Weed Technology, 2008
Field studies were conducted in 2006 and 2007 to evaluate strategies for management of four glyphosate-tolerant common lambsquarters populations in glyphosate-resistant soybeans. Treatments consisted of several different preplant herbicide combinations followed by one or two postemergence applications of 0.84 to 3.36 kg ae/ha of glyphosate.

Field studies were carried out at two sites in 2005 using common lambsquarters seed collected from long-term research plots near Scottsbluff, NE; Fort Collins, CO; and Torrington, WY, to determine the effect of herbicide selection pressure on glyphosate susceptibility.

Triazine-resistant common lambsquarters (TR-CHEAL) is a widespread weed problem in the northcentral United States. Field studies were conducted from 1995 to 1997 to determine the efficacy and consistency of metolachlor, pendimethalin, and acetochlor applied preemergence (PRE) for control of TR-CHEAL in corn.

Biotypes of common lambsquarters with tolerance to glyphosate have been identified in a number of states, but little is known about their fitness characteristics. Field and greenhouse studies were conducted to characterize the response of selected glyphosate-tolerant common lambsquarters biotypes to glyphosate, and also their biological and ...

Calibration and validation of a common lambsquarters (Chenopodium album) seedling emergence model
Weed Science, 2004Studies were conducted to calibrate and validate a mathematical model previously developed to predict common lambsquarters seedling emergence at different corn seedbed preparation times. The model was calibrated for different types of soil by adjusting the base temperature of common lambsquarters seedling emergence to the soil texture.

Common Lambsquarters (Chenopodium album) Interference in Sugarbeets (Beta vulgaris)
Weed Science, 1983Interference of common lambsquarters (Chenopodium albumL.) in sugarbeets (Beta vulgarisL. ‘Mono Hy D2′) was determined in a 2-yr field experiment. Yield of sugarbeet roots and recoverable sucrose/ha decreased as the density of common lambsquarters increased.

Abstract Widespread use of crop yield loss models based on weed density has been limited on account of spatial and temporal variability. Furthermore, research characterizing crop yield loss associated with two or more weed species is lacking for many cropping systems.

Summary Pyridate resistance was not a problem in maize fields (in area of Ipolytarnooc) in Hungary until we found a triple (atrazine, pyrazon and pyridate)-resistant common lambsquarters ( Chenopodium album L.) population (it is to be remarked that we do not find single pyridate-resistant populations of Chenopodium album L.).

Response of Common Lambsquarters (Chenopodium album) to Glyphosate as Affected by Growth Stage
Weed Science, 2007Experiments were conducted to determine the efficacy of glyphosate on four common lambsquarters populations collected from Kansas, Nebraska, North Dakota, and Ohio. Glyphosate dose-response studies for common lambsquarters treated at 2.5-, 7.5-, and 15-cm heights showed that glyphosate at 1.1 kg ae ha−1caused more than 80% injury to 2.5-cm plants but ...

Use of Ethylene and Nitrate to Break Seed Dormancy of Common Lambsquarters (Chenopodium album)
Weed Science, 1986Effects of ethylene and KNO3on the germination of dormant common lambsquarters (Chenopodium albumL. # CHEAL) seed were studied under controlled environmental conditions. Ethylene, applied in the gaseous form or as an aqueous solution of ethephon (2-chloroethylphosphonic acid), was able to overcome the dormancy of over 70% of the seed.
