The Sage plant belonging to the family Lamiaceae is one of the
medicinal and aromatic plants which are receiving considerable attention all
over the world due to their vast untapped economic potential, especially in
the use of herbal medicines. This study carried out to control root rot and
wilt disease of sage plant using copper oxide nanoparticles (CuONPs); zinc
oxide nanoparticles (ZnONPs) and vascular arbuscular mycorrhiza (VAM).
According to identification procedures, fungal isolates obtained belonged to
Fusarium solani, Rhizoctonia solani and Macrophomina phaseolina. Under
laboratory conditions, the growth of the tested fungal isolates (R. solani
(Rs9), F. solani (Fs3) and M. phaseolina (Mp11)) was reduced with the
application of ZnONPs and CuONPs compared with the control treatment.
Also, application of VAM and CuONPs (at 250 ppm) as alone treatment
significantly decreased percentage disease incidence and percentage of
disease severity of sage root rot/wilt disease, at 30 or 90 days from sowing.
Meanwhile, combination between VAM and CuONPs were the most
affectivity compared with alone treatment. At the same time, the plant
growth parameters and seed yield of sage plants improved.
