2 Emulsifiable Concentrate. An emulsifiable concentrate consists of an herbicide dissolved in an organic solvent with sufficient emulsifier to create an oil/water emulsion when the concentrate is added to water.
What is emulsifiable concentrate used for?
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 a disadvantage of an emulsifiable concentrate?
The higher concentration of active ingredients in EC formulations is also a hazard to the applicator and other persons if the product is spilled on the skin or consumed. Also, emulsifiable concentrates should never be stored where the liquid can freeze or in areas with excessively high temperatures.
What is an advantage of an emulsifiable concentrate?
Emulsifiable concentrates have some advantages when compared to other formulations: Low cost of production. Very simple technology. Often better biological activity.How does suspension concentrate work?
Due to their various inert ingredients, a suspended concentrate fluid is very thick when sitting still but once you go to shake it or move it, the product turns into a liquid that flows.

When should emulsifiable concentrates be added to the spray tank?
After herbicides are dispersed, increase the carrier to 80 percent of the spray solution to be used. If needed add Liquids and flowables next. Then add emulsifiable concentrates (EC). Microencapsulated formulations should be added after the emulsifiable concentrates.
What does EC mean in insecticide?
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 type of chemical does pest control use?
Pyrethrin & Pyrethroids Pyrethrin and pyrethroids are pesticides used by exterminators. These are active ingredients found in sprays used by experts and only by licensed pest exterminators.

Article first time published onWhat is a flowable pesticide?
A flowable or liquid formulation combines many of the characteristics of emulsifiable concentrates and wettable powders. Manufacturers use these formulations when the active ingredient is a solid that does not dissolve in either water or oil. … Flowable and liquid suspensions settle out in their containers.

Soluble (aqueous) concentrate. (SL) Form true solutions when mixed with water. Easy to mix in the tank. Will not separate or settle out upon standing and requires no agitation once initially mixed.
What is AI in pesticide?
The biological activity of a pesticide, be it chemical or biological in nature, is determined by its active ingredient (AI – also called the active substance). Pesticide products very rarely consist of pure technical material.
What should be done to a spray tank before a tank mix is prepared?
Generally in order to minimize nozzle plugging, the harder-to-mix products should be fully dissolved before the next product is added. The hard-to-mix products are water soluble packets and wettable powders that include dry flowables and water dispersing granules.
When mixing liquid herbicide do you remember?
Dilute herbicide in water (1 part herbicide to 1 to 2 parts water) and agitate before adding to the fertilizer solution. If possible, add the water and herbicide to the tank first, and then add the liquid fertilizer. Maintain continuous, vigorous agitation throughout mixing and application without interruption.
