What is EC formulations?

What is EC formulations?

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 advantage of an emulsifiable concentrate formulation?

Emulsifiable concentrates have some advantages when compared to other formulations: Low cost of production. Very simple technology. Often better biological activity.

Why do manufacturers mix active and inert ingredients into a formulation?

For these reasons, manufacturers add inert substances, such as clays and solvents, to improve application effectiveness, safety, handling, and storage. Inert ingredients do not possess pesticidal activity and are added to serve as a carrier for the active ingredient.

What is EC in pest control?

ECs are still one of the most common formulation types for crop protection products worldwide. When sprayed, the dilute emulsion gives a uniform and accurate application of active ingredient on the crop, which is essential for effective pest control. …

What is EC in chemistry?

Chemistry. Electrical conductivity of a solution. EC meter (electrical conductivity meter), measures the electrical conductivity in a solution.

Why formulation of pesticides is important?

The purpose of formulating pesticide active ingredients for crop protection is to uniformly spread a small amount of an active chemical over a large area. The goal is to ensure safety in handling and during application and to optimize pesticide efficacy.

What is EC emulsifiable concentrate?

An emulsifiable concentrate (EC) is a liquid formulation that contains technical material, one or more organic water-immiscible solvents and an emulsifier (such as a surfactant). ECs are still one of the most common formulation types for pest control worldwide.

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.

Which is a disadvantage of both EC and ULV formulations?

Which is a disadvantage of both EC and ULV formulations? Solvents may cause rubber or plastic hoses, gaskets, and pump parts and surfaces to deteriorate.

What is the difference between an active ingredient and an inert ingredient?

Pesticide products contain both active ingredients and inert ingredients. Inert ingredients are also called other ingredients. Active ingredients are the chemicals in the product that are actually meant to kill or repel the pest. The other ingredients in the product play some other role besides controlling the pest.

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 does the EC stand for?

European Commission
abbreviation for European Commission: the part of the European Union which is responsible for suggesting laws, making decisions, supporting the Union’s agreements, and general organization: EC ruling/directive.

What makes an EC formulation a EC formulation?

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. ECs are versatile formulations that can be applied with many types of sprayers.

What kind of formulation is an emulsifiable concentrate?

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. what is a flowable formulation?

What kind of solvent is used in EC preparations?

The solvents used in EC preparations are generally petroleum distillates. The typically used solvents include C-9, Aromax, and Solvesso. Due to environmental concern with EC formulation a new trend is being followed in the EC formulations, which involves using biodiesel [30].

What are the different types of pesticide 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:
