Use the concentration and formulation on the label to convert the active ingredient rate into commercial product per hectare, or the reverse.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
How much product is needed for the same active ingredient dose at each concentration; the dot marks your product.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Each row is a dose and each column a concentration close to the one entered; the highlighted row is your dose. In dose mode, the table shows product per hectare; in reverse mode, active ingredient per hectare.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
In dose mode, enter the active ingredient dose in g/ha (per the label or the prescription) and the product's concentration. The calculator shows how many liters or kilos of product to use per hectare. In reverse mode, enter the product in L/ha or kg/ha to find out how many grams of active ingredient it delivers.
Dose of 1,440 g/ha of active ingredient, SC product with 480 g/L.
Product = 1,440 ÷ 480 = 3 L/ha. For 20 ha, it is 60 L. In reverse, 3 L/ha × 480 g/L = 1,440 g/ha.
| Acronym | Type | Reference unit |
|---|---|---|
| SC | concentrated suspension | g/L, product in L |
| SL | soluble concentrate | g/L, product in L |
| EC | emulsifiable concentrate | g/L, product in L |
| WG | water-dispersible granule | g/kg, product in kg |
| WP | wettable powder | g/kg, product in kg |
To bring the result to the tank, use the tank mix, and to adjust the spray volume, the sprayer setting.
On the product label or leaflet, usually in the composition section. For liquid products, the unit is usually g/L; for solids, g/kg.
The dose is the amount of active ingredient per hectare. The product is the amount of commercial formulation that contains that dose. Only the product goes into the tank.
Because it sets the product unit (liter for liquids, kilo for solids) and the reference concentration. Confirm the formulation before converting.
No. It only converts between dose and product. Choosing the product, dose, and timing is a technical recommendation and must follow the label and a technical manager.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor. Material and fuel properties vary: check with the manufacturer or with analyses of your process before deciding. By using the site, you agree to the Terms of Use.
