Nanopartículas de plata recubiertas con quitosano contra la marchitez vascular causada por Fusarium oxysporum en plantúlas de tomate



Palabras clave:

silver nanoparticles, Fusarium oxysporum, tomato wilt


Fusarium wilt  in tomato seedlings is of great economic importance throughout the world due to the significant losses it causes in the crop. Advances in nanotechnology provide alternatives that can be applied in the control of pathogens. Silver nanoparticles (AgNP) stabilized with chitosan (Cs) are currently in widespread use for the control of plant pathogens.  The objective of the present investigation was to determine the effect of the application of Ag-Cs NPs on the tolerance of tomato seedlings and control of the vascular wilt caused by Fusarium oxysporum. The results showed that the application of the NPs did not show negative effects in the normal vegetative development of the tomato seedlings, in addition the treatment was effective to reduce the severity of the disease in inoculated Fusarium oxysporum seedlings.
