fss from a roundupped crop ?

[SilliamWhale]

I wouldn't

 

[Clive]

Will be fine, never had a problem

 

[tw15]

Have used roundup treated rape seed to finish a field no difference at all .

 

[64farmer giles]

What effect is roundup supposed to have on the seed?

 

[tw15]

Kill the germ or may effect the vigor but not always ,that's about it .

 

[franklin]

Always grows here.

Malting would have been tricky if it caused a problem....

 

[Oat]

If moisture is below 30%, it's supposed to be ok. If unsure do a germination test before drilling, or leave an area unsprayed

I and many others spray malting crops with it 2 weeks before harvest every year without any germination troubles and with malting your require 98% germination to make the grade. Seed you buy only needs to be 85% germination so I'd say it's unlikely to be much of an issue for FSS.

 

[Barleymow]

Hasn't stopped my rape volunteers from germinating

 

[T Hectares]

Never had a problem yet.

Although I would consider you mad to plant any without performing a rudimentary germination test... Which will answer your question and eliminate guess work !!

On malting you just need it to germinate and not much beyond that - on seed you need it to germinate and go on to produce a healthy seedling.

Round Up/Glyphosate on plants where the grain is not low enough moisture can cause 'abnormals' which is seed that germinates but produces distorted seedlings which of course may not go on to produce a healthy plant.

So absolutely get a proper germination test done if you do use Glyphosate. That is why we don't allow it on seed crops.

Good advice , thanks Bazza.

Would that be a low vigour seed then

 

[beltbreaker]

If in doubt grow 100 seeds in peat to see what grows or send it to a seed testing lab who will do the same telling them it has been roundup-ed.

[Tompkins]

Had some Glacier barley tested that had been sprayed off, came back 99% germination. It's now in a bag with red stuff on it!!

Not necessarily the same thing though an abnormally growing seedling may well show up as low vigour. But a low vigour seedling can have normal growth just not do it very quickly. If that makes sense?

[farming4profit]

or

negative geotropism - Glyphosate can produce abnormal rooting where the roots go against gravity and grow upwards. If the seed is drilled deep enough then the plant will still be able to gather nutrients and moisture, but its not an ideal situation to be in !!

whats the reason for using glypho on a bit to be used for hss? if its to hasten ripening/reduce moisture then dont do it for the risk of seed damage, if its to kill grass weeds etc dont do it as you will only be sowing weed seeds with your hss however good the cleaner is ,better not imo
