When using Lontrel Turf and Ornamental Herbicide for Dollarweed, the product label calls for ½ fl oz (15 mL) per 1,000 sq ft. The first thing you need to know when using an herbicide such as Lontrel 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. 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. That is the amount you will want to mix the specified amount of product with for each 1,000 sq ft area that needs to be treated.
