Start with the controlling label
RanchAssist does not recommend a pesticide or herbicide product or rate. Read the product label and enter the legal labeled rate yourself.
Enter project acres and target GPA
Total carrier volume is based on acres × gallons per acre. Tank size then determines approximately how many full tanks are needed.
Enter each product separately
Use the rate unit that matches the label, such as oz/acre, pt/acre, qt/acre, gal/acre, oz/100 gal, percent solution, or a supported custom basis.
Per-tank instructions
The calculator converts total requirement into product per full tank and an exact partial-last-tank amount for the remaining acres.
Do not round the last tank into a full tank
The final tank should match only the acres that remain. Review both remaining carrier volume and product amount before mixing.
Label remains controlling
The label governs legal rate, PPE, restrictions, re-entry, grazing/haying intervals, environmental precautions, and tank-mixing requirements.
