The Effects of Foliar Sprays with Different Silicon Compounds

Henk-Maarten Laane. Plants (Basel). .

Abstract

The use of foliar sprays with silicon compounds is relatively new. Initially (in 1990) foliar sprays with silicates were used. In 2003, foliar sprays with (stabilized) silicic acid were introduced, and more recently foliar sprays with silica nanoparticles have also been applied. Foliar sprays with silicates are effective as pesticides, while (stabilized) silicic acid sprays increase growth and yield and decrease biotic and abiotic stresses. The limited data on foliar silica-nano sprays show a tendency to decrease biotic stress and to stimulate a limited increase in growth and yield.

Keywords: abiotic stress; biotic stress; foliar spray; growth; quality; silica nanoparticles; silicates; stabilized silicic acid; yield.

Figure 1
The effects of foliar application of PEG-sSA on wheat grown in very saline soil (area of 3 ha) in Romania during 2014. Half of the plot was sprayed four times with AB Yellow® (=4 mL/L PEG-sSA plus B, Mo and Zn). The visual differences between the sprayed plants (taller plants) and the control (small plants) can be seen.

Rice plants grown on very acidic soil on a plot of 1.5 ha near Chennai (India), 2017. Half of the plot was sprayed with PEG-sSA. The visual differences between sprayed plants (a) and the control (b) can be seen.
