Growth and nutrient uptake of seven tree species were evaluated with the goal of selecting the species that can be used for wastewater enhancement by dendro-purification, or green tree filtering, and for restoration of riparian woodlands. Trees were grown in pots with an inert mixture of perlite and vermiculite and irrigated with either nutrient solution or treated wastewater We measured the ef...

OBJECTIVE To describe the cardiac arrhythmias, electrolyte disturbances, and serum cardiac glycoside levels seen in patients presenting to hospital with acute yellow oleander (Thevetia peruviana) poisoning and to compare these with published reports of digitalis poisoning. DESIGN Case series. SETTING Medical wards of Anuradhapura District General Hospital, Sri Lanka, and coronary care unit ...

Ingestion of oleander plant, containing the cardiac glycoside oleandrin, has been reported to induce fatal poisonings. Derivatives of oleandrin are structurally similar to digoxin. We investigated the cross-reactivities of oleandrin and its aglycone metabolite, oleandrigenin, in several commercially available digoxin immunoassays; assessed their ability to inhibit Na,K-ATPase catalytic activity...

This research aimed at exploring eco-friendly green synthesis of CuNPs using different plant species used for purpose were Nyctanthes arbor-tristris (Night jasmine), Gardenia jasminoides (Cape Tabernaemontana divartica (Crape Cascabela thevetia (Yellow oleander), Clerodendrum inerme (Glory bower), Hibiscus rosa-sinensis (China rose) and Allamanda cathartica (Allamanda) synthesizing CuNPs. Out s...

The regulation of an asexual population of the oleander scale [Aspidiotus nerii Bouchè (Hemiptera: Diaspididae)] on California bay tree [Umbellularia californica (Hopk. & Arn.) Nut.] by two natural enemies; an idiobiont, ectoparasitoid Aphytis chilensis Howard (Hymenoptera: Aphelinidae) and a coccinellid predator (Rhysobius lophanthae (Blaisd.) (Coleoptera: Coccinellidae), was examined using a ...

Paclobutrazol (PBZ) is a retardant often used in potted ornamental plants to control their growth and compactness. The distribution in plant, substrate and leachate of PBZ applied to containerized oleander seedlings were studied after a single liquid drench application to the substrate surface (20 mg a.i. per plant) in a nursery dedicated to pot production in SE Spain. PBZ significantly reduced...

Background. Outbreaks of the West Nile virus infection were reported in Morocco in 1996, 2003, and 2010. Culex pipiens was strongly suspected as the vector responsible for transmission. In the North center of Morocco, this species has developed resistance to synthetic insecticides. There is an urgent need to find alternatives to the insecticides as natural biocides. Objective. In this work, the...

Two instrumented test sections were constructed in summer 1999 at the Kiefer Landfill near Sacramento, California to test the hydraulic performance of two proposed alternative final covers. Both test sections simulated monolithic evapotranspiration (ET) designs that differed primarily in thickness. Both were seeded with a mix of two perennial and one annual grass species. Oleander seedlings wer...
