Looks like you have every weed known to man. I'll let one of the warm season folks suggest the best course of action, but I wanted to point out this particular weed which is very aggressive.

This is Virginia Buttonweed and it will spread like wildfire. Don't mow over it where clippings get thrown all over the place, each little piece will root. Don't try pulling it, it encourages more growth. Spray it with herbicide as soon as you see it, it's going to be a multi-year battle to get rid of it.

First, spectracide is the wrong product for bermuds grasses, it will stress them out. You want a product that does not use 2,4d as the active ingredient. I like sulfentrazone based products, as they kill every weed I've tried them on.

Do not bother with reseeding Bermuda, use sod as the seed is a recipe for frustration & failure. A quick search of this forum will show you 10 failures for each success. Once you factor in all the water & fertilizer & prep for seed, the sod ends up cheaper.

If the lawn is really 80% gone, I would recommend a full resod. Get on a good pre emergent schedule & a big bottle of sulfentrazone to spray every few months. That should be about all you need. Obviously mowing & fertilizing are totally different subjects

Hi Thank you for the suggestions. When I mentioned "80% gone" , I meant the particular area where the weed was...not the whole lawn. Sorry my bad. This is probably 20% of my lawn.

What about plugging from your healthy section into the bare section? Using a ProPlugger.

So if I plug from a healthy section, don't I have to seed the healthy section which just lost some grass?

Thank you..will look into it. One last question, our back-yard has a bird-feed and now it looks like the seeds were scattered and caused some pale light green grass to grow along. Going to look into getting another seed brand or just remove the bird feed. but any thoughts on how to get ride of those ?

Post a close-up picture of this light green grass.

All of this started right after this bird-feed :(.

Some of that is from the birdseed but the rest is just normal weed pressure for a Bermuda lawn, crabgrass & such. A consistent preM schedule will prevent 85% of it & the rest you just spot spray every month or 2. I live in Houston with a 9 or 10 month growing season on my Bermuda, so I do preM every 3 months like clockwork & spot spray 2 gallons of sulfentrazone every 45 days to kill off the nutsedge, spurge & crabgrass

Great thanks. Any suggestions for a good pre-emergent. Most I am seeing atleast in Home depot, Lowes is weed-and-feed but nothing is just a pre-emergent?

It's usually found blended with a fertilizer at those stores. Your local ace or nursery should have barricade prodiamine or a product containing dimension dithiopyr. If not, you can get them online. The big box stores make a lot more money off weed & feed so they don't exactly push the preM agenda

http://www.homedepot.com/p/LESCO-50-lb-Crabgrass-Control-0-0-7-052388/100121942 Lesco 0-0-7 should be a good preM right?

I can't see the active ingredient window from that pic, but you're on the right track.

Lesco 0-0-7 is pendimethalin.

It appears that Lesco 0-0-7 sold in HD is most likely different variation to what is sold at a JDL location. There are a few JDL's close by and there might be a 0-0-7 which says "Dimension" on it. There is another Lesco 19-0-7 Dimension Crabgrass but it is for the spring and I am not inclined to load the lawn with more nitrogen and will go for strictly the 0-0-7. I saw another -0-0-7 but by Sunniland and it has the following:

Dithiopyr:0.172%

Inert Ingredients:99.828% but I am not sure if the Lesco 0-0-7 at home depot has the same ingredients. I need to go to the store and see it.

I was going to apply Milorganite again in Early Sept and then pre-emergent on Sept 15th to control the winter weeds. Is this ok to do? Will the pre-emergent prevent the bermuda lawn from getting the best out of the Milorganite?

No, a preM can slow down rooting of new sod or prevent seed from germing but shouldn't cause any fertilizer issues. Dithiopyr is dimension when you're checking labels

As jc411 mentioned earlier the active ingredient in Lesco 0-0-7 is pendimethalin. After doing some research, it looks like pendimethalin is hard on the roots and might cause staining. I guess better to go with a Dimension based pre-em.

I always recommend using whichever you can get consistently from a local supplier.

Check your local SiteOne, they typically have multiple options. If you're not opposed to spraying instead of spreading a granular, a 5 lb jug of prodiamine for $60 will probably last you 20 years. But you will need a decent sprayer.

Thank you for the suggestions. j4c11, I am hesitant to use the sprayer and know it will turn out cheap. I am trying to stick to organic but looks like pre-emergents are never organic except for corn-gluten which costs $$/lb. I was reading that pendimethalin can cause lung cancer and contaminate water on the long run. Any thoughts on this or organic alternatives? Eventually, I would like to have a lush growth and not worry about weeds but my lawn is not at the best right now. Another issue is my lawn is probably 2000 sq feet (including shaded areas), given the size of a lawn and if I bought a 50lb bag once opened how do you store it? Do you guys have a air-tight container or something? I would hate for my garage to smell like a pre-emergent.

There is no organic pre-emergent - CGM is ineffective in that regard. It will only fertilize the weeds.

Will go with lesco 0-0-7/Dimension and hope for the best. If it takes a year or 2 to control the weeds and then hopefully with regular fertilization, the Bermuda will outgrow the weeds.

Dimension is an excellent pre-emergent. Pay attention to the instructions on the bag, it may need to be re-applied after 3 months.

Thank you..any reason why you wouldn't choose 0-0-7 (pendimethalin) over Dimension?

Pendimethalin is harder on the roots, it stains and doesn't last as long. I have a jug of prodiamine myself , but dimension is just as good.

Thank you! Definitely staying away from pendimethalin. Dimension seems good but it is really weed-n-feed. Goal is to use Milorganite which I am currently using and then use just a pre-emergent. Any idea what is the NPK composition for Barricade-prodiamine? Was not able to find this info.

There is no NPK in Barricade. It's 100% prodiamine but has to be sprayed. If you're going to go that route, generic Prodiamine 65WDG (on Amazon) is less money for the exact same product.

You can also check your local SiteOne, another member said they have granular prodiamine that you can spread with a broadcast spreader. But I don't know if it's mixed with fertilizer, I've never used it.

If you want pure pre-emergent, the most cost-effective and best overall option is to get a jug of Prodiamine 65WDG and a backpack sprayer. It's a little more money upfront but it will pay off in 1 or 2 apps - the spreadable granulars typically have to be re-applied after 3 months and turn out to be about 20 times more expensive.

Agreed, I saw it on amazon for $60 https://www.amazon.com/Prodiamine-Generic-Barricade-5lbs-ali8056/dp/B004GTQBEK  and looks like I might need 0.36 oz - 0.83/1000 sq feet which will definitely come for years. I am just a bit nervous about spraying something and inhaling it. Once sprayed, if it rains, will it wash away the prodiamine? Also is there a Sulfentrazone based product in Lowes or HD? I might bite the bullet and get the Prodiamine.

Wear a mask if inhaling it concerns you. I believe it is recommended PPE.

Prodiamine works by binding to the soil and forming a "barrier". Thus, it needs to be watered in so a rain after application would be ideal. It will not wash off, and it does not leach, it binds tightly to the soil. It does not prevent seed from germinating per se, but after it germinates it inhibits root development and the weed dies unable to further develop. So it will deplete the seed bank while preventing weeds from getting very far. It's outrageously effective.

Once the seed bank is depleted, you may even be able to get away with not spraying it anymore unless you have neighbors with weedy lawns where fresh seed is going to blow in.

Thank you j4c11..Sorry one last question. Is it true that this has only a 3 year shelf life?

I hope not, my jar is going to last me 25 years at the current rate :-)

I'm on year 3 and I notice no loss of potency. Keep it in a cool dry place and it should last a long time.

Great thank you. I saw this shelf life note in some "off" site...not on amazon though. Didn't want to open another thread but on a different issue...I am having trouble controlling weeds in my rose-bed. It is not really a rose-bed but the previous owners had some plants and I get weeds here and there. I have been hand pulling them. I tried round-up for lawns and noticed that round-up works as long as there is not much sunlight. Any thoughts on how to control these weeds on a rose-bed?

I spray the beds with prodiamine as well when I do the lawn, it greatly reduces the amount of weeds I get. Now pre-emergents only work on germinating seed, so perennials are not going to be affected. Ultimately it depends on the type of weed, some require specialty herbicide, some will need glyphosate. If you have flowers and stuff in there and require selective control one of the other forums may be of more help on how to tackle that.

This prodiamine seems to have very good use on the lawn and rose-beds as well. I have some mulch , so maybe I will need to rake it and spray and then put the mulch back I guess.

For Rose-beds, I can apply Prodiamine anytime right? I was thinking of getting that and spraying the beds mid August and then in Sept10-15th time-frame, apply the Prodiamine on the lawn. I will be applying Milorganite Early September for the lawn as well.

You can apply prodiamine anytime, but do check the label to make sure roses aren't sensitive to it. I don't have roses so I couldn't tell you.

Thank you. Where can I get a good sulfentrazone herbicide ? I thought Bayer had one but I am unable to find it on HD or Lowes.

I buy Bonide sedge ender which is a sulfentrazone herbicide with prodiamine from doyourownpestcontrol.com. They have the 16oz bottle for $15.95.

Here's the one my local Lowe's carries:

https://www.lowes.com/pd/ORTHO-32-fl-oz-Nutsedge-Killer/3827751

https://www.amazon.com/Ortho-Nutsedge-Ready-To-Spray-Killer-32-Ounce/dp/B008RH98PQ/ref=sr_1_1?ie=UTF8&qid=1501864321&sr=8-1

Thank you aluvaboy.

j4c11Great! I know this one is not sulftentrazone based but wouldn't this be as effective as the nutsedge killer ? https://www.lowes.com/pd/ORTHO-Weed-B-Gon-32-oz-Weed-Killer-Plus-Crabgrass-Control/50094178

The one you posted would be effective on weeds but will also injure Bermuda turning it brown. Sulfentrazone will kill just the weeds as Bermuda is tolerant of it.

I agree, dont use the weed b gone with the orange top.Its makes the bermuda turn ugly. It eventually comes back but will look ugly for about 2-3 months.I learned the hard way lol

Ive been using the lesco 0-0-7 for the last 2 years. It does a great job on crab grass but not to good on winter weeds.I plan on switching to the barricade (Prodiamine) but dont like the idea of spraying as I have a pretty big yard and no way to spray it.I do have a hose end sprayer that connects to my water hose but I dont think this way is suggested for applying barricade?

Finally bought the Ortho Nutsedge spray but waiting for some days where it won't rain. I am expecting rain in may be 2-3 hours, the website says Ortho Nutsedge is rain-proof in 2 hours. Is it better to wait and spray on a day where no rains are expected?

RandyMan I think Prodiamine is best used with a spray and not a hose..atleast from what I have read so far. I saw a spray in Walmart for $10 but in Amazon I saw one for $30..not sure which one to get. I have heard cheap sprays can leak the pre-emergent. Anyone had issues with the one from walmart? I think it is called Even-flo or something.

Nutsedge killer is most effective after a rain when the sedge is aggressively growing. It's easier to see it also. I apply the next day after a big storm

I applied yesterday..lets see. Keeping fingers crossed.

I have decided to go with this pre-emergent from Lowes - https://www.lowes.com/pd/Sunniland-50-lb-Fertilizer-with-Crabgrass-Preventer-0-0-7/1000008818

Per Sunniland it has Dimension . The cheaper route is Barricade but personally would like to stay away from spraying something and inhaling it by accident.

Randy Man - Sunniland's 0-0-7 has Dimension. I am going to be trying it for my bermuda lawn and will see if it prevents the winter weeds and Crabgrass.

I will look into it,Thanks for the info
