JANUARY 2026 UPDATE:
Astrokerb® and Kerb® Flo 500: winter application guidance
With cold and snowy weather conditions in the first half of January, oilseed rape crops are opening up and with bare ground this may bring germination of weeds.
If an Astrokerb or Kerb Flo 500 application hasn't been possible to apply in the autumn, there is still time. Astrokerb or Kerb Flo 500 must be applied to oilseed rape by the 31st January.
Before application, remember to check the weather forecast and individual field conditions, following the propyzamide stewardship guidelines.
Don't forget to view the materials on our propyzamide hub and stewardship page.
If snow is present, before making an application, wait for it to melt, because this can increase potential for run-off. If applying Astrokerb, then wait for the leaves to become frost-free before an application.
For applications that were made in the late autumn, you should start to see Astrokerb or Kerb Flo 500 working on the blackgrass, with swollen stem bases and root tips. Remember it can take up to 12 weeks before symptoms appear.
Propyzamide right rate, right conditions, right time
