Evaluation of Imazosulfuron for Yellow Nutsedge (Cyperus esculentus) and Broadleaf Weed Control in Potato
Field studies were conducted in 2007 and 2008 near Nyssa, OR, and Pasco and Paterson, WA to evaluate yellow nutsedge and broadleaf weed control and potato tolerance to imazosulfuron. No injury symptoms from imazosulfuron were evident on potato at Nyssa, whereas in Washington, imazosulfuron caused some chlorosis of potato foliage ranging from 6 to 15% and , 4% at 6 and 15 d after POST applicatio...
متن کاملCloning and characterization of ADP-glucose pyrophosphorylase small subunit gene in Cyperus esculentus (yellow nutsedge).
ADP-glucose pyrophosphorylase (ADPGlcPPase) controls the first committed step of starch synthesis by catalyzing the biosynthesis of ADP-glucose from glucose-phosphate and ATP. It is a tetrameric protein consisting of two small and two large subunits. The small subunits have a catalytic function, while the large subunits regulate the enzyme activity. Cyperus esculentus (yellow nutsedge) is a per...
متن کاملEffects of elevated atmospheric CO2 on invasive plants: comparison of purple and yellow nutsedge (Cyperus rotundus L. and C. esculentus L.).
The rise in atmospheric CO(2) concentration coupled with its direct, often positive, effect on the growth of plants raises the question of the response of invasive plants to elevated atmospheric CO(2) levels. Response of two invasive weeds [purple nutsedge (Cyperus rotundus L.) and yellow nutsedge (Cyperus esculentus L.)] to CO(2) enrichment was tested. Plants were exposed to ambient (375 micro...
متن کاملPhytochemical observation and antibacterial activity of Cyperus esculentus L.
In the present study various extracts of Cyperus esculentus L. such as acetone, 50% ethanol, chloroform and petroleum ether were evaluated for their antibacterial activity against several human pathogens such as Escherichia coli, Staphylococcus aureus, Salmonella sp, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa and Citrobacter freundii, by using disc diffusion method. The act...
متن کاملNutsedge (cyperus Spp) Control in Alfalfa
The competitive advantage of purple and yellow nutsedge in low desert alfalfa production areas of Southern California and Arizona is due to a combination of factors. These include frequent harvest and irrigation, high incident solar radiation, high summer temperatures that are supraoptimal for alfalfa growth, and the presence of C4 photosynthesis and vegetative reproduction (e.g., tubers) in nu...
