Dual Sprayer for Pesticides and Fertilizers

Pesticides, Fertilizers and Food Safety

Transferability of six pesticides from agricultural sprayer surfaces.

Secondary exposure to pesticide residues on the external surfaces of sprayers does not currently form part of the risk assessment process. A measure of the ease with which residues may be transferred from the sprayer surface to the operator would enhance the accuracy of any such assessment. This study quantified the dislodgeability of six pesticides from sprayer surfaces in order to calculate t...

Bio-fertilizers and Bio-pesticides Research and Development at Uplb

With the establishment of the National Institutes of Biotechnology and Applied Microbiology (BIOTECH), University of the Philippines Los Baños (UPLB) researches were done to look for cheaper and locally available but efficient substitutes or supplements to inorganic fertilizer, such as bio-fertilizers and bio-pesticides. Technologies on bio-fertilizers developed by UPLB include BIO-N, the most ...

Microfabricated dual sprayer for on-line mass tagging of phosphopeptides.

Phosphopeptides tagging reactions by dinuclear zinc(II) complexes (1,3-bis[bis(2-pyridylmethyl)amino]-propan-2-olato dizinc(II)3+, called tag) were performed with a dual-channel microsprayer in electrospray ionization mass spectrometry. The reaction is first studied ex situ and analyzed with a commercial electrospray source. In situ reactions (i.e., inside the Taylor cone) were achieved with a ...

Part Three PREVENTION AND CONTROL OF WATER POLLUTION FROM FERTILIZERS AND PESTICIDES

The introduction in a number of UN/ECE countries of new legislation to control and reduce water pollution from point sources was aimed at achieving stricter measures for pollution prevention at source, as well as the implementation of add-on measures such as advanced sewage treatment. In countries where such legislation has been introduced, both the relative and the absolute contribution of emi...
