How much of a weed problem Chenopodium album poses depends upon the crop and the cultivation methods. Its crimes are that it is adaptable and capable of very rapid reproduction. It can grow and create seeds under a very broad range of conditions. When conditions are good, one plant can produce thousands of seeds (500,000 for example). That means that a few plants in the field this year could be a carpet of plants next year, and thousands of little weeds will significantly decrease the yield of any crop.
