No professional advice

Nothing on this site constitutes legal, medical, agronomic, safety, or professional advice of any kind. The calculators are designed to assist with math and unit conversions only.

Always consult qualified professionals and follow official guidance for decisions involving chemicals, pesticides, herbicides, disinfectants, equipment operation, or regulatory compliance.

Always follow product labels

Product labels and safety data sheets (SDS) contain legally binding instructions. You are responsible for reading and following all label directions, including mixing order, application rates, PPE requirements, restrictions, and disposal instructions.

If there is any conflict between this site and a product label, the label always takes precedence.

Accuracy and estimates

While we strive to keep calculators accurate and up to date, we make no guarantees regarding accuracy, completeness, or suitability for any particular purpose.

Results are estimates based on the inputs you provide and the calculator logic at the time of use. Always double-check results before mixing or applying any product.

Scope of these calculators

• Dilution math: Converts ratios and label rates into concentrate + water amounts.
• Planning math: Helps estimate coverage, tanks needed, calibration outputs, and cost per acre from your measurements.
• Compliance tools: Re-entry interval (REI) timers and WPS field posting notice generators are provided as a convenience aid only. They do not constitute legal compliance advice. Always verify REI periods, posting requirements, and WPS obligations directly against the product label and applicable regulations.
• Drone / UAV tools: Mix rate, flow rate, and job planning outputs are estimates based on your inputs. Actual drone application rates vary by equipment, nozzle selection, speed, and conditions. Always verify against your drone manufacturer's guidelines and applicable pesticide registration requirements for aerial application.
• Not provided: We do not provide product-specific application instructions, legal use rates, or safety determinations.
