Which nozzle setup is NOT ideal for applying insecticides to dense foliage?

Using an even spray nozzle setup may not be ideal for applying insecticides to dense foliage because it generally delivers a uniform spray pattern that might not penetrate well into thick vegetation. Dense foliage requires more targeted application techniques that can reach into the canopy and effectively cover both upper and lower leaf surfaces where pests may reside.

In contrast, other nozzle types like flooding or cone designs can produce larger droplet sizes or different spray patterns that penetrate the canopy better, ensuring that the insecticide reaches hidden pests effectively. For instance, flooding nozzles create a wide, concentrated flow that can saturate areas quickly, while cone nozzles create an expanding spray that allows for greater coverage and reach into complex plant structures. Thus, for applications in dense foliage, setups that emphasize penetration and coverage are more suitable than a setup that solely focuses on even distribution.
