What this means
A pesticide label gives the dose per hectare, but in the field you mix by the tank. This converts the label rate to your area: 405 mL product split into 27 tanks, with 194 g of active ingredient actually applied.

Next: mix 15 mL of product into each of 27 tanks; that delivers the labelled rate and a total of 194 g active ingredient over the field.

Tank counts round up to whole loads; the last tank may be part-filled. Always agitate, wear PPE and follow the product label for compatibility and timing.

From a label rate to exactly what goes in each load

Pesticide labels give a rate per hectare, but you mix by the tankful. Getting from one to the other is where mistakes creep in — too little product and the pest survives; too much wastes money, risks crop damage and pushes residues over the limit. Converting the per-hectare rate over your real area into total product, tanks and product per tank keeps every load at the correct dose from the first fill to the last.

This tool gives the total product, number of tanks, product per tank and total active ingredient from your rate, area, tank size and product strength. Use it to measure out product before you start and to check the active ingredient stays within label limits. Pair it with the Spray & Tank Mix, Dilution Ratio and Herbicide Dose calculators for a complete mixing plan.

Frequently Asked Questions

What does a pesticide rate converter do?+

It turns a label rate given per hectare into the practical numbers you mix: the total product for your whole area, how many sprayer tanks that takes, the product to add to each tank, and the total active ingredient applied. That bridges the label rate and what you actually pour into the tank.

How is the total product calculated?+

Total product = per-hectare product rate × area in hectares. For example 2 litres/ha over 8 ha is 16 litres of product in total. From there the tanks, product per tank and active ingredient all follow from your tank size and the product's concentration.

How are the number of tanks worked out?+

Tanks = total spray volume ÷ tank capacity, where total spray volume = water rate per hectare × area. The product is then divided evenly across those tanks so each load carries the correct dose. A partial last tank gets the remaining product and water.

What is the active ingredient and why convert to it?+

The active ingredient (a.i.) is the part of the product that actually controls the pest; the rest is carrier and additives. Total a.i. = total product × the product's concentration of active ingredient. Working in a.i. lets you compare products fairly and stay within label and residue limits.

Why split the dose across tanks?+

Most sprayers cannot hold enough water to cover a whole field in one fill, so you mix several tanks. Dividing the total product evenly by the number of tanks keeps the rate per hectare constant across the job — under- or over-dosing a load wastes product or risks crop damage and residues.

What units does it accept?+

It works with metric label rates (litres or kilograms per hectare, grams of a.i. per litre or per kilogram) and your area and tank size in the units you use. Enter the figures from your label and sprayer; the conversion arithmetic is the same regardless of crop.

Does the water rate change the product needed?+

No — the product needed is set by the per-hectare product rate and area, not the water volume. The water rate only changes how many tanks you mix and the concentration in the tank. Keep the product rate fixed and adjust water for good coverage.

How does this relate to a tank-mix calculator?+

This converter focuses on getting the per-hectare rate into product per tank and total active ingredient. The Spray & Tank Mix calculator is for combining several products in one tank. Use this first to size each product, then the tank-mix tool to load them together.

Are the results exact?+

The arithmetic is exact for the figures you enter. Real accuracy depends on calibrating the sprayer so the actual output matches the planned water rate, and on reading the label concentration correctly. Calibrate, measure carefully, and keep a spray record.
