24D Spray rate?

15 posts in this topic

Anyone know the mixing rate (chemical to water) for 2-4-D? I have 2.5 gallon jug of it and the directions wore off. I use just a basic 15 gallon Fimco lawn sprayer. Just need to know how many ounces of spray per gallon of water.

Thanks!

Labels permit rates in the 0.5 to 2 lb ae/A rate (1-4 pints) for broadleaf weed control in pastures. Most applications go out in the 2 to 3 pint/A range depending on weed size and moisture conditions. Dry conditions require higher rates.

What product and how much area do you cover per 15 gallons?

I use 1 oz/1000ft2.

In my 3 gallon back pack sprayer, I use 3 oz of the herbicide.

If you know what you have for herbicide, you should be able to find a label online.

Where did you get the jug of chemical?

That would be a LOT of 2-4D. I don't know where you're reading those specifications but when I broadcast on my small grain the rate is about 3/4pt. per acre with about 10-15 gal. of water per acre coverage.

Fleet Farm

You need to go back to Fleet Farm and read a label then.

Either that, or if you know the brand, do a google for the product and find a label online.

Once you have the label, or the product NAME, not "2-4-d", I can help you out.

You can't really use what numbers people are throwing out because each product is going to have a different percentage of active ingredient.

Also, depending on what you're going to use to spray, you're going to use different amounts. Depending on how fast you're going to go with your sprayer, you're going to use different amounts.

Personally, the equipment I use, I use 50 ounces per 50,000 sq ft. That's about 3 pints per acre.

I use it in 10 gallons of water. If I mixed at 2 ounces per gallon, I would only have 20 ounces of chemical, and be applying at less than 1/2 rate, and wondering why nothing died.

However, if I'm using my spot sprayer to get close to bushes, flowers and trees, my chemical is rated at 3 oz per gallon in a handheld sprayer.

Lastly, I don't mean to be mean, harsh or rude either. I'm just trying to help you out to do the job right the first time, rather than waste an afternoon / evening, and then wonder or worry why nothing died, or possibly everything died, even the grass.

I could post many pictures where people thought they could just do it themselves, and "if a little chemical works, then alot of chemical will work better, right"?

Got mine from the brother-in-law who farms. I usually use 1/3 cup per gallon which seems to be about right.

I have worked with many chemicals and one needs to read the label as LwnmwnMan2 says as they are all different in rates. What works for one weed height may not work for another.

I always cut the rate down when I use a hand sprayer as one can apply a little too much very easily.

1 pint/acre 43560sq ft = acre

24D under dry condition can be a little hot and may damage some grass roots causing grass to yellow if sprayed on too heavy

i assume you are going after broadleaves and dandilions in your lawn remember if sprayed on wet grass the chemical will lift and move as sun warms the ground and kill flowers and gardens

good luck

I have found this to be something you need to experiment with to figure out what works best for your setup and the chemical you have purchased. A decent starting point is 1 oz chemical to 1 gallon of water. Try that, then check in a couple weeks to see how it worked. That's probably the lightest you'll want to go, and you might find that 1.5 oz per gallon really puts the knock on 'em.

1.3 oz per gallon is what I use in my 25 gallon sprayer. Ya need to be careful not to make it too rich, or it can kill the grass too or turn it yellow. I can say that because I have used up to 8oz in a 2 gallon sprayer, but at the time I didn't know any better, and that was a waste of chemical.

With 2-4D you won't have to wait a couple weeks. It's a fast acting herbicide. When I spray my grains in the morning I can see wilting on a lot of plants before day's end.

It's going to depend on the weeds, chemical formulation (percentage of active ingredient) and climate.

I did a yard about a month ago, and it was cool. The dandelions wilted fairly quickly, but the customer complained the creeping charlie was still green and growing.

I went back a week later, the temps had warmed up some, and the creeping charlie had started to turn yellow / red.

I agree 100%. You need to know what the 2-4-D% is before you can tell what rate to spray. There are differnt % of 2-4-D in most kinds of spray so one kind might have a higher rate than another. Best bet is to do as LwnmwnMan2 says and go back to where you bought it from and look at the lable of the same kind you have..

    • nice story, fishing has a way of easing the pains we have. even when we hurt like crazy when done for the day we are looking forward to the next outing.
    • way to go, guys yep, the toms not about to give up even though its close to closing time have seen several strutters the past couple weeks and heard gobbles yesterday while fishing
    • great job. makes it 5 for 5 for team 5 congrats on a nice tom, 57 and that willl give our team score a boost
    • One More Cast      Photo by:  Roger Abraham   If any of you out there are regular readers of my tales, you have followed my recent struggles with back and knees.  I can’t put a name to this drive I have to be on the stream as of late.  It borders on obsession. I guess in my mind if I am healthy enough to fish the world is right with me and I am not getting old and feeble.      Today I was a witness to that I am not the only one.  Lots of anglers and hunters live to go out into the outdoors. .  It is what drives them.  It makes them feel alive.  It is their passion.  I told my fishing buddy Abe today my thoughts.  I told him how I was feeling a little old.  I guess my 60th birthday coming up next month makes me feel mortal.  Abe laughed and said I was a young buck compared to him.  Abe turns 76 this year.     Abe told me tales about catching big trout in tiny streams in Wisconsin and out west.  The twinkle in his eye when he reminisced I had seen before in many trout anglers.      We fished a stretch for 2 hours.  I sat down and rested often.  Abe kept on fishing. He got hung up in a box elder branch and lost a lure.  Abe told me box elders trees were his nemesis when he fished.   He asked me which tree was my kryptonite.  I told him, "ones with branches."  We both had a chuckle and continued fishing.   I thought to myself this guy is really driven.  I hope I am like him at 76.     We got to the vehicle and Abe wanted to continue fishing.  Abe’s waders sprang a leak earlier and he fell in the water a couple times.  He was quite wet.  He wanted to change in to dry clothes before we continue.  Abe peeled off his wet shirt and there were two things stuck to his chest.  He could tell by my questioning look he needed to tell me what was up.     Abe told me he had been having heart problems lately and he was supposed to be wearing a heart monitor.  He left it in the car because he was afraid of getting the electronics wet.  Here I have been whining about being old and the guy I was fishing with left his heart monitor in his vehicle.      Abe reassured me that he was in no danger and he could continue fishing.  I started brainstorming on a place to fish where it was not so hard walking.  Now that I knew he was not as healthy as he looked I wanted an easy place to fish.  I knew the place and it was upstream 5 miles.     We arrived at the well manicured field.  It looked like a golf green.  I picked the area because the farmer kept sheep and goats on the land and the weeds and brush were gone because of the goats.  We walked and fished.     Abe told tales of the old days and of fish lost and landed.  I walked a little forward to fish and looked back to check up on Abe.  What I saw when I looked back scared me and I immediately asked Abe if he was ok.  Abe was laying flat on the ground face down.  I thought the worst and he could tell by my face.  He told me to calm down.  His back was acting up and he needed to straight it out and that was the best way to do it.   We fished a little bit more and he took a photo of me.  He liked the lighting. He told me it captured the essence of trout fishing.  He did not have a camera.  I let him use mine.  He was not camera savvy and needed an impromptu lesson on how to use it.   We drove to his car and we talked about our love of the outdoors. We shook hands and headed our separate ways and promised to fish again soon.  As I drove home I smiled and thought about how I am going to be when I am 76.  I hope I am like Abe and my eyes still twinkle when I talk of chasing trout and I am still driven to make one more cast.
    • The past week has had me having multiple close calls and missing a brute at 45 yards.  Tonight I talked my dad to give it another try and there were birds in the field when we got there.  Birds ended up leaving as we tried to sneak in.  A short 20 minutes later they were back and we watched and worked the big group of toms and hens for more than 2 hours before we got one to commit.  Dad shot him with his 20 gauge at 48 yards,(this thing shoots an awesome pattern).  The 3 year old was down and only flopped a few times.   Nice 1+ inch spurs, 10" beard and heavy.  A good evening for sure!
    • Sorry to disappoint guys, but this tom was not my first bird of the season. Apparently that's part of the rules. The score won't count towards the team. I don't have any measurements for the jake I shot so we will have a zero from me.    At least my freezer is full. 
    • Way to  go 1957 !! Congrats!!
    • sugar is not a drug.
