Which application method refers to uniform pesticide application over an entire area?

Broadcast application refers to the technique of uniformly distributing pesticide over an entire area, such as a field, lawn, or garden, ensuring that every part of the designated space receives the treatment. This method is particularly effective for managing broad-spectrum pests or diseases, where uniform coverage is essential for maximizing efficacy.

In contrast, localized application focuses on specific areas where pests are known to congregate, which may not cover the entire area. Targeted application is more selective, directing the pesticide specifically at identified pests or problem spots rather than across the whole area. Spot application similarly involves treating only specific locations where pests are present, rather than broadcasting over a complete area.

Therefore, the phrase "uniform pesticide application over an entire area" clearly aligns with the broadcast method, making it the correct answer.
