Post-em Bgras control
- Thread starter Neddy flanders
- Start date
I believe, that among many factors, cultivator drills have increased the prevelence of blackgrass. It soon became obvious, that along with their ability to deal with trash etc they didn't like it particularly when things got sticky. So everyone drilled earlier and used the dust, only to place massive pressure on herbicides to control early established blackgrass- and the outcome is where we are now.
Firmly believe we will see a switch back to more 'fathers' attitude to drilling these infested farms. Have access to a wide, simple drill that has penetration- tine/disc, have the ability to finish a seedbed directly ahead of it, and drill late.
Whereas that would have been a kkk/powerharrow fb an accord or tive in the 80's, the bigger farms these days may be looking at vaderstad/unipress/kockerling/dalbo wide finishing cultivator fb dale/kv etc. The ability to tread lightly will be paramount, so we will see the prime movers either parked up after primary cultivations, or used to finish the seedbed ahead of a well shod 150-200hp machine. Remember the world record crop of wheat that stood for 20+ years was a second wheat sown in November 1980 in the borders- later drilling doesn't mean lower yields(13.99t/ha I think).
Those without blackgrass will think this is all bull, but there is little point setting an 11t/ha crop in September for it to become an expensive 8t/ha crop at harvest. I think most would rather set a cheaper 9t/ha crop in October and take it to harvest as it started.
The irony is that it will probably be cheaper- and as nothing much is new in farming, become the new 'fashion'!

I would take a 7.5t/ha crop with no BG over a 9t/ha crop with.

Roundup it next week and drill it again a week later as you should have done on such a situation anyway. Might seem mad, but next harvest will prove it right.
I very much doubt it.
Exactly
I actually think that agronomists as we know them have not got long left. The whole farming concept is far simpler than they let us dare to think.
Weed control disease control can be more effectively controlled through simple but good farming practise.
1st throw away the cultivator
2nd throw away the an fert
3 use good nutrition
4 don't farm for cosmetics

If you were to re-drill with winter wheat, would you re-pre-em?

As suggested above would think about contact first then flufenacet in Nov. Need soil surface with a seal of moisture. Gonna switch topik and ctu around for this reason on our w.oat problem areas

Really? Didn't think it was post patent yet
May be parallel inport then. Either way, same active but not from Syngenta.

I used one called Roaxe 100 (? spelling ?)

Or is the theory to make a band half an inch deep beneath the surface (by a rain event) in which germinating weeds are history? Any green weeds on the surface have made it? (my spring beans had lots of purple osr cotyledons, but we're talking blackgrass)
5 Do BASIS & FACTS then make your own informed decisions.
Please explain points 2 and 3?
A
Amonium nitrate uptake can not be regulated by the plant, s if you apply it and it rains it goes into concentrate and as the plant uses water it also has to use the an. Which in turn causes lush vegetative growth and more disease as a result. Check for mildew about 10 days after applying.
Good nutrition at the right time is far better and cheaper. Don't feed your soil for the next 50years, feed your crop for the next 6months. Less nitrogen fert replaced by potassium and phosphate when it needs it will help reduce crop disease pressure and should benefit yield.

Ok, but I'd modify that by saying "feed the soil & it will feed the crop."
Vegetative growth is required to intercept sunlight & turn it into starch/protein/malt/oil. What do you advocate instead of AN? Urea? The kind of Bionature etc tonics that Tim Lammyman used to break the UK wheat yield record? Why not just apply little & often nitrogen - there's no denying that crops require N but AN is a crude yet cheap way of supplying that, as you say.
