Abstract:

A biotype of the annual grass weed hare barley infesting an alfalfa field with a 24-yr history of the use of the bipyridylium herbicides paraquat and diquat, was investigated for resistance to these herbicides. Rates of up to 800 g ai ha–1of each herbicide caused no mortality in the hare barley plants from this field. The same species, collected from an adjacent pasture field with no history of bipyridylium herbicide application, exhibited LD50'sof 57 and 160 g ai ha–1for paraquat and diquat, respectively. Tiller numbers and dry matter production in the biotype from the alfalfa field were not

Abstract:

Landoltia was collected and cultured from a canal in Lake County, Florida, where diquat was used repeatedly during the past 20–30 yr for duckweed control. Recent applications of diquat failed to provide adequate control of duckweed, and a new commercial formulation of diquat was suspected. The new formulation was not the cause of reduced efficacy. Static exposures (48 h) to various concentrations of diquat were used to compare the susceptibility of the Lake County landoltia accession to one never exposed to diquat. These static tests indicated that landoltia, from a population with no prior hi

Abstract:

This review considers the development of herbicide-resistant weed biotypes in Australia. Biotypes of the important annual weed species, capeweed, wall barley, and hare barley are resistant to the bipyridylium herbicides paraquat and diquat. These resistant biotypes developed on a small number of alfalfa fields that have a long history of paraquat and diquat use within a distinct geographical area in central western Victoria. The resistant biotypes are controlled by alternative herbicides and pose little practical concern. Some populations of wild oat are resistant to the methyl ester of diclof

Abstract:

The kinetics of [14C]paraquat (N,N-di[14C]methyl-4,4'-bipyridylium) uptake from the pulmonary circulation were investigated in rat lungs perfused in situ. During the 1st h of exposure to the herbicide paraquat entered the lungs primarily by diffusion; no evidence was obtained from concentrative uptake, saturation kinetics (1-3,500 microM paraquat), or inhibition by the amines methyl-glyoxal bis(guanylhydrazone) or spermidine, both of which were expected to compete for paraquat transport sites. In contrast, after 60 min of exposure, uptake rates increased two- to three-fold, and paraquat was ac

Abstract:

The soybean cultivars “ Kwangkyo” and “ Hood ” are differentially sensitive to the bipyridylium herbicide paraquat (1,1′-dimethyl-4 ,4′-bipyridiniumion). This was confirmed by visible injury observations, measurements of desiccation levels and chlorophyll content, and tracings of chlorophyll fluorescence induction of fully expanded first trifoliate leaves of these two cultivars after exposure to a wide range of paraquat concentrations. The margin of this intraspecific differential tolerance to paraquat was narrow an d the ratio of the paraquat concentrations causing 50% injury to the tolerant

Abstract:

Abstract The herbicide paraquat (1,1′-dimethyl-4,4′-bipyridylium dichloride; PQ), is a poison known to cause delayed mortality due to lung and kidney injuries. High-resolution proton nuclear magnetic resonance (1H NMR) spectroscopy has been extensively applied in evaluating nephrotoxicity by the characteristic perturbations in the excretion pattern of low molecular weight endogenous metabolites. The application of the method allows the rapid localization of the renal injury noninvasively. In this study, we report 1H NMR and conventional clinical chemistry urinalysis in two patients suffering f

Abstract:

The heterogeneous photocatalyst based on titanium dioxide has been widely investigated as an attractive treatment method for water pollution. Herbicide like paraquat dichloride is one of the toxic organic pollutants which is harmful to human and animal and is still being used in agricultural sectors. TiO2doped with zirconium element has been proven to enhance the photocatalytic activity of TiO2from the previous study. Therefore in this study, photodegradation of paraquat dichloride (1,1-dimethyl-4,4’-bipyridylium dichloride) under UV irradiation was studied using TiO2and Zr doped TiO2prepared
