What is a unique challenge related to the use of granular applications (G)?

A unique challenge related to the use of granular applications is that these products require moisture to effectively release their active ingredients. Granular formulations typically consist of solid particles that need water to dissolve or become mobilized in the soil. Without sufficient moisture, whether from rainfall or irrigation, the active ingredient may remain inactive, limiting its effectiveness in controlling pests or diseases.

This requirement for moisture is particularly critical in regions or seasons where the precipitation is low, potentially leading to situations where the granules are applied but do not provide the desired pest control because they are not activated. Understanding this aspect helps applicators plan their treatments more effectively, ensuring that environmental conditions will enable the granules to work as intended.

The other options address challenges that are less specific to the nature of granular applications compared to the reliance on moisture for activation.
