In spraying machines used for pest control, the thick cone type nozzle is preferred. This nozzle produces larger droplets that penetrate dense foliage effectively and reduce drift, ensuring better coverage and pest control efficiency.
- Hollow cone nozzles produce finer droplets which are more prone to drift.
- Flat fan nozzles provide a uniform spray but are generally used for herbicides, not insecticides.
Hence, the thick cone nozzle is the most suitable for spraying insecticides.
