What is the spray angle?

The spray angle refers to the interior angle formed between the outer edges of the spray pattern produced by a nozzle. It is a critical measurement as it determines the width and coverage of the spray when applying pesticides or other liquids. Understanding the spray angle helps applicators effectively target their applications, ensuring that the product reaches the intended area while minimizing overspray and waste.

The correct choice highlights the importance of this angle in achieving optimal application results. By knowing the spray angle, applicators can adjust their distance from the target and the pressure used, affecting how the pesticide is distributed over the area. A wider spray angle may cover more area but can also increase the risk of drift, while a narrower angle focuses the application more precisely but may require more passes to cover larger areas.
