What is an advantage of applying herbicide to a lawn in granular form instead of liquid spray?

1. There is little or no drift from the granular form

2. The liquid form is much more expensive

3. The amount of active ingredients needed is greatly reduced with the granular form

4. Most broadleaf weeds have developed resistance to liquid herbicide sprays

The correct answer is: There is little or no drift from the granular form

Applying herbicide in granular form offers the significant advantage of minimal drift. When using a liquid spray, fine droplets can easily be carried away by wind or air currents, leading to unintended application on adjacent areas. This can result in damage to desirable plants and vegetation, as well as reducing the effectiveness of the herbicide on the intended target weeds. Granular herbicides, on the other hand, consist of larger particles that settle closer to the ground and are less susceptible to being blown away, ensuring that the product is applied precisely where it is needed without affecting nearby plants. This effectiveness is particularly important in maintaining a healthy lawn and surrounding landscape. While the other options may contain misconceptions or vary in relevance to the practical use of herbicides, they do not reflect the primary benefit of reducing drift associated with granular applications.
