burning back weeds in clover with low concentrate gly?

I've heard of using low concentrate gly to knock back weeks in white clover, which will bounce back. I have hit old plots pretty hard intending to kill them off and been surprised at how much clover comes back on accident the next year. Right now I have an older plot that I don't want to replant from scratch this summer, but do want to knock the weeds back saving the clover, and then cast some no-plow on it.

Is 2% low enough to where the clover will bounce back and thrive this fall? Or 1%?
Thanks
 
I’ve tried it. It works because clover is actually difficult to kill. However, some weeds are hard to kill-ie Lambsquarter. Still, I’ve done it and will do so when I don’t have better portions. Weeds are a funny thing. Not all are useless....Our deer browse on many of our broadleaf weeds. Less so on various grasses. A light dose of gly usually does well on young grass....as does Cleth. It seems the trick is finding balance. The most healthy plots may not be weed free....and you’re not likely to see such plots on magazine covers.

As said on another thread today... don’t do the gly in heat of summer when clovers ,especially WC is under stress. Use Cleth for grass or Imox or similar for weeds. Do the gly mix if needed in May when clover is thick and healthy.

Herbicide application rates by % is a variable rate, the rate should be measured by oz per acre. I usually do 16 ozs. per acre on existing mature clover with good results and I definitely wouldn't advise going heavier than 32 oz. per acre, this being based on powermax which is 48.7% glyphosate. The maximum allowed glyposate application rate of 44 oz per acre will kill the clover.
Probably one of the reasons that I get good results at 16 oz per acre is that I use 16 oz of nonionic surfactant and 48 oz of AMS in this mix, which makes it way more potent on difficult weeds like lambsquarter.

You're right on, don't spray heat stressed clover. There is good opportunity to spray fall clover; in the next several weeks if the end of summer rains have turned clover plantings into lush vegetation is a good time to kill those fall weeds, which are often different weeds that early summer weeds. Spring and fall are the best times to maintain clover.
 
Although they have issues, I’m also having success with gly on a wick to kill taller weeds. Sadly, this isn’t help for some low growing weeds. I tend to use a combination of weed wick and mowing when weeds blossom or particularly, as seed pods begin to appear. My experience with a light dose of gly is it will kill many weeds, but won’t even slow down others.

I nearly always took care of my weeds with a mower and/or Butyrac. I never was brave enough to put gly on clover, although I’ve heard or read that it works.
 
Using weak herbicide can lead to herbicide resistant weeds.
I've done it years ago after reading Ed Spinazzola, but I've changed my mind on that. I try my best to follow the labels.
 
I just don't understand why people do this. You have reasonably priced selective options. (Clethodim/24DB/Imox) "Light" gly still has the risk of killing your clover/etc., so you risk killing your plot, and risk having to buy more seed. The math on the selective herbicide is better than the cost to reseed the plot.
 
Not to disagree, but if you read the Roundup label it will state that it requires three to five quarts her acre to suppress red and white clovers. In my experience I have never been able to kill clover with Roundup unless using in combination with a disk or plow 2 disrupt the root system. Even if sprayed in September in the South as the clovers are coming out of dormancy it will still be in full coverage normally by January.
 
I sprayed a beautiful durana plot the first year of it growing and killed the plot with a low dose. Never again on my clover. There are too many better options than using something that might create resistant weeds. I am replanting this plot this fall.

24db and cleth don't kill clover, and they don't kill all weeds. In my experience, they also don't work as well or as quickly this time of year.

This is an old worn down plot. I killed it off last summer at the end of July with a stout does of gly, and replanted. However the ensuing drought did not break unil November, and the annuals I planted did never sprouted. It was dirt through winter, and then a suprising amount of the white clover came back.
Now we have lot of rain. I mowed this last week. I want kill off weeds which are thick and seed with no-plow. I am in favor of the existing clover surviving. I will possibly restart the clover next year. Just trying to maximize use of the space for now. This abuts another small plot that I annually do in no plow with good success for many years. That was also a failure last year due to drought.
 
If someone is struggling with weeds in clover, there's a new product on the market called "ThunderMax" that really cleans up a clover field.
The reason to use gly on clover sometimes is because it really works. As with all other herbicides, according to the labels if a crop is susceptible to injury from a certain herbicide a test area application should done before spraying the entire field.
Glyphosate is labeled for use on clover at 4 to 32 oz per acre with some precautions, here's how the the PowerMax label reads;
11.1 Alfalfa, Clover and Other Forage Legumes: LABELED CROPS: Alfalfa; Clover; Kenaf; Kudzu; Lespedeza; Leucaena; Lupin; Sainfoin; Trefoil; Velvet bean; Vetch (all types)
Preharvest (Except Kenaf and Leucaena).
USE INSTRUCTIONS: This product may be applied as a broadcast application prior to harvest (except in kenaf and leucaena) in declining stands or in any stand where severe crop injury or destruction is acceptable, Application may be made at any time of the year to control annual and perennial weeds.
PRECAUTIONS: This application can destroy an alfalfa stand and severely injure or destroy other legume crops listed, such as clover.
RESTRICTIONS: Make only one application to an existing crop stand per year.
Maximum Single Preharvest Application Rate (per acre) Minimum Interval Between Application and Harvest or Livestock Grazing; 3 days.
Legumes listed; up to 32 fluid ounces per acre.
Crops listed on this label may be planted into the application area at any time; all other crops may be planted 30 days after application.

Sprayed this plot w 2qts/ac in 2018. Never reseeded any WC. I’m kinda thinkin it never killed the WC. Only made it mad. Done it before w same results.
Clovers love S&M. The more you abuse it the better it performs. And who cares about the grass? Almost a symbiotic relationship. Don’t worry over crappy looking fields. Multicultural is the bomb.

That's a nice looking clover field, and I like that "it only made it mad" statement, because that's about all that 32 oz will do to ladino. It takes a very even application of the maximum rate of 44oz. of powermax with AMS and crop oil to kill an established clover field. Clover roots can reach down to more than eight feet deep, and that is how it survives drought, deep frost, and glyphosate. Cultivation actually works better than herbicide to terminate clover fields.

If I go down 8 feet I’m either mining coal or tapping gas or oil here. Shale and limestone within 2-3 ft. Fun planting trees. Lol

I agree with this, but will always lean towards a selective herbicide. We've had good luck with Imox cleaning up clover fields. The only real exception is nutsedge coming back the next year. We've been moving towards diverse blends in all but our smaller woods plots. The previous white clovers in the plots did get "angered" by the 2q/acre of gly and have come back in most places. (which is fine with me)
 
a week after mowing the plot looks better enough to where I don't feel the need to do any heavy herbicide use. Maybe I will hit it with cleth to suppress the grasses...we've had enough rain so maybe it will be effective
