Quality of sweet corn seeds treated before and after storage

Abstract

This work aims to evaluate the effect of industrial treatment with different chemicals and also seed sizes on the physiological behavior of sweet corn in addition to evaluating the content of active ingredients of insecticides before and three months after storage. Four lots of a single sweet corn cross hybrid (L1, L2, L3 and L4) and different sieves (S1, S2 and S3) were carried out in two experiments. Experiment 1: industrial seed treatment, T1 = untreated seeds (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 distribution efficiency was measured by HPLC-UV. The results showed that industrial seed treatment with Maxim Advanced®, Cruiser® 350 FS and Poncho® can be carried out three months before sowing without damaging sweet corn seeds. HPLC is efficient to quantify the content of active ingredients in sweet corn seeds treated with Cruiser® 350 FS and Poncho®. The industrial seed treatment was calibrated for each batch, which is justified by the different amounts of active ingredient between batches and seed sizes.
