What type of formulations may require careful management due to their potential to burn foliage?

Microencapsulates
Emulsifiable concentrates
Solutions
Granules

The correct answer is: Emulsifiable concentrates

Emulsifiable concentrates require careful management because they contain active ingredients that can be highly concentrated and may present a risk of phytotoxicity, which can lead to burning or damaging plant foliage. These formulations are oil-based and, when mixed with water, create a stable emulsion. If the concentration is too high, or if they are applied under unfavorable conditions (such as high temperatures or to sensitive plant species), they can adversely affect the plants they are intended to protect. This caution is necessary because the oily nature of emulsifiable concentrates can lead to foliar burn if applied improperly, as they may adhere to leafy surfaces and restrict moisture exchange. Thus, careful dilution and application techniques are essential to mitigate potential damage to plants.
