SOIL ATTRIBUTES AND THE EFFICIENCY OF SULFENTRAZONE ON CONTROL OF PURPLE NUTSEDGE (Cyperus rotundus L.)
In the soil, herbicides are submitted to absorption, leaching and degradation by physical, chemical and biological processes or absorbed by plants. All these processes are dependent on soil class and weather conditions and affect the product efficiency on weed control. The objective of this work was to investigate the influence of soil attributes on sulfentrazone efficiency for controlling purp...
متن کاملEvaluation 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 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...
متن کاملMorphological and physiological responses of lowland purple nutsedge (Cyperus rotundus L.) to flooding
BACKGROUND AND AIMS Purple nutsedge (Cyperus rotundus L.) is a major weed of upland crops and vegetables. Recently, a flood-tolerant ecotype evolved as a serious weed in lowland rice. This study attempted to establish the putative growth and physiological features that led to this shift in adaptation. METHODOLOGY Tubers of upland C. rotundus (ULCR) and lowland C. rotundus (LLCR) ecotypes were...
متن کاملeffect of soil solarization on the control of different purple nutsedge (cyperus rotundus l.) ecotypes
employment of solarization using the polyethylene mulch can be effective as a non-chemical approach for some control noxious weed management such as purple nutsedge (cyperus rotundus). in order to determine the effect of different levels of polyethylene mulches including one- layer clear polyethylene film, two- layer clear polyethylene film, one- layer black polyethylene film and two- layer bla...
