We are happy to assist you with your question, however we there are a few steps you need to take to make sure you are using the correct amount of product for your application.
When using a pre-emergent such as Prodiamine 65 WDG (Generic Barricade), there are going to be a few factors to determine how much product you need to use in your sprayer, mostly what kind of turfgrass you have and how large the treatment area is. You also want to take into consideration how many applications you are making per year so that you do not exceed the annual maximum rate for your kind of turfgrass.
For example, if you have Bermuda grass, the product label indicates that you can use a maximum of 0.83 oz per 1,000 sq ft per year (Table 1 on page 9). If you are making 2 applications per year, that would be 0.415 oz per 1000 sq ft per application. If you are using your 16 gallon tank to treat 16,000 square feet, then you are using 6.64 oz of Prodiamine 65WDG per tank.
While weighing a granule is the best way to insure you are using the correct amount of product, there is a volume chart on page 14 of the label. The 0.4 oz rate would be equivalent to 1.25 tablespoons per 1000 sq ft. So 1.25 Tbsp x 16 = 20 Tbsp or 1.25 Cups per 16 gallon tank in this example.
I hope this helps to clarify. Let us know if you have other questions anytime.
We do not carry the Field King 190571 Lithium Ion Battery Powered Pump Zero Technology Sprayer so we couldn't say for certain what would be best. However based on a cursory Google search of that unit, and finding online it seems to come with the following parts: "4 nozzles included: Brass adjustable, 2 flat fans, and foaming nozzle. Also accepts Tee Jet nozzles." we would suggest using one of the flat fan spray patterns for an even straight swath of product when applying a herbicide such as Prodiamine 65 WDG to the lawn.
There is no time restriction with fertilizers and Prodiamine 65 WDG (Generic Barricade), they can be applied around the same time following each product label.
Prodiamine 65 WDG (Generic Barricade) is a pre-emergent that should be applied in early spring when the soil temps rise up to just under 55 degrees which is the temperature crabgrass germinates. Refer to page 8 of the product label for approximate crabgrass germination dates for Prodiamine 65 WDG. Without knowing what type of turfgrass you have, we cannot give the exact application rate specifically for your treatment but please refer to page 9 of the product label for turfgrass application rates.
Quinclorac would be used when crabgrass is actively growing and temperatures are between 65-85 degrees. Typically a Methylated Seed Oil Surfactant is recommended with Quinclorac for best results. Please refer to the Quinclorac product label for specific rates based on your turfgrass.

You can apply right before rain for watering in as long as not a downpour/heavy rain. It only needs to be watered in 1/2 inch.

Prodiamine 65 WDG (Generic Barricade) can be mixed with Quinclorac 75 DF Herbicide or Tenacity Herbicide. However, make sure to do a jar test prior to doing a full tank to make sure it does not stress the lawn out & to see how they react.
Please refer to each individual product label for tank mixing instructions and follow the most restrictive label.
Aerating should be done prior to applying pre emergents such as Prodiamine 65 WDG (Generic Barricade) and can be done 2 times a year if needed (March-April and August-October). Do not aerate or detach lawns after pre emergent applications as this will disturb and break the barrier the herbicide is providing against weeds.
Effective pre emergent control of weeds is relies heavily on correct timing of the application. In spring, pre emergent applications need to be done when the soil temperature average is just under 55 degrees consecutlvely for 4-5 days. In the fall, pre emergents need to be applied when soil temps begin to drop to 70 degrees and continue to cool.
Pleae contact your County Extension Office for exact timing recommendations in your area or use Syngenta’s GreenCast Soil Temperature Website for soil temperature averages and current readings.

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 (1.1 tsp-3.3 tsp) of product with for each 1,000 sq ft area that needs to be treated.
