  • Complete inhibition of fungal linear growth was observed with 4 and 6 g/l for R. solani and F. solani, respectively, in the laboratory. Under field conditions, all tested concentrations significantly reduced the disease incidence and severity. The highest reduction of such disease incidence and severity was obtained with potassium silicate and calcium silicate applied separately as soil treatment combined with foliar sprays which reduced the disease incidence and severity by 92.7 and 91.9, and 91.7 and 91.1%, respectively. The highest yield increase, i.e., 77.1 and 72.8%, was obtained with potassium silicate and calcium silicate, respectively, applied as soil treatment + foliar spray....

  • 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...
