efecto de la aplicación de nanopartículas de iones de cobre sobre el crecimiento de fusarium sp proveniente de la piña.

Abstract

Phytosanitary controls to improve agricultural production have evolved over time, due to the fact that pathogenic microorganisms have become resistant to traditional fungicides, reducing its effect. Copper has always been used to control bacteria and fungi, and many fungicides have copper as its active compound, the difference is the copper’s presentation, as salt, sulfates, oxides or nanoparticles. Metal nanoparticles are important in the agronomic industry because they have a better effect than metal traditional size, requiring a lower concentration and reducing the adverse effect that metal may have on health and the environment. Copper nanoparticles have had successful results as fungistatic and fungicidal agents against various fungi genus pathogens, Fusarium is one, by in vitro conditions. Therefore, this research focused on analyzing the effect of copper ion nanoparticles on Fusarium sp from pineapples Ananas comosus L, specifically the commercial cultivar MD-2, to determine its effect as an inhibitory agent of fungal growth. For the development of this study, post-harvest degraded pineapples were used to isolate the fungal strains, detect the presence of Fusarium sp and analyze its effects on the overall quality of the pineapple.
