a grain or vegetable crop (such as in lieu of spinach), as well as animal feed in Asia and Africa, whereas in Europe and North America, it is commonly regarded as a weed in places such as potato fields, while in Australia it is naturalised in all states and regarded as an environmental weed in New South Wales, Victoria, Western Australia and the Northern Territory. Potential impact on conventional crops It is one of the more robust and competitive weeds, capable of producing crop losses of up to 13% in corn, 25% in soybeans, and 48% in sugar beets at an average plant distribution. It may be controlled by dark tillage, rotary hoeing, or flaming when the plants are small. Crop rotation of small grains will suppress an infestation. It is easily controlled with a number of pre-emergence herbicides. Its pollen may contribute to hay fever-like allergies. Pest control Chenopodium album is vulnerable to leaf miners, making it a useful trap crop as a companion plant. Growing near other plants, it attracts leaf miners which might otherwise have attacked the crop to be protected. It is a host plant for the beet leafhopper, an insect which transmits curly top virus to beet crops. Uses and consumption Nutrition Raw lamb's quarters are 84% water, 7% carbohydrates, 4% protein, and 1% fat (table). In a 100 gram reference amount, lamb's quarters provide 43 calories, and are a rich source (20% or more of the Daily Value, DV) of protein, vitamin C (96% DV), vitamin A (73% DV), riboflavin (37% DV), vitamin B6 (21% DV), manganese (37% DV), and calcium (31% DV), with several other dietary minerals in lesser amounts (table). Culinary use The leaves and young shoots may be eaten raw or cooked as a leaf vegetable, but should be eaten in moderation due to high levels of oxalic acid. The flower buds and flowers can also be eaten cooked. Each plant produces tens of thousands of black seeds. Quinoa, a closely related species, is grown specifically for its seeds. The Zuni people cook the young plants' greens. Archaeologists analysing carbonized plant remains found in storage pits and ovens at Iron Age, Viking Age, and Roman sites in Europe have found its seeds mixed with conventional grains and even inside the stomachs of Danish bog bodies. In India, the plant is called bathua and found abundantly in the winter season. The leaves
