The design, developed by Syngenta's own specialists, increases spray energy and velocity to better penetrate the crop's foliage canopy.
The company's vegetable field technical manager Ian Holmes said: "Growers can achieve better spray coverage and retention in the mid and lower canopy from the high energy of the nozzle, along with comparatively lower water volumes for greater sprayer output per day."
The nozzles also provide improved drift reduction compared to equivalent flat fan nozzles, he added.
This year an 04 version of the nozzle has been launched to complement the existing 06 and 08 nozzles. Holmes said the smaller 04 version was likely to be useful for early herbicide applications in carrots and onions.
BCGA chairman Martin Evans added: "Developments such as the Syngenta Vegetable Nozzle provide practical solutions to help growers deliver better results."
