Seeing that they’ve already sprouted, your too late. A month ago is when you should have applied prodiamine. Putting it down asap could still catch the first die off seeds of dandions and maybe crabgrass.

 

Ok. Thanks. Will get it down tonight.
Water it in?
With wetting agent or without?

 

I dont believe the label for Prodiamine calls for any wetting agent. Yes, it must be watered in. Barricade (Prodiamine) calls for 1/2 of water after application. You want the product down in the soil to create the barrier. As stated above, you may not see any difference as your late and everything may have germinated already. The pre emergent should be applied when the soil temp is rising to 55 deg F. Your application time was approx 10 April. You can see your local soil temp using this link for the fall preM app when soil temp drops to 70 deg F.

 

Well darn it.

I’ll skip this application and get it down in the fall.

will just have to invest in the Velocity PM I guess.

 

You’ve got so many products already, but it sounds like you’re not quite sure of which to use for what, and when. I feel like I’m reading the story of an addict….”one more $700 bottle will fix it, I’m sure of it”.

Take every product you have and thoroughly read the label.
Make a table on your computer: when do I apply, what is its goal, rate per 1000sqft (or amount for front yard/amount for back yard), water in?, surfactant?, etc.
Then you can build out a calendar for what you want to put down, plan purchases, have rational for your decisions, instead of looking at a $700 bottle meant for warm season grasses an has warnings on it about destroying the type of cool season grass you have.

 

Point taken… But That was a joke. Sorry it didn’t come through as that.

700is a bit steep for Something that may or may not work.

I was looking to split a bottle so that I could test the validity of the product as well as see what it might do to the KBG in my lawn.

I do keep a lawn journal but was missing this application.

Moving the journal to a spreadsheet is a good idea.

Aren’t we all just a little addicted to this stuff?

 

I have used the YardMastery App for 4 years in which gives you great recommendations on your local temp and best times for preventive and fertilizer applications. It's a great tool for monthly herbicide/fertilizer applications. Typically, best time for Prodiame is early spring and another application then mid fall. However, if you plan on overseeding in the fall, you are better off utilizing Prodiame in spring.

 

Yes, I use that app as well. It’s actually specifically because of this app that I am wanting to put together an easily updatable version.
This years reminder for pre-em was a bit late. Received that notice this week and it’s probably already too late here in Seattle. Looks as if our average 5 day is in the high 50s

 

True, but YM is an estimate. Stick with post emergent if you didn’t get your pre emergent down. Preferably, once it 70 degrees in spring is the best time for first app of pre emergent. Better yet put down a grub control too. I’ve been very paranoid about grubs as this stems from 2016. I put down the Grub control Menards bag with Iron Pro. So far I am in position to control grubs before they eat the grass roots while feeding more iron in the lawn. Always think of putting something down in your lawn to prevent or enhance.

 

I mowed and put the prodiamine down tonight. 11grams over a little bit more than two gallons of water and sprayed it. Followed with a healthy drink of water.
Will cut it again over the weekend and hit it with nitrogen again. 24 ounces of def over two gallons of water.

any recommendations on a post emergent to git rid of poa and some crabgrass?

 

I guess I should get some insect control down now as well. If the raccoons find even a couple of grubs they hang out every night and tear the joint up.
