Winter wheat post emergence sprays

[jwhatty]

As part of a college assignment we have to create a crop protection plan for reflection WW. Thoughts so far would be using Liberator at 0.45L/ha as post-emergence as the crop is in Shropshire so BG is not of concern more focused on BLW. Any thoughts or suggestions to alternations would be appreciated.

We used 2L/H Tower http://www.adama.com/uk/en/our-solutions/herbicides/tower.html

 

[jwhatty]

Do you have a rough price for that?

Cheers

£109/10L =£21.8/ Hectare

My first question would be what are you wanting to control? You've told us your not n a black grass area, but not what weed pressure you would be under.

Very unkind giving you Reflection to work with

 

[jwhatty]

Mostly broad leaved weeds so mayweed, cleavers and chickweed. Small bit of annual meadow grass aswell.

If no blackgrass, then there will be cheaper options that liberator. Liberator may be used in a blackgrass situation, therefore it has the price to match.

If you have cleavers, then you may well find yourself going back in spring to clean them up.

So going cheap and cheerful in autumn with PDM (maybe some picolafen in there as well).

When are you drilling it? What soil type are you on? Ploughed or direct drilled?

Late drilled might not get any autumn herbicide. If on light land where the wheat will struggle to survive winter, then some people prefer no herbicide so that the crop isn't stressed more than necessary.

Shropshire soils after potatoes and it has been min tilled before drilling on the 7th October! Im thinking of going along the route of cheap autumn post emergence then a spring application to clean up any remaining weeds

 

[Grass And Grain]

If using chlorotoluron check to see if it is approved on that variety. Some aren't.

 

[jwhatty]

Reflection isn't approved post - emergence on tower which is a pain

I think that is the way to go.

Then in spring (presuming you have cleavers to clean up) you could go with starane. Alternative use Broadway Star, which does cleavers and wild oats and brome and ryegrass.

If you have cleavers and wild oats then BS would work out cheaper than using topic or axial for the wild oats and then starane for the cleavers.

What is your following crop and how will it be established. Probably wheat or barley, so that would be OK.
If using any dff, then it must be cultivated to 15cm before the next crop is established (if oilseed rape for example).

Just got to find out some prices for Excalibur and Quirinus now!

 

[Grass And Grain]

You'll also need to do everything you can for yellow rust. It used to be reasonably resistant, but has broken down to rust in the last year or two. Is the seed dressing for rust still available, or was it's last year of approval last year? Can't remember, you'll have to look that up. Fluconconazole I think it is.

 

[jwhatty]

Any help finding the prices for Excalibur and Quirinus is greatly appreciated going to put on as an autumn post em

 

[Shutesy]

Quirinus £216/5l, serviced agronomy though.

 

[Grass And Grain]

I should say @jwhatty that there will be people on this forum who are much more knowledgeable than I am on herbicides.

 

[jwhatty]

Cheers @Grass And Grain going to sort out rates now! keeping them as low as possible as weed pressure isnt too high

 

[Grass And Grain]

Some would say keep chemical rates up to prevent resistance developing.

Not straight forward is it!
