Which formulation type contains a low percentage of active ingredient and is often used in ready-to-use products?

1. Flowables

2. Aerosols

3. Emulsifiable Concentrates

4. Solutions

The correct answer is: Aerosols

The formulation type that contains a low percentage of active ingredient and is often utilized in ready-to-use products is aerosols. Aerosol formulations are designed to deliver pesticides in a convenient spray format, which allows for easy application and immediate use without the need for further mixing or dilution. This characteristic makes them particularly appealing for consumers who may not have the expertise or equipment to prepare more concentrated formulations. These formulations typically include propellants along with the active ingredient, which facilitates the dispersal of the pesticide in a fine mist. This ensures an even application over a target area. Additionally, the low concentration of active ingredients in many aerosol products helps to limit potential risks associated with higher concentrations, making them suitable for home use where safety is a primary concern. In contrast, flowables, emulsifiable concentrates, and solutions usually contain higher concentrations of active ingredients and often require careful mixing or dilution before application, making them less convenient for direct consumer use.
