A simple method based on solid-phase extraction combined with liquid chromatography for simultaneous determination of nine triazine herbicides (ametryn, atrazine, cyanazine, prometryn, propazine, simazine, simetryn, terbuthylazine, and terbutryn) in surface water samples was developed and validated. Under optimized conditions, 50 mL of water sample was pumped through the Oasis HLB cartridge, an...

Post-planting weed control methods on abandoned farmland were studied in three fi eld trials in southern Finland using a completely randomized design with four treatments and 30 to 40 replications. Mulches of 60 × 60 cm [sheet mulch – strips of plane waste and plastic fi bre, newspaper – waste paper slurry, wood chips, pure wood fi bre slurry], herbicides [i.e. glyphosate or terbuthylazine alon...

Prickly sida is a troublesome annual weed native to the USA. It was introduced in Greece over two decades ago and has since been infesting cotton crops, where it proved difficult control. A two-year field study (2021–2022) conducted (Karditsa, central Greece) heavily infested with prickly evaluate efficacy of nine treatments against this weed, using pre-emergence (PRE) early post-emergence (EPO...

Sucul sistemlerin pestisitlerle kontaminasyonu son yılların en önemli çevre problemidir ve içme suları sulama için bir riskdir. Aşırı pestisit kullanımı sucul kontaminasyonuna neden olur. Herbisitlerin direkt toprağa uygulanması da topak suların kirlenmesi noktasında daha önemlidir. Bu çalışmanın amacı -Çanakkale İli-Batakovası bölgesinden örneklenen sediment su örneklerinde herbisit kalıntılar...

Inside the framework of Analytical Quality by Design, a model-based approach has been developed and used to identify operating conditions (control method parameters) related composition flow rate mobile phase for liquid chromatographic determination with preset quality characteristics. The starts defining these desired characteristics intended chromatogram (proper resolution consecutive peaks s...

Aim. This work is devoted to the search for potential partners integrated application of flumioxazine in sunflower crops. herbicide an inhibitor protoporphyrinogen oxidase (PPO) weed plants. The resistance this class herbicides not yet common today, compared other classes. Therefore, aimed at de- veloping flumioxazine-based compositions that effectively prevent emergence herbicide-resistant bio...

The use of agricultural drainage water (ADW) in irrigation is a great challenge, improving efficiency, nutrient circularity, and avoiding surface ground-water contamination. objective this study was to evaluate the chemical ecotoxicological characteristics an ADW analyze safety its reuse. An irrigated area with maize crops selected (Tejo Basin, Portugal), where subsurface structure for recovery...

The worldwide increase in the number and use of agrochemicals impacts nearby soil freshwater ecosystems. Beyond excess applications dosages, inadequate management remnants rinsing water containers application equipment worsen this problem, creating point sources pollution. Advanced oxidation processes (AOPs) such as photocatalytic photo-oxidation have been successfully applied degrading organic...

incubation studies. Although Walker’s model was generally found to overestimate total soil residues at later Data collected from a 3-yr controlled field study in Hamilton, New sampling dates (Walker, 1987), Heiermann et al. (1995) Zealand were used to examine whether the Root Zone Water Quality Model is capable of predicting water movement and pesticide fate in reported that this model greatly ...
