Spray compatibility “bucket test”

If it's 200 l per ha then use 2 liters in the bucket and add one hundredth of each chemical and mix. What is the chemical there is people with more knowledge then me on here that will tell you how well they might react but still good practice to bucket test.

I would only use 1l of water in the above example to simulate that you want to get on and will have the chemicals in before the sprayer is full.
Give the first chemical a good mix in the water, and dilute the second a bit, like it would come out of the induction hopper.

Just because it doesn’t go lumpy in the rank doesn’t mean the chemicals are going to work to thier full potential
a good read of the tank mix partners/ approved mixes would be the bare minimum followed by chat With a seasoned agronomist

if a tank mix is not approved on the product label ( a legal document ), then I wouldnt be that keen on doing it . . .
if other people have done it & had success, then a chat with a good agronomist would reveal that
if nonone else has done it, there is probably a good reason . . .
apart from the physical compatibility ( which a "jug" test will reveal ), you also have to be aware of the chemical compatibility of the products involved . . .

when i was on my college placement the bucket test was one of my jobs. Frequently close to double figures of different chemicals in my bucket. Pallets of chemical without a word of english on them. Boron was my favourite every can was a solid lump and a stanley knife was needed to get it out.
That was 35 years ago, these days i wouldn’t think of the idea. If it’s a worry just don’t do the mix it’s too much of a risk.

Nothing wrong with a bucket test, but I’d have a look online at the various labels for what you want to mix. The manufacturer websites frequently have tank mix lists. Yara has a very good list for their trace elements which includes a lot of pesticides too.
The technical helplines are usually good too. They won’t condemn their own products but sometimes there are answers in what they do not say…

I just drain a bit out sprayer tank into a bucket.
Then add chemical I'm worried about compatibility with.
Only one I've had react was a herbicide for weed control in a undersown field with manganese.

Manganese and hormone weed sprays turn jelly
Especially manganese with mecoprop/CMPP

As I found out!
@robbie insists mcpa plus mn is no problem, i've never been that brave

Depends on the manganese. I have an ibc of ‘donkey pee’ that will mix with anything (nearly) and some yara stuff that is more concentrated but you’ve got to be careful. But as @Flatlander said; physical compatibility should only be one of your worries if you’re trying something out of the ordinary.

It is!!! Ally max, mcpa, 3lt liquid mn plus a glug of cu and the same of zn and 5 kgs epsotop has been a staple on spring barley for years.
Have sometimes used 24D instead and thats juts the same.

Would agree with above, I've done a mix with MCPA and manganese before. Just can't remember if it was nitrate or sulphate. Might well have been both.
It's CMPP that you need to be careful with, but of course a lot of products these days are combinations including a bit of X, Y and maybe some Z too. Not often using hormones as much as they once were, though.
Ally + MCPA both at reduced rates is a fearsome BLW combination. Same with CMPP. Used to use SU + CMPP products to get cleavers and big nettles (from roots) out of wheat.

For any YaraVita foliar products or Biostimulants can use the tank mix app https://apps.apple.com/gb/app/yara-tankmix/id1665911386 or website https://tankmix.com/en/
If tank mix isn’t listed you can request it via both and the test will be done and reported back, useful webinar on tankmix service here
