Agribusiness: New spray nozzles for Asian rust

Feb 23, 2005 9:06 AM

Turbo TeeJet Duo and DG TwinJet spray nozzles, designed to provide thorough plant coverage for effective treatment of Asian soybean rust, are the latest additions to the TeeJet line of spray products.

Featuring a dual flat spray pattern, the Turbo TeeJet Duo provides better canopy penetration and coverage than single flat spray nozzles and produces larger droplets than other dual spray nozzles for greater drift control, according to TeeJet.

The TT Duo is versatile. The operating pressure range is 15 to 90 psi (1.03 to 6.21 bar) and a 60-, 90- or 120-degree included angle between spray patterns can be used, depending on tip configuration. The TT Duo is available in a variety of capacities. The QJ90 adapter cap used in the TT Duo can also be equipped with other standard TeeJet spray tips such as the XR TeeJet.

The DG TwinJet provides good leaf coverage and canopy penetration. The nozzle uses a pre-orifice in conjunction with a dual orifice to create two identical flat spray patterns with a 60-degree included spray angle between them. The nozzle produces finer droplets than the TT Duo but larger droplets than standard twin-spray nozzles to help minimize drift. DG TwinJet nozzles have an operating pressure range of 30 to 60 psi (2.07 to 4.14 bar).

“With yield loss potential of 10 percent to 90 percent from ASR, we are doing everything we can to help educate nozzle users about proper nozzle selection and application techniques. Introducing two new nozzles that offer excellent coverage is a part of this effort,” said Marty Heyen, marketing and customer relations manager for TeeJet Spray Products.

“Selecting the right spray nozzle is the least expensive thing users can do to protect their crops and investments,” said Heyen.

Spraying Systems Co., is located in Wheaton, Ill.
