Photodynamic Herbicide Modulators
… species, was highly susceptible to photodynamic herbicides. Protochlorophyllide was the most ubiquitous of the damage-causing anabolic photodynamic tetrapyrroles that accumulated as a result of treatments that consisted of ALA and one chlorophyll biosynthesis modulator. Furthermore, DDV/LDV plant …

Multiple Herbicide Resistance in Waterhemp
… 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 (PSII)-inhibiting herbicide. A waterhemp line selected for multiple herbicide resistance, designated …

Disposal Methods for Diluted Herbicide Rinsates
… was to develop a new disposal method for diluted herbicide rinsates. The thirteen herbicides used in this experiment were: atrazine cyanazine, simazine, metribuzin, linuron, oryzalin, trifluralin, fluchloralin, butylate, alachlor, metolachlor, 2,4-D DMA {dimethyl amine salt}, chloramben (ammonium …

Enzyme-linked immunosorbent assay for herbicide detection
… to develop polyclonal antibodies to the soybean herbicides clomazone (2- ((2 chlorophenyl)methyl) -4,4-dimethyl-3-isoxazolidinone), imazaquin (2- (4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl) -3-quinolinecarboxylic acid), and metribuzin …

Fate of the herbicide clomazone in soil
… the environmental properties of the soil-applied herbicide clomazone. The effects of soil microbial activity, temperature, and moisture on clomazone fate were determined following ($\sp{14}$C) clomazone application to the surface of a Flanagan silty clay loam. Degradation of clomazone was a …

Population genetics of herbicide resistance in waterhemp
Waterhemp populations resistant to herbicides that inhibit protoporphyrinogen oxidase (PPO) have been identified throughout the Midwest and the mechanism of resistance in populations from Illinois was previously determined to result from a 3 base pair deletion in the protoporphyrinogen oxidase …

Physiological studies with the experimental herbicide isouron
… to investigate the mode of action of a new herbicide, isouron (N-(5-(1,1-dimethylethyl)-3-isoxazolyl)-N,N-dimethylurea). These studies included two plant metabolites of isouron, a monomethylurea (N-(5-(1,1-dimethylethyl)-3-isoxazolyl)-N-methylurea) and a urea derivative …

Herbicide Mediated Selection of Sulfonamide Resistant E. coli
Asulam is an herbicide that is structurally analogous to sulfonamide antibiotics (sulfas), with the potential to contribute to the global antibiotic resistance crisis by cross-selecting for sulfa-resistant bacteria. To determine if asulam can select for antibiotic resistant bacteria, isothermal …

Responses of selected chickpea cultivars to imidazolinone herbicide
… in Saskatchewan, there is heavy reliance on herbicides. The chickpea breeding program at the Crop Development Centre, University of Saskatchewan, has developed chickpea cultivars with resistance to imidazolinone (IMI) class of herbicides. The objectives of this study were: (i) to examine the …

GENETICS OF GROUP 14 HERBICIDE TOLERANCE IN LENTIL
Extremely weak competition with weeds and limited herbicide options dictate the need to explore new avenues in weed control for lentil. Sulfentrazone and fluthiacet methyl are two herbicides of group 14 which have not previously been used in lentil production. Tolerance to these two products was …

Herbicide resistant weeds in Missouri : sources and solutions
Herbicide resistant weeds continue to invade new territories each year. Two studies were designed to identify both the spread and the current status of herbicide resistant weeds in Missouri. In 2016 and 2017, 98 separate commercially available bird feed mixes were examined for the presence of weed …

Visualizing and Characterizing Herbicide Activity in Plant Leaves
However, a greater diversity of herbicide physicochemical properties and in vitro potencies would expand the usefulness of this model.

Genetically Engineered Herbicide Tolerant Canola: A Multiple Account Evaluation
… assesses the affect of genetically engineered herbicide tolerant rapeseed through the use of a multiple account evaluation. In 1995, rapeseed tolerant to the non-selective weed control product Roundup was licensed for use in Canada. Applying Roundup in crop as a weed control method is expected …

Discovery, surveillance, and management of herbicide-resistant amaranthus spp
… Midwestern agricultural production systems. Herbicides are often relied upon for the control of Amaranthus spp. In recent years, herbicide resistance at multiple sites of action, such as 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) and protoporphyrinogen oxidase (PPO), have become …
