Docks are the key weed that infect nutrient rich grassland in Britain and Ireland, with research from Ireland undertaken by Teagasc showing that for every 1% of dock ground cover, there is a 1% loss of grass dry matter yield.

With the digestibility of docks up to 35% less than grass, and docks generally avoided in a grazing situation by cattle, controlling this weed is an important part of grassland management.
