PESQUISAS ACERCA DA MICROENCAPSULAÇÃO DE Trichoderma harzianum PARA CONTROLE BIOLÓGICO

Abstract

The growing demand for sustainable alternatives to the intensive use of chemical pesticides has driven the development of biotechnological strategies for plant disease management. In this context, the microencapsulation of Trichoderma harzianum emerges as a promising approach to optimize its application in the biological control of phytopathogens, particularly considering the global agricultural losses associated with environmental stresses such as UV radiation, temperature fluctuations, and desiccation. The literature analysis highlights that techniques such as spray drying, complex coacervation, and especially ionic gelation show strong potential for protecting conidia, with emphasis on the use of polymeric matrices combined with additives such as clays and nanocellulose, which contribute to enhanced stability and controlled release of the microorganism.The results indicate that microencapsulation not only extends the shelf life of bioinputs but also significantly improves viability and biocontrol efficiency under field conditions, consolidating its role as a key strategy for sustainable plant disease management.
