The purpose of this research was to study the effect of varying dosages of insecticide and fungicide on the conservation of stored seeds. The products and dosages for each 1000Kg of seeds were: 1) control; 2) aniline (936mL); 3) aniline (936mL) + Thiabendazole (120g) + Dicarboximida (187.5g) + Pirimifos- methyl (6.25mL) + Deltamethrin (0.75mL); 4) aniline (936mL) + Thiabendazole (240g) + Dicarboximida (375.0g) + Pirimifos- methyl (12.50mL) + Deltamethrin (1.50mL); 5) aniline (936mL) + Thiabendazole (480g) + Dicarboximida (750.0g)+ Pirimifos- methyl (25,00mL) + Deltamethrin (3.00mL); 6) aniline (936mL) + Thiabendazole (960g) + Dicarboximida (1500,0g) + Pirimifos- methyl (50.00mL) + Deltamethrin (6.00mL). The seeds were analyzed for moisture content, germination and vigor (accelerated aging and cold tests) at 0, 6, 9 and 12 months of storage. From the information obtained we can conclude that the chemical treatment applied tended, with the increase of dosages, to produce latent effects unfavorable to the seed performance, that were intensified with the prolongation of the storage period.
