    The oil palm (Elaeis guineensis) is a tropical plant typical of warm climates that grows in lands below 500 meters above sea level. In Colombia, the crop is present in four zones: North, East, Central and South West, its planted area is approximately 500,000 hectares. Hybrid seed production can verses affected by the presence of fungi in the germination process. For this reason, phytosanitary controls and chemical treatments have been used, however, the conditions in which the seeds can be germinated allow the growth of fungi. The objective of this research was to develop a coating based on specific residues from the palm oil extraction process for the coating of hybrid seeds, maintaining their useful life. For this, different ratios of alginate, gum arabic, gelatin, glycerol, palm residues (fiber and tusa) and antimicrobial extracts of lemon balm and eucalyptus were evaluated to find the best matrix to protect the seeds and prevent fungal contamination. The allowed results showed that the best matrix was gelatin alginate due to its durability in the seed, fungal mitigation and fewer cracks. On the other hand, it was found that the RC2T4 treatment presented greater durability in the seed and fungal mitigation in 77%.
