New Leys

Weed control in new sown leys

  • Weeds compete with grass for nutrients and light throughout the life of the crop
  • With new leys, it is vital to get the crop away to a good start, bringing it into effective economic production as quickly as possible
  • The quicker and better a new sward is established, the longer the economic life of the crop

Chickweed

Common chickweed not only competes with the crop, but can also cause problems of palatability and digestive upsets in ruminants.

  • Germinates in both spring and autumn
  • Growth favored by mild autumns, thin crops and moist, fertile soils
  • Most aggressive of the annual weeds
  • Long period of seed production and high seed return
  • 66% of new leys are seriously infested
