Typically, apply fall pre-emergent between Sept. 1 and Sept. 15 to control winter weeds. Specifically, apply when soil temperature is 70 degrees and declining.
The first thing you need to know when using an herbicide such as Prodiamine 65 WDG 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 0.185-0.55 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 0.185-.55 oz of product with for each 1,000 sq ft area that needs to be treated.

Trimec is used when weeds have already sprouted and are actively growing in temperatures between 65 and 85 degrees, which is not the appropriate time to use Prodiamine 65WDG.
