What is the primary use of full-cone nozzles?

Full-cone nozzles are specifically designed to create a wide and uniform spray pattern, making them ideal for foliar applications. Their design allows for excellent coverage of plant surfaces, ensuring that the pesticide or chemical being applied reaches as much of the foliage as possible. This comprehensive coverage is critical for the effectiveness of many pesticides, as it allows for sufficient contact with pests and diseases residing on the leaves.

While other options mention functions related to different applications, full-cone nozzles shine in their ability to uniformly distribute a spray over a large area, which is essential when targeting the leaves of plants to achieve optimal pest control. This characteristic enhances the likelihood of uniform pesticide coverage and effectiveness in controlling plant-dwelling pests.
