We don't spray a lot of fungicides, only when it's needed. Was wondering about what to do this year. We have a fair bit of damage to our barley and oats this year from wind and a little from frost as well. I'm wondering if it's worth doing some with our herbicide application which will start here shortly. Is it worth doing it this early or is it better to wait and do it at flag leaf? Have looked it up and it sounds like I'd be better to wait as some of the trial showed little improvement doing it early, but not sure if those trial had plants with leaf damage to make it a fair comparison. We used to mix some in with the herbicide years ago but never really did any trials to see if it worked. The cereals look good and finally got a half inch the other night and supposed to get some more tomorrow, but then up to mid 30's by the middle of next week, humidity has been really low so far this year so nothing really pointing to it being a bad year for disease, but we all know that can change. What do you guys do?

Don't really have experience with barley/oats or super early fungicides other than we used put a little in with the herbicide years back like you. But we've done some trials at flag leaf in wheat and it has proven to get us 5-10bu, last year with almost no rain after spraying it still did 6bu better. We're now just budgeting in a pass at flag, some neighbors talked about trying some with their herbicide this year but don't know if they did. I've heard that a flag leaf pass in oats is the ticket too from some neighbors and our agronomist, but I haven't grown oats in a few years so can't speak from experience.

Spray oats at flag. Only problem with this is the straw never dries up. Have to swath. Last year I put prosaro xtr on my barley at flowering on one quarter and the other half got a half rate of quilt at herbicide. There was no fusarium as it was dry as can be and not sure it helped. I belive it was a waste of money. That quarter barely made 80 bu/ac. The other half a half mile away went over 100 bu/ac. It was a much healthier looking crop. It also had a second pass on the flag leaf (around 40ish ac) which yielded no better or looked no better. I believe the quilt helped with drought tolerance as well.
I'm now putting half rate of quilt on all barley at herbicide and only spray for fus if conditions call for it. Save a pass and no tracks in the crop.

Only spray early if it's really wet and good conditions for disease to spread up the plant, fungicide won't fix wind or frost damage.
I seem to remember the penultimate leaf being the most important with oats.
Adding fungicide in hot weather will heat up the mix, especially Quilt has a very high surfactant load so be careful.

I just apply half rate pivot with the broadleaf weed control and follow up with a full rate sprayed on by airplane at the flag leaf just as the panicle is emerging out of the boot. I think its a good idea for early fungicide control , so you are never in the position of chasing leaf diseases. Its plenty wet now , here in the red river valley so I feel satisfied with the early application.

That is interesting with quilt causing a negative reaction to crop health with a herbicide.

Anyone tank mix’s manipulator with herbicides
Want to do my oats and barley with it.

Used Manipulator tank mixed with Velocity in Wheat. No damage, but the tricky part is the Manipulator timing at the right plant stage. I sprayed it at 5 gallons an acre and at the 4 leaf stage and didnt see a difference with the check strip. I think a latter timing is better. Sometimes you think if you save a pass it will save you money but ultimately its the right timing that will save you the most.

We've tank mixed Manipulator with Velocity on wheat and gone at the recommended Manipulator timing and got great results. Now we're running 1/2 rate Manipulator with the herbicide pass around 4-5 leaf and then another half rate when we go in at flag leaf with fungicide which seems to work as good or better and is much easier to time plus no extra passes for us. Trying to hit the perfect timing with a separate pass for Manipulator can be challenging. Last year we got a good rain followed by warm sunny weather just after herbicide spraying, the wheat pushed so fast that the ideal timing had maybe a 24hr window which happened to be over the weekend. We just got 1.5in of rain with more forecasted for tomorrow then hot sunny weather, looking like the same thing will happen again this year. Separate passes trying to hit the perfect timing is usually the best route, but when pushing cereals I have a hard time trying to time 4 sprayer passes within 2 weeks with top dressing N, herbicide, Manipulator, and then a flag leaf pass.

So this practice would be the same with barley and oats?
