This work evaluated the effect of industrial treatment with different pesticides and seed sizes in the physiological performance of sweetcorn and the content of active ingredients of insecticides before and three months after storage. Four seed lots of a sweetcorn single-cross hybrid (L1, L2, L3 and L4) and different sieves (S1, S2 and S3) were used for two experiments. Experiment 1: industrial seed treatment, T1=untreated seed (control), T2= Maxim Advanced®, T3= Cruiser® 350 FS and T4= Poncho®. Experiment 2: quantification of the content of active ingredients, commercial products Cruiser® 350 FS and Poncho and the efficiency of distribution were measured using HPLC-UV. The results showed that industrial seed treatment with Maxim Advanced®, Cruiser® 350 FS and Poncho® can be performed three months before sowing without damage to sweetcorn seeds HPLC is efficient in quantifying the content of active ingredients on sweetcorn seeds treated with Cruiser® 350 FS and Poncho®. The industrial seed treatment shall be calibrated for each lot, which is justified by the different amounts of active ingredient between lots and seed sizes.
