Wild Oats - Damage

Wild Oats are one of the most competitive of the common grassweed species with similar competitive abilities to Italian Rye-grass and Sterile Brome.  

A population of five plants/m2 typically causes a yield loss of 5% in cereals, but much higher crop losses can occur in severe infestations, especially if crop lodging occurs.  High populations can slow harvesting and, because not all seeds are shed before harvest, there can be considerable contamination of grain and straw, especially in winter barley.
