Ohio Commercial Pesticide Applicator Category 3a – General Aquatic Pest Control Practice Exam

Utilizing hollow cone or flat fan nozzles is essential for aerial application as it maximizes the distribution of the pesticide over the targeted area. These types of nozzles are designed to create a fine spray pattern that helps ensure even coverage on the surface of the water or vegetation. Hollow cone nozzles produce a spray that is effective for targeting specific areas due to their cone-shaped pattern, allowing for better penetration and coverage, especially in dense foliage or aquatic environments.

In aerial applications, achieving uniform coverage is crucial because it minimizes the risk of pesticide runoff and enhances the effectiveness of pest control measures. The correct nozzle type also aids in reducing drift, ensuring that the product reaches its intended target without adversely affecting the surrounding environment.
