What type of pesticide application covers an entire area uniformly?

Broadcast application is the correct choice because it refers to a method of pesticide application where the entire area is treated uniformly, ensuring even distribution of the pesticide across the targeted space. This type of application is commonly used in situations where there is a need to address widespread pest issues or to prevent infestations over large areas, such as fields, lawns, or gardens.

In broadcast applications, the equipment used (like sprayers or spreaders) is designed to cover a large surface efficiently and consistently. This method allows for thorough coverage, which enhances the effectiveness of the pesticide by reaching more pests in various locations within the treated area.

The other types of applications—spot treatment, localized application, and granular application—focus more on specific areas or targeted spots rather than achieving uniform coverage across a broad area. Spot treatments aim at treating only visible pests or problem areas, while localized applications may focus on a particular section of a property. Granular applications involve dispersing pesticide granules in a specific pattern rather than a uniform spray, which does not address the entire area equally. Thus, broadcast application is specifically designed for even coverage, making it the most appropriate choice for this question.
