Black-grass control does not start with a pre-emergence herbicide. Doing everything possible to reduce the weed population before you drill a crop is key, and it means making good management decisions right from the off. Below is our guide to managing black-grass from harvest to drilling, starting with six general principles.
There are three main cultivation strategy options for black-grass seed management after harvest.
Match cultivation option to the field situation - soil condition and type, black-grass seedbank and crop all need to be considered.
You’ve decided your strategy and what you want to achieve in your system. Now’s the time to make sure your machinery is set up correctly and won’t bring any unintended problems.
Black-grass favours wet areas, and compacted soil layers can prevent water moving through the soil profile to drain away, so it is important to take steps to avoid and / or reduce compaction whenever possible.
Too much or too little moisture can bring their own challenges, but it is important to manage it to successfully allow cultural control techniques to work effectively as possible.
At harvest, deciding on how you will manage straw from the previous crop can be an important step in setting up what cultivation strategies might be open to you and appropriate.
Obviously a key decision on the farm, and also for black-grass management. Good choices can make a major difference to successful weed management.
Black-grass control is the biggest agronomic challenge facing most UK arable farmers.
