| dc.description.abstract | The aim was to investigate the residue concentrations of spirotetramat and metalaxyl-M in greenhouse tomatoes when applied alone or in combination. To determine if there is a change in dissipation measured, followed the interaction when both chemicals were applied. This study also aimed to investigate tomato juice residues of spirotetramat and metalaxyl-M post-heat treatment, when applied alone versus in combination.
A literature review was performed to gain in-depth knowledge regarding the aim of the study and the two pesticides used. Spirotetramat is the active ingredient in Movento, and metalaxyl-M in Ridomil Gold. Previous studies have proved the dissipation of a chemical, but there is a vast array regarding our topic when spirotetramat and metalaxyl-M are used in combination.
The experiment was carried out using greenhouse tomatoes, and the chemicals, spirotetramat and metalaxyl-M, were applied alone and in combination before measuring the residue concentrations — techniques such as Sigma-Aldrich. Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) kits I-II, IKA T-25 Ultra-Turrax® Labrotory homogenizer, by a Phenomenex Kinetex C18, Electrospray (ESI) ionization, and LC-MS measured the pesticide concentration. | en_US |
