Precision aerial herbicide application for gorse, thistles, ragwort, and pasture renovation — on terrain where ground equipment can't go.
Steep faces, wet ground, streamside margins, and dense scrub have traditionally been impossible or dangerous to spray from the ground or by helicopter at a reasonable cost.
SkyTech's BROUAV U25L-4 changes that. With GPS precision to within centimetres, variable application rates, and no requirement for access tracks, we treat exactly what needs treating — nothing more, nothing less.
Gorse is New Zealand's most problematic invasive weed. Drone application of herbicide directly into the canopy achieves superior coverage compared to conventional boom or knapsack methods — particularly on steep, inaccessible blocks.
Scotch thistles, Californian thistles, and ragwort are notifiable weeds under the Biosecurity Act. Drone spraying allows targeted spot treatment across large areas in a single operation, well ahead of seed set.
Spraying out old, unproductive swards before re-grassing. Drone application is particularly effective on hilly country where cultivation isn't practical, allowing full aerial coverage without compaction.
General scrub encroachment, blackberry, old man's beard, and other invasive species. We assess the site, select the right product and rate, and treat with minimal impact on surrounding vegetation.
From initial enquiry to signed-off spray record — here's what to expect when you book with SkyTech.
Tell us the location, approximate area, weed species, and terrain. We'll review and discuss the best approach, including product selection and timing.
We provide a written quote. Once accepted, we plan the flight, obtain any required NOTAMs, and prepare the spray plan with product, rate, and buffer zones.
Our pilot conducts pre-flight checks, confirms weather conditions are within limits, briefs any observers, and completes the application. You don't need to be on-site.
A full spray record is issued — operator, product, rate applied, area covered, wind speed, temperature. This is your compliance record. Invoice follows.
Drone herbicide application is a controlled activity under NZ law. Operators must hold a CAA Part 102 Agricultural Operations Certificate of Approval and pilots must be HSNO approved handlers for the specific products they apply.
SkyTech holds both. Engaging an unlicensed operator — however cheap — puts you, your neighbours, waterways, and livestock at legal and environmental risk.
