Granular applicators have a foliage adhesion disadvantage that includes which of the following?

• A. Granules stick to foliage too well
• B. Granules do not stick to foliage as necessary in certain applications
• C. They never work on soil
• D. They require extensive watering

Answer: (B)

Foliage adhesion is about how well granules stay on leaf surfaces long enough to deliver the active ingredient. When there’s a foliage adhesion disadvantage, the granules do not stick to foliage as necessary in certain applications, so they can be washed off by rain, blown away by wind, or rubbed off by leaf movement. This reduces the amount of pesticide that actually contacts the pests on the leaves and lowers effectiveness. While granular products can work when applied to soil or may require watering to activate in some cases, those factors don’t describe the adhesion problem on foliage. So the issue is that granules do not stick to foliage as necessary in certain applications.
