Which formulation type typically has solvents that can damage rubber or plastic parts?

Emulsifiable Concentrates (EC) are designed to dissolve in water to form an emulsion, typically consisting of active ingredients dissolved in organic solvents. These solvents play a key role in the product's effectiveness as they can enhance the penetration and applicability of the pesticide on targeted pests.

However, many of these organic solvents can be quite aggressive, leading to the possibility of damaging rubber or plastic components in equipment, such as seals and hoses. This characteristic makes handling and storing emulsifiable concentrates more critical; special care should be taken to avoid contact with materials that can be compromised by the solvents.

In contrast, granular formulations and palletized formulations do not contain organic solvents and are typically solid, reducing the risk of solvent-related damage to equipment. Water-soluble powders are also less likely to cause harm, as they dissolve in water without the presence of harmful solvents. This distinction is crucial for maintaining the integrity of application equipment while ensuring the effective use of pesticides.
