In terms of formulation, what is a potential drawback of liquid herbicides?

Liquid herbicides can indeed be less selective than granular formulations, making this option a valid choice. The reason behind this is that liquid formulations generally mix with water to form a solution, which can lead to broader coverage and potentially affect non-target plants if not applied carefully. While liquid herbicides can effectively control a range of target plants, their ability to distinguish between desirable and undesirable species may be diminished compared to granular formulations, which can be more targeted in their application.

Granular formulations often allow for more precise placement and can be more selective since they are usually applied in a way that minimizes contact with non-target vegetation. This selectivity aspect is crucial in managing specific weed populations while preserving beneficial plants.

The other options present considerations that are not universally applicable. For instance, the cost of liquid herbicides can vary widely based on factors like brand, concentration, and application needs, so they are not always more expensive. Additionally, liquid herbicides are not "always" more effective; efficacy is dependent on numerous factors including the specific herbicide, application method, environmental conditions, and the types of weeds being targeted. Finally, while liquid formulations can require larger volumes for effective coverage due to their dilute nature, this is not inherently a drawback and can vary based on the
