Which application method is generally more effective for dense foliage?

Sprays are generally the most effective application method for dense foliage due to their ability to reach and coat the surfaces of leaves and stems. When dealing with dense vegetation, the more targeted application of liquid spray allows for better penetration into the canopy and coverage of all surfaces, including the undersides of leaves where pests often reside.

The liquid form can easily navigate through tight spaces between branches and foliage, ensuring that the active ingredients effectively reach the areas that need treatment. Additionally, sprays can be formulated to have better adherence to plant surfaces and can be adjusted for droplet size, enabling them to cover varying types of foliage effectively.

Other methods, such as dusts or granules, may not provide the same level of coverage or penetration necessary in dense areas. Dusts can drift away and may not settle uniformly on the plant surfaces, while granules typically need to be activated by moisture to release their active ingredients and may not effectively coat the leaves. This makes sprays the superior choice for treating dense foliage.
