What is the common application method for granular herbicides?

Granular herbicides are designed to be applied in a dry form directly to the target area. The common method of applying these herbicides is through hand application or using granule spreaders. Hand application is often suitable for small areas where precision is needed, allowing the applicator to control the distribution of the granules. For larger areas, granule spreaders provide an efficient means to ensure an even distribution of the herbicide across the treatment site.

This method of application is effective because it allows the granular herbicide to settle on the surface of the vegetation or soil, where it can then dissolve in moisture and be absorbed by the target plants, ultimately providing effective control of unwanted vegetation. The other methods listed, such as spraying with a spray bottle or injecting into the water, do not align with the intended use and functionality of granular herbicides, which are specifically formulated to be spread in a dry form. Similarly, saturating water with liquid herbicide pertains to different types of herbicide formulations and application scenarios.
