## Questions & Answers

**Q: will it work with no pre mixing sprayer connected to water hose? if so, is setting of 2tsp for one gallon will work?**
A: Prodiamine is a dry granular product meant to be mixed with water and when PROPERLY applied, is an excellent pre-emergent weed control product.  
Because the mixing rate is so precise and the application rate is so critical, the manufacturer does not recommend using a hose end spraying device for application.  That being said, and if you are still determined to try, here’s what’s involved for one, 6 month control application. First, divide your lawn into smaller, measured 1, 2, or 3 thousand square foot “lots” and mark off each lot EXACTLY using stakes and/or flags.  Next, weigh out 0.367 ounces of Prodiamine per 1000sf area you’ve marked off. Given that a teaspoon of Prodiamine weighs ⅛ or 0.125 ounces then, for example: a 2000sf lot gets 0.734oz or 6 teaspoons of product.  Mix that (or whatever your marked lot size calls for) into a one quart jug of water.  That will be your concentrate for that lot.  Fill the hose end sprayer’s reservoir with the concentrate and set the mix rate on your sprayer to 4oz (liquid ounces) per gallon.  That rate should dispense 8 gallons of water before using up your 32 ounces of concentrate on the 2000sf lot.  A good rate would be anything more than ½ gallon per 1000sf -  the manufacturer’s minimum.  Spray away, evenly wetting only the marked off area, refilling the reservoir as needed until you’ve used the entire quart of concentrate.  It does not matter how much water you apply.  It only matters that you applied all the concentrate (containing the correct amount of Prodiamine) in the marked off area as equally as possible.  Too much and you risk harming the lawn, too little and you won’t get the weed control you hoped for.  Repeat the process by mixing a new quart  of concentrate using the appropriate amount of product for the next size lot.  If necessary, adjust the sprayer’s distribution rate to YOUR pace to ensure the best uniform coverage.

**Q: Will it prevent crabgrass?**
A: Yes.  Prodiamine is broken down by the microbes in the soil, and the microbes do not really start to become very active until the soil temperatures are higher...like 50+ degrees (not 100% positive of what temp here, but you get the idea).  Crabgrass seeds start to germinate once the ground temperatures start to reach about 55 degrees.  So you can put this down when the ground temperatures are 40-45 degrees and it will still be very effective once the ground temperatures reach ~55 degrees and provide the protection you need, versus waiting until the ground temps are already at 55 degrees and you may be too late.  What this does it once the crabgrass and other seeds start to germinate, Prodiamine will stop the roots from progressing once the seeds start to germinate, which kills the plant before it completely germinates and breaks through the soil.  What I like to do (heard this from a lawn care professional - YouTube channel 'Pest & Lawn Ginja') is get use a cheap meat thermometer and check the soil temps and once the ground temps are around 55 degrees, put down a different pre-emergent called Dithiopyr.  This will also stop seeds from fully germinating as the Prodiamine does, but Dithiopyr also acts as a post-emergent for very young weeds and crabgrass up to 2-3 tillers.  So you get early protection and a second layer of protection if required.

**Q: Is this product safe for centipede grass thats 1 year old?**
A: This should be safe on any established grass which typically means the grass has grown enough to be mowed 4+ times.  You can put it down a little earlier depending on the grass type, but better safe than sorry.  If you put this down too soon you can harm the new grass while it is maturing and if you do this, the prodiamine will stop new grass seed (as well as weeds) from germinating for a few months.

**Q: How often do you need to apply this treatment**
A: As often as you want as long as you do not go over the maximum amount for your turf type per year.  For some turf types, that is about .83 ounces by weight of this dry granule per 1,000 sq. ft.  Most typically people apply this in the late winter or early spring.  Many say to put this down when the soil temps are at 55 degrees in the winter/spring, but that is when crabgrass starts to germinate.  Many lawn care professionals say to put this down earlier, when the temps are 40 to 45 degrees because it is the bacteria in the soil that break down the product and at these temperatures, the bacteria are pretty much dormant.  You apply at 0.185 ounces by weight per 1,000 sq. ft. (for any grass type) and that will give you 3-4 months of protection when put down at those temps above.  Put down 0.28 ounces per 1,000 sq. ft. to give 4 months of protection in the fall.  I apply when the night time temperatures start dropping into the low 70's and upper 60's.  I saw someone say you want this down before the soil temperatures drop to 70 in the late summer/early fall, but I have not confirmed this.  So if the day temps are in the 80's and 90's and the night temps are in the 70's or upper 60's, you should still be ahead of the annual weeds you're trying to prevent in the fall.
