Physiological and Biochemical Variations in Celery by Imidacloprid and Fenpyroximate

Pesticides are one of the abiotic stresses that have had an impact on quality agricultural products, especially in China. This study was first to explore soluble protein (SP) accumulation, peroxidase (POD) activity, and superoxide dismutase (SOD) activity variations stem leaf celery plants field after 2 h, 1, 3, 5, 8, 10, 14, 21, 28-day spraying imidacloprid (IMI) fenpyroximate (FEN) at various doses. The findings demonstrated there no notable difference ultimate residues between 1 F 10 F, even with treatment, were not a concern. SP accumulation alterations mainly provoked by residues, which dramatically boosted eventually declined leaf. POD dynamic process marked shift (enhanced declined) when compared non-pesticide treatment 28 days. trial exhibited SOD principally positioned whether pesticides applied or not, might be due distinctive structure stem. No obvious linear relation application dose observed.
