Many large-scale management programs directed toward the control of waterhyacinth rely on maintenance management with herbicides. Improving the implementation of these programs could be achieved through accurately detecting herbicide injury in order to evaluate efficacy. Mesocosm studies were conducted in the fall and summer of 2006 and 2007 at the R. R. Foil Plant Science Research Center, Miss...

Mycotoxins are secondary fungal metabolites, toxic to humans, animals and plants. Among the hundreds of known mycotoxins, aflatoxins, citrinin, patulin, penicillic acid, tenuazonic acid, ochratoxin A, cytochalasins, deoxynivalenol, fumonisins, fusarin C, fusaric acid, and zearalenone are considered the types that most contaminate cereal grain. The majority of the mycotoxins in these groups are ...

Brassica oleracea L. var. capitata L.) and beetroot (Beta vulgaris L.) was obtained at 2075 and 4505 mg kg 1 Ni In situ remediation (phytostabilization) is a cost-effective solution in soil, respectively. On the muck soil containing 1200 for restoring the productivity of metal-contaminated soils and protection of food chains. A pot experiment with wheat (Triticum aestivum mg kg 1 Ni, the predic...

Dry olive mill residue (DOR) from the olive oil production by two phase centrifugation system was fractionated by a consecutive continuous solid-liquid extraction obtaining the EAF, PF, MF and WF fractions with ethyl acetate, n-propanol, methanol and water, respectively. The chemical, chromatographic and mass spectrometric analyses showed EAF, PF and MF to be mainly composed of simple phenols, ...

Abstract Powdery mildew, caused by Podosphaera xanthii , is a devastating disease that can wipe out cucumber crop in optimal weather conditions. Disease control management depends mainly on fungicides to inhibit the pathogen. However, they have fatal side effects most organisms. This study evaluated use of natural products as safe alternatives for controlling powdery mildew. The effectiveness a...

The main objective of this study was to determine the allelopathic impact of dominant species (Calamagrostis epigeios, Rubus idaeus and Chamaenerion angustifolium) of clear-cuttings of Scots pine (Pinus sylvestris L.) forests (Vaccinio-myrtillo Pinetum) on test species germination emphasizing the forest ecosystem establishment. Aqueous extracts of roots and shoots were produced at different gro...

The effect of molasses alone or combined with Trichoderma asperellum T34 Biocontrol® was assessed on Meloidogyne reproduction, disease severity, and density activity soil microorganisms in pot field experiments. Firstly, application at 1 mL m−2 four different textured soils. Secondly, 5, 10, 20, 40 m−2, T34, experiments 10 two effective reducing nematode reproduction the loam but not sandy clay...
