Influence of grain type on the efficacy of spinetoram for the control of Rhyzopertha dominica, Sitophilus granarius and Sitophilus oryzae
Vassilakos, T. N.; Athanassiou, C. G.; Tsiropoulos, N. G. (2015)The efficacy of spinetoram against adults of three major stored grain beetle species, the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), the granary weevil, Sitophilus granarius (L.) (Coleoptera: ... -
Isolation of soil bacteria able to hydrolyze both organophosphate and carbamate pesticides
Chanika, E.; Georgiadou, D.; Soueref, E.; Karas, P.; Karanasios, E.; Tsiropoulos, N. G.; Tzortzakakis, E. A.; Karpouzas, D. G. (2011)Two bacteria identified as Pseudomonas putida and Acinetobacter rhizosphaerae able to rapidly degrade the organophosphate (OP) fenamiphos (FEN) were isolated. Denaturating gradient gel electrophoresis analysis revealed ... -
Key parameters and practices controlling pesticide degradation efficiency of biobed substrates
Karanasios, E.; Karpouzas, D. G.; Tsiropoulos, N. G. (2012)We studied the contribution of each of the components of a compost-based biomixture (BX), commonly used in Europe, on pesticide degradation. The impact of other key parameters including pesticide dose, temperature and ... -
Leaching of the organophosphorus nematicide fosthiazate
Karpouzas, D. G.; Pantelelis, I.; Menkissoglu-Spiroudi, U.; Golia, E.; Tsiropoulos, N. G. (2007)Fosthiazate is an organophosphorus nematicide which was recently included in Annex I of the Directive 91/414/EEC under the clause that it should be used with special care in soils vulnerable to leaching. Thus, the leaching ... -
Liquid chromatographic determination of fosthiazate residues in environmental samples and application of the method to a fosthiazate field dissipation study
Tsiropoulos, N. G.; Likas, D. T.; Karpouzas, D. G. (2005)A method was developed and validated for the determination of residues of the organophosphorus nematicide fosthiazate in soil and water by using reversed-phase liquid chromatography with UV detection. Good recoveries (> ... -
Novel biomixtures based on local Mediterranean lignocellulosic materials: Evaluation for use in biobed systems
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G.; Menkissoglu-Spiroudi, U. (2010)The composition of biomixtures strongly affect the efficacy of biobeds. Typically, biomixture consists of peat (or compost), straw (SIR) and topsoil (1:2:1 by volume). Straw guarantees a continuous supply of nutrients and ... -
On-farm biopurification systems for the depuration of pesticide wastewaters: recent biotechnological advances and future perspectives
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G. (2012)Point source contamination of natural water resources by pesticides constitutes a serious problem and on-farm biopurification systems (BPS) were introduced to resolve it. This paper reviews the processes and parameters ... -
Optimization of Biomixture Composition and Water Management for Maximum Pesticide Dissipation in Peat-Free Biobeds
Karanasios, E.; Papadi-Psyllou, A.; Karpouzas, D. G.; Tsiropoulos, N. G. (2012)Biomixture composition and water management are key factors controlling biobeds performance. Although compost-biomixtures (BXs) possess high degradation efficiency, their low water-holding capacity compared with peat-biomixtures ... -
Persistence and efficacy of spinetoram against three major stored grain beetle on wheat
Vassilakos, T. N.; Athanassiou, C. G.; Tsiropoulos, N. G. (2015)The insecticidal efficacy of spinetoram at concentrations of 0.1, 1 and 5 ppm on wheat was investigated against adults of three major stored-grain species, Sitophilus oryzae (L), Rhyzopertha dominica (F.) and Tribolium ... -
Persistence of pendimethalin in cotton fields under sprinkler or drip irrigation in central Greece
Tsiropoulos, N. G.; Lolas, P. C. (2004)The dissipation of pendimethalin was investigated in soils of cotton fields in Thessaly, central Greece, for a period of two years. The fields were irrigated either with sprinkler or with sprinkler for the first two ... -
Pesticide enrichment factors and matrix effects on the determination of multiclass pesticides in tomato samples by single-drop microextraction (SDME) coupled with gas chromatography and comparison study between SDME and acetone-partition extraction procedure
Amvrazi, E. G.; Papadi-Psyllou, A. T.; Tsiropoulos, N. G. (2010)In this study a single-drop microextraction (SDME) method was extended for the determination of multiclass pesticides (metribuzin, vinclozolin, fosthiazate, procymidone, fludioxonil, kresoxim-methyl, fenhexamid, iprodione, ... -
Quantitative and qualitative differences in the metabolism of pesticides in biobed substrates and soil
Karanasios, E. C.; Tsiropoulos, N. G.; Karpouzas, D. G. (2013)Biobed substrates commonly exhibit high degradation capacity. However, degradation does not always lead to detoxification and information on the metabolic pathways of pesticides in biobeds is scarce. We studied the degradation ... -
