Cereal Fungicide

[poorboy]

Last few years I've left an AB line or two off in each field of cereal fung we do. Shows up on the yield map every time.

What kind of yield differences do you normally see? 1-2 bus or 7-8 bus?

It is normally a borderline drought here every year and the few times I have used fungicide it was hard to tell if it helped.

Miravis Neo on my barley 2 years ago did help a lot, but my wheat and canola fungicides were actually less yield due to sprayer trampling.

I have noticed that harvest is later on fungicide sprayed vs untreated.

We've never used scales.
Just the color differential you can apply within your yield maps. So 1-2 bu would be almost impossible to see.
I leave a strip and you can see it. Prove/disprove, every time. Depends on year and crop. I have seen easily 20 bpa in extreme cases in cereals.
Kernel weight is bushels too.
Fung on cereals here becoming common. Peas a must. My experience, canola more hit miss perhaps simply because it's not leaf disease?
Obviously drought a different story.
But we need to do our own diligence.
Couldn't say re later. Makes sense cause it's dead quicker. Some times strips are definitely so.
We are in the bushel business.

Expectation needs to be 5+ bpa minimum because you have to make up for those years in which no benefit is seen. Combined triple digit durum and close to it a number of times and have yet to see even a 5 bus difference. Why do we keep sprayin it? I don't know, must be the same reason I keep putting that red shit on the seeds that gets everywhere and coats everthing yet leave check fields every year and never notice a yield difference.

In for a penny in for a pounding.

[blackpowder]

I get it. And once I felt the same way.
I don't know your conditions or your fixed costs.
But part of the reason we have resistance issues for example, is that for decades we looked at crop maintenance as an expense instead of an investment.
I know what drought is and $5.00 wheat for a generation.
Test everything for yourself on your own farm. Don't play the blame game. Somehow yields have gone up everywhere over last 40 years.

20bpa gain that's amazing I would love to see that. We use scales on our checks.

My biggest reason for fungicide is fusarium, can’t afford wheat to be downgraded to feed or worse.

Sphaerex and Miravis are both good products. Just use what works best for your programs if u are using them.

After pricing fungicides the last few days I have to ask why not forget programming and buy generic versions? Generic Prosaro is roughly 1/2 the price, no amount of programming will make that up. Just my 2 cents.

[Grahamp]

All generics here.

[jamesb]

Doing more math here too . The newer Sphaerex is over $22 before rebate which is supposed to be $5 or $6. Compared this to the old Folicur generic. A tote of Tebbie on sale the other day made it under $4 per acre.

We are in a wet area its just common practise. Its about bushels and if you want a number that's high you cover every base. If you miss one step maybe yu ou don't see a benefit. 1 in 10 you lose the rest are a win win.
