Batch-it: Chemical Batching & End-of-Job Reporting Companion

Key Features & Guidance
- Converts OSST label rates to equivalent chemical concentrations for a standard 100 L/ha application rate.
- Ideal when your product label provides an OSST (Optical Spot Spray Technology) rate - simply input the single (isolated) nozzle rate from the FN App.
- Important safety rule: Ensure the spray width equivalent does not exceed 100 L/ha to stay within label compliance.
When to use conventional rates instead
- If any product in your tank mix lacks an approved OSST rate (i.e., no registered 100 L/ha spot-spray rate), switch to overlapping nozzles, side-by-side safety buffers, or full broadcast application - and follow the standard conventional label rates.
