Mar 26, 2010 · 0.92 Atrazine is essentially useless; try looking at Scott brand of St. Augustine weed & feed, I believe it contains 1.23% or so; actually for the home owner Lesco with peloxalum (or something like that since my supply is under 25 50lb bags 0f 10-10-10; I'm sure that some-one will correct me )is more effective especially on broad leaf.

Jan 7, 2016 · All atrazine products with an ai load above a particular threshold (I don't remember what the number is right now) are labeled as restricted use. But, those under that threshold are not. Also, the lower concentration allows larger amounts to be measured for mixing, which is easier for small operators and homeowners.

Nov 5, 2013 · Dimension is marginal at best, atrazine seems to work much better. the worst annual bluegrass is actually in a predominantly St. Augustine yard that has a 50 sq. ft section of common Bermuda. the blue grass comes up in the Bermuda, which I cant treat with atrazine upon poa annua germination because I am afraid I will kill the Bermuda and leave ...

Feb 5, 2012 · The product used was "Image herbicide for St. Augustine grass and centipede grass with Atrazine" Active ingredients: Atrazine 4%, Related Compounds .08%, Other Ingredients 95.92%. I used it to kill Chamber Bitter. I followed package instructions. It is a hose-end spray type bottle.

Apr 15, 2012 · Atrazine is slow to damage some things. It may still be working. The old atrazine (RUP), not the 4% mixed with a product named Basagran, would work quicker. However the old atrazine was 40%. I agree with the EPA on this one as Atrazine moves horizontally in clay and loam and quickly moves downward in sandy soil into the water levels.

Aug 13, 2019 · I've found about 70% control of poa from mixing atrazine, prodiamine, and msm. Cheaper than spectacle, but not as good. So I use Spectacle and msm. Those results were from doing 2 fall simazine apps, followed by a winter (January …

Mar 4, 2005 · The atrazine is working great. I've been told by some other applicators in my area that they won't use atrazine once the bermuda starts to green up because it'll stunt it. I've already treated all of my existing customers in early February with atrazine. Now, new customers are calling for weed control.

Oct 11, 2017 · Simazine is also well tolerated by non dormant Zoysia and Bermuda. In the past, I used it on non dormant, actively growing grasses. However, it does have slightly less of a post emergent activity on weeds vs Atrazine explained by its lower water solubility. It can also last longer as a preemergent due to that property as well.

Jun 8, 2008 · If you are a home owner, Go with Weed & Feed, it still has the same AI or percent of Atrazine and can be purchased any where. Spot treatment with watered down Atrazine only after 30 days or longer of Weed & Feed. CPO can still buy 4L Atrazine as a RUP and must keep records of every drop used. There are too many alternative herbicides to list here.

Mar 12, 2009 · Atrazine isn't used much around here, but I know they do down in Texas, especially on St Augustine as a post. Dow has a new chemical called lockup that is an atrazine replacement. The difference between Houactinite and Milorganite is Houactinite has more jalepeno, Milorganite has more cheese.
