Which active for grass weed control

[Dog]

which of these would give the best results for grass weed control. Pdm, dff, flufenacet. Half rate of 2 of them or 1/3 of all 3. Does picolinafen do much or would?

What grass weeds?

Nothing bad yet, just want to keep on top of a bit of black grass and ryegrass on some headlands. In wheat and barley.

Personally I would be using dff and flufenecet, to my knowledge a lot of black grass is resistant to pdm, although don’t see much black grass around here

4lt crystal + dff or 0.6 liberator.
Don’t muck about cutting rates, you’ll regret it long term - esp if only doing a few headlands etc.

So when stacking actives(which seems to be the recommended) do you still use each chemical at full rate.

Do you have an agronomist? Internet advice is worth what you've paid for it

Picolinafen doesn't add much. PDM and/or Defy helps but really the best base is flufenacet.

Pico and pendi are mainly broad-leaved weed products, but will add something to grassweed control. From your list, flufenacet is the main grassweed product. DFF will do both grassweeds and BLWs, but in the case of blackgrass will only add a little extra control. However, with blackgrass, every little helps.

And DFF is cheap.....
