Which herbicide application equipment is known for having the least drift?

The wick applicator is recognized for having the least drift because it applies herbicide directly to the target plants in a controlled manner. This equipment uses a wicking or contact application method that minimizes the release of herbicide into the air. As a result, it limits the potential for the herbicide to drift away from the intended area, which can occur with spray methods that create a finer mist.

In contrast, hand sprayers, pressurized backpack sprayers, and broadcast spreaders often use a mist or spray application. These methods can generate fine particles that are susceptible to wind and can easily drift beyond the target zone. Because the wick applicator focuses the herbicide application onto the surfaces of the plants, it not only reduces drift but also increases the efficiency of the herbicide by targeting the areas that require treatment directly.
