Rotting seeds

Why does wheat seed rot but blackgrass doesn’t?

It's a punishment to the wicked.

If only the breeders would make wheat as hardy as blackgrass!

 

[Wombat]

If only the breeders would make wheat as hardy as blackgrass!

They wouldn;t sell any again if they did............................... similar with disease resistance.....................................

Evolutionary pressure.

 

[Bogweevil]

@Sharpy is in the right of it - blackgrass has evolved to go into more or less dormancy when shed. Some at least of the seed sits in state of suspended life until it loses its dormancy typically a function of time and temperature. More here from the hated AHBD on grass weed dormancy: https://ahdb.org.uk/dormancy-in-grass-weeds

Dormant wheat would be annoying - you sow a field and who knows when it will emerge. Actually this is true of quite a lot of growers on TFF with or without dormancy of course - who knows when or of their wheat will ever appear - it is mystery. Wheat has some dormancy to help prevent germination in the ear but not enough to prevent rapid and even emergence after sowing.

Blackgrass is a marshland plant, it loves wet conditions.

 

[Bury the Trash]

the type of husk (oats grass seed) helps them get a bit of oxygen at a critical time when the likes of wheat just drowns.
and basically its in their genes as above.

one achievement I’m proud of is retiring from a farm that didn’t have any black grass .
Shame I couldn’t say the same about wild oats

Blackgrass has a differing survival strategy. It's only an annual but produces a lot of seeds and spreads them all around. The wetter the better as that way it has less competition.

One day a strain will emerge with tolerance to glyphosate and then it will be a seriously big deal.

I believe it is also known as "Marsh Fox-tail" by some.

been using glyphosate on bg for 30 years still as effective as it was
the only tome it struggles is if sprayed in may before it flowers
2 leaf bg does not need a very high dose to kill it we all use robust doses

i am always on the look out for any signs of resistance
some weeds do need high doses thistles and rosebay willow herb couch grass

Yes but there is ryegrass in the world resistant to it and blackgrass seeds far more prolifically than ryegrass.

But is the rye grass gene in blackgrass
if it was we would know a bout it by now most farmers and agronomists that are any good are constantly watching for resistance
took the other herbicides 10 years to fall to resistance
the gene also needs to not give bg a disadvantage such as frost tolerance or increased susceptability to current pre em

not saying it could not happen but the longer we go on the less likely it is

there are other grasses that take a big dose red fescue tussocks ect

rye grass also susceptible to other newer preems and contacts with different moa

I had some s23 that took 20 years to sort then antlantis sorted it in one season

It's a gene, it's not a 'ryegrass' or a 'blackgrass' or anyone else's 'gene'. My point was that genes for glyphosate tolerance are already out there in the wild- nature invented them. And given that a single blackgrass plant seeds far more prolifically than a single ryegrass plant meaning it will evolve far far faster than ryegrass potentially could. Blackgrass is also a hardier plant that is more readily able to live in the wild or in non-crop areas. Ryegrass doesn't tend to persist in such areas.

With this in mind it is logical the blackgrass would evolve a tolerance to a given herbicide eventually, but close stewardship of the remaining actives will help prevent this.

I think ryegrass produces as much seed as blackgrass, if not more.
