Última Identifying Optimum Herbicide Mixtures to Manage and Avoid Fenoxaprop-p-Ethyl Resistant Phalaris minor in Wheat Planta Daninha ABBAS,T.; NADEEM,M.A.; TANVEER,A.; AHMAD,R.. ABSTRACT Use of herbicide mixtures has been advocated as most effective strategy for avoidance and management of herbicide resistant weeds. Effect of twelve selected treatments of four herbicides (clodinafop-propargil, metribuzin, pinoxaden and sulfosulfuron) two-way mixtures at different doses was investigated against fenoxaprop-p-ethyl resistant and susceptible populations of P. minor grown along the wheat plants. In repeated experiment, herbicides mixtures were applied at 3 to 4 leaf stage of P. minor under greenhouse conditions. All the herbicide mixtures were effective to control resistant as well as susceptible P. minor. Mixtures having 75% lethal dose of each mixture component provided best control against P. minor. Mixtures with 50% lethal dose of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Herbicide mixtures; Resistance management; Resistance avoidance; Triticum aestivum; Erva-cabecinha.

ABSTRACT: Recent increases in the development of herbicide resistance in Phalaris minor worldwide demand alternative non-chemical strategies to control this weed. A series of experiments were conducted under laboratory and greenhouse conditions to explore the herbicidal potential of four allelopathic crops, including maize, rice, sorghum and sunflower, at different concentrations of aqueous extracts (2.5% and 5%), residues (1%, 2% and 4%) and mulches (4, 8, and 12 ton ha-1) against fenoxaprop-resistant P. minor. Aqueous extracts, residues and mulches provided 86-100%, 73-100% and 16-40% control of this resistant weed biotype, respectively. The dry biomass reduction due to aqueous extracts, residues and mulches was 48-100%, 48-100% and 20-54%, respectively....

ABSTRACT Aquatic weeds are higher plants found in the aquatic ecosystem and in anaerobic rice fields, where they have no economic benefits. The continuance of aquatic weeds is more widespread than terrestrial weeds because in aquatic ecosystems there is very little fluctuation in the environmental conditions compared with terrestrial ecosystems. Scientists have been working to address the harmful allelopathic effects of aquatic weeds on the aquatic ecosystem, but limited information is available on the allelopathic influence of aquatic weeds on agro-ecosystems through the release of phytotoxic compounds. Phytotoxic chemicals released by different aquatic weeds into irrigation water and/or directly into rice ecosystems might have a significant inhibitory...

ABSTRACT Hormetic effects of herbicides at ultra-low doses have been proved against range of crop species, although available data of herbicides hormesis about the weeds growth is very limited. This study investigates the promotive effect of low doses of fenoxaprop-Pethyl on growth and seed production of littleseed canarygrass and wild oat. Pot experiments were conducted twice in Wire House at Agronomic Research Area, University of Agriculture, Faisalabad, during 2014-15. Seven different concentrations of fenoxaprop-P-ethyl [0, 1, 3, 6, 9, 12 and 15 g a.i. ha-1] were applied as post emergence herbicide at 3-4 leaves stage of the weeds. Results revealed that increase in growth occurred within first two weeks after spraying at fenoxaprop-P-ethyl doses 1, 3...

Avulsos de Zool. (São Paulo) Abbate,Daniel; Cavallari,Daniel Caracanhas. Nassarius levis sp. nov. is described from Canopus Bank, off Ceará, Northeast Brazil, based on shell morphology. It differs from other Brazilian species of the genus in having a more elongate shell, with a weakly developed parietal shield and a notably smooth surface. This last trait has not yet been described among the Western Atlantic Nassarius, but it is common to other congeners from the Eastern Atlantic, such as Nassarius elatus (Gould, 1845) and the Indo-Pacific, such as Nassarius excellens (Kuroda & Habe, 1961).

At our institution, we observed an increase in the incidence of healthcare-associated infections (HAI) due to Gram-negative bacilli, including three cases of carbapenem-resistant Klebsiella pneumoniae, among patients who underwent renal transplantation. In addition to strengthening infection control measures, we chose to add gentamycin to the antibiotic prophylaxis regimen of patients undergoing renal transplantation. We assessed the number of HAI occurring within 30 days of renal transplantation during two time periods: (1) the preintervention period, between September 2009 and June 2010, and (2) the post-intervention period, between July 2010 and April 2011. The intervention consisted of the addition of gentamycin to the surgical antibiotic prophylaxis...

Bras. Ciênc. Solo Abbruzzini,Thalita Fernanda; Silva,Carlos Alberto; Andrade,Daniela Aparecida de; Carneiro,Waldete Japiassú de Oliveira. There are currently many devices and techniques to quantify trace elements (TEs) in various matrices, but their efficacy is dependent on the digestion methods (DMs) employed in the opening of such matrices which, although "organic", present inorganic components which are difficult to solubilize. This study was carried out to evaluate the recovery of Fe, Zn, Cr, Ni, Cd and Pb contents in samples of composts and cattle, horse, chicken, quail, and swine manures, as well as in sewage sludges and peat. The DMs employed were acid digestion in microwaves with HNO3 (EPA 3051A); nitric-perchloric digestion with HNO3 + HClO4 in a digestion block (NP); dry ashing in a muffle furnace and solubilization of residual ash in nitric acid (MDA); digestion by using aqua...

The Vernier acuity of 50 normal untrained subjects (20 males and 30 females) was measured by the method of adjustment. Subjects were divided into five age ranges with 10 subjects in each age group: 5-10, 11-20, 21-30, 31-40, and 41-50 years. All subjects had normal visual acuity (20/20) and volunteered to participate in the experiment. Children were selected from a local school and adults recruited from the technical staff of the Department of Ophthalmology of the School of Medicine. Vernier acuity was higher in adults compared to children. Intraindividual variability was high and it was estimated that for most individuals of all age groups a range of 100 to 700 trials was necessary to obtain a mean with a precision of 10%.
