PHL provide aerial services to the New Zealand forestry industry

PHL provide aerial services to the New Zealand forestry industry. Key areas we've been involved in are spraying in preparation of land for planting, maintenance of established trees along with fertiliser application, fungicide release and spraying.

PHL's Key Roles in the Forestry Industry

PHL - Agricultural Services - Helicopter Forestry Development

Pre-Plant Spraying

This is where we use a residual herbicide prior to planting to prevent competitive weeds from choking the new trees for the first six months ensuring they have a good start.

Release Spraying

Sometimes after 12 months, trees require another spray of selected herbicide to cut out the competition.

Fungicide Spraying

PHL have all the helicopter equipment to apply Copper Oxychloride to prevent Dothistroma septosporum. H3ClCu2O is applied at very light rates with oil through our micromere nozzles.


In Southland, we've been involved in applying granular urea to forestry crops at 300kg/ha. This aerial application is carried out in the spring and is giving our clients very good growth rates.
