Without flower to help id. I'm guessing Alligator weed.
We have been fighting it the last several years. Speedzone is the only thing we have found that knocks it good.

Speed zone southern is a 3 way herbicide that has had a St Augustine Label until some one in the Tampa area over applied it in hot weather. As result Gordon's took St A. off the label as a tolerant turf. It is still labeled for turf and therefore both legal and effective weed killer on St Augustine if applied correctly.

BTW there are still a few non name brand 3 way herbicides with St A. still on the label.

Thanks everyone for all your assistance. I was able to find a strand that had a flower so here it goes.

Yes Speedzone Southern.
We stop applications with it when temps. get above 85 degrees high during the day. We add a little surfactant with it as well and have great results on alligator weed.
Had you applied Atrazine or Simazine to the areas in the picture? That is the effect we see after an application of either one of those products. Yellowing of the veins almost like chlorosis.
Here is a link to check out. http://plants.ifas.ufl.edu/node/33 Check out the video on the right hand side of the page. It may help you with a positive i.d.

A combination of the low rate of Speedzone Southern and metsulfuron will remove this weed. Best to apply this before it gets too hot.

Howdy Ric!

I think Trimec 992 does not have it on the lable on the interweb but the jug I picked does.

Hope life is treating you well.


Too bad people not reading the lable are taking away our toys.

People plain not using their brain when applying chemicals is a part of this too. Just because you can does not mean you should do something. I have not seen horrific damage caused by herbicides on st augustine or other warm season grasses. Then again, I use my brain. No applications to starved lawns, dried out lawns or improperly mowed lawns. Also when a product says so much per acre or 1000 sq ft, that does not mean I throw in an arbitrary amount in a 4 gallon backpack. The equipment used to apply is designed to put down fixed volumes per areas covered. I have given out the rates and mixes I used with the warning not to try "spot spraying" them. That mix I gave out for alligator weed is not to be "spot sprayed". I was at a golf course yesterday and was horrified to see the roughs and fairways look like a missile test site. There is no reason for that.

I agree loved using speedzone and threeway on st Augustinen. Idiots ruining the business just like everything else. Here's a good question for you guys: Why not make it harder to be an applicater then take away all the good stuff?

Isn't it already hard to become an applicator in your state? That does not fix the combination of ignorant and stubborn teaching the new guy how to be the same way. Not saying that I am perfect. In some cases, I do not kill 100% of the weeds in the first application. But burning stripes, spots or the entire lawn out does not happen. Here, if it is not windy or raining, the temperature is pushing 90. I would not apply in the wind or rain. Lawns can tolerate the label rates of products if they are not starved, dried out or going through anything else that compromises their growth. Therefore, as the applicator, I exercise control over the water and fertilization or no deal. It is not as simple as spraying the lawn and tagging and flagging.

You can spray under someones license as a cardholder with no experience and trust me I have seen my fair share of them while I trained for scotts. Hired a lot of people with zero experience on lawns and never even thought about chemicals. Am I the only ocala guy here? Just curious

Alligatorweed is actually a aquatic weed and normally only found on over watered lawns. Mowing actually spreads Alligatorweed by vegetative propagation. Recommend Aquatic chemical suppression include Glyphosate and 2,4-D which is one the herbicides in 3 Way. However Triclopyr is listed as a control. Once the Alligatorweed hits land 2,4-D will control it. Remember Alligatorweed grows as a Emersed plant or under water but does break the surface.

Same story on Lesco 3 way. Only I have a PDF label down load saved on my computer with St A listed as a tolerant turf. Once again a CYA move by the manufacture because of miss application. Today's Lesco Three Way is the formulation as my label and I have never had a problem with it.

BTW a Common problem with St Augustine herbicides because St Augustine is so susceptible to over application of herbicides. Yes people who don't read the label are hurting both the environment and our industry.

I think its Old World Diamond Flower. The herbicide Q4 will get it, but I don't believe Q4 has a label for St Aug. I have used Q4 in bermuda and gotten control. Its a tough weed.
