Using high sowing rates to control weeds in wheat locations
Aims

To use a combination of alternative weed control methods to minimise the reliance on chemicals.

Key messages
  • High rates of seed and fertiliser could indeed be a useful tool for controlling weeds. Seed costs would be a little greater but the ability to control the weeds without using chemical - particularly in a situation where resistant weeds become a problem, could certainly make the cost acceptable.
