This paper described an organic solvent-free, rapid, simple, and space-saving method of sample preparation followed by HPLC coupled photo-diode array (PDA) detector for simultaneous quantification of cyromazine (CYR) and its decycropropylated metabolite, melamine (MEL), in milk. The HPLC-PDA was performed on an Inertsil® HILIC column with an isocratic aqueous mobile phase. Analytes were extract...

The intensive production of horticultural crops generates large amounts agricultural biomass (BA), which is burned in the openfield or deposited landfills becoming an environmental problem, especially if they are contaminated by pesticide residues. Thestudy aimed to evaluate presence pesticides BA bell pepper, jalapeño and poblano using aQuEChERS method coupled LC/MS-MS GC/MS/MS. An analysis ma...

The effect treatments with the recommended application rates of avermectin, buprofezin, white oil, lambda-cyhalothrin and cyromazine on Trialeurodes vaporariorum Westwood (Aleyrodidae: Homoptera) was evaluated. Pesticides were applied against larvae infesting brinjal (Solanum melongena L.) and tomato (Lycopersicon esculentum Mill) plants in a natural environment of the Cameron Highlands, Pahang...
