NEW: Optik Driftless – Spray Drift Control

The problem of Spray Drift

Spray drift remains one of the most common challenges in liquid applications, whether applying fertilisers or plant protection products. When fine droplets drift away from their intended target, they not only reduce the effectiveness of the product but also risk environmental contamination and off-target movement. This issue is particularly problematic on exposed sites, where wind and weather can make spray windows few and far between. Achieving precise, efficient spray delivery is therefore important for both product performance and environmental stewardship.

Research shows that spray droplets smaller than 90 microns are the most drift prone. These lightweight droplets can easily be carried by wind or air turbulence, reducing the amount of product reaching the plant and lowering efficacy.

The development of Optik Driftless

Optik Driftless has been developed to tackle this problem directly. It contains a mixed adjuvant formulation that reduces the formation of drift-prone droplets while also improving spreading, wetting, and sticking on the leaf surface. The formulation includes a spray buffer to help balance pH, improves rain fastness of applied products, and provides some protection from UV degradation — ensuring sprays perform as effectively as possible once applied.

In trials, untreated spray solutions produced 46% of droplets under 90 microns, while adding Optik Driftless at just 500ml per 100lts reduced this number by an average of 20%.

Importantly, this improvement in droplet control did not lead to an increase in overly large droplets that risk bouncing or running off the target — with 90% of droplets remaining below 300 microns, ensuring effective plant coverage.

For added convenience, Optik Driftless is also available in our unique OneShot sachets, as Optik Driftless OneShot, providing an easy-to-use, economical and pre-measured packaging option ideally suited for both pedestrian and drone sprayers.
