Chenopodium album is found around the world and occurs on weed lists just about everywhere. While definitely considered an agricultural weed in the United States, I do not find it on noxious weed lists here. Noxious weeds are plants considered so damaging to human activities, especially agriculture, that they are actively eradicated. Apparently cropping methods in the U.S. usually control C. album adequately. Thus, although abundant and widespread, Chenopodium album often is either unnoticed or ignored. It lacks the characteristics that make less abundant plants noxious weeds: spines or poisons or characters that interfere with farm machinery. Its weedy characteristic is to grow fast and multiply. When lambsquarters is extremely abundant it definitely threatens crops. Otherwise it has simply followed us around the world, growing well on the edge of homes and farms and along roadways.
