Clearfield®
Straightforward weed control
A wish list might be a wide weed spectrum, flexible post-emergence timing, convenient to fit around the clethodim spray, and help with blackgrass control.
How does the Clearfield® system deliver?
- Wide weed spectrum? Yes, it controls the common broad-leaved weeds + brassica weeds + volunteer cereals + volunteer rape. There is also observed field activity against ryegrass, bromes, wild oats.
- Flexible post-em timing? Yes. Safe, flexible crop timing (cotyledon to 8 true leaves) and flexible weed timing of 1-4 leaves on broad-leaved weeds and 2-3 leaves of grasses.
- Convenient to fit around the clethodim spray? Fitting in 2 post-em sprays can be tricky but flexible crop timing helps.
- Help with blackgrass control? Clearfield® herbicides will not give adequate control of blackgrass; use your standard programme against this.
Clearfield® herbicide recommendation
Application: Goodfoliar uptake is important. Always include Dash® HC which aids spread and uptake. Achieve adequate cover with 100 litres water/ha and a medium spray. Allow a minimum of 2 hours to become rain-fast.
Rates: Cleranda® 2.0l/ha + Dash® HC 1.0l/ha or Cleravo® 1.0l/ha + Dash® HC 1.0l/ha.
The following weeds can grow away quickly, so we recommend a maximum weed size for application: Crane’s-bill spp: 2 leaves. Runch: 3 leaves. Mayweed spp 4 leaves. Poppy 4 leaves.
Clearfield® herbicides should only be used on Clearfield® varieties (name has CL suffix).
On the non-Clearfield® crops, how do the DMTA-p herbicides deliver?
- Wide weed spectrum? Yes, excellent broad-leaved weed control. Either use it solo or at reduced rate with a possible follow-up of Belkar or Astrokerb.
- Flexible post-em timing? No. But the risk share programme helps mitigate the need for early use.
- Convenient to fit around the clethodim spray? Yes! Plenty of room.
- Help with black-grass control? Herbicides containing DMTA-p remove 50-80% of blackgrass before the clethodim spray, with low resistance risk actives. A multi-pronged grassweed programme is becoming increasingly important.
