Independent testing confirms what precision can achieve
Independent testing by Wageningen University & Research (WUR) has shown that Kilter AX-1 qualifies for DRT99 classification, the highest drift reduction class in the Dutch system for spraying technologies.
The testing demonstrated more than 99% drift reduction compared with conventional reference spraying systems.
The result validates the technology behind AX-1.
Precision reduces drift
Conventional spraying systems are designed to spray evenly across the field.
AX-1 works differently.
The system detects individual weeds and applies herbicide only where treatment is needed, with 6 × 6 mm precision.
The result is highly precise application with very low drift.
According to the Wageningen report, spray drift in realistic operating conditions was described as "essentially zero".
The testing also included worst-case scenarios and simulations carried out without sheeling at higher driving speeds than the machine currently operates under. Even then, AX-1 maintained DRT99 performance.
Why this matters
Lower drift is an important achievement in itself, but for growers the benefits extend much further.
By applying herbicide only where it is needed, AX-1 minimizes unintended exposure of the crop. Compared with conventional spot sprayers, this reduces the risk of phytotoxic effects and helps maintain a healthier and more even crop. Since these crops are harvested in a single pass, a more even crop puts a much higher share of the yield within the sellable range. A healthier crop also matures earlier, which often means a higher market price.
It also means crop protection products are used where they create value, rather than where they are not needed.
Because AX-1 qualifies for the highest drift class, it can work closer to ditches and waterways than conventional spraying, putting more of the field to productive use.
An important milestone
The Netherlands has some of Europe's strictest requirements for spray drift.
The DRT99 classification is therefore an important step for commercial use in the Dutch market and supports Kilter's ongoing work in other European markets.
For us, the result is confirmation that precision application delivers measurable benefits.
Not only for drift reduction, but also for crop health, grower profitability, the surrounding ecosystem and the future of precision crop protection.
