How to Calculate Tank Mixing
Tank mixing is the process of combining one or more pesticides in the same solution for spraying on your crops. It is important to know how to calculate your ingredients so that when you mix pesticide with water, you get a sprayable solution. To determine the composition of your solution, you need to determine the amount of product that you want and the amount of water you will need for that product. Follow these steps to calculate your ingredients for tank mixing. Does this Spark an idea?

1
Determine the number of acres that you need to spray. If you have measurements in square feet instead of acres, divide by 43,560 to find the amount of acres you have. For example, 1000 square feet is .02296 acres.

2
Read the labels on your pesticide product. Find the number listed for the specification "pints per acre."

3
Divide the number of pints per acre by 8. This will give you the number of gallons recommended to be sprayed per acre, since there are 8 pints in a gallon. Record that number on a sheet of paper as gallons per acre.
-
4
Multiply the gallons per acre figure that you just calculated by the number of acres you have to spray. The result is the amount of product you will need, measured in gallons. Record this number as the amount of product needed.

5
Inspect your sprayer's specification sheet. Find the listing that tells you how many gallons it sprays over an acre area. Record this number as sprayed gallons per acre.
-
6
Multiply the number of sprayed gallons per acre by the total number of acres you have to spray. From that result, subtract the amount of product that you need to determine how many gallons of water you will need to mix with your product.

Tips & Warnings
When mixing more than one kind of pesticide, find the gallons per acre for each pesticide individually. Add these individual numbers together. The sum of those numbers is what you will subtract from the sprayer computation to determine the amount of water that you need.
