials for ap- plication.
What is a SC pesticide?
Pesticides come in different formulations. One of them is Suspension concentrate (SC) formulation with a solid active ingredient dispersed in water. To formulate a stable SC, the active ingredient must remain insoluble under all temperature conditions. SCs have grown in popularity due to benefits such as absence of dust, ...
What is the difference between insecticide and herbicide?
Herbicide that controls weeds that will take water, nutrients and sunlight away from crops. Insecticide that controls bugs that can cause damage to crops, foods, fiber products, etc. Continue Reading. As Eric says, pesticides are used to control any number of pests.
What is an emulsifier?
Emulsifiable Concentrate (E or EC) EC formulations usually contain an oil-soluble liquid active ingredient, a petroleum-based solvent, and an emulsifier (mixing agent). The emulsifier allows the active ingredient in the solvent to mix with water, these form an emulsion.
What is an emulsion in spraying?
Most suspensions are cloudy or opaque; light cannot pass through them. An emulsion is a mixture of droplets of one liquid in another liquid.
What is the purpose of an emulsifier?
An emulsifier allows the active ingredient and the solvent to mix evenly with water before application. Some agitation may be necessary to keep an emulsion from separating.
Why are inert ingredients included in a formulated product?
The inert ingredients are included in a formulated product to solve these problems. Some inert ingredients pose health risks to pesticide handlers or applicators so their characteristics, along with those of the active ingredient, determine the signal word that appears on the product label. For example:
Do you need an emulsifier for pesticides?
Formulations of these pesticides usually contain the active ingredient, solvent (carrier or diluent), and one or more other ingredients. No emulsifier is required. Solutions are suitable for any type of sprayer and are registered for many sites. Formulation.
What is a formulation in the form of tablets to be used individually?
A formulation in the form of tablets to be used individually, to form a solution of the active ingredient after disintegration in water. The formulation may contain water-insoluble formulants. A formulation consisting of granules to be applied after disintegration and dispersion in water.
What is an emulsifiable granule?
Emulsifiable granules. A granular formulation, which may contain water-insoluble formulants, to be applied as an oil-in-water emulsion of the active constituent (s) after disintegration in water. EP. Emulsifiable powders.
What is a water soluble powder?
Water-soluble powders. A powder formulation to be applied as a true solution of the active constituent after dissolution in water, but which may contain insoluble inert ingredients. SS. Water-soluble powder for seed treatment see note. A powder to be dissolved in water before application to the seed. ST.
What is the material that must consist of a species, subspecies, and strain of bacterium?

Water-miscible formulations
By far the most frequently used products are formulations for mixing with water then applying as sprays. Water miscible, older formulations include:
Other formulations
Other common formulations include granules (GR) and dusts (DP), although for improved safety the latter have been replaced by microgranules (MG e.g. for rice farmers in Japan ). Specialist formulations are available for ultra-low volume spraying, fogging, fumigation, etc. Very occasionally, some pesticides ( e.g.
Products recommended for EW
We recommend the combination of a low and high HLB polymeric surfactant to obtain EW formulations with excellent, long term stability. This surfactant combination ensures that the formulation maintains stability over a range of application temperatures.

Using Pesticide Formulations
Liquid Formulations
- Most liquid formulations are diluted with water to make a finished spray. However, some labels direct users to mix the product with another solvent such as crop oil or other light oil as a carrier. The three main types of liquid formulations are solutions, suspensions, and emulsions: A solutionis made by dissolving a substance in a liquid. A true solution is a mixture that cannot be …
Pesticide Tank Mixtures
- Combining two or more pesticides in a tank mix can be convenient and cost-effective, saving time, labor, fuel, and equipment wear. Combined applications also reduce soil compaction and the risk of mechanical damage to crops or treated areas. Situations appropriate for tank mixing include combining a fungicide and insecticide to treat fruit trees or field crops or to combine two (2) or …
Additives / Adjuvants
- Additives / adjuvants are chemicals that may improve the action of a pesticide OR change the characteristics of a pesticide formulation or a spray mixture. Before using any adjuvant, consult the pesticide product label. Some products have very specific recommendations or prohibitions for adjuvants. If a label instructs you to use an adjuvant, use the type called for at the directed ra…
Summary
- The components of a formulated pesticide include both active and inert ingredients. The active ingredient controls the pest. Inert ingredients include carriers or diluents and adjuvants. The type of formulation may be provided in the identifying information on the front panel of the label. Learn what formulations are available for the pesticide active ingredients you will use.
