The Herbi 4 incorporates Controlled Droplet Application (CDA) technology, enabling users to reduce application rates and minimise spray drift. As lower water volumes can be used with the Herbi-4, the number of mixing and filling operations is reduced and offers benefits to operator safety.
It can use CDA formulations or traditional water-based products at total spray volumes of only 10-30 litres/hectare. The consistently large spray droplets of around 250 micron minimise any risk of spray drift and fall in a precise 1.2m wide circular spray pattern.
Over 3 kilometres (about 0.4 hectares) can be treated in one hour.
