Which formulation of a pesticide is primarily designed to prevent drift?

The correct answer is the ULV (Ultra Low Volume) formulation. This type of pesticide formulation is specifically designed to minimize the volume of product delivered while maximizing its effectiveness. ULV formulations create very fine droplets, which can help control drift when applied under appropriate conditions.

One key aspect of the ULV formulation is that it optimizes the droplet size, which can enhance adherence to target surfaces while reducing the chances of particles being carried away by wind. This is particularly advantageous in environments where sensitive crops or areas are nearby, as it significantly lowers the risk of non-target exposure through drift.

While other formulations like EC (Emulsifiable Concentrate) and granular formulations serve specific purposes, they do not primarily focus on drift prevention. Microencapsulated formulations can also help in reducing drift to some extent, but ULV formulations are explicitly engineered for this purpose, making them the most effective choice for aiming to prevent pesticide drift during application.
