Weeds compete with crops and are hard to differentiate identify due their similarities in color, shape, size. In this study, the weed species present sorghum (sorghum bicolor (L.) Moench) fields, such as amaranth (Amaranthus macrocarpus), pigweed (Portulaca oleracea), mallow (Malva sp.), nutgrass (Cyperus rotundus), liver seed grass (Urochoa panicoides), Bellive (Ipomea plebeian), were discrimi...

The results of seven pre-emergence herbicide screening trials involving 27 chemicals are presented. The experiments, which were conducted over a fouryear period, differed with respect to soil moisture conditions, soil type and prevailing weed flora. Special attention was directed to the control of Cyperus esculentus, C. rotundus and grasses. Mean visual assessmenlts of control of species or spe...

OBJECTIVES Global cerebral ischemia-reperfusion injury causes loss of pyramidal cells in CA1 region of hippocampus. In this study, we investigated the possible neuroprotective effects of the ethanol extract of Cyperus rotundus (EECR) on a model of global transient ischemia in rat, by evaluating the pathophysiology of the hippocampal tissue and spatial memory. MATERIALS AND METHODS Treatment g...

ischemia-reperfusion injury is the tissue damage happened when blood supply returns to the tissue after a period of ischemia or shortage of oxygen. this brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. the aim of this study is investigating the effect of hydroalcoholic extract of  cyperus rotundus l. on the expression of the bcl-x1 an...

The study was conducted to understand the influence of herbicide on changes in physiology and biochemical properties purple nutsedge weed (Cyperus rotundus L.). Laboratory pot culture were at Department Agronomy, Tamil Nadu Agricultural University, Coimbatore during 2020-21. Glyphosate tested with different concentrations (500, 600, 700, 800, 900 1000 ppm) various soaking duration (6, 12, 24 48...

BACKGROUND AND AIMS In recent years, Cyperus rotundus has become a problem weed in lowland rice (Oryza sativa) grown in rotation with vegetables in the Philippines. As the growth of C. rotundus is commonly suppressed by prolonged flooding, the ability of the weed to grow vigorously in flooded as well as upland conditions suggests that adapted ecotypes occur in these rotations. Studies were cond...

Cyperus rotundus Linn. rhizomes extracts were evaluated against six important pathogenic microbes viz. Staphylococcus epidermidis, Bacillus cereus, Pseudomonas aeruginosa, Escherichia coli, Aspergillus niger and Candida albicans . The powdered rhizome extracts were successively extracted with petroleum ether, chloroform, ethanol and water using Soxhlet apparatus. The antibacterial and antifunga...

The essential oils from the rhizomes of Cyperus rotundus L. collected from two different locations (Empangeni-A and KwaDlangezwa-B; both in the Kwa-Zulu Natal Province of South Africa) were obtained by hydrodistillation and analyzed by capillary GC and GC/MS. Forty-one and 43 components were identified, representing 89.9% and 92.0% of sample A and sample B, respectively. Alpha-cyperone (11.0%),...

BACKGROUND The protective effect of the chloroform extract of Cyperus rotundus (CHCR) is attributed to its anti-inflammatory and antioxidant activities. Cytokines, important regulators of inflammation and repair, play a key role in the pathogenesis of inflammatory bowel disease (IBD). Targeting these cytokines can effectively ameliorate the symptoms of IBD. The aim of the present study was to u...
