Atlantis WG, Spring 2016: What can it offer?

The problem
With what appears to be another mild winter behind us grass-weeds have continued to grow through December and January. Don’t be caught out by aggressively tillering black-grass by not finishing the job with an effective post-em treatment.
Reducing plant numbers now will not only help avoid considerable yield loss but crucially will also reduce black-grass seed return for your following crops.
Don’t forget!
Atlantis WG is much more than just the most effective black-grass post-em treatment. Atlantis WG also controls:
- Wild-oat
- Annual meadow-grass
- Vol. OSR
- Roush-stalked meadow-grass
- Rye-grasses
- Chickweed
- Mayweeds
Key points for weed control with Atlantis WG in spring 2016
- Apply as soon as possible but when black-grass starts actively growing to maximise efficacy.
- Always apply Atlantis WG at 0.4 kg/ha with 1 L/ha biopower to a dry leaf, ensuring at least 2 hours before rainfall. Add a proven residual partner such as Liberator 0.3 L/ha if subsequent black-grass emergence is anticipated.
- For the most consistent results apply Atlantis WG as a fine to medium spray in up to 200 L/ha of water, at the correct boom height for nozzles fitted and travel no faster than 12kph.
Black-grass control is rarely poor value for money
If just 12 plants/m² have survived autumn residual programmes you risk:
- 5 – 15% yield loss
- If each plant develops 10 tillers and each tiller has 100 seeds = 12,000 seeds returned to the seedbank
- If 60% of these seeds are viable then the potential is for 7,200 plants/m² to control next season
If Atlantis WG controls:
- 80% = 5,760 plants/m²
- 60% = 4,320 plants/m²
- 40% = 2,880 plants/m² you don’t have to control next year…..
Chart shows the benefit of post-em treatments, even on resistant strains
On really tough black-grass outright control from Atlantis WG can be variable. However, the real value which Atlantis WG brings in these situations is helping to reduce populations further after a pre-em has done a good job.
