Black-grass trial highlights need for flexibility in broad-leaved weed control

In the spring 2016, Bayer worked with Cambridgeshire grower Paul Drinkwater on a herbicide trial to understand how broad-leaved weeds control could be maintained while effectively tackling black-grass.

The trial became a study into how to maintain the flexibility needed to adapt to changing situation while achieving desirable control of broad-leaved weeds and limiting black-grass seed return.

Watch the video below with Paul Drinkwater and Edward Hagues who discuss the herbicide trial and the lessons it provided.

Black-grass Trials Conclusions

  • On mineral soils it is most effective to use 500g of the 1kg ethofumesate allowance pre-emergence to target black-grass
  • This means careful consideration should be given to post-em weed control options to stay under this limit.
  • Products, such as Betanal maxxPro, can be used that have a lower ethofumesate loading.
  • If black-grass population are high the graminicide timing should be prioritised.
  • Larger broadleaved weeds may then result from observing the recommended spray intervals.
  • By sequencing with the most robust, flexible herbicide control of these can be possible.
