“…Moreover, the efficiency of these Si sources was always increased by increasing their concentrations and they completely suppressed the fungal growth at 200 ppm. The positive effect of these Si sources was found also by several researchers on several pathogenic fungi, including R. solani , Rachniyom and Jaenaksorn 2008, Bekker et al,2009, Li et al, 2009, Shen et al, 2010and Nada, 2014 Potassium silicate at 10, 25 and 100 ppm, was more effective than the others silicon compounds in suppressing the fungal growth. This finding was supported by the aforementioned investigators, who reported that Ps was an effective silicon source in suppressing pathogenic fungi.…”

“…These results are similar to those reported by Subbiah et al, (1996), Voltiolina, (2001 and Zaki and Waleed (2008). In this respect, R. solani is considered as important and dangerous soilborne fungal pathogen affecting different medicinal and aromatic plants (Minuto et al, 1997, Hilal et al, 1990, Hilal et al, 1994, Hilal et al,1998, Hilal et al, 2009, Conway et al, 1992and Conway et al , 1997, Machowicz-Stefaniak et al, 2002, Kalra et al, 2004, Yadav and Anamika, 2005and Nada, 2014and Nada, 2015.…”

“…Rhizoctonia solani diseases (damping -off, root rot and /or aerial blight) caused severe losses in vegetative growth and stand of seedlings and plants as well as considerable reduction in sage plant yield (Subbiah et al, 1996, Voltolina, 2001and Zaki and Waleed, 2008. Also, Rhizoctonia diseases infection yielded the same negative impact on other medicinal and aromatic plants (Hilal et al, 1998, Hilal and Baioumy, 2000, Conway et al, 1992and Conway et al, 1997, Bano et al, 2012and Nada, 2014and 2015.…”

Isolation trials from infected sage seedlings and plants, growing in Ismailia, North Sinai and Qalubyia governorates, showing symptoms of damping-off and root rot diseases yielded Fusarium oxysporum, F. solani, Macrophomina phaseolina, Pythium ultimum and Rhizoctonia solani. However, R. solani recorded the highest frequency in isolation (52.6%), followed by Fusarium solani (24.6%), while M. phaseolina was the least (3.5%). These fungi were found to be pathogenic to sage seedlings. Rhizoctonia solani followed by F. solani were the most virulent fungi, causing the highest damping-off incidence. Three silicon (si) sources, i.e. calcium silicate, potassium silicate and sodium silicate with four concentrations (25, 50, 100 and 200 ppm) significantly inhibited the in vitro growths of R. solani in different degrees. Potassium silicate was more effective than the other silicon sources tested, and completely inhibited mycelial growth at 200 ppm. Soaking seeds (30 min.) and /or dipping treatment for seedlings (30 min.) in each of these silicon sources (400 ppm) or the fungicide Vitavax /Thiram (3 g/l water) gave sufficient control to R. solani diseases, i.e. damping-off in greenhouse and nursery as well as root rot in the field .Also, they recorded significant increases in growth parameters of seedlings (height & root length) and mature plants (height & no. of branches /plant). Potassium silicate, however, was significantly the most effective treatment among other silicon sources. Using calcium silicate and potassium silicate as dipping treatment for seedlings, gave significant increases in yields of fresh herb and essential oil content. Vitavax /Thiram treatment in the nursery and field experiments was more effective than silicon treatments, except with potassium silicate in the field, which increased fresh herb weight per plant and essential oil content than the fungicide.

Background: Due to the increased economic and social benefits of the strawberry crop yield in Egypt, more attention has been paid to control its pests and diseases. Leaf blight, caused by the fungus Phomopsis obscurans, is one of the important diseases of strawberry plants. Therefore, effect of silicon and potassium, sodium and calcium silicates, and a fungicide on Phomopsis leaf blight of strawberry under laboratory and field conditions was examined. Results: Four concentrations, i.e., 0, 2, 4, and 6 g/l of silicon as well as potassium, sodium and calcium silicates could significantly reduce the linear growth of tested fungus in the laboratory test where complete inhibition of linear growth was obtained with 6 g/l. The other concentrations showed less but favorable effects. The highest reduction of disease severity was obtained with potassium silicate and calcium silicate separately applied as soil treatment combined with foliar spray which reduced the disease incidence by 83.3 and 86.7%, respectively. Other treatments showed significant (P ≤ 0.05) but less effect. The highest yield increase was obtained with potassium silicate and calcium silicate applied as soil treatment combined with foliar spray which increased fruit yield by 60 and 53.8%, respectively. All tested treatments increased (P ≤ 0.05) the activities of the peroxidase, polyphenol oxidase, and chitinase enzymes. Conclusions: All tested concentrations of silicon salts have suppressed the fungal growth and disease spread but with different degrees. The more the concentration, the better it suppresses the fungal growth and consequent effect on damaging strawberry plants. Potassium silicate and calcium silicate separately applied as soil treatment combined with foliar spray were the best in reducing the disease incidence and increasing crop yield. Potential implications of silicate salts on enhancing activities of the tested enzymes reflected their role in protection against such a plant disease.
