		Common lambsquarters may be up to 6' (180 cm) tall, depending on moisture and soil fertility.
		Lambsquarter blooms from May to October and produces abundant amounts of pollen.

		Common lambsquarters (Chenopodium album) is a member of a group of plants known as the "goosefoot" genus because of the leaf shape of plants found in this genus.
		Not surprisingly, people once regarded lambsquarters as a delicious wild vegetable, boiling young plants until they were tender or eating them in salads and soups.
		Lambsquarter is an early emerging summer annual; one of the first species of summer annual weeds we tend to notice in the early spring.

		Triazine resistant common lambsquarters was discovered in the early 1970s and is today considered to be prevalent on many PA farms.
		At one location, common lambsquarters control was reduced in the POST 4 application because of larger weeds and interference of the spray pattern by larger corn.
		The noncompetitive vigor of triazine-resistant and a susceptible common lambsquarters also was compared by growing plants in individual containers and harvesting them periodically throughout their vegetative period and at reproductive maturity.

	Science Fair Projects - Lambsquarter
		Lambsquarter, also called white goosefoot, lamb's quarters, fat hen, or pigweed, is a fast-growing, upright, weedy annual variety of the goosefoot, very common in temperate regions, growing almost everywhere in soils rich in nitrogen, especially on wasteland.
		This weed can be a host to the beet leafhopper, an insect which transmits curly top virus to beets.
		Lambsquarter can be eaten as a vegetable, either steamed in entirety, or the leaves cooked like spinach as a leaf vegetable.

	ISU Weed Science Online - Nozzle Perfomance
		The leaf surface of weeds is considerably different than a flat piece of paper, thus the researchers evaluated spray retention on the foliage of both lambsquarter and redroot pigweed.
		Inclusion of either a methylated seed oil or a nonionic surfactant increased dye retention on lambsquarter more than two fold compared to application without an additive, but the additives did not influence dye retention on redwoot pigweed.
		Nozzle type did not effect dye retention on common lambsquarter, but there was greater retention with the Flat Fan and Drift Guard nozzles on redroot pigweed than with the other three nozzles.

		The lambsquarter had a much higher survival rate than any of the waterhemp populations, with 85% of the lambsquarter surviving the 32 oz application.
		Unfortunately there wasn't a 'control' population of lambsquarter included in the screen to see whether the high level of tolerance was due to greenhouse conditions that affected the lambsquarter differently than the waterhemp, or whether this biotype is indeed highly tolerant to glyphosate.
		We did not have additional seed to repeat the study with other lambsquarter biotypes, but are working on collecting additional seed from the field for future studies.

		Larger weeds, including lambsquarters and Chinese thornapple, are not adequately controlled if 12 to 24 inches tall.
		Lambsquarters and Chinese thornapple were too large for effective control at the time of the layby Roundup applications with a hooded sprayer.

	Late Season Weed Escapes in Indiana Soybean Fields
		Weed diversity was highest in southeastern and northwestern Indiana with 57% and 54%, respectively, followed by northeastern Indiana with 42% of the fields containing at least 3 weed species.
		In southeastern Indiana, the predominant weeds were horseweed (47%), giant ragweed (17%), giant foxtail (7%), and common lambsquarter and fall panicum (5% each).
		Visual estimates of weed density suggest horseweed infestations were high enough (10% or more of field infested) to cause economic losses in 0, 0, and 28%, respectively, of fields in northeastern, northwestern, and southeastern Indiana.

	Weed Management in Soybeans
		If the predominant weed problem is annual grasses plus pigweed, lambsquarter, or both, one of these preplant-incorporated herbicides plus cultivation may be adequate.
		This preemergence herbicide controls common ragweed, pigweed, and lambsquarter but is inadequate for control of most other broadleaf weeds (Table 2).
		Major exceptions are lambsquarter, sicklepod, smartweed, and spurred anoda.

	Pre-Emergent Herbicides Effective for Weed Control (Site not responding. Last check: 2007-10-20)
		Jeff Stachler, an Ohio State University Extension weed specialist, said that pre-emergence herbicide applications can drastically improve the control of lambsquarter, giant ragweed and marestail (horseweed) in corn and soybean fields, but their effectiveness is contingent upon how they are incorporated into management practices.
		However, for the last two to three years more conventional tillage soybean growers are having difficulty controlling some key weed species, especially lambsquarter and giant ragweed.
		The best method for controlling marestail, giant ragweed and lambsquarter is to incorporate pre-emergence herbicides into other herbicide programs, ones that make use of several herbicide application timings and a diversity of herbicides to compensate for existing or developing resistance issues.

	Ag Answers: Pre-emergence herbicides hard to resist for weeds
		Jeff Stachler, an Ohio State University Extension weed specialist, said that pre-emergence herbicide applications can drastically improve the control of lambsquarter, giant ragweed and marestail in corn and soybean fields, but their effectiveness is contingent upon how they are incorporated into management practices.
		Glyphosate-resistance marestail is already abundant in Ohio, and we believe that some populations of giant ragweed and lambsquarter are evolving to have a low level of resistance to glyphosate, all of which is being attributed to the intensive usage of this particular herbicide."
		However, for the past two to three years more conventional tillage soybean growers are finding it difficult controlling some key weed species, especially lambsquarter and giant ragweed.
