CDA stands for Controlled Droplet Application.

The targeted application of fine droplets with a defined spectrum at low spray volume is made possible by a rotating nozzle disc.

Uniformly sized droplets are formed on its serrated edge and centrifugally flung outward, where they then fall down due to gravity.

Comparison of CDA to conventional nozzle

Instead of the usual 300 - 600 liters of spray liquid per hectare, approximately 10 – 30 liters per hectare suffice with the same herbicide application rate; the preparation is therefore applied more concentrated.

There is long-standing practical experience with glyphosate products (e.g., Roundup® UltraMax and Basta®). Depending on the device type, the droplet size is about 200 – 300 µm. The result: optimal distribution with minimal drift risk. 

Advantages of CDA Devices

Operational Efficiency:

• Cost savings through reduced use of spray agents and water
• Droplet distribution and uniform droplet size for better spray results
• Significantly faster spraying process

Increased Productivity:

• Much less spray liquid needed compared to conventional nozzle technology
• Significantly reduced time required
• CDA handheld devices greatly reduce physical effort compared to conventional backpack sprayers

Safe Spraying:

• Reduced user errors due to fatigue, as the process is less strenuous than with a backpack sprayer
• Fewer mixing and filling operations, where contamination is most likely

Lower Environmental Impact:

• Reduced water demand
• Lower soil contamination compared to spraying with a nozzle, as well as much more targeted application
