Which application method is generally more effective for dense foliage?

The application method that is generally more effective for dense foliage is sprays. When dealing with dense foliage, sprays can easily penetrate through the leaves and branches, allowing for better coverage of the target area. The fine droplets created by sprays can reach the undersides of leaves and the interior of thick plant growth, which is crucial for achieving effective pest control or treatment.

In contrast, dusts and powders may have difficulty adhering to wet or complex surfaces typical in dense foliage, and they might simply settle on the outer surfaces without effectively reaching the pests hidden within. Granules, while useful for soil applications, do not provide the same level of distribution in a foliage-heavy environment and may not effectively contact the pests or plants that require treatment. Therefore, sprays prove to be the superior method in such scenarios.
