weedany plant that competes for resources with a plant of importance to man and which is therefore regarded as a nuisance. Weeds usually have a high VIABILITY and can use up disproportionate amounts of water, sunlight and nutrients. Where the weed is of a different plant type from the crop plant (e.g. the weed might be a DICOTYLEDON, such as ragwort, the crop a MONOCOTYLEDON such as wheat) selective HERBICIDES are available which are effective against only broad-leaved plants.
