Non-target-site resistance to ALS inhibitors in waterhemp
The acetolactate synthase (ALS) enzyme, or acetohydroxyacid synthase (AHAS) enzyme, is an essential enzyme in branched-chain amino acid biosynthesis, and is the target site of five families of herbicides referred to as ALS inhibitors. Waterhemp (Amaranthus tuberculatus) is considered one of the …

Multiple Herbicide Resistance in Waterhemp
… treatment of several acetolactate synthase (ALS) inhibitors, and a POST application of lactofen, a protoporphyrinogen oxidase (PPO)-inhibiting herbicide. Greenhouse studies were conducted with this waterhemp biotype, and revealed that plants were also resistant to atrazine, a photosystem II …

Resistance to Als-Inhibiting Herbicides in Common Ragweed, Foxtail and Horseweed
… ragweed evolved in response to selection by ALS inhibitors other than cloransulam. Also, resistance-conferring ALS alleles were used to develop a marker to assess the genotype of horseweed at codons encoding amino acid position 197. In this way we have found an effective approach to confirm …

A waterhemp saga: Seed production, genetics, hybridization, and the creation and discovery of quad-stack individuals
… the crossing of a population resistant to ALS inhibitors, PPO inhibitors and PS II inhibitors with the glyphosate-resistant Missouri population) were investigated in Chapter 4 for the presence of four types of resistance, and individual plants were identified containing all four resistance …

Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
… in the spring using amino acid biosynthesis inhibitors, acetolactate synthase (ALS) inhibitors and growth regulator herbicides. Results indicate poison hemlock is a prolific and viable seed producer (between 1,700 to 39,000 seed per plant), and portions of seed were capable of germination …

Characterization of HPPD-inhibitor resistance in waterhemp (Amaranthus tuberculatus)
… a review of the literature pertaining to HPPD inhibitors, namely their discovery and uses as herbicides, as well as a section on waterhemp biology. Chapter 2 discusses the initial greenhouse research used to determine if the waterhemp population from McLean Co. (designated MCR) had indeed …

Preemergence activity of chloroacetamide herbicides on a multiple herbicide-resistant population of waterhemp (amaranthus tuberculatus)
… groups including: acetolactate synthase (ALS) inhibitors, 5-enolpyruvyl-shikimate-3-phosphate (EPSPS) inhibitors, protoporphyrinogen oxidase (PPO) inhibitors, synthetic auxins, Photosystem II inhibitors (PSII), and 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors. Chloroacetamide …

Characterization and Management of Acetolactate Synthase Inhibiting Herbicide Resistant Mouse-Ear Cress (Arabidopsis thaliana) in Winter Wheat
… case of field evolved acetolactate synthase (ALS) inhibiting herbicide resistance in the model plant, mouse-ear cress, was reported in winter wheat fields in Westmoreland County, Virginia. A putative resistant (R) mouse-ear population was assessed for ALS resistance relative to a putative …

Investigations on the Interations of Acetolactate Synthase (ALS)-Inhibiting Herbicides with Growth Regulator and non ALS-Inhibiting Herbicides in Corn (Zea mays) and Selected Weeds
… examine the interactions of 2,4-D, dicamba, and ALS-inhibitor herbicides with rimsulfuron plus thifensulfuron-methyl (RT) and with sethoxydim on giant foxtail, common ragweed, and common lambsquarters control in corn. Combinations of halosulfuron-methyl with 2,4-D or dicamba were generally …
