I live in south central Mississippi and I gave it a try. After 7 days with no rain it was not doing anything. I watered on day 7 and started seeing great results after that. I guess you have to be patient. Thanks for your videos.
@@CentipedeCentralLawnCare The altrazine got the majority of the weeds. I have a bag of fertilome weed and feed 15-0-15 that I bought when I thought the altrazine was not working. Can I use it when I fertilize or should I use Fertilome 15-0-15 fertilizer?
If you feel like most of the weeds were controlled with the Atrazine now then I would probably get the standard 15-0-15 for the first feeding. Then use the weed and feed on the second summer feeding if weeds need addressing
I think I read you're supposed to apply it going backwards so that you're not walking through it as you're spraying. Basically, start at the farthest part away from where your hose is and work your way back towards your house.
I'm in central Illinois. We use 2-4D a lot for turf grass broadleaf weed control. There are a lot of variations and brands for this product. The results are very good. We fight broadleaf plantain (buckhorn), Clover, and Dandelion. I was attracted to your video because crabgrass is the worst threat to our sod. It shows up late in the growing season, and I've been searching for a way to prevent it from emerging. Thank you for your video! I'm going to try it.
That weed and feed is a good product. See what kind of results you get and then by around Memorial Day if you are still having a lot of issues you will be ok to put down the Atrazine. Thanks Timothy
Great video - thank you! Atrazine has done a great job so far this year in my centipede. I have a few spots here and there, but the blanket app really helped. I just got a bottle of Celcius to use when the temps really heat up in the coming weeks.
Thanks Patrick! I am debating on getting some Celsius. I have some available right down the street. I may need it for a troublesome weed I usually get in June.
@@kylescottjohnston I used Celcius just a few days ago to spot treat some spurge in my yard. It's already turning yellow. I used the medium rate in grams per the label per gallon of water. Great stuff for the very small amount that was used.
Great video bud!! I can definitely testify to atrazine working. My lawn is sitting pretty good right now compared to last year when I knew nothing and did nothing. Im in SC and after applying barricade dg in early/mid February and blanket spraying my whole yard in mid March with atrazine, the only weeds im seeing are a few dandelions and some cudweed the atrazine must've had no effect on. I will say tho I've noticed lots of bare spots where weeds once were. I'm hoping the centipede fills in once I start adding iron and the Andersons 16-0-8 come May.. Thanks again for your videos they're very helpful and informative.
You definitely do not see them mix atrazine 8oz of herbicide to 2 gallons of water. You use 1.5oz per 1,000sq.ft. with a minimum spray rate of 1 gallon of water per 1,000sq.ft. This is why product labels and proper training are important.
Good product but you have to be careful with it. The particles are really small and it’s almost 30% Nitrogen so you need to make sure you aren’t putting more than 2 lbs of product down per 1000. Any more than that and that’s too much N for centipede
Yes that’s right. Hopefully no water on it for at least 4 days, but then rain or water after 7-10 days is necessary for the pre-emergent barrier to be established. Thanks!
@@CentipedeCentralLawnCare Thanks! Weeds completely take over in one area of my backyard. I am going to get this spray type weed control and apply it this Sunday. I live in panhandle area and it says there will be four days dry weather starts Sunday.
Check out my Fall Lawn Care video where I discuss the negative effects of Pre-Em that I experienced. Around the 6-minute mark of that video I start discussing it. Thanks for watching!
I applied Atrazine pretty heavy ....2 months ago then again 3 weeks later it took care of 70% of the weeds the lawn looks a ton better... still see some sandspur weeds coming mostly from my untreated neighbors lawn ... should I go back and hit it again with the Atrazine. 10 days After the second application of atrazine I sprayed Ferthome lawn food plus iron 24-0-4... it’s coming slowly like you said it takes a while to see results but I see it coming . What else can I do to get rid of a few yellow spots and get it stronger. Can I or should I add more feed and should I add seed . I have St Augustine... thanks for your utube help
If I’m understanding you correctly , if you have St. Augustine and have only fertilized in March then now would be the time to fertilize again for sure. It likes Nitrogen more than Centipede and should fill in over time via the stolons. St Augustine doesn’t have seed. I would probably hold off on more Atrazine for a while since you have done 2 apps already and maybe look for a broadleaf weed killer safe for St. Aug. Thanks for the comment!
Hi, I hope you can help. I have a centipede yard that is covered in weeds. It is almost mid-May here in NC. We have been gone for months and didn't apply any pre-emergent or fertilizer. It is almost mid-May here in NC. What do you suggest to get the yard back going. Aerate, Fertilize first and then add Celsius/Atrazine? Or, would you suggest something different? Thanks so much!
I would take care of the weeds first. Try Atrazine first and whatever weeds are still present after 2-3 weeks you can take care of with either Celsius or Fertilome Weed Free Zone. After the 2-3 week mark then fertilize. Aeration is great practice but do the weeds and fertilizer first. Aeration can toss around weed seeds and make the weed problem worse. Thanks for the comment.
Great info! How do you know how much you applied since it is a sprayer? In other words how do I know I didn't under do it or over do it based on my 1k square feet area?
I really go by feel and try not to overthink it. Walk at a steady pace and lightly coat the area as you’re moving. You could always get a concentrate to be more precise and measured
Thanks for the info. I applied fertilome spray 2 weeks ago. However, there are still weeds like clover. Do l need to apply atrozine these days if the weather permits or do l need to give more time to fertilome to do its job?
That’s interesting. I would probably give it another week and then you will be fine to apply atrazine. After that I would wait a while before applying any more herbicides. Thanks for the comment!
You can apply now before green up phase but stay away from applying while the lawn is greening up. So you could apply now or just wait til after it totally greens up
Now that we’re getting into the heat of late spring here in SC, what product would you recommend that can withstand the temps? I used (before I knew better) Scott’s triple action for southern lawns, but did so prior to a large rain event and pretty sure most washed away.
Any of the fertilizers I recommend in my fertilizer videos will work well. Also the weed and feed products I recommend in the Weed & Feed video. Links to products are in the description of those videos. I’ll do a summer fertilizer application video late June and possibly do an organic option. Thanks for the comment!
Can I use this now? I have a new yard and i want to treat for existing weeds. I have already used a preemergent for weed seeds so what would you suggest for existing weeds if I can't use the atrazine?
Depending on where you live. You can try it now but if you get cooler temps it may take a while to take effect. Warmer temps it will work better. Fertilome Weed Free Zone works well in warmer and cooler temps. I did a video on that product last winter.
any suggestions for hairy crabgrass? Unfortunately we had a bare spot completely taken over with it and its now starting to spread throughout parts of the yard. Atrazine has no effect on it.
Celsius would be the best. Link in description. Also, Tenacity is a herbicide that is supposed to do well on crabgrass in centipede lawns. I haven’t tried it myself but it’s supposed to be good stuff. Check out domyown.com for it.
I applied Roundup for lawns in mid-March before I started watching your videos. I put down the Anderson's Humic DG early April and I plan to use Anderson's 16-0-8 w/Humic DG Fertilizer early May. I bought this product with Atrazine to try it out, but I'm wondering since I spot sprayed Roundup already if I should hold off on applying Atrazine until later in the season?
It’s really up to you but if you feel like your lawn needs to clean up some weed issues now you can do the atrazine now and then when you fertilize in May the lawn can take off. Then maybe let the lawn rest from the weed killers for a little while.
@@CentipedeCentralLawnCare Thanks for the reply. I do have a lot of weeds I'm dealing with right now, so I wanted to make sure I wasn't going to damage the lawn with this application. Still learning how to take care of Centipede, your videos have been very helpful.
I’ve already used Scott Bonus s weed n feed (w/ atrazine) twice this year on my st aug but I plan on adding this spray in the fall. Should I hold off? If no. what do you suggest as a alternative that I can find in a box store?
Usually Atrazine should be limited to twice per year. That’s what the label states. For second question It depends on if you are using to kill existing weeds or more as a pre emergent
@@CentipedeCentralLawnCare originally I was using it as a post emergent because that’s what I thought it did. And this fall in FL, I was gonna apply a crabgrass preventer granular followed by this weed stop product to water it in so I’m doing both. But then I read I’m limited to only two applications and I can’t find the reasoning behind it
Check out a fertilome product called grass killer. Contains sethoxydiem, kills Bermuda in centipede. The grass killer name threw me off. Don't quote me thou
Good morning I have been following your recommendations for a while that it is September in Columbia South Carolina what would you recommend I be doing I heard a lot about winterizing I still have a lot of weeds been trying to get rid of them any recommendations what I should be doing in September I appreciate it have a good day thank you so much
It’s too late to feed Nitrogen right now. A potassium feeding or 2 would be beneficial leading into fall. Also a pre emergent as temps fall and grass shuts down. Upcoming video on this
The fact is Atrazine has both pre and post activity. You'd be better served to use it before green up. I worked for the company that invented it, so I know what I'm talking about.
The atrazine bottle instructions warn you to wear protective clothing, boots, and gloves. If you get any on your skin, it recommends rinsing your skin for 20 minutes. It also states to be sure to walk backwards while applying it. Wearing a T shirt, shorts and flip flops is flirting with disaster. You may want to consider taking down this video so that others who don’t read the directions aren’t mislead.
The real question is, does anyone know the right answer? I watered mine in yesterday, then i watched your video. then i was confused found this on aa google search, huh. Does atrazine need to be watered in? Do not apply more than 4 lb a.i. Atrazine (2 applications at 4.37 lbs product rate) per acre per year. Apply to dry grass. This product must be watered in immediately after application.
What I like to do is apply to dry grass and when I know there will be no rain coming in. Let it sit for 2-3 days so the weeds can absorb the herbicide. Then you want to water it in for the pre-emergent properties of the atrazine to take effect.
Read the label. It has specific instructions. It's best if there is no rain for 3-4 days (to kill existing weeds). But rain is desired after 7-10 days to get pre-emergent effect. It can take 4-6 weeks before you see results. You are not to apply more than two applications per year.
