Health and environmental impacts of glufosinate ammonium

Glufosinate ammonium-induced pathogen inhibition and defense responses culminate in disease protection in bar-transgenic rice.

Glufosinate ammonium diminished developments of rice (Oryza sativa) blast and brown leaf spot in 35S:bar-transgenic rice. Pre- and postinoculation treatments of this herbicide reduced disease development. Glufosinate ammonium specifically impeded appressorium formation of the pathogens Magnaporthe grisea and Cochliobolus miyabeanus on hydrophobic surface and on transgenic rice. In contrast, con...

A review of scientific evidence on the environmental impacts of growing genetically modified herbicide tolerant crops relevant to the UK

Herbicide tolerant (HT) crops are not a new phenomenon – in fact, all crops are to some extent tolerant to herbicides. Many herbicides are dose-specific for particular plant groups, for example grasses, and these can be used on broad-leaved crops like potatoes and oilseed rape without causing unacceptable harm. This is the basis for most current agricultural practice in developed countries. Gen...

Field Dissipation and Storage Stability of Glufosinate Ammonium and Its Metabolites in Soil

A simple analytical method was developed to measure concentrations of glufosinate ammonium and its metabolites, 3-methylphosphinico-propionic acid (MPP) and 2-methylphosphinico-acetic acid (MPA), in field soil samples. To determine the minimum quantification limit, samples were spiked at different levels (0.1, 0.5, and 1.0 mg/kg). Soil samples were extracted with ammonium hydroxide solution 5% ...

A Case of Anterograde Amnesia with Bilateral Hippocampus Involvement After Acute Glufosinate Ammonium Intoxication

Glufosinate ammonium is a commercial herbicide made from a phosphinic acid derivative of glutamate, which leads to a lethal accumulation of ammonia in plants by inhibiting the activity of glutamine synthetase (1). As the use of glufosinate-ammoniumcontaining herbicides has increased, so too has the incidence of acute intoxication through accidental or purposeful (attempted suicide) ingestion of...
