Modeling wine preferences by data mining from physicochemical properties
A data mining approach to predict human wine taste preferences that is based on easily available analytical tests at the certification step is proposed, which is useful to support the oenologist wine tasting evaluations and improve wine production.
The current status and environmental impacts of glyphosate-resistant crops: a review.
Glyphosate-resistant crops have promoted the adoption of reduced- or no-tillage agriculture in the USA and Argentina, providing a substantial environmental benefit and the development and use of failsafe introgression barriers in crops with such linked genes is needed.
Coca and poppy eradication in Colombia: environmental and human health assessment of aerially applied glyphosate.
The risk assessment concluded that glyphosate and Cosmo-Flux did not present a significant risk to human health and the environment, and human health risks associated with physical injury during clear-cutting and burning and the use of pesticides for protection of the illicit crops were judged to be considerably more important than those from exposure to glyphosate.
Review of potential environmental impacts of transgenic glyphosate-resistant soybean in Brazil
Transgenic glyphosate-resistant soybeans have been commercialized and grown extensively in the Western Hemisphere, including Brazil, and four weed species have evolved resistance to glyphosate in GRS in Brazil and have great potential to become problems.
HPLC Screening and GC-MS Confirmation of Triazine Herbicides Residues in Drinking Water from Sugar Cane Area in Brazil
The extensive use of chlorotriazines as selectiveherbicides in agriculture and their relatively highpersistence imply that these compounds are now presentin the environment, contaminating surface and
This section provides a separate section for glyphosate because of the relatively large amount of information on the effects of this very important herbicide on plant diseases and the fact that there have been many seemingly conflicting claims of the effect of glyphosate on diseases in glyphosate-resistant crops.
Changes in Ochratoxin A concentration during winemaking
The effects of common winemaking procedures on ochratoxin A (OTA) concentrations in the Portuguese wine Vinho Verde were studied. Natural contamination of grapes was not observed, so grapes for
Herbicide leaching on a recharge area of the Guarany aquifer in Brazil.
The leaching potential of tebuthiuron, diuron, atrazine, simazine, 2,4-D, picloram, and hexazinone has been evaluated using CMLS-94, "Chemical Movement in Layered Soil," as simulation model and no leaching into the depth of the water table at 40 m was found.
Microwave-assisted solvent extraction and analysis of shikimic acid from plant tissues
A better method for determination of shikimate in plant tissues is needed to monitor exposure of plants to the herbicide glyphosate and to screen the plant kingdom for high levels of this valuable phytochemical precursor to the pharmaceutical oseltamivir.
Tabanone, a New Phytotoxic Constituent of Cogongrass (Imperata cylindrica)
Bioactivity-guided fractionation of this extract using silica gel column chromatography led to the identification of megastigmatrienone, 4-(2-butenylidene)-3,5,5-trimethyl-2-cyclohexen-1-one (also called tabanone), as a mixture of four stereoisomers responsible for most of the activity.
