How do I mix Princep Liquid Herbicide with water (per gallon) to spray my lawn? I will use a one gallon sprayer....


You will need to use 0.75-1.5 fl. oz./1,000 sq. ft depending on your target weed. Most folks use the higher usage rate.

The first thing you need to know when using an herbicide such as Princep Herbicide is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.75-1.5 fl. oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with WATER ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.75-1.5 fl. oz of product with for each 1,000 sq ft area that needs to be treated.
