Tips to optimise/maximise grass-weed control this autumn

• Use as many cultural methods as possible to reduce grass-weed numbers prior to crop establishment

• Refer to HGCA guide ‘Managing Weeds in Arable Rotations’. Ask your local Bayer contact for a copy or go to www.hgca.com and click on publications

Choose the right pre-emergence herbicide for your grassweed populations

• Know your grass-weed spectrum and resistance status
• Flufenacet is proven to be the best pre-emergence herbicide for rye-grass control
• Use Liberator® at 0.6 L/ha as a pre-emergence in any grass-weed situation.

Apply the pre-emergence herbicide as a true pre-emergence application

• Liberator works best as a true pre-emergence herbicide

• Aim to apply within 48 hours of drilling. DO NOT be tempted to wait for moisture to be present before spraying

• The best pre-emergence performances are from full rates on a fine, firm, consolidated seedbed within 48 hours of drilling

A reminder…. Apply Atlantis WG in the autumn when rye-grass is at 1-3 leaf stage. Why?

Protect yield

• Leaving rye-grass uncontrolled throughout the autumn saps yield

• Any later germinators will be less competitive and can be tidied up in the spring

Gives you the best chance of the very best control

• Year after year the most consistent control is achieved by Atlantis WG applied in November

• Poor performance is more typically associated with application dates in March or April rather than autumn

• Small plants are easier to kill

• Control is better going into a cold period than coming out of a cold period

Get the best from a residual partner

• Residual partners for Atlantis WG give a better up-lift in control levels when applied with Atlantis WG in the autumn

Only use recommended tank-mixes

• Complicated tank-mixes can reduce Atlantis WG efficacy and increase risk of crop effects

• Applying Atlantis WG in the autumn reduces demand for tank-mixing making the application more likely to give good control levels and stay crop safe
