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-.055 oz of product with for each 1,000 sq ft area that needs to be treated.

Yes, that should be fine to mix your pre-emergent like Prodiamine with a post-emergent like Battleship. Just be sure that you are using the correct rates for your turfgrass and for the area that you are treating, and that the pre-emergent is activated within 14 days of application. You may want to do a small jar test for compatability if it is your first time mixing these two products together.
Prodiamine should not be applied during rain. It is preferred to apply prior to a rainfall or wait 24 hours following a rainfall. Be sure to irrigate the area after the product has been applied to activate it. Pre-emergents need to reach the thatch area to prevent the weeds from germinating, so irrigation is very important.

Prodiamine 65 WDG is safe when used as directed around ornamental plantings. It is only a pre-emergent, used to prevent weeds emerging. It will not kill anything that is actively growing.

Prodiamine 65 WDG (Generic Barricade) would be a good pre-emergent option for you. It is labeled for most common weeds.

We do have a Lawn Care Schedule on our site with general time frames that may also be helpful.
Prodiamine 65 is a great crabgrass and general broadleaf weed preventative product. For crabgrass your main application for prevention will be in the spring when it germinates. You are welcome to do a fall application now for other weeds, too, but you will want to get it down before Oct 1st, ideally, in our southern region. Keep in mind that pre-emergents will not do anything to the crabgrass currently growing in your lawn: you would need a post-emergent product for eliminating those.
