What is a notable disadvantage of granule and pellet formulations?

1. Uniform application is hard to achieve

2. Requires no measurement

3. Easy to apply and store

4. Effective on most pest problems

The correct answer is: Uniform application is hard to achieve

Granule and pellet formulations often present challenges in achieving a uniform application. This is a significant disadvantage because uneven distribution can lead to inconsistent pest control and even damage to non-target plants or wildlife. When granules are applied, factors such as wind, moisture, and the physical characteristics of the granules themselves can impact how evenly they spread. A more concentrated area may result in excessive application, leading to potential toxicity issues, while sparse areas may not effectively control pest populations. While the other aspects mentioned, such as ease of measurement, storage, and general effectiveness might seem beneficial, they do not address the critical need for uniform distribution across the treatment area. In pest management, achieving consistent application is essential for ensuring that the product performs as intended and minimizes negative environmental impacts.
