Grassland Crop Protection

Grassland management is often overlooked for new leys, but by prioritising weed control early during establishment, you will achieve cost-effective, long-lasting control, resulting in a better quality crop in the long term.

The key is to get weeds under control while they’re just seedlings, to give the new ley a clean start and remove weed competition which can result in gappy swards. Generally, the most effective time to apply herbicide treatments is when the weeds are at the 2-4 leaf stage and once the grass (and clover if present) is large enough to be sprayed. By striking with an early herbicide application, an extremely high level of dock control can be achieved, better than at any other later timing during the life of the ley.

For established swards, the focus is on perennial weeds such as docks or thistles, and on invasive annual weeds such as chickweed. When targeting perennial weeds, it’s important to remember the fundamental principles of weed control:

  1. To kill the weed, we must get a lethal dose down to the root
  2. The weed must have sufficient green leaf area to take up the chemical applied
  3. The plant must be in active growth to move the chemical from the leaf down into the root

Correct product choice, an appropriate rate and timely application are crucial. ‘Clover-safe’ herbicides can be usefully employed. However, when there is a particularly challenging weed problem, it may be advisable to forget about saving the clover and use more effective ‘non clover-safe’ products. It is a straightforward process to re-establish clover at a later date. Early treatment not only allows you to get on top of weeds, but also allows the new sward to get a good, clean start without weed competition, so sown species persist for longer. The approach needs to be field specific in terms of the product recommendations, so talk to one of the Wynnstay agronomists, who can advise on the best approach for you.
