Most silica products on the market can be applied as a root feed or as a foliar spray. Plants can absorb much more through foliar feeding than just absorption through the root zone. Silica is also known to prevent powdery mildew when used as a foliar spray. If using silica as both a foliar and a root feed, be careful not to overdose the plants.
