Abstract
BACKGROUND: The present work involved the synthesis and characterisation of mesoporous alumina sphere (MAS) nanoparticles to evaluate their biological activity against tomato root rot caused by Fusarium oxysporium, as compared with the recommended fungicide, tolclofos-methyl, under laboratory and greenhouse conditions. The effects of MAS nanoparticles on the growth of tomato plants were also evaluated and compared with those of tolclofos-methyl. RESULTS: The physical characteristics and structural features of MAS nanoparticles, such as their large surface-area-to-volume ratio, active surface sites and open channel pores, caused high antifungal efficacy against F. oxysporium. MAS nanoparticles presented an antifungal potential similar to that of tolclofos-methyl and much greater than that of the control under both laboratory and greenhouse conditions. The highest growth parameters were recorded in tomato plants treated with MAS nanoparticles, followed by those treated with tolclofos-methyl. CONCLUSIONS: Our study demonstrated the possible use of cylindrically cubic MAS nanoparticles as an effective alternative for the control of Fusarium root rot in tomato.
