chenopodium polyspermum/necrosis

Chenopodium album L. ssp. album is a common plant species worldwide, especially in humid areas. Sun exposure after oral intake of the plant can lead to sunburn-like rashes owing to its furocoumarin content. In this article, we reported nine patients who developed dermatitis with edema, erythema and

The focus of this double-blind randomized study was on evaluating the effect of an aqueous extract of Mastruz (Chenopodium ambrosioides L.) on the bone repair process in vivo. In total, 36 male Wistar rats were randomly selected for this study, and divided into 3 groups (n = 12): Group HS

Amaranthus retroflexus (redroot pigweed)-induced nephrotoxicity was diagnosed in 6 herds of cattle from 3 counties in southwest Missouri. Forty-eight cows and calves died and another 35 were clinically affected. Serum urea nitrogen concentration, determined in 4 affected calves, was between 55 and

Two outbreaks of Amaranthus retroflexus (redroot pigweed) poisoning occurring in cattle in southern Brazil in late summer and early autumn are described. In both instances too many cattle were held in small paddocks heavily invaded by A retroflexus in its seeding stage. In 1 herd 8/28 heifers and in

Temperature, humidity, weed species and age, and inducible responses in the host are factors that could limit the efficacy of fungal bioherbicides. The influences of these factors on the efficacy of the fungal bioherbicides Phomopsis amaranthicola and Microsphaeropsis amaranthi against Palmer

Forty seven of 150, 15-month-old long weaners died of an acute renal disease syndrome following introduction into an old maize field with a heavy stand of Amaranthus spp. The clinical syndrome was characterised by sudden onset neurological disease with ataxia and recumbency. Subcutaneous oedema,

A study was undertaken to assess the phytotoxicity of citronellal, an oxygenated monoterpenoid with an aldehyde group, towards some weedy species [Ageratum conyzoides L., Chenopodium album L., Parthenium hysterophorus L., Malvastrum coromandelianum (L.), Garcke, Cassia occidentalis L. and Phalaris

The effect of applied nitrogen (N) on the growth, leaf expansion rate, biomass partitioning and leaf N levels of Chenopodium album (C(3)) and Amaranthus retroflexus (C(4)) were investigated. At a given applied N level, C. album had 50% greater leaf N per unit area (N(a)) than A. retroflexus. Nitrate

Herbicides are the most commonly used means of controlling weeds. Recently, there has been growing concern over the potential impacts of global climate change, specifically, increasing temperatures and elevated carbon dioxide (CO₂) concentrations, on the sensitivity of weeds to

Amaranthus hybridus has been identified as an important alternative vegetable crop with potential for increased commercial production in South Africa (1). In summer 1999, severe losses occurred in a large plot of 2-month-old A. hybridus plants on an experimental farm near Bloemfontein, South Africa.

Papaya ringspot virus (PRSV, genus Potyvirus, family Potyviridae) is economically important due to its worldwide distribution and because it can cause serious losses in both cucurbit crops and papaya (3). PRSV has been previously reported from cucurbit crops in Iran (2). In Khuzestan Province,

The effect of leaf necrosis caused by Ascochyta caulina (P. Karst.) v.d. Aa & v Kest. on photosynthesis of leaves of Chenopodium album L. was studied in growth chambers. Fully expanded leaves of young plants were sprayed with a suspension of pycnidiospores, or with a spore-free control solution.

Sudden death syndrome, caused by Fusarium virguliforme, is an important disease of soybean in the United States. Fifteen species of crops, weeds, or prairie plants were evaluated for their potential as hosts of F. virguliforme. Root and foliar symptoms and plant biomass were assessed following

Cucumber mosaic virus (CMV) expressing the green fluorescent protein (GFP), and lacking either the 3a movement protein or the coat protein (CP), failed to induce a hypersensitive response producing local lesions in inoculated leaves of Chenopodium amaranticolor. Cytological analysis showed that both

The current study has been conducted to evaluate the effect of different processing techniques on the 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity and the gastroprotective potential of Chenopodium quinoa red seeds in acute gastric injury induced by absolute ethanol in rats. Seven
