The nozzle is the most important component of the sprayer. No matter what type of application you are making, selecting the right nozzle and using it correctly is essential for making a safe and effective pesticide application. The following nozzles were recently introduced and offer improved choices when selecting a nozzle for a weed, insect, or disease problem.

Turbo TeeJet Induction Nozzle

Turbo TeeJet Induction Nozzle The Turbo TeeJet Induction (TTI) nozzle combines air-induction with the pre-orifice and turbulence chamber design of the original Turbo TeeJet nozzle. This combination creates a large droplet spectrum, greatly reducing the risk of drift. It also offers a wider angle spray pattern than TeeJet’s standard Air Induction (AI) nozzle. The TTI is designed to operate between 15 and 100 psi and is currently available in five sizes. It is an excellent choice for applying systemic herbicides where spray drift is a major concern.

CP-65T-S Nozzle

CP-65T-S Nozzle
The CP-65T-S is a flood nozzle designed to meet the needs of post-emergence herbicide applications with a unique design that won it an American Society of Agricultural and Biological Engineers (ASABE) 2005 AE50 Award for design innovation. This design includes quick turn attachment for ease of use with standard nozzle bodies and a compact design offering multiple orifice sizes. To accomplish this, the CP-65T-S has two rotating dials. The first dial has six metering orifices, and is rotated to select the desired orifice size based on the required flow rate for the application. The second dial has three deflectors and is rotated to select the desired deflector based on the required droplet spectrum. A single CP-65T-S is capable of providing flow rates ranging from 0.26 GPM to 1.28 GPM and is designed to operate between 30 and 60 psi.

Hi-flow Nozzle

Hi-flow Nozzle
The Hi-flow nozzle has a wide, 140-degree fan angle and is designed to meet the demand of the high flow rates required when making applications at higher gallons per acre and faster speeds. The Hi-flow nozzle uses a removable pre-orifice to increase spray droplet size and reduce the risk of drift. Hi-flow nozzle tips are available as a single piece, fastcap design for use on standard nozzle bodies. They have a pressure operating range of 15 psi to 80 psi, and are an excellent alternative to standard flood nozzles. Hi-flow nozzles are available in three sizes from Hypro, and 5 sizes from John Deere.
