title: Dissipation and residue of clothianidin in granules and pesticide fertilizers used in cabbage and soil under field conditions.
abstract: The single application of 0.5 % clothianidin granules, a novel formulation, was used to control pests in vegetables under a high dose. In this article, residues of clothianidin in cabbage and soil samples under field conditions from Guangzhou, Nanning, and Qianjiang were determined by HPLC. The terminal residues of clothianidin in cabbage were less than the limit of detection (<LOD) at pre-harvest intervals of 30 days, and these values were lower than the maximum residue limit of 0.2 mg kg-1in cabbage set by the Codex Alimentarius Commission. To test on the influence of the pesticide fertilizers' effect on clothianidin residual, clothianidin granules and fertilizers of chicken manure, urea, and organic fertilizer were mixed into different pesticide fertilizers through their normal field using dosage and evaluate residual influence of clothianidin in different formula. After analysis of variance of the effect factors, the effect of different pesticide types on half-life was not significant, but the effect of sample types was significant. Clothianidin granules and pesticide fertilizers could be safely applied in cabbage under a single high-dose administration.
