Granular herbicides should be applied in what manner?

Granular herbicides are typically best applied using a broadcast spreader. This method ensures an even distribution of the granules over a large area, which is essential for effective weed control. A broadcast spreader allows for the controlled release of the product, maximizing its efficacy and minimizing environmental impact by avoiding over-application in certain spots.

Applying granular herbicides by hand can lead to uneven coverage, which may result in inadequate weed control and potential harm to desirable plants. While handheld application might be practical in very small areas or for spot treatments, it lacks the precision and efficiency of using a spreader.

Using a spraying mechanism is not suitable for granular products since they are designed for application in a solid form rather than as a liquid. Automated drone technology, although innovative, is generally not employed for granular herbicides due to the challenges of ensuring proper distribution and the potential for granules to become clogged in the delivery system. Thus, the most effective and recommended approach for applying granular herbicides is with a broadcast spreader.
