Flat-fan nozzles are primarily used for which type of application?

Flat-fan nozzles are designed to produce a medium droplet size and create a fan-shaped spray pattern, making them particularly suitable for foliar applications. This type of nozzle allows for even coverage of leaves and can effectively spread fertilizers or pesticides over the foliage to enhance absorption by plants. The medium droplet size strikes a balance, reducing the risk of drift while ensuring adequate coverage is achieved on the target surfaces.

In contrast, root zone placement typically requires nozzles that deliver the product directly to the soil, rather than over the foliage, which is not the primary function of flat-fan nozzles. Large droplet systems are more focused on delivering heavier droplets for quick coverage, which is not the primary application setting for flat-fan nozzles either. Drip irrigation systems function through a completely different mechanism, directing water and nutrients through tubes to the roots, thus further differentiating them from the capabilities of flat-fan nozzles.
