If label says 2 oz/acre at 20 gal/acre spray volume, each 100 gal tank (5 ac) needs 10 oz product.
Product = (Tank Volume ÷ Gallons per Acre) × Rate per AcreFor wettable powder or liquid concentrate diluted to spray solution percentage per label.
Stock to Add = (Desired % × Final Volume) ÷ Stock %Fill tank partially, add product, agitate, fill to volume. Never add product to full tank without agitation.
Water = Tank Volume − Product VolumeUpdated: July 2026
300 ÷ 25 = 12 acres per tank × 1 pt = 12 pt (1.5 gal) product per tank load.
Covers 2 acres per fill. At 1 oz/acre product rate → 2 oz per backpack tank.
300 gal tank needs 3 lb WP. Pre-slurry in water before adding to tank.
Mix pesticides and herbicides at correct label rates for backpack, ATV, and tractor sprayers. Enter product rate per acre or per gallon, tank capacity, and application volume to calculate product amount per tank load safely.
