Always check the exact dose on your pesticide's own label — liquid formulations are usually dosed in ml per litre of water, wettable powders and granules in grams per litre of water.

Spray Volume & Pesticide Quantity — Answered
How much spray solution does an Areca farm need per acre?
It varies by palm size and sprayer type, commonly 150–300 liters per acre for mature Areca palms — but always follow the specific product label and local agricultural extension recommendation. Enter your own figure above for an exact tank-load plan.
How many tank-loads per acre for a knapsack sprayer?
For a 15-liter knapsack sprayer and a typical 200–300 liter per acre requirement, that works out to roughly 13–20 tank-loads per acre. The exact number depends on your chosen spray volume per acre and tank size — this calculator computes it precisely for your inputs.
How do I calculate total pesticide quantity needed for my farm?
Multiply your total spray solution volume (farm area in acres × liters per acre) by the pesticide dose per liter stated on the product label. This calculator does that multiplication automatically once you enter tank capacity, area, and dose.
Is pesticide dose measured in ml or grams?
It depends on the formulation. Liquid pesticides are usually dosed in millilitres per litre of water (ml/L); wettable powders and granules are usually dosed in grams per litre (g/L). This calculator supports both — check your product label to know which one applies to you.
Is this spray calculator free to use?
Yes — completely free, works directly in your browser, and doesn't require signup or an app download. It's built and maintained by KITE Agro for the Areca farming community.
