The Herbi Duo Range

Herbi Duo Electric Handheld CDA Sprayer for Herbicides

The Herbi Duo range offer the latest development in Controlled Droplet Application (CDA) technology, enabling unparalleled drift control at very low spray volumes for herbicide application with a lightweight and ergonomic spray lance. They can be used with any herbicide which can be used at lower water volume rates (such as Glyphosate) at total spray volumes of only 15-30 litres/hectare.  All models in the Herbi Duo range offer two spray band widths of 1.0 m and 0.4 m achieved by simply changing the atomiser disc from large to small. Drop sizes at 1m band are in the range of 200-300 µm VMD and a larger drop size of 650-750 µm VMD when using the smaller 0.4m band An optional spray shield is also available when spraying with the narrow 0.4 m band which can be used to avoid any risk of spray contact with adjacent vegetation.

The Herbi Duo can treat over 3 kilometres (about 0.4 hectares) of fence line using one 5L tank mix. Applications include general clean-up, border, pathway and strip spraying (e.g. in orchards and plantations) and spraying of larger areas by making consecutive spray passes. The reduction in mixing and filling operations (with no mixing required with CDA formulations) offers operator safety advantages.

The Herbi Duo+ is a high quality model with an ergonomically designed handle featuring a trigger lock, armrest and easy to access atomiser on/ off switch. The Duo+ is powered by 4x R6 AA size batteries.

The Herbi Duo model comes with a simpler handle and armrest option with atomiser controlled via a battery switch at the end of the sprayer. The Duo is powered by 4x R20 D cell batteries.
