What application method uses a wide-angle, flat spray pattern?

The flooding fan nozzle is designed to produce a wide-angle, flat spray pattern. This type of nozzle allows for a more extensive coverage area, which is particularly useful in agricultural and forestry applications where even distribution of pesticide over a broad area is essential. The flooding fan nozzle effectively delivers product by creating a flat spray that minimizes drift and helps in achieving uniformity in application, which is crucial for pest management and ensuring efficacy.

In contrast, other nozzle types may not provide the same wide-angle coverage. For example, a solid stream nozzle is designed to deliver a focused stream of liquid, which is not ideal for wide coverage. The full cone nozzle generally creates a cone-shaped spray pattern, which may not deliver the flat coverage necessary for certain applications. The regular flat fan nozzle does produce a flat spray but might not offer the same wide-angle coverage as the flooding fan nozzle, as it typically has a narrower spray angle. Hence, the flooding fan nozzle is the most suitable choice for applications requiring an expansive, flat spray pattern.
