Is it too late to put pre-emergent herbicide down?

In granular form? I know the recommended window is late October through November but would it be a waste of time and money to put it down now?

I think if the weeds you’re trying to kill haven’t emerged you’ll be fine. If they have, go with a post emerge.

Do you have anything currently alive? What are you trying to keep from emerging?

You’re not far from needing to put pre emergents down for spring/summer weeds.

Yeah, I know. Probably going to nuke my yard next week while I don't have much going on at work... Always put it on the back burner when I start to get busy.

What do you recommend for st Aug? I've had that Virginia buttonweed like crazy the last couple years, would love to stop that shite

I sprayed 2-4-D today on a few pastures. Supposed to be above 65F before you spray but I said frick it. Hope I didn’t waste my time.
That said, it’s gonna be cold next week. Mind the recommended temp application guidelines before you put anything out.

I have a clover problem right now.

Same here (also in Youngsville area). I went to Chastant Bros and they recommended "Weed Free Zone". Used it about a day ago....we'll see if it works.

What’s the deal with 65°? Is that for protecting grass or making sure the 2-4,D is working? I’ve sprayed it when it was like high 30’s temps on land I was going to plant corn on and it did a jam up job. Like most herbicides, it’s just a little slow when it’s cold in my experience.

I’m guessing their recommendation is twofold.
One, the colder the temps, the longer the reaction time. 2-4,D usually reacts pretty quickly but cold temps could take a bit longer. During winter months, I’d just suggest that you spray with a 48 hr window of no rain or heavy fog.
Two, the surface inversion has usually lifted out of the way by the time the temps hit 65 degrees (not always but usually). What you doesn’t want to do is spray and have the chemical drift floating around in a suspension and land on off target areas.
If you spray with warmer than 65 degrees, there’s a much higher likelihood that the smaller drift particles will safely land in the target area.
Unless you grossly over apply, 2,4-D won’t impact your grasses at this point in the year.

Additionally,
Here is a link to NOAA’s fire weather forecast and it has a surface inversion lift temperature (SILT) listed. To be in the safe side, spray after the temps are above the listed SILT for your area.

It’s also a great general weather resource.

From what I’ve read, plants metabolize it better at 65F and above. Whatever that cabbage looking shite is in my pastures, it was curling up this morning so I guess they were metabolizing yesterday.

Maybe try a fall pre-emerge.
