HOW TO FIGURE SPRAY RATES BY FL/OZ
Take fl/oz per 1,000 sqft
Divide by the number of gallons per minute
Then times by the total amount of gallons you are mixing into
Example: a product need to be applied at 2.5 oz per 1,000sqft, we are spraying at 3 gallons per 1,000sqft which is the same as per minute when bulk spraying. We have a total of 10 gallons to mix.
We would do
2.5 divide by 3 that equals 0.8333 then we take 0.8333 times it by 10 and we get 8.333.
So we would use 8.3 fl/oz of that product into 10 gallons of water.
Tip: if you found out your gallons per minute of your sprayer you can know how much water you need to treat your lawn. You should be spraying 1,000sqft in 1 minute at a normal walking pace. So if your lawn is 5,000 sqft and you are spraying at 2 gallons per minute. You would 2 the gallons per minute times 5 the sqft of your lawn. We get 10. So you will need 10 gallons of water to mix into to treat your 5,000sqft lawn at 2 gallons per minute.
Tip: you can find out your GPM (gallons per minute) fill your sprayer with water. Get a bucket and mark 1,2,3,4,5 gallons on it. Spray into the bucket and time 1 minute to see how full the bucket got in those 60 seconds. Adjust and keep going tell you get desired GPM.
With this information you can now read the label and mix any liquid product into how ever much water knowing you are using the right amount and will not burn your lawn.

Hey Chadd - I'm not seeing any PDF's. Am I just blilnd, here?
Awesome info. I have sticky weed/Cleavers and Spreading Hedge Parsley (I think) and man, is our St. Augustine a mess.
@andy164501 check the description for all the links and information. If you want a lawn consultation, you can email me at turforganics904@gmail.com
Chadd Thank you Thank you Thank you for your breaking down your system. I've spent many hours watching UA-cam videos and have finally came upon yours. I can't say enough on how much I learned from this video. Thanks again.
I'm happy to hear you are finding these vidoes helpful!! I appreciate the support.
Chazz is back in the saddle again with the videos. Nice 👍🏼
This one is a really good one, too!! Let me know what you think!!
A+ video Chazz. Thank you !
Thank you so much for the knowledge❤
No problem!!! Good luck on your lawn journey!!!
Most lawn care videos on UA-cam bundle all St Augustine grasses together when it comes to weed killers. They should realize that products which may be safe for some St Augustine grasses can be deadly for others like Floratam. Floratam is one of the most popular (maybe the most), grasses in Florida. It is also popular in other parts of the southeast and Texas. When talking about St. Augustine grass, UA-camrs should specifically state if what they are talking about also applies to Floratam. I only mention it because it is hard to find weed killer that is safe for Floratam.
I always recommend checking the label. Because most homeworners don't what grass they have. Everything I recommend is safe for floratam. Because we use these products on hundreds of different lawns, we have used one safes for all different types. These products are safe for all types of St.augustine. I should have brought that up in the video.
Thanks very informative!
No problem!! I'm glad this was helpful!!
Thanks, I plan to try this.
No problem!! Glad I could help!!
good stuff thanks. Any recommendations for dealing with torpedo grass in my st augustine grass?
Unfortunately, not. The best thing is to kill off the area and re sod. But honestly, sometimes, for the work, it's not worth the effort depending on how bad the torpedo grass is!!
Learning a ton from your videos. Thank you. Would you ever consider doing a one time visit to Fernandina Beach as consult to get me set up to do my own lawn? I recently got rid of my lawn care guy and now I have to become the St. Augustine grass expert I was paying him to be. But, the lawn was looking horrible.
Give us a call 904 614 9053 to get more information!!!
Chad, how should I attack a weed infestation in my St Augustine when at the same time I'm also dealing with advanced gray leaf spot and a thin/weak unfertilized lawn? I started with the fungicide which I'm planning to do 3 rounds of different groups two weeks apart. Can I apply the post emergent in the middle of these treatments, or should I wait until finished with the fungus? I'm concerned that I can damage the grass doing the post-emergent if it is already stressed due to the fungicide. My plan is to apply the fertilizer 10-0-20 after completion of dealing with the fungus and the weeds to avoid feeding them. Can you provide me with your advice about my situation and sequence of application, please?
This is some good shit. I appreciate it.
I'm glad I could help. Thanks for the support!!
Thanks for yet another great video. I am particularly interested in knowing when to apply. I understand about what seasons during the year to apply the products but would like to know more about when to apply if rain is a factor 1-2 days before or after application (or even the day of application) or if the sprinkler system is to water the day you apply the herbicides, etc. I never know if applying at the wrong time would make the application of the products ineffective because of these rain and watering factors. Any help on this would be greatly appreciated. Thanks again.
Every product will have their own instructions about that on the label. But a good rule of thumb is that they will need at least an hour to dry. But if heavy rain is expected that day, I wouldn't apply. A light to medium rain after it drys will be ok!!
@@bettercallchadd Thank you! I appreciate the advise. 🙂
Will this product kill cloverleaf weeds? That seems to be my number 1 weed here in NW Fl. Thanks, Chad, you the man!
Absolutely!! All the broadleaf weed controls I mentioned will.
After using dismiss and avenue south how long will I have to wait before I put down Humic acid down
No time at all!!! Those products will not affect each other.
Thanks, Chadd. Another awesome video. Question: once you spray the weeds and let them die, what do you do with the dead weeds? Do they stay in the lawn or do you still have to pull them out once they are dead?
Nope. They will decompose!!
I used the Image Nutsedge killer form Lowes in the spray handle type (not concentrate) and Id say its mixed result on how effective it is depending on how bad the infestation is. The biggest drawback Ive noticed with Image is that even in the spring temps it seems to stunt the growth quite a bit, at least in my lawn (yes I made sure I didnt over-apply, measured and was spot on). I gave Sedgehammer a try in a different area (since this season Ive had a explosion of sedge), and while it may work a little slower it has done a much better job than Image and didnt seem to stunt the lawn near as much. Ill have to see if dismiss is any better, but I was happy with the results of Sedgehammer.
Is sedge something that just exists or is there something that promotes it that I may be doing unknowingly?
We used to use sledgehammer before dismiss NXT. I would dismiss nxt is better and probably the best sedge killer for our grasses on the market.
Sedge is a water weed. Loves wet areas. So areas that moisture sits you are very likely to have sedge. It's almost impossible to fully get rid of in wet areas.
@@bettercallchadd so am I watering too much then? Also idk about dismiss NXT, looked it up on domyown and they wanted $730 for a 60oz bottle and $156 for a 10oz bottle vs them selling a hammersedge, surfactant, and dye kit for $100.
@xr1supra85ba you could be. Low lying areas, shady areas, compacted soil, poor drainage can all be a cause as well.
If that's works best for you I would stick with that. Sledgehammer is still a great product.
Can you make a premix of those ingredients and sell ?
Legally, I could not!!
Any recommendations for unwanted weeds/grass in established ornamental beds? Something thats safe to spray that wont kill common central fl plants?
The best safe, non-selective mix is commercial grade vinegar, dish soap, and salt mixed with water.
@@bettercallchadd Should to a video or short on this! Ive got weeds that pop up in my shrubs every so often. I mad the terrible mistake of using roundup on them and it almost completely killed the shrubs. Was able to recover, but lesson learned.
@@xr1supra85ba good idea. I'll do that!!
What is your opinion about Celsius Xtra?
Great stuff!!!! Just be careful using it in the heat. It's my favorite for spring, fall, and winter.
Chadd - How long should kids and pets stay off lawn after these sprays? Thanks!!!
All products say until dry. My personal recommendation is 24 hours.
I live in South Florida and have St Augustine grass. Can I use “Spectracide Weed Stop for Lawn”? The spray bottle with the purple nozzle? It says it is safe for St Augustine grass? I seams easier to use a product already ready to be used.
Yes, you can definitely use that. It's easier to use but much less effective than any of these products. Give it a try and see the results you get. Make sure not to use too much. You can always re apply later if needed.
Thank you so much!
"
OK i"m in"
Good!!
Does it kill torpedograss?
Unfortunately not!!
Do you patch spray or just hit the whole lawn with this?
Just spot spray!!
Have you tried the Celsius + Certainty combo before? Thoughts?
I personally have not. Reading the label should be a good combo. I can't tell you how hot the mix is because I personally have not used it. Definitely should be no problem in the cooler times of year.
Thank you for your thoughts! Love the channel.
@@Saint_Cuthbert thank you. I appreciate the support.
Celsius w/Certainty is at least in my experience very hard on St Augustine. It's also very effective on weeds (including sedges) which explains it's popularity. I try and reserve it for spot treating areas and go with a low mix rate of the Certainty part. I've determined it's primarily the Certainty in the mixture that causes the stunting and chlorosis because when I use Celsius alone it does not cause nearly as much significant yellowing and stunted growth. If you need to zone spray the entire st aug lawn I'd stick with Celsius alone and if you also have sedges just add some Sedgehammer into the mix or just treat the sedge areas separately with Sedgehammer.
Great video. BUT now I have to measure my lawn to know how many thousand square feet I have, bummer!
You can do it from Google Earth. I made a video about on my channel. They have a measuring tool. Quick, easy, and free.
First of all, thank you for the video. You mention that your sprayer will empty the whole gallon in one minute. It took me 5 minutes to completely empty 1 gallon of water. I was not able to adjust it to go any faster. Does this mean I can get 5000 square feet out of my 1-gallon sprayer? If this is correct and the amount of product needed is based on 1000 square feet, then I just need to multiply the amounts by 5 (if I plan on mixing with the whole gallon), correct?
I measure out 1,000 square feet in my driveway. Then I spray it with water to determine my application rate, based on my walking speed and the equipment I am using. I have found that I typically use 1.333 gallons to cover 1,000 feet. Calibrating your equipment like this is the most effective way of determining coverage rates. Over time the rates will change based on the condition of the equipment. Therefore I calibrate frequency.
Thank you
Technically, yes. The comment above gives great advice. I still recommend mixing at the one gallon a minute rate because like the comment says your spraying can be inaccurate and conditions change. If weeds are not dying, then mix a little stronger until you get results.
Chadd, Using your mixing formula, is it correct that my backpack sprayer that sprays 0.5 gal per minute should receive 2.2oz of Avenue South (low end) per 1 gallon of water? This is what I did, but ended up spraying 1.89oz/ 1000 sqft, which is the top end of the recommended 1.1 to 1.8fl oz per 1,000sqft. I used dye, but I guess I may have overlapped? @@bettercallchadd
If you want accuracy on that small of an amount of product, wouldn’t it be better to buy a digital scale?
You could. They have small measure cups that work as well.
Neither Celsius or Avesouth can be purchased unless you are a licensed applicator not for the do your own regular homeowners
100% wrong. Go to domyown.com. you can buy everything an applicator can from there and many other websites. You need a license to apply the product for hire. You don't need it to buy the product or use it on your own lawn.
That’s incorrect I have purchased via Amazon and multiple local stores
Curious why you don’t mention centipede very much?
It's not very popular in the coastal areas where I am located. I will be spending more time this summer on the channel and will definitely be getting into more grass types.
@@bettercallchadd I am in southeast Alabama, and that is the primary turf in my area.
@sidneywhitaker9972 I'll have some more centipede videos for you this year!!
@@bettercallchadd what part of Florida are you at?
