Wheat desiccation timing

[matttargett4]

I suspect I’m the only one with winter wheat crops with bald patches which since the mid June rain have been sprouting all sorts.

realistically to do much post harvest and try to harvest in some sanity it’s a roundup job, but when do I time it?

the proper parts of the field have grains in the bottom of the ear which are doughy, the tops are too firm to squeeze and and have some bite. The flag leaves are all but dead.

in the poor parts grain has just a little milk, flag leaves are 50% green.

im not looking to rush harvest but I don’t want the good bits to spoil for waiting for the crappy bit.

what are people thinking?

got much the same and I spread some seed on the bare patches third week in March just in time to coincide with the drought of course it didnt germinate till May but now all has a seed head on it and I will do a fair bit of damage to the crop drivng through it as the tramlines have all filled in as didnt do a T3 . got sow thistle coming up in April drilled oats now too, although we needed the rain it has made every bloody weed germinate ,thinking of just cutting the ripe bits and come back later to cut the later stuff bit of ball ache but the whole season has been

You can't farm patches. Walk the bulk of the crop (ie the bits that are the bulk of it), look at the colour of the patch of the stem just below the ear (technical name escapes me) and rub some grains out. If the bulk of them hold a thumbnail print you won't be far wrong.

Pre harvest timing of glyphosate is when the grains are at 30% moisture. You can leave a thumbnail mark in the grains. The stem immediately below the bottom of the ear is called the peduncle. This should have turned yellow.

For an unevenly ripening field, I would try and make sure at least 75% is at this stage or you will reduce the specific weight of the grain as you will stop it finishing.
