Evaluation of endosulfan residues in vegetables grown in greenhouses.
The reduction in residue levels of endosulfan with time after treatment of tomatoes, green beans, peppers and cucumbers grown in different types of commercial greenhouses (flat- and asymmetric-roof greenhouses) in Almería (Spain) was investigated. A study of the major and minor degradation products of endosulfan in peppers and cucumbers (endosulfan-sulfate, -ether and -lactone) was carried out ...
متن کاملPhytochemical phenolics in organically grown vegetables.
Fruit and vegetable intake is inversely correlated with risks for several chronic diseases in humans. Phytochemicals, and in particular, phenolic compounds, present in plant foods may be partly responsible for these health benefits through a variety of mechanisms. Since environmental factors play a role in a plant's production of secondary metabolites, it was hypothesized that an organic agricu...
متن کاملDetermination of diagnostic standards on saturated soil extracts for cut roses grown in greenhouses
This work comprises the theoretical determination and validation of diagnostic standards for the analysis of saturated soil extracts for cut rose flower crops (Rosa spp.) growing in the Bogota Plateau, Colombia. The data included 684 plant tissue analyses and 684 corresponding analyses of saturated soil extracts, all collected between January 2009 and June 2013. The tissue and soil samples were...
متن کاملCrop Specific Application Rates of Nitrogen for Soil-Grown Crops in Greenhouses to Protect the Groundwater
In a desk study, nitrogen (N) fertilizer application rates were studied and Nconcentrations at one meter depth or at the drain were estimated for Chrysanthemum grown in twelve greenhouse cropping systems, differing in soil type, supplemental lighting and transmissivity. Two N-saving strategies were also studied of which one estimated the N-concentration in the irrigation water to comply with th...
متن کاملEvaluation of Diazinon and Oxydemeton-methyl Residues by GC/NPD in Tomatoes Grown in Kerman Greenhouses
Pesticides are one of the major pollutants in the environment. The residue of pesticides has been reported to be at a critical level in agricultural crops, especially in greenhouse crops. Tomato is considered as an important vegetable in Iranian food basket and is produced in fields and greenhouses. So, the current study aimed to assess diazinon and oxydemeton-methyl levels in tomatoes sampled ...
