Butyrac200 or Cleth ?

Is it too late to spray Butyrac200 or Cleth on my Clover plots in VA? They're looking pretty good, the best they've looked in 3 years. If not too late, should I add a surfactant to either of them?
 
I would only spray if you have any weeds or grasses showing up in your clover.

I typically spray my clover plots twice a year....once around late May, and then once in July depending on the grass and weed situation.

No, I don’t feel that it would be too late for you to spray, and yes I would add surfactant.
 
I've sprayed Cleth preferably in mid May up to late June with good results. Or in Sept if needed. And yes def add crop oil or surfactant, I do the former. And add AMS. Make sure you add and mix well the AMS before adding your Cleth. I've not used Butyrac.
 
Butyrac and Cleth are opposites as far as the weeds they target, so first you need to determine what problem weeds that you want to kill and pick the correct herbicide. Clethodim kills everything in the grass family, including corn and small grains. Butyrac kills everything in the broadleaf family except legumes, which is beans and clovers. Mixing both of these together shouldn't be a problem, they're often mixed commercially. You can spray these on clover anytime all summer long, but they will work much better on smaller weeds, so they work best in the spring, or after mowing. You should use surfactant with almost all herbicides, at any time, for a better weed kill. The only time to not use a surfactant is when spraying a sensitive crop such a chicory.

Note; although some people will disagree, 3/4 quart per acre of glyposate also works on clover to clean up some problem weeds, this would be my first choice for spraying later in the summer when there's a lot more growth to deal with, this I would spray on the big weeds a week before mowing.

On Butyrac; There's very few herbicides that can be used for mixed crops, Butyrac has one huge advantage for food plots, it can be used on certain mixes such as oats and clover.

I didn’t want to say it out loud in my post and cause drama as I’ve evidently caused all the gly resident plants in the universe. But I add 8 oz of gly to my Cleth mix. Kills the unwanted , sometimes cause a burn of clover and chicory and alfalfa but they recover quickly.

Are all crop oils the same? Which do you recommend?
They all claim to be the best, I've never noticed much difference. The more expensive kinds have surfactant and adjuvant combined. I often use HotMes, because it's cheap and works good. Buy what your supplier sells, or make your own: Mix 2 tbsp of vegetable oil and 2 tbsp of liquid dish soap with 1 gallon of water.

To clarify terminology, a surfactant is a kind of adjuvant, in simple terms, that makes the active ingredient stick to plant leaves. In herbicide terminology, usually when an adjuvant is mentioned it's talking about an additional additive beyond a surfactant, meaning something that neutralizes the water chemically so that the active ingredient is more potent, such as spray grade ammonium sulfate (AMS), which should always be used with glyphosate, and a lot of other herbicides.
Adjuvants can be very confusing, that's why reading labels is very important, adjuvants will be specified on the label.

I'm pretty sure that I read somewhere that you can't tank mix B200 and Cleth.
I thought I would save time a few years ago so I mixed them together in my tank...what a mess I had on my hands! The mix had thick, slurry lumps all thru it. It would not flow thru the sprayer.

I think it's in the Butytac label..

yep label says to not mix it. I just bought a gallon and that's what I read.

I’m going to give this a shot this week. My grasses are taller now after the heat is starting to pass and more consistent moisture is presenting itself.

Am I better off mowing then waiting a week to spray? Or spray then mow a week later? Or am I to late since the clover is bouncing back after the summer heat and dry conditions to spray Gly?

Is one better then the other? I’m assuming if I spray first, less herbicide reaches the clover since it’s lower then the grass and broadleafs.

The label will tell you ideal sizing on the target weeds/grasses. Read it, and then decide if you need to mow.

Without a doubt the grass needs to be lower according to the label. But I saw mentioned when spraying gly over a clover field people are spraying a week before mowing. So is it ideal to spray gly. A week later mow then a week or two later spray cleth for the grass?

I would not use gly/cleth mix in the heat of the summer. Wait until next May when clover is thick and healthy to use that mix. You can use your Cleth in Sept with decent results but again, don't add the Gly.

I added chicory to our mix this year. I often clean up plots in the spring with clethodim and it calls for a crop oil. Will I no longer be able do that with chicory in the plot? Can you spray cleth without crop oil? Don’t ask me what crop oil I use, the label came off a long time ago. :rolleyes:
 
I know some people talk about needing to use a nonionic surfactant instead of crop oil when spraying chicory with clethodim, but I'm not sure why, I've done it in the past with good results. Nonionic surfactant is relatively cheap if you have any qualms about it.

Our local suppliers have Drexel HotMes nonionic surfactant readily available at reasonable prices. This stuff is supposed to only need 50% to compare equally to crop oil, so at that equation it's actually cheaper per acre than crop oil.
