What type of applicator is specifically used for granular formulations to apply chemical evenly?

The drop spreader is specifically designed for applying granular formulations evenly across a target area. This type of applicator has a controlled mechanism that allows for the precise distribution of granules, preventing overlaps and gaps in the application. It features a hopper that holds the granular product and uses a drop mechanism to dispense the material directly onto the ground below, which is essential for achieving uniform coverage.

When using a drop spreader, the applicator can adjust the rate of application based on the setting chosen, which is crucial for ensuring that the correct amount of product is used, thereby minimizing waste and environmental impact. This tool is particularly effective for spreading fertilizers, herbicides, and insecticides that come in granular form, ensuring that they reach the intended areas without excessive spread.

In contrast, hand-held sprayers are typically utilized for liquid applications and are not suitable for granular products. Mechanical injectors are more specialized tools that deliver liquid pesticides directly into the soil or plants, and broadcast spreaders, while also used for granules, generally apply at wider widths, which may not achieve the same level of precision as a drop spreader. Thus, the drop spreader stands out as the most appropriate choice for uniform application of granular formulations.
