Spray Cocktail - Is it ok to mix these things together in one app?

Hey everyone, I hope you're having a good growing season!

I have a few things I really need, and would like to, blanket spray with my boom sprayer. These are as follows:

Liquid fertilizer (13-1-2)
Liquid Iron (Southern AG Chelated)
Spectracide Triazicide Insect killer
PGR (T-nex)

Can, and should I, mix all of these together in the same tank and spray?

Although it's important to mix the correct rates of all 4, I think the PGR is the most important, correct? For my Yukon Bermuda, I've had good success with a pretty high rate- 0.4 oz/1k sq ft. The label says however to go lower for my Zenith Zoysia- 0.25, so I'm thinking 0.3 might work ok for both?

Any help would be greatly appreciated.

Thanks!

I think you'll be fine, but always worth the shot to put some in a jar and see if it separates. I don't see anything there that looks unusual.

Can you not just do the correct rate for the zoysia, and then add back more to the mix to finish your bermuda? Or are they all blended into the whole yard?

.4 oz seems super high but if your grass tolerates it, then sounds good. If your zoysia hasn't had it regulated before I would be leery going high at first but that little amount may not be noticeable, especially if you are good about not huge overlaps in spraying and are pretty calibrated on speed/flow.

Ok thanks for the input!

And yeah I can try doing the zoysia first, then adding some PGR for the bermuda, that might be a good idea.

And yes I know the .4 seems high, but it worked like a charm last year on the Yukon, as it seems to handle very high rates. I didn't use it on my zoysia because I was trying to get it to grow in from seed.

As far as overlapping, I feel I'm pretty decent at that, considering I always using Lazer dye.

I'd say you shouldn't have any issues spraying then. I would dose the PGR separate, just to ensure no issues. It can be touchy at first obviously you are aware, but after a while I've found you can drift around your target application with pgr and not see too much change.

I am planning on using T-nex on zoysia soon as well for the first time, from what I have researched, zoysia is the most sensitive of the warm season grass to PGR, I plan on spraying at .2 oz/k.

saw a youtuber do combination of fertilizer+iron and T-nex worked well for him, just not sure about the insecticide.

keep us updated on what strength PGR you use and how it turned out.

Only issue I can possibly see....

fertilizer, insecticide, and iron all do best getting down into the soil. PGR, if i understand correctly, is absorbed through the leaf? If this is the case, I'd separate the applications. Do the fertilizer, iron, and insecticide, water it in, then go back with pgr.

Obviously YMMV, but I think with the right tip you can accomplish this with one spray. I do everything above, but no fertilizer and I used a Bifen XTS for the insecticide and usually with fungicide too.

I use a Teejet thats a slightly larger droplet, to allow better soil, but with tightly mowed turf, it's all going to get on the leaf before it finds soil so I've never been overly concerned with the soil/foliar issue in the past. The soil stuff will get in after you irrigate, regardless.

I could see how this could be an issue so pretty good point to consider.

Your explanation makes a lot of sense. I use a hose end sprayer, due to property size, so I tend to think in terms of foliar vs soil when I mix up cocktails.

When it comes to bourbon, it's either neat or the bourbon isn't good enough :)

Yeah valid point @Darth_V8r. Since I'm not more convinced I have grubs than I do chinch bugs, watering-in is probably smart. However, neither liquid fert, iron, or PGR requires it, as they are both absorbed foliar.

It looks like I will be spraying insecticide first and watering, then the other three together.

Thanks everyone.
