The Herbi 4 is a extremely mobile rotating disk sprayer for the Controlled Droplet Application (CDA) of herbicides. But is equally adept at using traditional water-based poisons at very economical spray volumes of between 10 to 30L per hectare. A larger evenly sized droplet of 250 microns disperses in a precise 1.2m wide circular spray pattern and minimises spray drift.

The Micron Herbi 4 is ideal for strip spraying in orchards and can treat over 3 kilometres (about 0.4 hectares) in one hour.
