Citrus Brown Rot (BR), caused by Phytophthora spp., provokes important economical losses mainly in periods of high rainfall. The management of this disease in Florida and Brazilian citrus areas, main orange growers worldwide, ...

Raman spectroscopy is emerging and powerful technique for identifying oxyanions of phosphorus, but it still is not straightforward applied to identify and quantify simultaneously phosphite and phosphate species in solution. ...

The hydrolysis reaction mechanism of phosphite antioxidants is investigated by liquid chromatography-mass spectrometry (LC/MS). The phosphites were chosen because they differed in chemical structure and phosphorus content. ...
