The front-mounted machine, developed from a single-bed machine trialled on carrots last year, uses Micron's established Controlled Droplet Application (CDA) technology, which allows the use of total herbicides like glyphosate in row crops including onions, carrots and leeks.
The new machine takes the Environmist shrouded spray head and adapts it to vertical application.
Each shroud measures 90cm wide but is turned to run between the crop rows and can be adjusted to any row spacing from 90cm down to less than 8cm, the company claims.
The three-row machine on display at LAMMA was already on its way to a large carrot grower. It featured three centre spray heads to accurately target weeds growing between the four crop rows, and two more to spray the wheelings or between beds.
A "sophisticated but simple to operate" control system allows monitoring of each individual head.
The Vegemiser can be twinned with Micron's non-dripping WeedSwiper to selectively control taller weeds growing in the row without touching the crop.
