Abstract Kasugamycin (KSM), an aminoglycoside antibiotic, has been widely used as a natural fungicide to control plant diseases, particularly for managing rice blast. However, its uptake mechanism and transport in remain be explored. In this article, seedlings were treated by the foliar spraying method, content of KSM leaves, stems roots under different treatments was detected high‐performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS), respectively. Results showed that leaf‐applied could transported phloem migrate after leaves. Concentration, temperature pH had significant effects on KSM. Compared with control, competitive inhibitors d ‐glucose phlorizin both inhibited KSM, demonstrating sugar transporter proteins involved process. The energy dinitrophenol (DNP) carbonyl cyanide chlorophenylhydrazone (CCCP) also significantly indicating required consumption. Thus, active process involving proteins, it downward through phloem. This study contributes promotion scientific application antibiotics biological crop diseases. It will provide theoretical basis development root‐targeted pesticides mobility.

Abstract Pesticide residues have always been one of the food safe issues troubling consumers. Agricultural production is usually accompanied by a mixture pesticides, and pesticide are not only present on plants but also contaminate soil in environment. In this study, 15 pesticides commonly found cowpea were analyzed optimizing QuEChERS combining GC-MS/MS HPLC. Various extractants different methanol water ratios evaluated to extract from soil.C18, PSA GCB used purify extracts, while de-watering agent NaCl optimized. The average recoveries 91.81-109.95% 89.89-104.08% at spiked levels 0.0-1.0 mg/kg 0.1-10.0 mg/kg, respectively. This method suitable for detection types (red soil, yellow sandy loam paddy soil) tissues. addition, detected cowpea- system. demonstrates that developed can be detect multiple various soils crops, provides necessary technical support agricultural product safety supervision.
