The farmer I saw this evening plunging onwards through the still green-tinged wheat atop a busily.working spraying machine?
Fungal rot(s)?
What is he trying to prevent?

Hi Peter, I believe it's highly likely it's aphids on the wheat.which have become more of a problem as the climate warms. In my garden they are controlled by hoverfly larvae and ladybirds, but there isn't the habitat for these predators on many farms these days. I noticed the achocha I planted was a magnet for hoverflies this year, so plan to plant them again next year to attract hoverflies to the garden, plus it's an unusual veg too.
There is wheat in the field behind our garden it looks quite golden and should be ready to harvest soon.

Not seen any aphids on any of the usual food plants this year yet.
More to the point, "green-tinged" as in ripening, not soft sappy green.

Another possible explanation.
He may be spraying the crop with glyphosate to hasten the senescence, so that he can get it dry and harvested. This is not uncommon practice. Nice, hey ?

Hi Peter,
I imagine from what you say that the farmer was on foot with a Knapsack spray on this back. If that is correct it will not be spraying for Aphid but more likely spraying isolated patches of mildew or black spot with a fungicide.
But there are so many things he could be spraying for.

JB, "atop"
One of the specialist sprayers on four skinny tractor wheels with.a front cab.and the chassis.rails high enough to (sort of) clear the wheat, boons about fifteen foot each side.

Spraying this late, i think it might be for black point, if so, the wheat will probably be going for bread making.
I don't suppose we will ever know.

Very true OH, I was hoping for replies from our members with farming experience. 
Tony's reply opens an area I was blissfully ignorant of.
Yours intrigues me, what is blackpoint?

Blackpoint is a fungal disease that affects the grain, but i think instead of lying in the wheat fields, i should have taken more notice of what they were doing, as i'm not so sure there is a spray for it.

For more details about pre-harvest glyphosate application to cereals, see the HGCA info sheet:
http://www.hgca.com/publications/docume ... _final.pdf
In summary, once the cereal is below 30% moisture content, you can spray with glyphosate to kill weeds, which aids harvesting, and possibly speed the drying of the crop a bit. Do it earlier and you loose yeild by killing the crop.
Organic bread flour may now seem more appealing ?
