What are the disadvantages of emulsifiable concentrate solvents?
Emulsifiable concentrate solvents may cause rubber or plastic hoses, gaskets and pump parts to deteriorate. EC’s also are flammable and should be stored in a cool dry area away from open flames. ECs do not perform well on porous surfaces, such as brick and concrete, and are typically less effective against crawling pests.
What is an emulsifier in chemistry?
An emulsion is a mixture of droplets of one liquid in another liquid. Each ingredient keeps its unique properties and identity. In an emulsion, the active ingredient is dissolved in an oil-based solvent. An emulsifier allows the active ingredient and the solvent to mix evenly with water before application.

Why do we use emulsifiable concentrates?
Emulsifiable concentrates work well for this because they make it easier to create an even barrier of insecticide all the way around your home. Emulsifiable concentrate are not necessarily limited to just being insecticides. They are also used in formulations for insect growth regulators such as Gentrol.
What is emulsifiable pest control?
Emulsifiable Concentrates. One of the most powerful and potent types of pest control formulations you can find are emulsifiable concentrat es, also known by their initials EC. Professionals swear by this formulation and use it often when hired to conduct treatments because these chemicals are effective and very versatile. They are also easy to use.
What is EC spray?
ECs are still one of the most common formulation types for pest control worldwide. When EC formulations are diluted with water in a spray tank they form a spontaneous emulsion, with emulsion droplets in the size range of 0.1 to 1.0μm. When diluted in water, it forms either a milky or opaque emulsion for application.
What is sylo insecticide?

What is a concentrated liquid pesticide?
Emulsifiable concentrate is a concentrated liquid formulation of pesticide that needs to be diluted with water to create a spray solution. Emulsifiable concentrates are popular for pest control because they dry clear and often have a long residual effect.
What is diluted water?
When diluted in water, it forms either a milky or opaque emulsion for application . When sprayed, the diluted emulsion gives a uniform and precise application of active ingredient on the target, which is essential for effective pest control.
How to make a sprayer with concentrate?
Fill sprayer halfway with water and then pour concentrate in the correct amount into equipment and dilute it with water according to the label instructions. Finish filling with water and then agitate.
What is the key to a successful emulsifiable concentrate formulation?
The keys to the expeditious, successful development of an Emulsifiable Concentrate (EC) formulation are planning and superb execution. It begins by asking a series of questions; the answers to which should have implications upon the development effort.
Where does ethoxylated surfactant work?
The ethoxylated nonionic surfactants function at the interface between water and the organic solvent. By their chemical composition, one end of the surfactant molecule is soluble in water; and one end is soluble in the organic 'solvent'.
How are surfactants selected?
Surfactants are selected based upon their ability to emulsify the 'solvent' into water. As alluded to above, there are factors that impact emulsion performance: water hardness, dilution rate, time, temperature, and presence of another formulation in the spray tank.
What does "chemically stable" mean?
Chemically Stable = the active ingredient should not chemically degrade during the expected shelf life of the formulation; Physically Stable = the formulation components remain in solution over the expected shelf life of the formulation. Emulsification properties do not deteriorate as the product ages;

Emulsification properties do not deteriorate as the product ages; Emulsification Stable = the active ingredient remains uniformly distributed in the water phase at the application rate using water of variable hardness, over the time frame and under the environmental conditions applied.
Is a formulation an EC?
IMPLICATION : If the formulation components are not in solution, it is not an EC. Since solubility is affected by temperature (usually, the lower the temperature, the poorer the solubility), it is necessary to specify temperature conditions under which the formulation remains in solution.
Is there an infinite number of surfactants?
Although there are an infinite number of 'solvent' compositions which require specific surfactant compositions to form physically stable emulsions, it is not necessary to have available an infinite number of surfactants with which to formulate.
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 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 adjuvants added to pesticides?
Although adjuvants themselves lack any direct pesticidal activity , they are added to pesticide formulations to improve product performance. You should know when and how to use an adjuvant. You must consider several factors when choosing a pesticide formulation. These include.
What is an aerosol?
Aerosol (A) These formulations contain one or more active ingredients and a solvent. Most aerosols contain a low percentage of active ingredient. There are two types of formulations. Ready-to-use (RTU) aerosol formulations are usually small, self-contained units that release pesticide when the nozzle valve is triggered.
How much pesticide can be refilled?
Commercial models, which hold 5 to 10 pounds of pesticide, are usually refillable. Smoke or Fog Generator formulations are used in machines that use a rapidly whirling disk or heated surface to produce and distribute very fine droplets.
What is inert pesticide?
Pesticide formulations are a combination of one or more active ingredients (a.i.), which control pests, and several inert ingredients. Many a.i.s are not soluble in water. Some may be toxic or unsafe to handle. Others may be unstable during storage. 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:

Emulsifiable Concentrate (EC) Formulations
Original SpeedZone herbicides were emulsifiable concentrate (EC) formulations. An EC is an oil-based formulation containing active ingredients that are dissolved in solvents and emulsifiers. It creates an oil-in-water emulsion when added to the spray tank.
Emulsion-in-water (EW) Formulations
SpeedZone ® EW and SpeedZone ® Southern EW are emulsion-in-water (EW) formulations. An EW formulation technology creates a smaller particle size than an EC formulation. The smaller oil droplets result in more active ingredients impacting the leaf surface, which leads to improved efficacy.
Proven Performance
Emulsion-in-water (EW) technology creates a smaller particle size than EC formulations, resulting in less drift ( see charts ), and more active ingredients impacting the leaf surface for improved efficacy compared to EC formulations.
