Carbendazim Spray Dilution Calculator
Work out exactly how much carbendazim to add per sprayer tank and for the whole field, from the label dose per acre and your spray volume.
Being systemic, carbendazim is absorbed and moves in the plant — but pathogens develop resistance quickly, so rotate it with non-systemic (multi-site) fungicides.
Always follow the product label — the label is the law. Verify doses, PHI and compatibility with the manufacturer and local regulations before spraying.
Farmers and spray operators use the free Carbendazim Spray Dilution Calculator to mix the correct amount per tank — avoiding the under-dosing that wastes a spray and the over-dosing that wastes money, harms the crop and breaches residue limits.
About Carbendazim Spray Dilution Calculator
Getting pesticide dilution right is the difference between control and a wasted, possibly harmful spray. Carbendazim (50% WP), a systemic fungicide, is used at about 1 g per litre. This calculator takes the label dose per acre, your spray volume per acre and your tank size, and works out how much carbendazim to add to each tank, the total product for the field, the concentration per litre and the number of tank loads. The product label always takes precedence — doses here are typical values to plan with.

Frequently asked questions
How much carbendazim do I add per litre of water?+
Carbendazim (50% WP), a systemic fungicide, is used at about 1 g per litre. The exact rate is on your product's label — divide the label dose per acre by your spray volume per acre to get the per-litre concentration, which this tool does for you.
How do I calculate carbendazim per sprayer tank?+
Per-tank dose = label dose per acre × tank size ÷ spray volume per acre. For example, 200 g/acre at 200 L/acre in a 15 L tank is about 15 g per tank.
Why must I follow the label dose exactly?+
Being systemic, carbendazim is absorbed and moves in the plant — but pathogens develop resistance quickly, so rotate it with non-systemic (multi-site) fungicides. Over-dosing breaches Maximum Residue Limits (MRLs) and can be illegal; under-dosing fails to control the pest and breeds resistance. The label is legally binding.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the field and your data never leaves the device.
