Sureguard for post emergent poa control
Has anyone used this product as a post emergent for poa annua? If so, how does it compare with Revolver?
This label under general restrictions says do not apply to turfgrass. Maybe valent hasn't updated the google search.
For Poa there are a lot better and cheap products. I think sureguard will cost $500+ for a couple of pounds.
I did go to the website and you are correct. It's only for dormant Bermuda. I'd still be cautious about doing it. I sprayed a sureguard and gly mix in my lawn to test it's control of weeds in beds. It keep a nice "dirt" square for months.
When you break it down, Sureguard costs about 25% more than Revolver, but Revolver doesn't prevent and suppress:
birdseye pearlwort (suppression)
bristly foxtail (suppression)
bristly starbur (suppression)
broadleaf plantain (suppression)
buckhorn plantain (suppression)
California lovegrass (suppression)
Canada thistle (suppression)
Eastern black nightshade
fall panicum (suppression)
giant foxtail (suppression)
green foxtail (suppression)
green kyllinga (suppression)
ground ivy (suppression)
large crabgrass (suppression)
prickly sida (teaweed)
redstem filaree (suppression)
smooth crabgrass (suppression)
Southern crabgrass (suppression)
Texax panicum (suppression)
This is the first year I am going to use it. I am interested to see the results.
I just wanted to update what I have seen after using Sureguard for 400-500 customers. It worked better than any product I have ever used at preventing poa from coming up when sprayed in the late fall. Just blows simazine out of the water. Lawns look perfectly clean. It was slow to kill poa when used as a post-emergent (temps below 50 degrees), but it definitely worked. I would say it killed 80-90% of the poa even in cool temps. It did take about 3 weeks for the poa to turn yellow, but once the temps got in the mid 50's the kill time has been cut in half. A very expensive product, but one that works very well from what I have experienced. I'm interested to see how well it keeps broadleaf weeds and crabgrass from coming up. The only thing that it hasn't controlled very well was henbit, but that is a notoriously difficult weed to control.
It's expemsive and have been told that the Bermuda needs to be fully dormant to use....if there is any "green" when you do spray you. Will have brown dormant grass very fast.
We treat all types of warm season so simazine works great for us. We can apply it in November and most of the time the control is still there in feb/march when we come back for round 1.
Atrazine has worked for me if time is not issue but money is, and I just sprayed celsius this week so I am seeing how that work on it too.
